Test 7 - Is your car a Dodge Neon or a Ford 6.0L diesel? Congratulations, Your head gasket is blown

Love the 60 lounge music playing in the background. I almost started drinking a Martini while sitting in front of my Magnavox color TV.

I did all those tests and could not find my blown gasket - but the following test showed the problem - remove radiator cap and bring level into view - bring a cylinder u want to test to top dead center on ignition stroke [both valves closed] put compression test hose or extension [without check valve in it] into spark plug hole - attach shop air to supply shop air at 100 psi into cylinder on a warm engine - observe coolant in radiator for rise in level or bubbles.

A very easy way to tell whether you have a blown gasket is to just remove the oil. If water falls out first then the gasket is blown. Because oil sits on top of water.

Big indicators, milky substance like shown, and the antifreeze overflow container level rises with water and dirty sludgy water. If running long enough water inside gets hot and bubbles from air flowing in. Can cause your container to also crack. Great video!

the way I found out was my subaru exploded

If you drive your car on short hops, that can make the fill plug milky as well. Nothing wrong, just doesn't run long enough to evaporate normal condensation.

more symptoms could be : 1-extensive smog in exhaust 2-coolant level decrease (sometimes you may hear water flow in car cabin specially at ~3000 RPM "when engine is cool") 3-increase engine oil amount 4-uneven engine idling (after engine is cooled - water leaks in engine and makes problems for spark plugs - it wont show when engine is hot) ignoring bad gasket may cause Subsequent problems for your car engine and increase costs !!!

Test number 1, you consistently have to refill the radiator overflow but no fluids are under the vehicle.

Super informative video. Decent sounding dude. Stayed on topic. Points given quickly yet thoroughly. No stupid techno music. Thanks Will sub!

Good stuff. Here's another tip, it happened to me once: I pressurized the cooling system, looking for any water leaks. Well, if your equipment is working well (no air leaks out the pump itself or via the radiator filler neck) the system should maintain a steady pressure reading at about 12 psi (I believe. Sometimes I only fill to 7) if pressure drops within 5 minutes, I look for signs of water, on the ground, around the engine. Well, I didn't see any water anywhere..which lead me to believe that water was being lost inside the motor due to a blown head gasket.

Massive amount of water shooting out the tail pipe is a great indicator

I wish to say thank you I have a vehicle that I'm working on and trying to determine exactly which cylinder has the bypass blown head gasket it is a V8 so I'm going to exactly what you did and try to determine which cylinder it is because it is a V8 so hopefully I've only got to change one side of the head gaskets not both head gaskets so your video it's been very informative thank you for taking the time to make such a great video and you have possibly save me an extreme that time and money thank you

No. 3 on my car.. At first i thought it was just normal.. Tnx for this

I would add to the compression test.... If you also notice a discrepancy between adjacent cylinders in excess of 20 psi, I would consider that vehicle as having a blown Head or may need a Head replacement soon.

the heat matrix leaks water when i put my heater on had some advice and was told also could mean head gasket on it's way out any info on this would be great as im not car minded

Head Gasket blowed in my Car about a month ago and first i thought that i can fix it for myself cos im not a expert for fixing cars n i didnt know how damn huge operation it really is to change Head Gasket but after i saw a video where some dude fix HG in same car than i got,i let a local garage to do it cos with my repairing skills,i would make even more damage 😎 The Car is fixed now and it wasnt cheap ffs but no need to buy a new car so all good 👍 Sry for a crappy English ✌

Okay, I have an 09 PT Cruiser. It recently started bubbling in the reservoir when the car would sit and idle. Changed thermostat, radiator cap twice, and finally the radiator, which did have a leak. However, it still bubbles in the reservoir after I drive it up a large hill and then park. It will bubble and sometimes lose coolant. There is no white smoke, no coolant in the oil, nothing like that. Could this be a cracked head? I get good heat and it never overheats while driving.

Test 1: "Mayonnaise" as its often called, or milky sludge, can occur when a vehicle is driven short distances. The vehicle may not be heating up the oil long enough to burn off natural condensation in the engine. As heat rises, the water vapour will stick to the oil cap and form an emulsion with the oil. You can wipe this goo off with a paper towel or lint free cloth. This condition can be prevented by either taking a long journey once every week or two, or by letting the car idle so it can come up to temperature and burn off this residual condensate. If you get this mayonnaise even after frequent long journeys then the head gasket might be bad. Test 2: If easy and safe to do so on your gasoline vehicle you can remove the fuel pump fuse and let the vehicle run out of fuel, restart the vehicle. When the vehicle is unable to run, you can now remove the spark plugs. Hold a printer page or similar closely over the spark plug hole and have another person crank the engine for a few seconds. If you observe any residue on the page, smell the page to see if its gasoline, if not it will most likely be water from the cooling system. You can add red (or other color) dye to the cooling system to further validate this, if the water on the page is red for example it's a guaranteed sign coolant is entering the combustion chamber. Test 3: When the engine is cool, there should be no bubbles in the radiator or expansion tank. If you see bubbles, combustion gasses are entering the cooling system. In this instance, you car will often present as an overheat condition. If you remove the radiator cap when the engine is at operating temperature (Never do this) the coolant will boil naturally. The radiator cap pressurises the cooling system to prevent the water from boiling. Test 4: As explained. However, in the case of diesel vehicles the solution will turn green indicating a bad head gasket. Test 5: A compression test will tell you if the compression is low, but not why its low. It can be low due to worn rings, bad head gasket, cracked block or head, warped block/head, or valve seat issues. A leak down test will tell you how much air is leaking from the cylinder, and where its leaking to; which is the important thing to know. Test 6: As explained. Test 7: If you checked all of the above and your vehicle is still showing overheat on the instrument cluster, check your temperature sensor and thermostat. A thermostat can stick closed which will cause engine overheating, and over time cause the head gasket to fail. Test 7: If you diagnose a bad head gasket its very important that you discover why the head gasket failed, if you just throw a new head gasket in and fail to rectify a crack in the head for example, you may blow the new head gasket in a matter of days.

Luv the Music💕💕💕

Great quick video!

Also another way to tell your car's got a possible blown head gasket is you are not getting any heat. Since your cooling system is pressurized any loss of it will cause you to get no heat. Though it could be a clogged heater core or not enough coolant as well. Make sure to rule them out.

Very informative. Thank you! 🚘

Hay, I pulled my cylinder head off and found a gap/burn in the gasket between the cylinders. No water in oils or oil in coolant. When I looked down the cylinders and saw no cross hatching, do I need to hone them? Can I hone without taking out the pistons? I wasn't burning oil. Thanks

I used a bottle of Steel Seal to fix my head gasket, drained the coolant, removed the thermostat, flushed the cooling system really good, Then use a radiator cleaner to clean the cooling system , Make sure to flush out all the cleaner 100%, When engine is 100% cold add steel seal with distilled water, turn heater on high & let idle for 30 mins with the radiator cap off........Let it cool for 1 hour the let idle again for 30 mins with the radiator cap on...........next morning let it idle for another 30 mins then removed all water from the system to let the steel seal cure by air contact for 24 hours, Replace the thermostat, fill with coolant and your good to go. Mine has been running perfect for 70k miles now as i use the car for uber & lyft, Only cost me about $120 total.

i have heard that:oil filling cap can be a test method that when be open if the valve ring is leaking there should be air blowing out side from engine>>>Is that right??

Thank you.

2008 impala 3.5 NEVER overheats, but coolant inside the reservoir boils to the point it steams a lot (giving the overheating impression) but steams only from reservoir and at times it spills over. Going to give these tests a try Thx

I'm just wondering if any of these can differentiate between a blown head gasket and a bad oil cooler on a pt cruiser gt.

My 07 Versa became overheated... took it to the mech. Pour some liquid.. it was leaking at the bottom. Fix the hose, n now the ignition coil was filled with oil... it struggled a lil bit to start the car. Put a new gasket n I.coils. now it runs fine, but it feels a lil weird when driving it.. like if not fixed all the way. What could be the final verdict? Is the car done?

When you check the coolant for bubbling can you do the same with checking the resovoir tank?

My car did not have much white on the oil cap. They did many tests. Turns out some oil valve seals were bad but they were not sure that was the problem but they did the work 4 of them were leaking.. They said engine was not heating very well. New thermostat fixed that. Pressure test turned up nothing. Car runs great.. Also they said drive it more Florida has so much moist air if you don't drive far and heat up the engine you will get this also. In Florida intakes bring in lots of water.

I have a 2002 rsx type s K24a2 swap but as of today I noticed slight white-ish smoke coming out of the exhaust,what could it be?

Some of these are dependent on the spot where the void is present right? Stupid question but ive had an open space in a gasket before not present with no discolored exhuast, or mixing of fluids. Only accelerating sluggishness and obvious misfires

Hello i have an audi 1.8 20vt and i changed the water pump and the thermostat and the cars temperature goes over 90 deegrees? Is the head gasket?

Why does the water come out my muffler while filling the radiator on a 2000 gmc sierra there is no water in oil and have changed out the manifold intake gasket?

the music in the background is righteous

Very informative video, thanks guys 👍

TU & subscribed. Questions: my 98 Sonoma 2.2L with 176k is having the head done (blown gasket....previously paid ($1,350) to a shop mechanic 1 month ago who ripped me off not doing anything to the warped head, amongst other faults. Now the head is being pressure tested, milled and valve job for $350 by professionals with a guarantee. I think it now wise to replace the coolant & oil pumps even though no prior indication of faults. I plan to replace the piston rings from the top. Doable? Would you suggest the timing chain as well? I ask about the chain partly because I see some kits that have the two pumps and chain together implying this is normally done together. Is the Cloyes that does away with the tensioners a better choice than OEM? I am poor and unemployed just trying to be proactive. Am I going too far? Thanx, Mark ps...I prefer to keep this truck, other than the current problems it is in perfect condition.

So is number one always present when the head gaskit is no good?

I have a 05 BMW 530i. I replaced pcv valve, 6 coil packs and plugs. intake manifold to fix smoking 10 months ago, now it's smoking again on startup and idle. no overheating. any suggestions?

Another way to test is to run the engine while having the radiator pressure gauge hooked up you will see a jumping if it is blown.

Hi. Thank you for the video. I have a 2008 Accord with 74k miles. The oil cap has a little milky oil. I checked the dipstick it's clean. I cleaned the oil cap and drove for 6 miles. I then checked the oil cap again and there was moister. I'm not losing any coolent. The car is not over heating. I never did a coolent flush on the vehicle.

Great video man, I did get a misfire in cylinder 1&6 ? And I got some white puff smoke lasts for 3-4sec upon start up while car sets for a short of time ? Is that head gasket ? Or something else ?

Milky sludge also caused by failed oil cooler aswell as oil in cooling system

My vito 113 cdi 2010 cylinder 2/4 distroud my engine. Motorblock broken. Please I need help can i do anything please or changed the engine

How do I know truly if a head gasket is blown in a 2003 Pontiac Aztec? Please help... car turns over but battery was drain due to battery? Checking battery and / or replacing

I have a 05 saab 9-3 127k miles, checked my coolant and found oil but my car doesnt overheat or loss of power. What could it be ??

I have a similar problem. Had a bad radiator leaking. Used stop leak to fix the problem for a while but the car ran hot smoking about 4 times. Had radiator replaced. And now car seems to be running fine with the occasional thin poof of smoke. On startup and while idling. Not really bad but visible. Don't know if it's a possible small head gasket fracture or one valves like you had said in another comment. I went and bought some head gasket repair liquid. But haven't put it in yet because I'm not sure if that's the problem or not. The car does not run hot now. Seems to be fine except for the thin smoke from the exhaust. Also no milky oil. Or leaks that I can see. Haven't checked spark plugs yet. Also hear a little bit of rattling under the hood when I start the car and for about 5 minutes of driving. It's a 2006 Hyundai azera V6 What do you suggest?

Kudos 👏 to you for making this video Question for you do you have a video about buying used cars the do s and dont type one

6 easy tests with 6 fancy tools.. 😂

Hi I have 01 Lexus IS 300 I’m loosing coolant from the cap of the radiator seams to have a lot of pressure but it doesn’t over heat runs good I cannot figure out please help

Have non of these faults on my car but still found coolant in the head, and white smoke out tailpipe on hot start that smells coolant. Also i stutters when accelerating?

What does coolant wet spark plug cylinder #3 mean? Valve cover or head gasket on 2003 ford expedition

its gas increse to high consumption?

Hi for step 3 you say to look for bubbles with the cap off, with car running? If you don't have a radiator cap and just an overflow tank you should start the car with the cap off and look for bubbles, right?

Okay so what's about the ordinary guy who doesn't have all these gadgets🥱

Hello there, nice video, basically i have 2013 Range (non supercharge. Since, Past two months i noticed that the coolant goes low but the engine does not heat up, this happened several times and i went to a local mechanic where i regularly go and got the radiator replaced. They did pressure test twice, no signs of leak. But still the issue persisted. I used to refill the coolant every week or so. I believe due to this the starter motor had gone bad(as i assume the engine got bit hard to turn on by itself) Now the vehicle has stopped starting. There are no sign of any leaks whatsoever. The radiator seems to go low only while running. My mechanic checked the starter motor, replaced the battery, replaced twice the fuse (on battery) yet no luck. Previously (in between this issue) i had got the oil and spark plugs changed. Now i can see some sort of milkshake type texture under the oil cap. I had re assessed with another mechanic who builds RR engines, he mentioned that this issue could be from the three coolers and not necessarily a head gasket failure. Additional information: There are no sign of over heating. I had noticed once, that from one of the AC vents, there is smoke coming. This comes only from vent and then goes. This happened about 10 times in past 2 months Current update: I just had the radiator coolant refilled up , without driving, i noticed that the coolant has gone low!.. Any expert advices will be helpful

I have c63 amg v8 biturbo 2017 and water goes in two of my pistons so much and inside of motor can u help with any idea what it is,

hi, i have a 2000 mazda 626 2.0l. my radiator recently had a crack in the gooseneck and was letting the air pressure out, after i fixed *patched* the area the next day my car wouldnt start. took sparkplugs out and notice water was mixed. Does this indicates a blown head gasket?

Can anyone explain me test number 4 please? What if i do the test after the car was running for 20 minutes or so

I inherited my Dad's 1996 5.2 Liter Dodge Ram Pickup a few years ago. It has low miles, 118,000, and there's suddenly a very frothy looking oil on the dipstick and oil cap and some water droplets also on the dipstick and a lot of moisture coming out of the tailpipe. It leaves a big puddle of water on the pavement but I don't see a lot of white smoke or steam coming out. The temp seems low actually, like it's taking forever to heat up. Any ideas what might be going on here? Thanks!!

Hey i have a 96 crown vic i have had 3 to 4 years the only problem i have is when i turn my air on it blows smoke out of it white smoke i always check oil its normal color not gueeey or nun how can i stop it from throwing white smoke when the air on

On my car the coolant in the radiator doesn't bubble until I turn off the car. But pretty sure it has a blown head gasket. The car is almost as old as I am and I'm 39.

I have a 1991 Nissan hardbody pickup. My water pump went out, and I drove to a safe location where I could call a tow-truck. Here's my question When a water pump is being replaced, would a blown head gasket be noticeable ? Thanks

99 Tahoe 350 vortek. #3 cylinder constant miss even after new plugs,wires,cap,and rotor. Checked all wires plugs etc. Head gasket or intake gasket?

any imput on steel seal. does it work???? i have a bmw 535i blowing white smoke and if it is the head gasket the numbers are ridiculous for repair. any suggestions are greatly appreciated. its got twin turbos so really hope thats not the problem😢

So if i see the milky substance swirling around in my radiator and some of it in my coolant reservoir but NOT in my engine oil filler hole does that mean it's not a blown or cracked head gasket?

Step 1: Is there smoke coming out from under your hood?

If I check my oil fill cap and there's a milky color ONLY ON THE CAP and not in the oil pan is that just condensation?

I have pressure and bubbles in my coolant reservoir but i have no goop on the caps and i have no bubbles in my radiator when the cars running is it possible my things are still blown?

What about white smoke blowing out of the exhaust pipe...would that be a blown head gasket symptom?

Had white cloud coming from my exhaust, had a cracked leaking radiator, I was loosing coolant. Got the radiator replaced & now only thin smoke for about 5 to 7 min after startup. Could I have a small head gasket fracture?

Brilliant!

If the car has a head gasket problem (low compression, misfire) but the oil does not show any signs of coolant in the engine, would it be okay to buy the car to drive after repairing the head gasket?

Hi I have a 2004 Saab 9-3 Convertible . It was leaking somewhere around the water pump so I replaced it but now when the engine gets too hot the coolant tank starts to boil and it leaks somewhere. I'm hoping it's not the head gasket.

will all theese issues apear if i have a head gasket issue

Hi, my Chevrolet Optra 2010 engine overheating. I noticed the coolant level was low and filled it up to MAX and drove around 3 days. Air conditioning was on while I was driving it, suddenly became so hot in the cabin. I stopped the car and the engine went-off on it's own. The engine couldn't be ignited there after. I took to mechanic and he said, the cause was due to engine head-gasket. He changed the head-gasket but the problem still persist, engine still overheats within a 5 minutes and gauge rises from 1/4. Mechanic said, now only engine fully has to be changed. Any suggestion please? I also noticed leakage from the coolant cap, replaced it, then seemed fine. Please share some information. I really appreciate your feedback. Thank you very much.

Guys Test Number 3 is Enough for Gasket checking if the bubbles are coming out or blowing.. Your gasket is over.. Replace it as soon as possible.. otherwise.. wait for the engine to get blown!

I just ask my buddy Superman to use his x-ray vision and I know for sure right away.

So I have been having some problems lately with overheating. My truck was going up to 260 within 5 minutes. So I parked it and we replaced the radiator, coolant temp sensor, egr valve, thermostat and bled the system numerous times and it fixed it to an extent. The gauge will show anything from 1/4-3/4 but it never goes up to 260. The heat works occasionally and the exhaust at times will blow white smoke and then it will stop

I removed my radiator cap and I saw a stream of bubbles. it after a minute. but a few minutes later it would pour out.

I have a 2000 dodge neon and I can't go ove 10- 15 mph I don't remember over heating but it's possible 1 mechanic said it was a leaking head gasket but another told me it was the catalytic converter does this sound right to you guys thank you for your response

In my car no overheating problem but once in the week when I check the oil dipstick minor milky deposit r found...! What I can do...?

What about engine power? The vehicle idles indefinitely. If you rev it, it dogs out. If you drive it, it has no pulling power on hills. It blows white vapor when first started; most of the white vapor goes away after about 5 minutes, but there is still a small amount of vapor, even 1/2 hour later.

Is there a test to see if sealant was put in.

In an old audi a4 we have cylinders 2 and 3 are misfiring and there's a coolant leak. This video makes so much sense now, goes to show how cool the internet is too

Hi today my car was boiled,when i open my engine.radiator extra tank cap was pop uped.after re fill the radiator it was runing normal condition.i was face this befor two week.will you please advise the reason?

2009 dodge caravan changed water pump thermo radiator an rad cap could it be head gasket?

What would/could be the cause of an LT1 over heating when parking? The car starts overheating fast when I'm slowly manuvering (Few feet forward, few feet back etc) into a parking space Car is fine at all other times Water pump, thermostat, and coolant are all about 1 year old I bled the system Fuses and box LOOKED ok Just put on a new ac delco rad cap Unplugged the WP to test the fans and the drivers side works but NOT the passenger side Neither the AC or the heat hasn't worked for over a year btw

I have gray smoke coming out and a constant cylinder 2 misfire. could this be caused my a blown head gasket? what do you guys think?

Where’d you get that Inter cooler?

Okay there's no milky residue in oil or on oil cap, there's no bubbles in radiator, but two spark plugs did appear to look like they had rusted a bit. There is so many other things happening with this vehicle and I was hoping that some other problem could possibly make spark plugs look that way. Car runs fine, it randomly runs hot if idling, although it doesn't go any high hot but needs some water every time. Thermostat was put on thinking that would help, I noticed the top hose running from radiator to thermostat was very hard and hot...IDK what to do

Hi there 2CarPros, I was wondering if you have time maybe to help with an issue I am having. I am running in to an issue with a 2005 Toyota Camry V8 check engine light (only 52,000 miles on my dashboard so the car is not driven a bunch over the years). The last 2 years like clockwork a year apart i get the check engine. The first time I brought it to a show I was told to go to. They said after checking with their computer I have a faulty knock sensor. So I said okay lets do what needs to be done. They charged me $700 at the time in 2020. They said when taking apart the parts they found coolant in different parts of the engine bay (i do not know car stuff I am pretty sure that is what he said). This part of the problem is how I found your video here. I am wondering too what could cause the coolant leak. They replace the sensor and a few days later the check engine light returns. Same codes on their test so they replace the sensors again (for free). A year goes by and then just before inspection time Check engine again. Go to the shop... same code. Now they do the replacement again and charge me $300 just for parts they say (do not know if that is a reasonable price). It is now a year since then and once again I have a check engine light. Also I should say my coolant is about an inch lower than it was a year ago. Just trying to ask anyone and everyone for information. It is such a hard thing to find a mechanic in NY and since I am not knowledgeable (but trying to learn) it makes this soo much harder.

Not a bad video iv been wanting to make a video on blown head gasket tests. lol hopefully I don't have to XD I hope my channel gets a big as y'alls ,keep it up!

I notice continuing shortage of water Alradietr be with foam in oil hood with no mixing in the water, or the engine oil Alradietr Is this the blown of head Gasket guide

I have a little bit of white in my oil it’s been like that for months but I don’t know if that’s bad or good cause there is no knock and the oil thankfully hasn’t got super milky

My truck warms up really fast but never goes past 210 ( the middle of the temp gauge ) it just take like only a mile of driving to warm all the way up and I do not have heat is that a bad thermostat or a blown head gasket please help?

Am I wrong in thinking that an engine with blown cylinder or ring will sound much different than if intact? Also not sure of the terms, in this specific context...there's blown cylinder, ring and head gasket. Are the first two more or less synonymous?

My car is a 3 cylinder. Has no mayo, some coolant has been used over maybe 2 or 3 months but not huge amounts. Did a compression test and cylinder 1 and 3 were 185 but cylinder 2 was 150. I can also hear an audible whistle between 3 to 4.5k revs. sounds like a exhaust leak but it is not as I've had a new one fitted and took it to the garage 3 times as I was not sure. Cylinder 2 also misfires is left at idle for 10 minutes. I've taken my car to 4 garages and one specialist who couldn't find an issue. What could be wrong?
