I've never tried the Blue Devil branded stuff, but I had success with K-Seal head gasket repair on a beater 2003 Hyundai Elantra a couple years back. It had the typical white cloud out the exhaust, the oil looked like a chocolate milkshake, pulled the spark plugs out of it and number 3 was soaked and the gap was completely closed with goo. It was a car I paid 1500 bucks for and used as a winter beater for 7 years, it wasn't worth my time or money to fix it the correct way, I figured I'd give the $30 fix a try before hauling the car in for scrap. I drove it back and forth to work for few days afterwards, put like 75 miles on it and it stopped smoking and the misfire cleared up. I gave the car to my 16 year old nephew, told him it would probably get him around for awhile as he saved up for something nicer, that was 3 years ago and he's still driving the thing... It's survived all the standard issue neglect and complete lack of maintenance that comes along with being a teenage boys first car, so I imagine it'd be fine for most normal functioning adults.

This is how all how to videos should be made. You didnt over talk which is frustrating. Each step was easy to fallow. Thank you. O!And love the wife's reaction. Lol😊

I was having the same problem with my f150 . Hydro locking, the same exact thing as yours, and I followed your advice and problem solved, 9 months and still going at 394,000 miles, thank you 😊👍👍👍

I was so glad you told us NOT to eat the milkshake. I was thinking... Ummm... I sure would like to eat the Milkshake but then Herb said DON"T. So I was like Okay... I won't eat the milkshake.😁

The sarcasm is STRONG with this one, love it👍👍👍👍

Great step by step video. Best part was the three month follow-up on how well it was holding up.

I used this stuff in my V10 Excursion 10 years ago, still runs perfect to this day.

I definitely have to subscribe to this guy. This was the most entertaining Mechanic video I’ve seen other than Scotty Kilmer! This guy is hilarious. All his jokes were executed with perfect timing.

I've done oil changes on a few of those vans and the engines are packed in there! Lot of fun too when they'd just came off the highway, not only messy but 'warmm'

"DON'T DRINK THE BEER." Kudos to the wifey for her support!!!

I have been using SuperTech synthetic oil for years. It’s great oil. I used the pour and go Blue Devil in my truck because my head gasket leak wasn’t as bad as yours. I had to do a couple idling runs like you did to get it to seal.

That's really interesting about the inert silica molecules being activated by the combustion gasses, i always wondered how this stuff sealed without clogging, makes sense now.

As soon as I saw the first attempt fail I knew it wasnt getting hot enough. I had this experience a few years back but my head gasket failure was too much for the stop leak to seal. Glad it worked out for you. Here is to another 115k miles more.

Water level changes cause of the air being purged as the engine runs there's pockets that are in the block that it can take awhile for it to all purge out

Appreciate the thorough video. Helpful and funny. Well done!

Hey, Herb. I have a question. You mentioned to keep the sealant in the car for awhile to insure everything works out....My question to you is, did you still have the Thermostat taken off? Or when you took it for a drive, did you put the thermostat back on while the blue devil was in the engine?

I love your humor, thanks for doing these videos.

Glad it worked for ya, head gasket job on those could total the vehicle

This Stuff truly works guys. I had a blown head gasket in a 2004 Nissan maxima. I put it in and didn't flush it and thought that it didn't work. I did notice a difference but wasn't sure. Someone posted that this stuff needs a flash point to truly hardened and worked. They also said to for better results to us blue devil flush and use distilled water. After doing this I drove my car a little high than normal hwy speeds and got the motor hot but not crack the heads hot but just a high temperature like water boiling temp. Once i did that and stop and let the car sit and cool. Afterwards OMG did it work and with a rock solid seal. Not everyone will have to do it this way but it worked for me. Flushing the engine first seem to help once i did that and started over.. I have tested it and yess it totally fix. Air conditioner runs with no engine over heating.

This was hilarious yet educational. Bravo! Well done! 👏🏽That sound when you opened the first distilled water caught me by surprise and had me in stitches 😂. Then continued to snowball into pure comedy

Thanks for the warnings I was about to drink all my engine's fluids.

Love the safety advice lol. Although i followed all this advice and then accidentally forgot to put the car in park while working on it and flattened a buddy.

Your Goofy humor is right up my alley. I'm the same way you're just on a higher level than me. You actually had me going on the not mixing different brand distilled water. I was like wait, what?! That's the same thing. 😂

Wow your soo complete explained everything! Great content!! 🙏

Very informative and easy to follow tutorial. Giving Chrisfix a run for his money. Love the humor. Was waiting for a Kelis joke as soon as you mentioned milkshake and you didn’t disappoint.

The milkshake (oil+antifreeze) can also be checked for on the underside of the oil cap

Excellent video. Made my decision solid on this product. Thank you!

Another great video herb😎👍

I’m watching this video to do it myself. Only problem I’ll have is that it’s 5 degrees outside here 😢. Great job man THANKS

I was just thinking I have not seen a bunker video for a while, then this video shows up. Not the video I really wanted, but better than nothing :-)

I didn't try but am feeling so better now that I saw your video and I will do as u say probably with a different product because here in my country we don't get as we like ,so as soon as I try your fix I will hit u up with some information peace bro, and I hope my milk shake don't bring no boys to my yard 😂😂😂love that part cheers.

Thank you for the good video. I have the same problem right now.

Do you think it's a good idea to bypass the heater core before using this stuff?

Like your video comparing too some other ones I’m going to try it on mine today

I really like your style, my channel is growing but you really take time in your video editing and I dig it 😉

Worked for 2009 Chevy Equinox. You MUST remove the thermostat! And you must pour the whole bottle directly into the thermostat housing NOT the reservoir. It will work! You must be careful. If it doesn't work the first go at a cold start do it again and again. Took me 3 full cold starts to fully seal the leak! Yes took me nearly 2 days of cold starts for it to work but after the 3rd start the exhaust finally came out clean and the car never overheated again!

well done! enjoyed the humor. Curious to understand why/how this is preferred to the POUR N GO product. Thoughts?

I don't miss working on vans. That Milkshake does not bring all the boys to the yard.

Thanks for cooking video. I'v got hungry while watching this so I started eating and drinking.

Good luck with it mate - I hate car issues, they make me cry!

"Try to keep your drink atleast 12 inches away from your deadly chemicals." Hahaha that had me rolling for a while. I need that Fiesta Agua Amigo hahajahha you are hilarious bro. 😅😂

Excellent instructional video ! Excellent step by step lessons Herb.

I gotta 01 Mitsubishi mirage wit a gasket problem. Milkshake gunk n all.. My only means of transportation, I'm glad 2 see dat dis stuff really wrks. Wonder hw lng does dis stuff really keeps a kar n wrkn condition.

Pouring the blue devil(not the flush one) can you do it with anti freeze? Or does it have to be water specifically?

I subscribe after he went out and bought new tools to make himself feel better love it me too sounds like a great idea

Yes!!!! Shopping to feel better. My motto too!

Hey, when does the thermostat get put back into the block? I’m getting ready to use this stuff on my Jeep and I think that after running it for a day or so I can drain off a couple gallons, replace the thermostat and refill with the Blue Devil mix I drained off. I assume I will get higher temperatures that way. Does this make sense? Or will this cause this stuff to try and do it’s thing in the hotter block and thermostat thereby gumming up everything? So I want to know when it is best to install the thermostat. I’m wondering if it is best to do the thermostat after draining and filling with coolant. My understanding (?) is that you want to end up with a mix of Blue Devil and antifreeze to run on until you get to time for your next flush or at least until you forget that stuff is in there.

It was good that your thermostat was ok when you left the blue mixture in the system.

Did u change the oil once or twice after the milk shake? Any updates since its been a year on how the sealer is holding up?

Awesome that stuff also fixed your brakes

I love it!!!! Very good video!!!!

Pulling the passenger side kick panel and seat makes it easy to work on the engine from the inside and remove the doghouse

So it's another stop product like the bad radiator stop that causes clogging over time. Do the makers say it permanent fix?

did you put back the thermostat after flushing or you run it without thermostat?

Luckily I have the 98 Ford E250 cargo van with the 4.2 l V6 Essex engine so any engine work that needs done I can do it from the inside of the van with the doghouse out I've done intake gaskets and intake passage cleaning and I deleted the PCV so now the crank case is vented to air and EVAP lines are all deleted too my van is emissions exempt in VA since it's 25 years old but yea I been trying to get it to run as smoothly and perfect as possible

I came back here just to make this comment and say Blue Devil works. I'm in southern Ontario, Canada and perhaps estimates will vary depending on geographic location. My check engine light came on and I had a code for a cylinder misfire in cylinder #4. After replacing coil, spark plug and fuel injector the check engine light was still coming on. I took my van to the Ford dealer. I have a 2010 Ford E250 4.6L with 199,000km on the odometer. They confirm it's got a blown head gasket and quoted $6,534.00 to fully repair. I followed the directions for Blue Devil exactly. I bought the Blue Devil radiator flush and followed that also. My van needed 2 bottles of Blue Devil and 2 bottles of their radiator flush based on its capacity and just followed everything. On the second day after completing the process my check engine light went off by itself (did not code clear with the code reader) and its been off ever since. I have since drove the van about 1000kms. It works. So if you have a blown head gasket you should use this and I can only attest to it working if you follow it 100%. But it seems like many people have success with just pouring it and forgetting it.

Your wife looks very happy and extremely excited 😅😅😅😅

Fuel line hose for the radiator overflow ? My coolant reservoir came with the hose its a car quest tank i think the previous tank was cracked and system wouldn't keep 16 psi

Question: When did you put the thermostat back in?

Hi Herb- enjoyed your video. I had the same issue with a 93 Toyota Corolla. I don't want to break your heart or spoil your expectations. Blue Devil/Bars Stop Leak/ and other sealers usually last (if you are lucky) around a year. What happens is that your head gasket will simply start leaking in another area. I suggest you use the "Pour n' Go" by Blue Devil after a year if it shows loss or not. Unfortunately, sealers do "not get along" with antifreeze and your problem will resurface at any given time. Sealers are a "Band-Aid" to head gasket repairs but I can see your point in your vehicle where the motor must be removed. As far as my Toyota was concerned, I had a severe head gasket leak and I used the "Bars Block Seal" which required the same procedure as yours did with the sealing. I was able to drive the vehicle for another three years by adding sealers annually before I retired the vehicle at 280 thousand miles.

How is this holding up? How long had ut been? And how many miles?

Do you leave the distill water after treatment?

How long after you use it can you tell if it worked??? how long will it smoke?

I cracked up when you were inspecting the spark plug. How’s it holding up?

My ODB2 port is in my glowbox on the passenger side. So NO not always on the driver side. Good video non the less.

wow thats freakin awesome.... gonna try this in my eclipse maybe

Thank you for this. 🛠️✨

Very helpful video

How long did you wait to put your thermostat back in?

I have that scanner and the think diag Bluetooth one too

I got 20,000 miles out of my first treatment on a tundra. Going for number 2, with the method of leaving it in for a day or 2 before draining as well. I let it idle this time for an hour, then took it out for a few runs where i gunned it a bit on some stretches and no more steam. All in all an hour and 50 minutes, about 20 minutes was driving. Well see how it goes the next fews days..

So it’s been a year now. Sounds like it’s still working? How many miles have you put on it?

We use to use Liquid glass ( always worked ) worked so well you have trouble removing the head !

I'm thankful for the PSA's, I would've drank that milkshake and vape'd that exhaust juice

Can't wait until u do the bunker again

good job man🎉

Just curious if you've ever re-checked your thermostat/spark plug/s after the 3 month period or lately? Just to see if any build up of BD's resin had formed.

Super tech oil is actually very good oil they tested it with a bunch of other oils on the farm channel I can't remember the whole name of the channel but super tech did very good against the other oils I use it in my vehicles for many years keeps my engine clean runs great.

Band aid in can fix that is a temp fix.Lot of times it will wash out the piston rings too.Will have a miss with a headgasket problem

And follow up did he put in a “new” thermostat when/if he put it back in?? I assume he would as they aren’t expensive.

Did you ever put the new thermostat I didn’t see you do it lol

So can i ask why water? I have a 09 bmw and afraid to use water. Theyre finicky im told and inly the euro mix can go in. But i don t wanna waste it either because if i had money to burn id hire someone to do the proper fix

thanks man great video,

comedy is amazing, especially the loose hose

Thank God you saved the day 😊

Loved your video. You are funny!

I'm getting commercial breaks every 90 seconds. Gonna bow out on this video, but thank you again for your videos. I always enjoy them.

very informative video...thnx...😃👍

What is Chanel locks or do you mean channel locks

I subscribed cause you’re FUNNY af😂

My 2010 Prius was just diagnosed with a leaky head Gasket after I brought it in, suspecting cylinder 2 & 4 were misfiring. I've never noticed Coolant disappearing and the car has never overheated, also my oil looks fine and there is no white smoke out of the tailpipe. Does this still sound like a head gasket? I did go get Blue Devil today to start this process but I am NO mechanic and I don't have the tools or ramps to work on/under my own engine.

I haven't laughed this hard in awhile. Shopping for a garden hose nozzle to replace the wife now. 🤣👍

Subscribed good shiit man

Gracias Amigo.

ty, and the comedy is great

Very informative and funny. Although the oil looked more like a bad bathroom trip from some Mexican food.

24:03 If the leak is really really bad, you could try running it to seal with the offending cylinder spark plug out.

Its blues clues and dora the engine explorer can you say fouled plug or needs a new engine

SuperTech isn't bad stuff, it's made by the same people who make Kirkland Signature, Amazon Basics, and Meijer brand oils (possibly more too.) I believe the manufacturer is Warren Distribution, you should be able to find that on the back of the bottle's label somewhere.

Any updates? Is it still working?
