Hey guys, you can buy a kit for around $50 that will do the job of this gas analyzer that I am using in this video. Here is the link www.jbtoolsales.com/uview-560000-combustion-leak-detector-kit#oid=1014_1 and here is a video of me using it kzfaq.info?o=U&video_id=k5VVcNKAK6U

my suggestion: get the one with the hand pump bulb on it instead of the vacuum hose [the one you listsed has the vacuum hose and requires it to be hooked up to a vacuum source, ie, throttle body]. its IMO a better option. that way you dont have to worry about unhooking anything or finding a suitable vacuum location. just pump the bulb and go. napa usually carries it, or u can order it off amazon. its the same price. they also usually carry the fluid for about 7$. it has a shelf life.

Hi, I’m Rey Z. I had the same thing done to my 70 Impala last month I have a 350 engine. and the reading for the HC was 15. The smog guy and the mechanic said I had a blown head gasket. But when I took off the intake my intake gasket was blown.. because I had no water in my oil. on the valves. And no bubbles in my new radiator. Gasses was leaking throw my intake. I cleaned up the intake and replaced the old gasket with a new Fel-Pro gasket. Now my car doesn’t over heat and it runs beautifully.😇🙏🏽👍

@Jerkwaad 9 жыл бұрын

CORRECTION TO THE VIDEO: The fact that there's milky color on the cap/dipstick does not determine whether you have a bad HG or not, and here's why: For every burnt unit of gasoline, the largest byproduct is water. Now some of that water gets by the piston rings and enters the crank case. This escaping of burnt gas is referred to as Blow-by. Now disregarding unburnt fuel and Nitrous Oxides, this gas is mainly CO2 and water. Mostly water even. And since it has just been burnt, it is still warm. Thus is a fair quantity of water vapor present in the crank case, and water vapor likes to condensate on the closest cold area. In many cases (depending upon engine design) the oil cap and the top of the dipstick are the coolest part of a warmed-up engine. And that's how and why you get the condensation on the dipstick/oil cap.

@ScannerDanner 9 жыл бұрын

A faulty egr COOLER on the latest design EGR valves can lead to near identical symptoms as a failed head gasket.The cooler goes porous leading to-coolant loss,white exhaust smoke and occassionally exhaust gas in the coolant when exhaust back pressure is higher than coolant pressure.This is a common occurance on the latest VW TDI engines and I've heard of a few garages getting caught out diagnosing the problem as a failed head gasket.

I wouldn't argue with that I am just simply showing a faster more accurate way to identify a leaking head gasket. some early head gasket failures will not show up with a leak down tester. they tend to leak only with combustion pressures and air pressure in the cylinder is not high enough to show the problem.

If a head gasket is blown you will usually get a bunch of foam forming in the gas bottle. If you see that it means there is combustion gas pressurizing the cooling system. If you leave the cap off a while the mass of foam will grow larger and eventually will start coming out the top of the bottle. Then next you can start taking the head(s) off.

@joevignolor4u949 6 жыл бұрын

Ford calls it a "gas bottle" because it collects evaporated, gasified coolant in a closed liquid system. Some people still refer to them as "overflow tanks" or "coolant reservoirs" but in these newer closed systems that terminology isn't as accurate as calling them "gas bottles". Calling other people names such as "retarded" is ignorant. If you disagree with someone that's fine but name calling and insults are not necessary.

Will it detect a slow leaking head gasket? I bought my Ibiza TDI new and it lost coolant since the beginning (coolant got blown out through the coolant reservoir). I drove more than 100.000 miles with it. The garage couldn't detect it with a pressure meter. The problem only got worse throughout time and I needed to add coolant consistently. The head gasket is replaced now. The guy from the machine shop said the engine was in excellent condition, probably because of the fact I always followed the maintenance schedule.

@joevignolor4u949 7 жыл бұрын

Obviously cooling system problems can be reduced by regular cooling system flushes and coolant replacement. But also my father always used to advocate running these systems unpressurized. Over the years I've found that doing so does not cause these cooling systems to boil over, even in very hot weather with the A/C on. Meanwhile, running the system unpressurized puts less stress on the head gaskets, hoses, radiator, water pump seals, bypass tube, heater core and so forth. I have a small hole that I purposely drilled in the top of the expansion tank in my vehicle to keep the cooling system unpressurized. The bottom line is that I never seem to have the same types of cooling system problems with my vehicles as many other people do. Specifically, I've never had a blown head gasket.

Mine has been running perfect for 70k miles now as i use the car for uber & lyft, Only cost me about $120 total.

more and more modern engines have direct firing fuel injectors, where the injector nose is in the combustion chamber & is cooled by coolant fluid passing through the head. If the injector seals leak, combustion gases can enter the coolant. With such engines, many times a head is changed mistakenly since the symptoms are exactly the same as a cracked head. Always read the workshop manual thoroughly. most injector/combustion chamber seals are of copper and as cheap as $4 each

I researched 2 simpler methods to tell if you have a leaking head gasket: 1) Get a spill-free funnel. Attach to top of radiator and overfill with coolant. Run the engine to normal temperature until fans turn on for 2-3 cycles. Look for bubbles. Bubbles at the beginning are normal but after the 2nd fan cycle means you got combustion gas leaking in your coolant. 2) Fill radiator up to base of the neck. W/ rad cap off: If when engine is turned on the coolant spouts/shoots= leak. Comment if u heard2

Hello friends, I have a question about cooling problems, I have a land rover defender td5 , 1999 year. I have a cooling problem, few days ago, I check my temperature indicator , and my car was in a high temperature in red . when I checked the coolant I found the that the car have no coolant, so I refuel the tank of coolant again and I never loose the coolant until today. So if the block gasket is bad and I make the pressure test of HC, what is the measure with bad gasket and what is the measure with nice gasket. Thank for your answer

Question: Is there such a thing as a partially blown head gasket? I have a Lincoln LS that head repeat ignition coil failure and replacement. The car much later on,overheated repeatedly and cracked the overflow bottle. It happened 3 times in a row, the first one lasted 8yrs,the second 4months, and I'm on the 3rd one now. I'm thinking poor sealing causing engine pressure to blow weakest pt,the overflow bottle. is this possible? No milkiness in oil,or white exhaust smoke.

+Review guy No sounds like a problem waiting to happen. Find it sooner than later. You mite save yourself from costly repairs down the road You can also use a blown head gasket test.
