How To Tell If Your Head Gasket Is Blown




What do you think about this video?

43mackmobile: Hey Scotty I usually remove the fan belt so the water pump is not turning and just look for bubbles in the radiator which indicates a blown gasket by the cylinder pressure leaking into the cooling system or excessive water vapor from the exhaust which shows up initially on startup.

William Ross: Isn't it possible that the gasket is blown on the side away from the engine? In which case rather than the oil or gas escaping into the cooling system it would escape out of the engine onto the floor in which case this device would not report it?

‫غريب الدار‬‎: ادبجحك بك شبعت ابلسوت. هت فونا غيج غروك ارحيم ارهيس فون عجب هيك خارين ريوض ارتوض باستكون خارين.

San Andres R: I have learn a lot from you Scott thank you

Darth Enigma: This guy is rowdy af xD

Mason Jones: Mitsubishi Montero 2000 i dont See Any white smoke are coffe like oil but it does over heat coolant boils over

moneyhungryyt: Is it still an accurate reading if you do it on a car that has a overflow I can't get to my radiator so I have to do it at the overflow bottle.

Daniel Liston: Would Autozone have this kit to loan me. I suspect I may have a blown head gasket on my Mazda, but I'd like to check before I go tearing the engine apart or spend money on a sealant.

mario agostini: Scotty brother....!!!!!  please tell me something... "can you tell from exhaust gas a head gasket leak"?I don't mind to take the car for an eTest since it is cheaper than take it to a mechanic.... Why I am so curious? .. I got V6 Ford Tempo ( a great car) and since last week I use high octane gasoline white steam like smoke comes out from exhaust when other cars not... I am not sure if it is the 92 octane gas that cause it or I got a leak in the gasket?

Sebz: Hey +Scotty Kilmer! I have a Audi A4 B5 1.9tdi with a expansion tank, so how do i use the "Combustion Leak Tester"? Do i put it in the expansion tank? Thx!

Jeff Fuehr: i don't know why everybody is so quick to think that it's always a blown head gasket. because it seems to me, that the cylinder block or the head would crack, before the factory head gasket would. what do you think?

Nick Laterza: Great way to to For a blown Head Gasket SCOTTY !!

LOVE YOUR VIDEOS!! GREAT DIAGNOSTICS!!

ben lawton: the day when the back latch door falls off that truck XD

Tyler L: Coolant bubbling after long drives, the head gasket was already replaced any clue what else it can be? (American GM 3.4)

paul bundi: great stuff scotty..this one you came though

Dcc357: I'd hate to see the day a head gasket blows on one of our vehicles.

010101Gaming: Well if your spark plugs are foul, if you smell coolant while driving....you need to replace head gasket.

Cody Davis: how much does this little kit cost. i really want a grand am gt coupe but I guess the 3.4 is notorious for blowing head gaskets. never had this problem with the one my dad had a while back, but with my luck I would have the notorious grand am motor killer

eatmyskids: This is a good idea, but it also could be a cracked block or head. I have some that were so bad, I didn't need any thing this fancy. The engine wasn't even warm and the coolant was bubbling like a caldron. That's bad, actually that one was a cracked block. I didn't know it until I pulled the head, didn't even need Magnaflux it was that bad

leaf smoker: i know i have valve cover leaks but not sure if i have head gasket leak. if i buy this kit will it turn orange/ yellow if head gasket is good but the valve cover is bad? thanks,marc
