How To Tell If Your Head Gasket Is Blown

Reid Moore says:

I know this is totally off topic but, if Dr. McCoy on the ORIGINAL Star
Trek wasn’t a southerner, Scotty Kilmer would be a dead ringer for playing
him.. lol

asustech007 says:

Scotty, is the replacement head bolts for a 06 Pontiac grand prix 3.8 liter
engine, “torque to yield” bolts? It has cast iron heads, and from what I’ve
understood the TTY bolts stretch when they get torqued down. Would I be
screwing up if these bolts are used on this engine? According to parts
store they only list one kind of head bolt for this engine but never asked
if it had cast iron heads on it or not. The torque specs seem odd, it looks
like the specs are for aluminum heads. I can’t seem to get a definitive
answer from those I’ve called about it, so I don’t know what the deal
is…. ?

SUBSCRIBED!

adem nacakli says:

very nice thanks 

than217 says:

They told me either my head gasket was blown or that my water pump was
leaking. Would this test in the video above get a false positive for a
‘blown head gasket’ if the water pump was broken?

john imburgia says:

Scotty,

Will that work on a Cummins diesel?

asustech007 says:

Hey Scotty got those head gaskets replaced on that Grand Prix, had to take
the heads in though, one of them was warped a little so they both got
resurfaced and checked for cracks. It’s been nearly a week now and the
owner says the car has no problems. So it appears that perhaps one of those
heads were actually causing the problem…. where I thought it might have
been the head gasket? Either way, sometimes it’s hard to tell with the
problem this thing had, it was only getting very little air past that
gasket, but it doesn’t take much anyway to pump a cooling system up with
air. Thanks for your help!

than217 says:

I was having a hard time trying to get air to suck up into the tube. But
the big fans on the radiator? weren’t spinning. What would that mean.

asustech007 says:

3.8 liter engine in a 2006 Grand Prix, engine with 180,000 + miles was
overheated once from a water pump locking up. The guy who had it changed
the pump and belt but the car looses coolant slowly with no signs of leaks
in the oil or on the ground, or from the heater core. Constant bubbles come
up through the coolant reservoir after engine gets good and hot, a few
bubbles when the engine is fairly cool, and no bubbles when the engine is
cold. Wouldn’t you say he had a bad head gasket… like a very slight crack
that gets worse the hotter the engine gets?

xxkillin3mxx says:

Where can i get one of those turkey things to suck up the coolant? Didnt
understand the name


David Goodrich says:

I have a 2002 nissan sentra spec v. Changed my spark plugs then other day
and noticed oil leaked into one of the ports and was in the boot and on
plug. I also noticed oil buildup around the head when I turned car off. Im
guessing head gasket is bad? Am I right? 

GUS FUNK says:

Wtf happened at 2:13 lol

mario villa says:

He’s goofy lol

Paul Dimofte says:

FIRST PRES ILIKE AND AFTER WATCH THE VIDEO BEACUSE IM SURE IS GREAT !

John Robinson says:

Hey scotty, my transmission slips occasionally and my mechanic said I had a
blown head gasket so I paid 800 dollars to have it fixed. Does this sound
like a good estimate to you?

ipdjbt says:

Can this test be performed using the coolant expansion tank instead of the
radiator?

Chris laberty says:

Where could I grab one of these kits at?

madtownmadman says:

Does the engine have to be able to run, to perform this test? My brother
overfilled the crankcase on an 01 Ford Focus 2.0 sohc by about 1-1.5qts.
This caused the oil to foam after a few minutes of highway driving. He said
that there was a ticking sound emitting from the engine. I’m assuming that
that is when the oil pressure dropped. The engine soon afterward
overheated, and blew a cloud of smoke. Turns out the heater hose blew, and
got coolant all over the exhaust. When he got off the freeway exit, the
engine died. He said that the idiot light for the oil came on just prior to
exiting the freeway. The car was towed home, and now I’m looking it over.
The engine cranks, but won’t start. I’m thinking that the head gasket may
be blown. Your thoughts?

Holly Weimer says:

I have a 96 Celica (automatic) that accelerates very slowly. I know these
cars have a reputation for being slow, but I get passed up like I’m a snail
on the freeway. It also runs rough and loudly, and shakes a lot at a stop.
A lot of white smoke comes out of the tailpipe when I start it, but goes
away when driving. Does that sound like a head gasket issue? It has never
overheated though.

T1mbo says:

How can you tell whether it’s a cracked head/block or a blown head gasket?

KavaniLoyan says:

My car is showing signs of a blown head gasket (using a lot of coolant,
white smoke out tail pipes that smells like coolant) so I did this test and
it didn’t yield any results (test liquid didn’t change color at all).

Mladen Milić says:

After replacing head gasket , engine did nost sound right , and rubber
exaust mounts caught on fire . Also , I noticed that spark plugs are sooty
. I think that fuel injector (car is 1.6 Opel Vectra A , it hah something
carb looking with one injector) is puting too much fuel , and mechanic says
that I need new cylinder head . 

alex prinzo says:

I love how happy you sounded when the car revealed it was blown haha! Love
your vids man, very helpful!

squibblesthehusky says:

as of today my new head gasket went out, is it possibly warped head?

serius tn says:

Thank u scotty kilmer I have a wolksvagen touereg 6cylinders gasoline 2004
gasket blown the water of radiator evaporated with the exaust smoke…

Joe Shook says:

Thank you Scotty very very much, i’m amazed cause based on watching your
videos, I thought that was perhaps going to be the thing to do.

Tim Chaplin says:

My ford ranger 2.3 94′ has blown head gasket. my catalytic converter is bad
so im gonna also swap the entire exhaust system. quick question: the air
intake has alot of egr system…the air cleaner has connection to the
exhaust. i want to install a cold air intake and a new exhaust system, do
you think i could do that without the egr connections? im sure your
familiar with the 94′ 2.3 and all its egr connections. I am worried about
the installing all that stuff neglecting the egr system and confusing my
computer? perhaps i can bypass the egr electrical system? any suggestions
and help would be greatly apprectiated sir.

Dylan Ewing says:

Hey Scotty, what if my vehicle doesn’t have a radiator cap? Can I do this
test with the coolant reservoir since I don’t have a radiator cap?

Travis Verdin says:

+Scotty Kilmer I have a 2007 dodge charger 2.7 and it over heated then it
started leaking from the water outlet,i had that changed and now it rides
rough and it blows out white clouds from the exhaust,the car idles but when
you press on the gas it revs then shuts off,what could be the
problem,radiator,water pump,head gasket?

Jahshawn Carr says:

has he ever locked himself in the trunk?

spaclqd says:

no doubt your auto smart, but why the 2 second wait after your video cuts

Eric Easton says:

Haha, this guy right here!

Dylan Johnson says:

1997 Mitsubishi eclipse, only starts smoking after about 30 minutes of
driving. Its not constant smoke, only when I accelerate. It goes away after
I get into 2nd or 3rd gear. Any ideas on what it is? Thanks 

Charles K. Gearlds says:

scotty thx for all ur help just recently my son was driving from his
description sounded like alternator or belt broke however I went to
investigate and it started fine no batt light for first few mins idles
perfect but when put in drive it sputter worse than any car I ever saw ??
is this a cam sensor?

OlBlueshound says:

Cool, good little product I reckon, you can also tell if a head gaskets
gone by smelling the coolant with the radiator cap off, it smell like
“exhaust” gases mixed with coolant! Lol, also, if you rev the motor harder
maybe up to just below the red line, under load is best, it usually spits
the coolant out big time to the over flow tank, but won’t suck back on cool
down like it should. It’s hard to tell the between a blown head gasket, and
a cracked head though!

brian foley says:

smoke from exhaust gas is a clue

Nate LeDuc says:

I don’t think this is 100%. A cracked block would do the same. 

Anthony Canto says:

SCOTTY! I just drove home and check engine light came on while going 85 on
freeway. WHite smoke coming from tailpipe as i drive. engine overheats.

john simons says:

I filled the radiator with oil but nothing is happening

sanBastian123 says:

HI Scotty, I had an overheating engine this weekend. The cap on overflow
jug opened. But after pouring coolant and closing jub, a creamy rusty
orange yellow gunk came out on the radiator . No oil but rusty butter.
Is this a bad sign? I never had to top my coolant. The car is old over
228 K miles. Anything to watch over?
