ok
i got my car back from the shop and on the way home i over heated

i pulled over
let it cool down
and made it home ok (no trafic + drove fast = stayed cool

i get up the next day and take it to a local mechanic
10 feet before i get there
my car start smoking like a ****

under the hood and from the exhaust

now yesterday to me and my friends the smoke looked white
today it looks blue
but doesnt smell like burnt oil

i checked the radiator cap and it looked like it has some oily looking stuff in there

how can i be 100% certian its the head gasket

is there any way to be sure?

wilsel

Leakdown test, or pressure test

redline201

where can i have this done???

Archidictus

You can buy a pressure testing gauge from autozone for like $20 and do the leakdown test yourself. It's not hard at all.

redline201

same as compression test???

when i do it
how do i tell if my head gasket is bad

what will the numbers look like

Caveman74

is there coolant in the oil? That is a sign of headgasket

here's an easy way my buddy's and i use to test leaks. if compression is low, pour about a teaspoon of oil in that cylinder and test it again, if the compression comes back up...your rings are bad, if it doesn't come back up or only a few psi's...your headgasket is bad.

what did the mechanic say?

ok i just took the screen off my turbo (ghetto for not having a filter)
and there is oil in there
the wheel spins freely
but there is definatly oil in there

what does this mean ????

redline201

anyone???

redline201

ok now this is weird
i just did a compression test and all the numbers were about 220

what do you guys think

Evs-One

you blew your head gasket most likely.

The compression test would only be effected by the head gasket if the head gasket blew around the cylinders.

It may have blew by an oil alley or a coolant alley.

If you oveheated and smoke poured out the exhaust and the engine, I wouldn't doubt it. You might have warped the head also. If you're pretty mechanical, should only take about an hour to pull the head

redline201

so it still may be the head gasket?

i was thinking my turbo seals are shot

im scared to pull the head and have to pay like 500 for the parts and labor

and find out its somthing else

i have no coolant in my oil

but a little in my radiator

Evs-One

if you fire it up, can you see where it's leaking??? Does it leak out of the engine, or only smoking out the exhaust now???

redline201

i looks like its coming from all over

this is so confusing me

maybe ill take of the turbo manifold to see if the motor is smokeing or the turbo is smoking

DX Hybridizer

Sounds like you my friend have a bad head gasket or intake manifold gasket. Oil in the radator or milky looking oil means your mixing oil and anti freeze. And given you are running a turbo makes it all the more probably of the head gasket.

White smoke is a good indicator as well. It should smell sweet as well I don't recommend smelling it. Your car has become a large bug killer. Not really the shops fault if you hate issues before that you may not have known about without the excess heat. But it's a head gasket pretty dead on sure.

i never blamed the shop

so even though my compression test went well
it still may be a leaky gasket???

ive only been in boost maybe 3 times

Pho Real

Why an intake manifold gasket?

redline201

ttt
any one else
school starts tomorrow

should i change the head gasket ?

R6Elmo

sounds like the headgasket to me. You have all the classic signs. Probally not the turbo as that won't cause coolant and oil to mix.

it sounds like you are hopeing it's a turbo seal over a head gasket? both cost almost the same to fix and the same amount of time.

South Bay Surfer

blue smoke=burning oil
white smoke=burning water/coolant
black smoke=unburned fuel

yeah i wouldn't recommend smelling the exhuast fumes. although i used to do it. often u can detect the unmistakeable smell of burnt oil or even coolant (sweet smell).
