I thought i blew my headgasket a couple of weeks ago, but i recently did a compression test and i got 180 180 180 190. This is on a 1994 Ls motor with a drag manifold + intercooler with a t3.t04 turbo, tial wastegate and voretch fmu, stock injectors. I just got a s-afc then white smoke was coming out. Could the headgasket still be blown with these numbers?

I'm going to get bigger injectors and a hondata after this problem is solved.

Any suggestions?

Plus any one in florida wanna help me out?

 

if your headgasket is blown, you usually would get a lower comp number. try to do a leakdown test first to isolate everything out of the longblock area.

how's your idle ?

Check your oil make sure its not a creamy color.

Also, this may sound stupid, but check your radiator. Make sure it has no holes, back my my old civic was boosted, one day i was driving down the road and white smoke started blowing out teh back, thought i blew a headgasket but it turned out i had a small hole in my radiator, it was blowing coolant on my downpipe and making white smoke.

 

white smoke and good compression?

does your turbo have coolant lines hooked up? if so that could be the problem. coolant going past the turbo seals and being blown into the combustion chamber and burned

My idle is fine but i see the white smoke coming outta my exhaust.

btw flamenco how do i perform the leakdown? got a guide to what i exactly need?

Also the oil is coming out the same no creamy color.

Everytime i'd hit the gas more white smoke would come out.

thanks for the replies guys!

 

too much oil

 

I am also assuming that the turbo seals might have gone bad. Check the turbo for oil leak going into the charge pipes.

 

so you think it's too much oil?


how can i fix that? what could be the problem?

umm......umm........

dran plug?

 

maybe ringlands

 

I only put 4 quarts of oil. hmmm i'm confused about that part.


How can i check if it's the ringlands?

 

on my single cam i blew my headgasket and the comp. test was fine. Do a leakdown test that will help a lot more.

How do i do a leakdown test? Do you have a link to a guide that shows step by step?

 

you need to get a leakdown test kit. Or you could take it to any mechanics shop and they will probably do it for you for some $$ on the side.

There is no way for coolant to get into the turbo's exhaust. The coolant passages are seperate. No seals. It's probably oil burning..!
Is your return KINKED!?

Good luck...

I'm thinking it's probably the return line, could it be the feed line as well?

i'm going to take pics of my set up and let you guys judge it.

 

did you change the oil when you put in your turbo?? make sure you dont put more than 3 quarts of oil. one time i alittle too much oil in i was smoking like **** man.

 

i had a leaky headgasket(was overheating) and my compression test numbers were close to perfect. my oil was not milky, and there was no oil in my reservoir. i changed the headgasket and headstuds and no more overheating.

Those are my votes... to differentiate bewteen them, you have to have the car completely cold. If ringlands, the car likes to smoke when under boost even when cold.... if turbine seal, it takes 2-3 minutes for the exhaust pipe to heat up enough to start burning off the oil in the exhaust. Usually smokes most noticeably at idle.

I doubt this is a coolant problem, as antifreeze vapor smells sweet, but I'm not ruling out a blown headgasket entirely.


If oil return is kinked it will cause oil to pass your turbine seal, and act as mentioned above.

 

The thing is the car isn't overheating,

 

When i first blew my ringlands, compression #s were pretty solid. I had like 190, 200, 190, 210, and 200. They were off by more than the allowed amount, but it was still high.
2 months later, after driving NA, I was down to under 50 in every cylinder. Just keep an eye on it.
Id venture to say its oil/turbo related though.

 

How would he know for sure if the turbine seals are done??

Yeah how would i know if it's the turbo seals?

You could always take your turbo off and put a header on and see if it still smokes.

 

thats what i did
