blown head gasket? or something else?

[shadoof77]

ok so I have a mess load of white smoke. I thought it was the turbo, but when I pulled off the intake and the exhaust manifold, the turbo spun fine. So my next question is it the head gasket? I checked the oil and no signs of a milky white color... if I blew a head gasket would it be only white smoke? Or is it something else. Also, I noticed a mess load of oil coming out the exhaust manifold. Is it possible to have blown a head gasket where I would have both a coolant and oil leak but not have it mixed?

This happened as I was pulling through first gear, and after I noticed something wasn't right I had to drive it down the road a little bit to put it in a parking spot. As I was driving down the road it wouldn't stay running unless I kept giving it gas. As if it wasn't getting air. Would this also be part of a blown head gasket? When I was driving it roughly 200 feet, how much damage could that have done?

I'm also looking for a step-by-step removal guide as I will be attempting to do this myself. I'm up for the challenge.

Thanks in advance!

It also might be your valves

nothing that quite answers my questions

^^^ I know what you mean when I first started on this forum every one always told me to search but I wouldnt always find the answer I needed. But if you checked your turbo and it was fine, then you checked your oil and it wasnt milky then it could be your valve seals.

thats a good point. i'm probably going to do the tear down tomorrow.

In my experience, valve seals don't usually catastrophically fail...they wear over time, unless they are just brittle and crack. I think it is more likely the head gasket, especially given your other symptoms. What kind of temperatures were you seeing when it happened?

You said "white" smoke... is it from coolant or oil? I would suggest doing a leak-down test to give you some more insight into exactly what is going on with the head and head gasket.

The turbo seals could still be bad, and that could be why its burning white smoke. If the valve guide seals where bad it would smoke blue when you started it in the morning. You have to do a compression test and a leakdown test to know what is going on.

 

[shadoof77]

yea its completely white smoke. temperatures were normal. it was more like started the car up, let it run for about 3 mins then took it for a drive. by the time I went to take off through first gear it had to be atleast! 10 mins. and it was pretty warmed up. and I can't start the car, as I already disconnected the intake from the turbo and the turbo is disconnected. but like I said it was like a lot of white smoke. and I mean a lot!

 

[awdtalon21]

Are you on the stock turbo?

 

[shadoof77]

evo 3 turbo

 

[awdtalon21]

Well like i said before i think you should do a compression and leakdown test before you go any further.

 

[90on35psi]

You've got white smoke, oil in the exhaust manifold, and the car wouldn't stay running without a little help. Sounds to me your felt head gasket finally had enough. You can do compression and leakdown tests but all signs point to head gasket.

 

[shadoof77]

ok then thats what i'm going to shoot for. the head gasket.

 

[Dizorganizer]

if you have milky oil then that means that the oil has coolant in it and its the headgasket.

 

[BogusSVO]

sounds like a combustion to water blown head gasket. (this type of blown HG will not mix water in the oil)

you will need to check the head for warp.

good chance the head is warped.

you will want to have the head checked for cracks due to over heating.

if the head is not cracked, but warped, the head will need to be milled
DO NOT LET THE SHOP BELT SURFACE YOUR HEAD!!!

before the head is milled you may want to do this oil port mod...
http://www.dsmtuners.com/forums/newbie-forum/341028-4g63t-head-oil-port-mod.html

the head gasket surface should look about like this, with either a MLS or composite HG
http://www.dsmtuners.com/forums/new...face-4g63t-cylinder-head-mls-head-gasket.html

and the thickness of the head needs to be measured, at 4 points on the head.
New head thickness is 5.200 and AREA min spec is 5.185 any thinner than this, you should run a thicker HG

I would not assume it is the head gasket until you at least do a compression test. That should have been the first thing you did before you pulled your turbo and intake off. Could very well be something else. I am leaning toward rings, or ring lands. Same thing that you are trying to figure out happend to me. I thought it was a head gasket at the time but it ended up being cracked ring lands.

 

[awdtalon21]

I think he should have done the test also, maybe he will have the head off soon. I would like to know what he finds.

 

[konvict1981]

I'll be doing the same thing this weekend. I have the same symptoms as you. Tell us what you find.
