Hi again guys, sorry for all the posts :)

I have driven my Supra for about 2 weeks now without a PCV valve (Idiot mem I know) and a couple of days ago, when cruising on the freeway it suddenly PUKED out what I think is burnt oil from the exhaust. It's not black, blue/white more likely...

I mean, lots of it to, I hardly didn't see anything in my rear view mirror :mad:

I recently did valve steem replacement and it worked out perfect but now this :sad:

Please help, is it the turbo? In that case, which one? How to tell? What else could it be?

Thanx in advance guys!

You might want open up the intercooler hose before the intake manifold, and if you find any oil there, than it is most likely your turbos.

Milky looking oil is usually a sign of a blown headgasket. I'd check your compression and do aleak down test. Check your dipstick too. If the oil is milky there as well, the head gasket is more than likely blown. Sorry.....

Im confused about this though... do you mean SMOKE or actual OIL... because I cant imagine how some oil shooting out of your exhuast would make it hard to see behind the car, you must mean smoke... that could be turbos... I have the same problem right now, But its White smoke.. although after not running the car for a few weeks and revving it up again.. the smoke was white with a hint of yellow in it... Id like to hear its my turbos, I dont want it to be anything major... headgasket wouldnt be any fun to replace I wouldnt think.

Sounds like what happened to my car. Ton of white smoke and oil coming out the exhaust. It turned out my 1st turbo went out. :(.

Of course Pooshda, I mean smoke, not oil.
However, when I turn the car off it is a bit of oil dripping from the exhaust. Not much but it's there.
Also, I testdrove it today for the first time after the incident and it was soooo tired, no boost at all, only revved to 3K though.

How do I know if it's Turbo 1 or 2?

The smoke is white and its lots of it to :sad:

Thanx!

What do you mean by milky? The smoke is white and thick.

I have no boost so it has to be thew turbos right?

Thanx!

What about if I only get small-medium (I really do not know what to campare it to) puffs of smoke after switching gears under WOT and then when I push on the gas again? In other words I only get the bigger puffs when I push back on the gas after switching gears after I was at high boost! If I do not step on the gas and only switch gears then I see a very small puff come out about 4 seconds after I switch!

You said in your original post that the oil was blue/white. But you meant to say the smoke was blue white. Two totally different things.

Leak down test meaning a pressure test on the intake????

A leak down test tells you where you are losing compression and exactly how much. It is also called a cylinder differential test. You should do a compression test first though. That will give you a heads up of which one to start at.

Sounds like a turbo to me. When the turbo on my eclipse let go, it would puff smoke only after I boosted and let off. As the play got worse...the more it would smoke.

The compression/leak down test would tell you for sure if its the engine or turbos.

The engine is fine, it runs like a dream and has no weird sounds to it, however, the boost is gone an it smokes white as hell from the moment I start it up.

It has to be the turbo, now my biggest problem is I dunno if I'm gonna go single or buy a new/used stocker :eek:

Thanx!

Read my above reply. I'll guarantee its one of your turbos. My car did the exact same thing when my turbo let go. Also check your engine oil, you may be really low or have no oil at all.

I checked immediately when it happened to me...

Oil level is fine...

I will probably go single :D :D :D
