I have and older T3 and have noticed some white smoke coming from my tailpipe while at idle, short times after boosting. This condition disappears when driving but has been getting progressively worse as of recent times.

Could excess crankcase pressure and a not so short oil return line be saturating my T3 seals ? If so, should I remove the PCV ?

i have white smoke during a cold startup. Funny thing is that itll only start at around 1K rpm. I recently changed the oil and couldnt really find any trace of water. not much help sorry.

both myself and my turbo GSR friend have a bit of white smoke that comes out from the tailpipe when idling around.....

I know what this symbolizes (coolant in combustion chambers, cracked headgasket, etc), but I doubt that we have this problem because the compression is fine on both of our cars, and the motors are in great shape.

I just assumed that it was condensation, but these symptoms seem to occur even when it's dry and hot out..

question, is there any other way for coolant to enter the cumbustion chamber other then a bad head gasket?

in my case i notice a lot of droplets building up in the exhaust tip. I dont really have to fill the car with coolant, and i didnt notice any water in the oil.

not seeing any smoke with a cold start and am holding 21 inHg steady

-cracked cylinder
-headgasket
-head not torqued enount to the bottom
-crack in the radiator/ hose
-bad water pump

couild also be valve stem seals

hey i just got a full rebuild w/ all the gaskets changed on the motor. 3-5 minutes after idle my car also smokes alot of white smoke. i mean alot!!! i'm going to remove the turbo from the car and run all motor to see if it's the turbo or the rebuild. i'll keep you guys updated.

well its burning all the oil on the manifold and turbo. Just let it idle a little more, but if its like nonstop then check it out..

also i think if you don't hae a cat it will be more prone to a little smoke..

X2BOARD

That is true, but the smoke from no cat is on acceleration, not idle.

The smoke is not constant and happens at idle after boost.

I would pull the head and check out the gasket before it goes when your at 6k. It could be leaking just a few drops into your cylinders for now, but it will get worse.

Well, removed the PCV plug from the valve cover for a run.... wooo hooo was that a mistake ! oil everywhere... (lesson learned). So I put it back on and as Murphy's law states... the **** started smoking even more... it now happens EVERY time I come to idle, whether I pass 1 psi or not !

And the smoke is alot ! If I were in Cali they'd arrest me for killing birds and obstructing low flying aircraft.

The only good news is it is in the 50's in Miami and I gained like 0.5 psi and the car is crazy fast... too bad I don't wanna boost until it's fixed... had to let a CL type S drive off with my pride tonite as I stayed below atmospheric

I will check the headgasket tomorrow, thanks for the info so far fellas !

ROFLMFAO!!!!!!!!!!

Shortened my oil return line and built a tubing system to route excess oil from the valve cover to the outside, I think the turbo might be still retaining oil after boost.

The smoke is down considerably, but it's still present for brief periods of time.

Anyone out there totally bypass the PCV system and built a pressure relief ?

BOV sounds odd... but that's another topic...

its a magic show... isnt it supposed to smoke like that?

"hey, your car smells like **** .. but atleast its running."

X2BOARD

Pffftt....

Shadow, you know full well that the smoke that normally eminates from my chariot doesn't bring you down....
