Ok heres the deal... Every time I start up my car white smoke slowly poors out of my exhaust. After about 15 minutes of driving and the engine reaches nominal opperating temps it completley clears up. During those initial 15 minutes my a/f gauge reads 2 bars rich at idle. I noticed that even if I just let the car idle for 15 min. it will still smoke for a while till I put the engine under load. Why is this? Im guessing maybe its bad seals on the turbo and oil is seeping into the compresor housings. I came to this conclusion after I noticed oil sprayed out of my compresor intake . I had pushed my engine hard for about 1/2 hour just before I noticed this. So whats up, any guesses? Bad seals? Thanx

 

sure it's oil? white is usually water. anyway.. do the quick basics. check for water in the oil, and oil in the water. I'm guessing you damaged a head gasket. do the easy checks first. see how bad the oil is from your turbo, then pull your plugs, and make sure they are reading fine.. and if your are belching smoke.. chances are your o2 sensor is already shot!

 

Could be too high oil pressure - time to add oil restrictor...

Remember, when oil is cool it has much higer pressure even at idle than when it warms up.
White colour is also oil... but slowly burnt in downpipe, whilst bluish is burnt in engine.
To be shure.. did you smell that white smoke?
Also, did you check yr oil consumption?

 

At this point Im guesing its high oil presure. Its cold as ---- in the mornings and evenings and this is usualy when it pours pure white smoke. When I take off from stop lights im leaving clouds on the street. I also noticed an oil leak between my O2 housing and my DP. Bad turbo seals? This would explain white smoke, oil burning in DP. This ------- sucks. I droped 55 bones on my oil feed kit, how can I add a preasure reducer to a SS feed line, I cant just cut and add. NE help would be appreciated. Thanx guys.

 

OK, well I decided to go w/ a needle valve to drop the preasure. Where can I get one at ASAP? How much do they cost?
