Hi i have a 1995 Del sol with a stock b16a3. It is an all stock motor and is running apprx 7-8psi via t3/t4 turbo. Prior to the install the car was mechanically flawless and did not burn any oil. I currently have a problem where my car periodically burns oil. It completely stopped burning oil for several days and then started agian. It is not losing lots of oil on the dipstick but at lights and low rpm, the car produces smoke. Could this be a valve / valve seal?

Any info would be greatly appreciated

 

it could be ur return line backing up, or the turbo seals

 

How do you determine that though? The car didnt smoke all week from sunday until today and i am a daily driver. Also how do i check or fix the blockage if this is the problem?

 

How do i verify the problem? Another thing i noticed is that my vacuum in my intake manifold does not have a high vacuum when decelerating in gear?!? Could this mean i have a valve problem?

ANY INFO would be greatly appreciated

Help me out here guys

 

do a leakdown test, check turbo seals and return for blockage or damage
