over the winter i am going to rebuild whatever is wrong with it but i was wondering if their is anything i can do to pinpoint why it is burning oil. i dont want to have to pull the motor to find out its just the head thats bad.

its a stock turbo gsr. the motor is very strong and feels great. i made 290 WHP on 9psi. the problem is that it smokes a lot. when i drive normal it does not smoke. in higher Rpms (5000 to redline) the car smokes a lot. its very noticeable. when i am in neutral and i rev it to higher rpms it smokes. also, when i let the car sit for about 2.5 weeks and i started it it smokes a little.

compression is 175 across on a cold motor(my gauge is not accurate). when i added oil to the cylinders the numbers didnt move more than 3psi. but this only tells me that the compression rings are good. is their a way to test the oil rings?

thanks

The compression results seem to fit best with bad valve stem seals.

My turbo smoked at the higher rpm's and not the lower. Maybe try a restrictor on the feed.

I placed a copy of this thread in the Forced Induction section to see whether you get additional feedback there.

thanks for doing that for me!!! and the turbo does have a restrictor on it. im pretty sure it is not the turbo. it is in great shape and the car burns oil. i converted it back to n/a just to see what happens and it did the same thing.
