ok this is the deal, my friend has a 95 ls fully built turbo, obd2 block obd1 head. He is smoking blue but the rings were replaced recently and valve seals are brand new. He hasnt ran the engine hard at all. maybe has 35 easy miles on it since the new rings and seals. The pcv system has been all jacked up`since he has been turbo. it has always smoked blue since he has had the car built. Would improper pcv cause it to smoke blue? (has serious blow by) how do you properly run the pcv system with skunk2 IM? any suggestions?

 

you sure one the seals in the turbo itself isnt leaking?

 

there is a chance that oil is pushed through the line into the engine
take off the pcv hose and see if there is oil in it
if there is he should invest in a catch can
