I am running a H23A1 with a turbonetics T3/T4 turbo. Well the problem is when i get on it and boost it up its fine. But when i let off the gas i get a decent amount of smoke. Its like a blueish white smoke but when i get back on the gas it seems do to aways. could it be my pvc valve needing feeding oil into the intake manifold? would an oil catch can solve this problem? Or if its anything else what could it be.
