[liftedwj21]

Ok so I have a new turbo and a oil restrictor that's a 2mm hole or so and a I have a breather of the cover on my m20.. Was running a catch can still was getting blow by! With the new turbo will it smoke for a few? have boosted once and to five pounds. What can I do to fix this? The rings are good!! Help

are you sure you arent boosting your crank case?

Perhaps your catch can is clogged or your drain pipe has an up-hill bend?
