I have a 2g with a 20g (hybrid) compressor and extruder in a 18g housing and when I boost (24psi) I always puff whitish or blueish smoke. I have pretty good shaft play(I know its bad), around a 1/4 or 3/8 of inch of play. just wondering if i will need a new turbo? I have to put oil twice a week and check antifreeze every week. Please help!!!?
