    818 engine smoke

    2.0 JDM WRX engine smokes when pushed hard but fine if driven normally. Turbo has no play, compression good and vacuum good.Any ideas on what would cause this?

    I know Im way late for this, but blow by and PCV system also could be a cause. Normally we start with compression test, than install a catch can.

    the subi motor has oil RETURN air vents around the motor. this will always cause some smoking.

    Take off oil filler cap with engine running and see if smoke comes from there. Compression test dry then with a squirt of oil in cylinder will tell the tale most times.
