Typically if it's the valve stem seals it will blow smoke during high vacuum periods, so idle, taking off... If the turbo is good and comp/leak down test comes up alright, there's a good chance it's the seals... It can be done on the car, but requires the valve springs to come off, so if you have already done them, they have to come off again, if not then lucky you.. If it's at the stage where your seals are stuffed then there's also a good chance that the head is due for a service 2 Link to comment Share on other sites More sharing options...
