We got there by a process of elimination and looking for track. There is an
oilfeed to the turbo from the top of the rocker cover. Of course if there was excessive blow past the rings there would be pressure there so that confused the issue for a while. But turbo it was and one of the techs suggested that. As I said before there was push back from volvo but in the end I think they knew this was an issue and accepted it. The new turbo fixed it and no reoccurance .
