The turbo is second hand its an andy forest one, iv spoke to him and he says its unlikely that the seals would fail

I'm interested in this thread as I have a 2.5L Classic with a return to sump catch can. It is a fairly heavy user of oil and have been told that this is typical of 2.5L engines - also seen threads on forums to support this. I also get smoke at full throttle, which is kind of worrying

Would prefer not to leave Porsche drivers etc. in smoke

Not sure if this sounds strange but, is catch can full and blowing back through. Just a suggestion.
