ok my sapph smokes. I am trying to work out the problem. I thought it was the turbo at first, but i'm starting the think it might be something else....

OK, I get a bit of smoke on full boost which is grey / black and not too serious - might just be the chip over fuelling.

Now - on over run, even driving off boost I get blue smoke... and lots of it and the smell of burning oil If i'm stationary and rev hard, it also smokes blue smoke...

Valve stem seals?

Any ideas people?
