compression good, no oil use or mix with water
Replaced the turbo (albeit with a second hand one but one which allegedly didn't smoke) just done the valve stem oil seals and still smoking.

Bought it in December from a guy who used it everyday, it stood for a month (being started reguarly) gave it an oil change, ran it around for a day no problems, stood for a couple of days then started smoking badly - its white smoke with perhaps a tinge of blue, which I thought would be darker for rings, probably one gone
