My ex plod now has 266k and has started to smoke, infact it bellows out smoke at an alarming rate, but only when on tick over when warm, but not all the time, if I lift revs by say 200 above tick over the smoke stops. The smoke only appears if sat at tick over for 30 sec's or more.

I have checked PCV and all seems ok, cant see any oil leaks apart from a small one on turbo, any ideas, I had thought seals on turbo but when driving or accelerating hard there is no smoke only when idling, lift revs slightly and it stops. The smoke is bluey white and smells of burnt oil.

Look forward to your thoughts.
