ive just bought a mk2 xr2 turbo running a 1.8zvh on a renault 5 gt carb n t4 turbo and need to know why its smoking from the oil breather and the exhust ive took the intercooler off to see if there is any oil in the pipes but all seems fine so cant be the turbo any help on this would be a great help as i cant think wat it could be thanks in advance can add sum pics if any wants to see the set up

 

Stem seals or piston rings mate.

 

I agree mate, stem seals or rings. Would be worth getting it checked from a garage that knows there way round a zvh.
