OK so list of potential causes:
1) valve stem seals
But this would produce smoke at all times?
2) piston rings
But would produce smoke at all times?
3) headgasket
New one fitted after head skim
4) turbo cartridge
Bearings inside failing?
5) crankcase ventilation
This seams to work fine. No pipe link to intake manifold fitted. Goes from flame trap to catch can.
Help?
