Hi, I have just bought a bj41 and it’s currently leaking oil from the oil breather pipe quite a lot, also there is lots of white smoke coming from the exhaust any ideas what could be the cause ?
 
The stink pipe, or road pipe, vents crankcase gases to atmosphere. Excessive vapours indicate that the engine is worn out, specifically piston rings/cylinder liners. Do a compression test to confirm.

A lot of white 'smoke' can come from various issues, a failed head gasket, cracked head, valve problem, low compression, holed piston etc.
