Hello

It's happened a few times now. While on a long down hill, it will let out a puff of blue smoke !

I think blueish anyhow, deffinately not black. Burning oil?? Oil and coolant levels fine, and not dropping.

Otherwise the engine is running great with plenty of power. Any ideas? Valve stem oil seals? I'm hoping it's not the start of something terminal

Also puff of smoke on start up - white/greyish, not black.......

cheers j.
