oil spray out the top of the dipstick tube??

[sprevett]

never seen that before....but definitely some minor oil splatter on rocker cover/ignition leads/zorst manifold...and the dipstick was half an inch out of its tube...do they all do that sir? might have over-filled it a bit....

Probably a blocked crankcase breather.

i cleaned the flametrap not long ago and the breather pipe to the plenum is clear. Rear breather pinhole is clear too....

Has happened to me too. Had big clouds of smoke as it hit the exhaust manifold! Pushed it back in and no problems since. I think there is also a rubber o ring on the dipstick, might be worth checking that too. My dipstick is quite a tight fit, so it's easy to think it's pushed in when its not.
