While motoring in this evening at low RPM''s, the diesel engine suddenly
started smoking (whiteish blue) out the exhaust, and racing slightly on its own.
I immediately shut it down.
When I pulled the engine cover, there was considerable oil splatters about,
and a little puddling. I suspect the oil came out of the breather tube, but
not sure - didn''t want to restart for a "test." It also looked like oil had
entered the air intake (hence the racing?), probably from the breather tube
which is right next to the air intake. Engine temperature held its own, and
no other signs of distress around the engine.
Any ideas on the cause? The engine is a Universal M12, about 15 years old.
