Re: killed my domie?
Just looks like the head gasket to me - when you rev it it appears that smoke is coming out of the joint between head and barrel.
That would result in low compression at low RPM.
As to why the gasket has failed, not sure.
Other than that it sounds like a good engine - got to be worth whipping the head off, for the sake of an hour's work you might be back on the road.
