Overhaul needed

that is the easy one to change. the engine is going to get removed.
 
seems like photoshop, we've popped a cylinder on an 1830, feather the prop, on the ground there was oil everywhere. Photos show a very clean cowl, don't think so, but I've been wrong before

Pima Air & Space Museum in Tucson

"The museum decided to display the Skyliner with the bad engine on it and a substitute cylinder poking out.”

Were the cylinder base nuts from China?

Base nuts are usually still place, with the cylinder base studs still attached. every one I witness the case was ruined, some we never found the piston, but I think it was in there some where.
 
It really gets scary when it happens to #3 when #4 is feathered.

Bet the most of the oil is in the lower cowl, and wheel well. we can't see there.
 
I know someone who maintains a P-51 and he showed me some recently removed cylinder hold down nuts; they crack on a regular basis and there is no good alternative to the ones they can get. They change them on a preventive basis.
 
Never seen one come through the top. But have seen one go through the bottom once. and bounced across the floor. What a mess.
