You have..........Grady has been doing this longer than I have been alive.

I cringe also.

Had Kurt’s valve come apart (and this seems very close to me), at the least it would have destroyed a head and a piston. I have seen many cases where it effectively destroyed the entire engine; case, crank, some rods, all the P&Cs, oil pump, some rockers and a cam, and several heads.


I will speculate that the ring(s) on #6 (and possibly #5) were damaged from heat due to the mouse nest. What happens when a ring brakes apart and comes past the piston lands is not pretty and can become exceedingly expensive in a flash.


What are the cylinder leak numbers? Where is the leakage?


No, I don’t think the engine will explode in a ball of flame. The potential malfunction is more sudden and expensive.

Best,
Grady
