Not good. Yank the motor out. Probably nees a set of slugs and a bore.

I would suggest doing a leak down test on the engine before pulling it all the way apart. Even cold it will at least give you an idea if the rings are hurt. Sounds like rings though. May have nipped a piston.

Hard to tell but in the pic's there look like there is some Aluminum on the center electrode

Did that happen in Camden?

BRUCE SEROFF

yes

BRUCE SEROFF

had to bring this back to the top.....

just an update since last post. detonated piston. aluminum fragments all over the place. needed machining, pistons, rebuild etc etc.......

all because wrong plugs were put in. mechanic aknowledged the error and said he would reimburse me for the rebuild. Obviously, he will not be doing it.

as long as he makes good on the rebuild, I will not mention his name, publically.

motor is just about done.
