today we stripped the engine down to the block and rotating assembly.
When we pulled the 2,4,6,8 cylinder head off a piece of metal was on top of the piston, obviously beaten to smithereens. (I have pics but am waiting for my wife to email them to me cause my flip phone sucks.)
We couldn't figure out where it came from but know that it is the culprit of our noise and smashed plug.
We had the heads on the bench looking over them for anything that was broken but seeing nothing. I noticed the intake valve(2.02) on cylinder 8 seemed to not be flat against the seat.
Sure enough, using a light down the intake port I could see it getting past that valve.
I believe the bits came from the valve seat and will confirm tomorrow when we get back at it. We didn't have a spring compressor and he had to bowl tonight.
The heads are 1968 so they should have had hardened seats installed for use with unleaded fuel. If they didn't, the seats will beat themselves to death. We will have them done if needed after we check the PO's receipt pile.
