Hi All, and thanks for trying to solve this mystery.

First, it is not wax, it's definitely metal. It was not between the spring and valve, it was after the valve. I took the spring out but the valve was stuck, so I forced it out from the other side. I got it out with this debris.

I agree that nothing of this makes sense. When I got the engine it lacked both oil thermostat and oil pressure sender so my guess is that at some point this got into the engine when it was sitting (for how long, I don't know).

I don't know what an "oil way baffle plug" is. Taking the cylinder bolts out we used heat from a heat gun. Is it possible that we could have melted something?
