Ford Lehman 120 Mystery Rubber Disc

[VicTrawler]

I found this solid rubber disc sitting in my oil pan on the starboard side in the vicinity of the flywheel (stbd aft end of the engine). Any idea where it comes from? Looks like it had a hole in the top of it and must've been held on by a fastener of some sort. The hole obviously failed. It's about two inches in diameter.

Looks like a timing port cover gasket.

That's exactly what it was! Looks like the bolt holding the cover to the flywheel housing came loose. Thank you kindly.
