'69 Bcuda 340 loses cam plug in rear of engine
Not your issue, but
Once upon a time;
I had a 71 Monaco 360 auto that wore the crank thrust bearing so far that the convertor-bolts got into the Camplug. The trans was leaking oil so bad from other places, that I dropped the thing, and then I saw the plug. I just caught it!
JB weld to the rescue and replaced the bearing. Phew!
