February 25, 20206 yr When draining my oil I found a thin washer/ shim attached to the magnetic part of the drain plug. There have been no unpleasant sounds or performance issues. The oil looked normal and without metal shavings. The inside of the oil filter looks OK. The washer was folded with some linear rub/ wear marks but not horribly chewed up. At the last oil change I did have the oil pump removed. The parts diagram shows a thrust washer in that location so it is suspect that it did not go back together correctly. However, it is the wrong size for that location. The parts list shows that one as 8.2 x 15 x .05. but the one I found is 12 x 17 x 0.35. Does anyone know what this may be?
