rear main seal install, cam plug, oil galley plug
these are the stuff I use, I showed a picture of where I put the flange sealant, I always use in , I did a alfa Romeo engine and they leak from the flange of rear main , she borne dry I did it like 6 years ago, and plenty of 3.8 gm engine. and I would defiantly use the rear main insert to silicone in the oil pan gasket.
good luck
