rear main cap, oil pump and pickup all tanked, and that's as far down as I'm going. Rolled in a new rear main seal, and all reassembled - can definitely see the difference from the others. Oil pump looks brand new - the internal tolerances were all right in spec, reassembled it with fresh oil and bolted it back on with new G8 bolts and blue locktite.
Meanwhile, cleaned the decks, removed the grunge off the pistons, and now chasing the head bolt threads. Noticed there is barely any ridge wall. Should be installing the cam in a couple days, then bolting on all the fresh hardware
