most of the noise was the muffler tapping the engine cradle. After removing that noise I shorted the coils one at a time till I made the noise stop. Then I pulled the pan to take a look around. The number 7 cylinder has a bad wrist pin by the looks of it. However the walls look as good as all the others. There was no metal in the oil.
Actually the oil looked almost as clean as when I put it in.

Looking for some advice. Can I pull and replace just the one wrist pin or do I need to do a complete rebuild?
