I have learned a few tips.
1. Vise grips are the best tool I own.
2. When trying to remove the P&C's in one piece you can not pull the cylinder up to high or the rings pop out.
3. You can not push the rings back in with a screw driver.
What is this rubber substance for, an oil leak maybe.
Does the chain ribbing in the housing matter?
I think this is a crack between two head stud holes.
My shop is not as clean as everyone else's.
Sorry about the photos, my camera is a POS, but it was free.
