quote:maybe the roll pin I used wasn't hardened
Scott,
You may have gotten a Chinese roll pin, or your oil pump may have sucked up a piece of something that was in the oil pan. If the pin were too hard, it would be brittle and shatter easily.
Try looking for a roll pin at an aircraft parts supply. All of the aircraft parts are supposed to have traceability. Try Aircraft Spruce. They are located near you in Corona.
A spiral roll pin is available. McMaster-Carr has them, but I don't know where they get their pins.
