Pulled from the oil pickup....
Globs of RTV, chunks of gaskets
Some bits of foil, (no doubt from the bottle seals on brake fluid, power steering fluid, antifreeze...)
a few shards of the cam bearing babbit that were getting chewed up by the cam,
Black plastic bits, lots of em. Some are internally radiused, and look to have either internal threads or lands.
PCV valve elbow?.... but the plastic is too thick for it, I think.
Anybody care to take a guess?
Either way, its amazing the pump could even pickup oil, but when I had the engine running, the mechanical pressure gage read just fine.
