Re: Mysterious chips in the oil
As it appears to be deposited there from the oil pump, you are going to have to drain the oil (look for more chips) and clean out the pan and dip trays. Remove the pump and disassemble. As those particles should not have passed thru the pump screen my guess is the oil pump gears may be eating away at the housing.
What has me puzzled is that you said the chips were not magnetic, which should eliminate the oil pump and pump housing.
Is it possible that those chips are old babbit grindings from engine rebuild? Its the only non-magnetic silver colored chips I can think of. They could have been lodged in the oil passage where the pump sits in the block or in the pipe that extends to that front oil chamber. Perhaps pumping just flushed out that oil passage.
