If anyone can help with THIS one...
Did an oil change today on my '68, with 5000 on a rebuilt engine. In the fram black top oil filter were found two small pieces of yellowish plastic, about 1/4" long, and half that wide. This also happened with my last oil change, but I passed it off as a piece of debris finding its way from my oil rag onto the filter.
The pieces look a bit similar to what you might have come off the plastic collar from a Chevy oil pump (though obviously that isn't what's happening here). Since the pieces were lodged in the small oil galleys of the filter, they appear to somehow be making their way through the oil screen!
I am at a total loss as to what the heck is going on. I have not checked the actual oil pressure, but the car runs fine (w/no noise), and the temperature is normal.
Anyone ever heard of something like this????
