Ball bearings in my oil screen!
I posted this under a different post but now have a more specific question. Where could the 12 small, 3mm, ball bearings which I found in my '79 300td oil pump strainer have come from? There is also a part of their retainer in there. The size of the retainer would point to the bearing belonging to a shaft around 3/8"' in diameter.
The vacuum pump has been suggested. Any other ideas of how ball bearings got into my engine oil?
