I have a '85 Vanagon that I am in the process of putting new heads on.  The PO
ran the van when it was hot and the engine got so hot that it dropped a valve
seat on number 1 cylinder.  I cut the oil filter open to see if there was an
indication of bearing damage.  The filter had a very small amount of metal
chips (like maybe one or two chips every five folds in the filter material).
What I need to know is if this is normal that there should be a small amount
of metal in the oil filter or should there be no metal in the oil filter and
the bearings of the motor have been hurt?
I would appreciate any advice.
TIA.
