Oil filter mount/adapter screen

[tyler]

My oil filter mount has a passage that ends in a screen. In the interest of "no bits of whatever tore up my engine" going back in the rebuild...what
is behind that screen? Rubber? metal? I have blasted brake cleaner in there from both sides, but I can't see it, so I'm not convinced it is clean.

Rebuilding my motor is coming along...machine shop work all done, pistons and camshaft are in the block. Should have it all buttoned up by, I dunno,
maybe 2024? ha Project creep is strong with this one. Hoping to hear it run by end of March.

I believe that is the pressure differential bypass valve. If the pressure differential in the entire cooler and filter loop exceeds about 4 PSI it
starts to open the poppet valve. Not the same as the internal oil pressure relief spring which vents oil back to the pump inlet above about 60 PSI.
