Panhead Oil Filter/Cleaner Cap (OEM 1958-64) (Repairs Required)
This is an OEM filter housing cap with the correct casting number on the interior. Inlet and outlet ports have good threads. The obvious modification here is the tapped port at the top. A previous user wanted an additional port source, so it was machined for an NPT fitting (included, but not pictured.)
Could easily be corrected by a proficient aluminum welder. Or could be capped our possibly used as an additional oil source.
