LEAK AT OIL FILTER

[kedso]

My friend picked up this beat 70 with a 318 and asked me to help him get it running.  So I put back the missing parts and cranked her up the engine started and ran OK except for oil leaking around the oil filter.  I changed the oil filter checked the sealing surface but it still leaks bad.  The car has headers and I think someone beat on the filter to make room to get them in.  Is the little threaded neck that the oil filter threads onto a replaceable item?  I"m thinking that's what is bent.

on any modern vehicle no, its part of the block so i would assume no, its been awhile since ive changed oil in an older car tho but i still go with no

Yes, the threaded fitting is replaceable, look inside it for a 3/8" square drive.

The plate that the filter mounts to is stamped steel and it can also be bent; the plate is a source of many leaks.

Thanks  I will salvage the parts off a spare engine and swap them in.

TIGHT TIGHT TIGHT that stud must have been torqued to 150 ft-lb !  There is a round gasket behind the plate that had a crack in it and that was the leak.  Other members should watch out for this it's a cheep little gasket that can cause a lot of trouble.
