318 oil filter base leaking!!! i can't seal it up!

[451Mopar]

I’m having the same problem with a 73 La 318 I’ve tryed twice my engine is in the car trying to prime it with cordless drill problems 1/2 qt on the floor but I do have oil pressure think there’s surpose to be a gasket on that double sided nut that holds flat plate to block the other side the filter threads on have a great holiday gonna ,try again tue

No gasket on double sided nut, just the large outer seal under the plate. You can tap the center part of the plate down with a hammer a bit from the back side if it contacts the block before pulling tight on the outer part of the plate to block gasket.

There are some newer gaskets that are too thin. Just ran into this with a replacement plate. The supplied gasket allowed the center of plate to contact the center boss without the outer edge of the plate contacting the block. Thicker gasket from the parts store fixed it.

very true, but it is brand new... should line up first time

Just because it's new doesn't mean it's right.

With all the cheap import parts flooding the market you have to check everything...
