Oil Leak Around Oil Filter

[Hummer Guy]

I've been having a small oil leak around the oil filters for the pass several months or so, it only leaks when the truck warm up. I thought it was the gasket under the oil filter housing, so I changed them and torqued it down, it wasn't, it still has the same leak after about 20-30 minutes of the truck warming up. I heard of people saying the FDC leaks but the leak I have is oil, not fuel at all.

Have you guys had a oil leak around this area? If so, where was it, the common place I hear is the gasket under the spin on filter which I checked and the FDC.

(I have the spin on oil filter)

One of my guesses is that a clog breather can be causing the leak but the only breather that I know is the crankcase hose on the passenger side which seems to be releasing off the crankcase pressure properly

I had a pesky oil leak where the spin on adapter meets the block. Only torquing the retaining nut way above the specs fixed that. I have a spin on filter that leaks unless it is torqued ape-tight. the second one is fine. Go figure.

About to do the same thing honestly, I wonder would gasket maker do any difference

You can try the black adhesive permatex to see if that solves the problem, but I would only apply a small bead all the way around the very outer edge of the filter base so none of it makes it under the adapter. If a piece came loose, that could clog something and make a small issue into a big issue.

I never had any luck with completely sealing oil leaks around the filters till I installed the spin-on filters.

I assume when my Duce stops leaking oil from anywhere. It ran out and I need to add more

Looks like this going to be my first thing, ape tight with a breaker bar
