Oil filter housing/cap weeping

Just changed my oil today, and during my usual underside check after filling, I noticed a small weep coming from the oil filter housing. Photos attached before and after starting the car. Anybody else experience this? Hoping it is the cap and not the housing itself. Yes I replaced the o ring and oiled it, and torqued the housing to spec

Check the plastic threads found on the plastic cap housing i have heard of it leaking there. also check the metal housing threads but i doubt it be any damage there chances are the fix would be getting a new plastic housing.

I clean mine pretty well every oil change, but it always manages to get pretty filthy in 10k miles. It doesn't drip yet, but I feel that eventually it may need to just be replaced. A metal version with an added fumoto valve would be pretty sweet if you ask me.

I can't see the weeping. My guess it's just residual oil.

The two O rings do the sealing. they need to be the correct place, and the mating surfaces need to be clean enough for the O ring to seal.


might want to clean this off (I like a spray of simple green, wait a few minutes then gentle wash of water)


and then wait to verify where exactly it is leaking.
