Oil leak - pump area

Hi, everyone,

I have (a lot of) oil coming from the oil filter housing (from the nut area circled in the pic).
Do you think it could be the o ring (512040)?
Is there a gasket between the oil pump housing and the auxillary housing?

The housing is sealed to the block by the "O" ring 504365. (And 271879)

Your problem is most likely the "O" ring 512040 as you suggested.
