1G Oil leak at OFH

[dsmBear]

Just did an oil change had a pretty big leak near OFH. Never had a problem with this before so i research and most likely culprit the orange o-ring for oil cooler.

I take off filter and prepare to take the 33mm bolt off and turns out I don't have one. I have a 6 bolt oil cooler shown here, did I maybe just mess up sealing the oil filter?

Most likely.

As with the non-turbo and 1990 turbo oil filter housings, the FF OFH has the threads for the filter cast into the housing. There is nothing other than the seal of the filter itself preventing oil from leaking out. Make sure you lube the seal on install.
