Have a decent leak emanating from around the oil cooler where the oil filter is mounted. I checked the oil filter and also replaced it and made sure it was tight but the leak persists. I can't seem to find much on the internet about this issue or any help on replacing the oil cooler. I did see one video showing an aftermarket Mishimoto oil cooler conversion being installed, and it showed the oil cooler being removed with a 12mm allen socket wrench. Is there really only one bolt holding this oil cooler to the block? Also, it looks like this "bolt" actually has a port that oil flows between the block and the cooler. Is there any gaskets or o-rings that are needed if I determine I need to replace this cooler? Thanks for any assistance.

UPDATE: Purchased new oring but when I took off the cooler the original oring seemed fine. It did seem like oil was leaking from one side of the junction between block and cooler. I cleaned everything good, applied a little HT RTV and reassembled. Let you know how it goes. BTW, it’s a 12mm Allen for removal, just the one bolt/port down the middle.

How long of an allen key did you use to driver the bolt/hole

How long of an allen key did you use to drive the bolt/port through the oil cooler and into the engine block?
Thanks for any reply!
