So I searched (and boy did I search); but I just don't know the appropriate words to find this info:

The oil filter is screwed onto a small metal manifold, which is bolted on using two 12-mm bolts. I can't find a parts diagram with this information. I'm interested in the gasket (or o-ring) that seals this small manifold.

...and yes I'm sorry that I have had to re-post a question that's been asked 200,000 times! I'm good with a wrench, but I'm no mechanic -- and therefore don't know all the appropriate terms.

 

I think what you looking for is probably the oil cooler base.

 

Cool, thanks! Have you worked on yours? I believe there's a leaky gasket under mine. I STILL can't find any blowout diagrams of it though!!!

 

S2 have different oil filter configuration.
are you sure its not leaking from the oil filter?
maybe there are two o-rings?

 

Oil cooler base? What do you mean by that?

You can see it (where the filter neck attaches) here in the pic at the rear of the block. High temp RTV will work to seal it.

 

I purchased new O rings and I still have a leak. Although I dont have the gasket so I will order new gaskets to see if the leak gets resolved
