Well Ive been plagued with a reaaaaal slow oil leak from around the rim of the pan ever since we welded the oil return line on. 3 gaskets later Ive concluded that the pan is slightly warped on the corner near the welded fitting. My question is this, is a b16 and b18 oil pan the same? I have a b16 oil pan sitting around, but just wondering if anyone knows this for a fact. Im gonna measure the two and see where that gets me. If they are interchangable then Ill order a new fitting and take it to a welding shop and have them weld it, my friend did the first one and well it looks bad, lol.

well take the old pan off.... mate it up with the new one and see if all the holes are the same........i think they are the ame pans if i rember correctly

There should be a number right on the bottom of hte pan, what does your say?

B18c's are all P72. I don't know about the rest.
