Oil filter housing leaking, can't get it to stop SB 273

Success!!! Got another adaptor with the same part number on it. It had a different head on the bolt. It was a 3/4 bolt and the one I had on the other was I believe 1 3/16 bolt. Anyway changed the adaptor with a little gasket maker on the circuliar engine mount gasket, did up the bolt, snugged it securely and presto, it doesn't seem to leak. As there was no cork inner gasket on the new bolt I didn't even use a cork gasket, mostly cause I didn't have one. I don't know if it was the bolt or the housing that was leaking but it seems all leaks are fixed now.
