Oil filter plate leaks?

Don't use any RTV on oil pressure stuff. The block has to be surgically clean and all remnants of the old (outer perimeter) gasket removed. No grease or oil on them. The plate has to be flat, no oil or grease, and no traces of the old gasket. Make sure any scraping scars are polished out if you beat it up... Use the inner gasket, plus the perimeter gasket, torque it well, and it shouldn't leak. RTV is asking for a problem IMO.
