I had crush and leak problems at the cooler adaptor for years. At an oil change, I would move the seal from the old filter to the new location between the oil filter cooler adaptor and the block...you know...like we have been instructed to do by GMC'rs for ever. At the next oil change I'd take it apart, noticing the oil leak and the damaged gasket. Then one day at a Greater Midwest Classics rally, I happened to mention this to the late Bob Drews. Bob said...in his gentle wise tone..."Think about what you are doing here." You are using a gasket here that is designed to be wet with oil and the filter screwed down against it in a place where you are not turning the adaptor against the gasket. You oil the gasket so that it slides as the filter is screwed down tight. You are not turning the adaptor, so there is no need to use oil on the gasket. Get up in there, and clean the surfaces of oil, put the dry gasket in place and tighten it down. You will have no more damaged gasket and no leak. So, I tried it. Sure enough, no leak, and no more damaged gasket. Bob continues to educate us from the great GMC'rs in the sky. I love that guy....
