Does anybody have a tip or technique to help on my oil pan gasket install???? I am working on a '52 brub with original 216 and have had the pan off 3x mow and it still leaks in the front. I've looked closely and it sure seem to be from the front pan valley. Thought maye the timing cover but doesn't seem to be.I had a new gasket but am gonna get another one now to make sure. Any help????
