We have always had a
oil leak problem with the sticks that are sent to go down the side of the cap. Some of the blocks because of age and being run hard over the years do not fit as percise as they once did. We use the cheese wiz style canister of silicone. we leave out the sticks and fill this void with silicone all the way done. we pressurize this area with the can untill we silicone coming out from the cracks between the cap and block all the way up. We then wipe it even with the cap. We also put a small bead between the cap and the block at the main saddle. We will also turn the seal a small amount out of the block and the cap so there is no crack where the cap meets the block. This is just what we have had the best luck with. Good luck, you got love this stuff why else would we go through so much greif.
