3 witht he replacement gasket lightly abrade both sides of the rubber seal with a 300 - 400 grit sand paper and then clean with a rag moistened with same solvent used to clean engine. (seal is coated with mold release agent used during manufacture, selants will not bond to mold release agent, so we abrade it away with sand paper)
you want to sand until both sides of the seal are no longer shinny. Be careful not to pull on the gasket tooo hard or it may stretch.
toquing the bolts with a torque wrnch is very important, not so much to be sure the bolts are tight, but more to ensure that they are all the same tightness, if one is looser than the others it will be more likely to leak.
