Believe it or not, but if your engine isn't tuned properly and your PCV system working as designed, you will never stop the oil leaks, no matter how many gaskets you replace.
You MUST have good manifold vacuum at idle and eliminate all vacuum leaks (proper state of tune), and your PCV valve, hose, and grommets must all be in good shape. The baffles in the valve cover need to be clean, as well as the vacuum fitting at the base of the carb where the PCV line hooks up.
A RMS will never suddenly start leaking, it is a slow degradation starting with a weep, followed by oily residue, and going to an occasional drop of oil every now and then.
