Its possible that the crankcase vents are plugged and that you are building up a lot of crankcase pressure from the piston leakage. If that were the case I would expect the valve cover gasket to leak since it is not designed to hold pressure. Since it happens only when you rev the engine, try removing the oil filler cap and trying reving the engine. If no leak then check your crankcase vents, there is one on each valve cover.
