Green95XJ, I'm guessing from your handle that you're getting this for a '95 valve cover? If so, '94-'96 (and other years I'm assuming ... but I know for sure on those years as I have that FSM) the stock valve cover gasket is a pre-molded-in RTV that is not replaceable. In other words, don't use a gasket on it unless you're replacing the valve cover itself. The FSM will have you inspect the seal for cracks and if found, just lightly fill the crack with RTV. Otherwise, it's reusable as long as you don't have cracks. Make sure you torque the bolts to spec and evenly. If its leaking now, it's most likely just not torqued properly.
