This is just a thought. I have already done my right side of the 3.9L but I still need to the other side. Would it be okay? My plan is to thoroughly degrease the valve cover itself. Then put a very thin film of high temp RTV where the valve cover gasket would rest. Then I would install the new valve cover gasket and let this set up. Once it sets and the valve cover gasket cant come loose reinstall everything. I am hoping by doing this the gasket wont slip out when I am trying to reinstall it.
