Just installed new valve cover gasket from low range with a very small amount of high temp red rtv on both sides of gasket. Originally under torqued but after proper torque (3.0 ft lbs) still leaked oil like crazy after about 1-2 miles drive. Could valve cover be warped? Is using rtv reccommended or not? If I try again do I need to buy a new gasket? Leaking all around valve cover. Suface was clean and extra cleaned on engine block before install.
