Hello, I have a 1983 Jeep 258 engine in my 1950 pickup. It does not like it's valve cover oil tight.. I've resealed it a number of times with new cork type gaskets.. I've used a number of gasket sealers including silicone to glue the gasket in place... It always leaks after a few hundred miles.. It always leaks on the manifold side..

Has anyone had luck using straight silicone, with no gasket? Anyone have an oil tight v/c on their inline? How did you do it?
