Even after replacement, my valve cover gaskets leak. I am using the stock TCM p/n 655705A gaskets, which appear to be a heavy paper impregnated with something. I’ve re-tightened the valve cover screws, but the leaks keep coming back, especially on the exhaust valve covers. Will the gaskets eventually compress and seal properly? Should I try gasket sealer? Has anyone had better luck with aftermarket silicone gaskets?

 

Thanks,
