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,
Adam
