After many years of having my cheap chrome vlavle cover leak like a sieve, I have given up and ordered an aluminum one and a Corteco gasket. With the old one it didn't matter what I did to the gasket or how tight or loose I torqued the valve cover, the sucker leaked. I'm hoping theis new cover will seal correctly, but I'm wondering, what do you all think is the best way to install the gasket? Dry? With sealant? If so, what kind of sealant?
