Who uses silicone
#2
I just got through trying the neoprene and then cork without anything. Cork did better but still leaked on the back side near the firewall. Plan to use some sort of non-hardening sealer of some sort.
And yes - I verified that my valve covers were straight and not bent from over tightening..aftermarket which is likely the issue.

I use a cork gasket with gasgacinch or Indian head gasket schelak. I also only torque the valve covers to 20 INCH POUNDS in a cris cross pattern. Let it sit over night re torque. Then I drive the truck and re torque. I have had no leaks in the valve covers following this method. Just make sure your flanges or as flat as possible or by new ones.

Silicon and cork is a tricky combo. Silicone acts a a lubricant and also can soften cork when wet. It may cause gasket tears if the joint is torqued with wet sealer. The gasket basically squeezes out. If used with cork, use sparingly and tighten the joint finger tight. After the silicon has set up, a couple of hours, tighten completely. I generally prefer other adhesives or sealers - like spray trim adhesive or high tack - with cork or use it dry.
