Review on Permatex 80011 Form-A-Gasket #2 Sealant - 11 oz. - Single Pack by Larry Lackings

There are many brands of this type of product but I always trust them. Valve cover gasket changed on Frontier. I don't know why the manufacturers design it that way, but the seal channel is on the cap you put it in, not on the motor. So you have to hold the lid in the air with the gasket inside and then align it to put it down. This product is needed to keep the gasket in the groove so it doesn't fall out due to gravity. Worked great. The minimum quantity served its purpose and didn't sell.
