Your silicone gasket should be bonded to the valve cover for best performance. The bonding process will ensure proper positioning of the gasket when installing the valve cover.
Thoroughly clean the sealing surface on the valve cover – This is where the new gasket will adhere, so after you’ve cleaned it, wipe with alcohol or brake cleaner and a clean towel.
Bond the new gasket to your valve cover by applying a thin bead of automotive RTV silicone gasket maker to the valve cover, and position the gasket evenly.
Tape can be used to hold the silicon gasket in position while the RTV cures. For best results, place valve cover face down on a flat surface during the curing process (which will be specified on the product label).
Once fully cured, clean the mating surface on your engine’s head, drop your valve cover in place, and reinstall mounting bolts or nuts. NOTE: You will no longer need to tighten these fasteners beyond ‘finger tight.’
For best results, place your socket on an extension (no ratchet), and tighten by hand in a spiral pattern or as specified in your service manual.
For your next service interval, simply remove fasteners, lift valve cover, set it aside, and reinstall after servicing. No need to re-attach!
