Review Of Valve Cover Gasket Sealant Or Not References. Gasket sealant can be used to make cheaper gasket materials more robust, increasing adhesion and chemical/water resistance. Rubber valve cover gaskets do not require sealant.

Make sure you put abig goob around half circle seals and in the sharp corners of the mating surface. I think the op is talking about valve cover gaskets made of silicone rubber, not talking about using a silicone sealer on top of a (regular) valve cover gasket. The valve cover gasket is an important part of your car's fuel system that goes over the top portion of the engine cylinder head.
The Main Reason For This Is To Keep The Gasket Properly Positioned.
Take off the valve cover and remove the old gasket(s), valve cover bolts/grommets and spark plug tube seals if present. Back when valve covers were removed a lot more than today to make adjustments, etc. If tubed, then i would say "no" unless there is a sharp corner designed on the gasket/valve cover.

The reason for this is the end corks must but up against the side gasket end tabs. Clean everything off, concentrating on the valve cover itself and the cylinder head's sealing surfaces. Compatible 283 305 327 350 383 400 rubber silicone valve cover gasket.
It's Responsible For Sealing The Oil Within The Valve Cover So It Won't Leak Out Of Your Engine.
I've seen this multiple times. I would use some red sealant (high temp) on the corners and half moon areas. It could be shrunken, cracked or rotten, or your valve cover itself may be cracked or broken or one of the valve cover bolts may just be loose, allowing a little leak.
As You Can Imagine, When A Gasket Starts To Fail, It Won't Be Able To Seal Properly And Oil Will Start Leaking Out.
I use chassis grease to hold the side gaskets to the block. Remove the existing gasket and sealants that may stick to the cover or the top of the crankcase. Rubber valve cover gaskets are designed to seal against the valve covers and thus need silicone to make a good seal.

Hi, doing a valve cover gasket job hopefully real quick, and noticed that the manual said to use sealant with the (rubber) gasket in a few spots. The valve cover gasket is a seal that sits between the valve cover and your engine. You have to make sure the gasket surfaces are clean.
