I'm trying to remove my valve covers to polish, however, I can't seem to get them off. They are frozen on there! I tried a rubber mallet and a putty knife with no luck. I can see the edges of what seem to be cork gaskets under there.
Hmmm..just have to keep trying to convince them they should with the mallet. All four corners and in the middle a few solid blows each usually releases them..Another trick is to hit and pull at the same time. If you can get your fingers in a breather hole front or rear..and pull and whack at the same time..They will sometimes pop loose this way..Careful using the putty knife..you can scratch your cover...or pick up a few stiches...Good Luck..Hope they weren't put on with locktite......Just Kidding.. :jester :rolleyes:
Sounds like someone used a gasket sealer on them the last time they were installed. Try using a razor knife to loosen the sides up. Be careful if you use a pry bar you can bend the edges.
Some people used "Gorilla snot" or 3M adhesive to put them on back in the 80's. We picked up a 350 by it's manifold one time to see how tough the stuff was. :eek:
Yep....3M adhesive used to be SOP in many garages.
You CAN use stuff like that on valve covers, as long as you ONLY cement the gasket TO THE COVER. Rubber gaskets are less prone to "welding" themselves to metal than cork. Plus they generally give a better seal.
If you are worried abour leaks you can use RTV, but even that is some pretty strong stuff! I never glue the gasket to the head. And the only real reason to glue it to the valve cover is to make it easier to install.
If you are experiencing leaks, then either the gasket isn't lining up right, or something is warped. They now sell studs for the valve covers so you just drop the gasket over the studs and then drop the valve cover on the studs/gasket. Shouldn't need cement at all.
