Leaking Valve Covers
Okay. So I did some searching on here yesterday and today about which valve cover gaskets to use and how best to install them. It seemed several people swore by the Fel Pro VS12869T gaskets. They are rubber/silicone with a metal insert. They are applied to a clean, dry surface for best seal.
Well, let me back up. I had to remove the valve covers off my engine fresh from the machine shop because during cam break-in, one of the screw-in studs sheared off. I discovered that once I pulled the passenger-side valve cover off (rocker fell right out). There was no leak during the cam break-in. When I pried the valve covers off, the gaskets were "glued" to both the covers and the heads so they basically tore in half upon removal. Once re-installed, the passenger side had a very slight leak (driver's side was actually dry).
Anyways, since I had to replace them I figured I would get some good ones. Well, I cleaned both surfaces and installed the covers with these Fel Pro gaskets, fired it up, and after warming up for a minute, I revved it slightly and then noticed the passenger side started to dribble onto the intake manifold slightly. I shut it off and let it cool down for a few minutes, removed the valve cover and noticed that I put the "Pushrod Side" on the spring side, so I cleaned everything up again, re-installed the gasket and fired it up. It still leaks, more than before I started! It seems to mostly be leaking from the back side. And now the driver's side is leaking from the back side, too.
Am I missing something with these Fel Pro gaskets? Others seem to have success with them and I certainly am not. By the way, they came with torque limiters or whatever they are called and I re-used the washers that came with the bolts that came with the valve covers.
