Default Valve cover is off...

So I pulled the valve cover off to replace the gasket and paint the cover. Is it ok to leave the top of the engine open for a few days?

A little off topic but I've been wanting to paint my valve covers, when you guys pull them do you replace the gaskets every time?

Ok good. It's in the garage. Do you know what the torque specs are for the valve cover?

As always I really appreciate the help everyone on this forum gives. Couldn't do it without you guys.

I'd use a wire wheel in a grinder. I'd replace the gasket with a Felpro neoprene gasket. Install it dry (no glue or sealant). You'll be able to reuse the gasket. While you have the valve cover off check and make sure the mating surface on the valve cover is not bent around bolt holes from overtightening. If they are, you can careful hammer them flat.

I hate stamped steel valve covers. The aluminum ones are much nicer and sturdier IMHO. Just don't over tighten the bolts.

+1 on the Fel-Pro PermaDry gaskets. The one piece oil pan gasket is awesome as well.

This is the gasket I purchased. I don't know if its neoprene or not because it was the only fel-pro gasket available for my car. I hear mixed things about using silicone so I'm not sure what to do. Should I be concerned about cleaning the inside of my valve cover as well now that its painted?

When I assembled my engine I used those gaskets on my valve covers and my oil pan. I installed them dry, per the instructions, and they leaked like hell (valve covers AND oil pan). I removed them, cleaned them and re-installed them (valve covers and oil pan) using a sealant. Have not had any leaks since. So, even though they say to install them dry I highly recommend you use sealant on them or you "may" be removing your valve cover again.

My engine had just been rebuilt and everything was new (to include the heads, valve covers and oil pan), so there was no material on the mating surfaces and nothing was bent or distorted to cause it to not seal.

I'm not saying not to use the gaskets as they are very good gaskets. Just letting you know I had to use sealant on them to get them to seal.

That's odd. I didnt use any and I don't have any leaks. Might be hit or miss. Regardless they are great gaskets. The ones pictured above are not it. Permadry gaskets are blue.

That's the neoprene gasket. I've used those gaskets for years. I saw my dad use them in the 70's. Not once have I seen nor had an issue with them. If you use a sealant or silicon, you're just putting a bandaid on the problem. If you install it correctly and it leaks, then the mating surface of the valve cover is bent from being overtightened. It will need to be straightened as I mentioned in my earlier post. If you use silicon to seal it, you are risking getting silicon in the engine and potential clogging an oil passage leading to engine failure. I've seen that happen more than once.

P.S. Where in Colorado are you? I'm up near Loveland.

I'm north Denver. I was told to let the gasket sit overnight with the gasket silicone. I would prefer not to use the silicone if I don't have to. How tight should I tighten the bolts?
Thanks

Just be careful not to get any pieces of old hardened gasket into the engine while you are scraping..I would use some rags to cover inside the head until you are finished...I'm not sure on the six banger but the V-8 torques for the bolts are 3-5 ft/lbs..I have never used a torque wrench on valve cover bolts though.Just snug them down.You will feel the gasket compress and then the bolt will suddenly begin to get very tight..Once you feel that stop!
