Replacing valve cover gasket

I am going to use a permadry gasket, but my main questions are what should the bolts get torqued too? And should I use any rtv sealant? If so where?

Thanks guys

55 in/lbs is 4.58 ft/lbs so instead of being dead exact and buying another torque wrench bring em up snug. It is meant not to crush or break the gasket when tightening down the bolts. So just snug them all in a circular direction and then just check one more time. Hopefully that helps.

If you haven't done one before, you ought to borrow or buy a 1/4 inch drive torque wrench, otherwise, you'll overtighten it and it will leak. It is just counter-intuitive how little torque 5 lbs is.

If you don't want to get the right torque wrench, then don't even use a ratchet. Just use an a socket and extender and tighten it down with just your thumb and two fingertips.

This isn't a jeep thing, they are all like this. I killed a motor when I was 17 overtightening one.

As far is whether to use RTV or not, what do the instructions that come with the gasket say?

I did mine recently and it had the cork/rtv gasket and I opted for the $40 Felpro reusable gasket that doens't need RTV/adhesive. It took me the better of 2 hours scraping that crap off the valve cover. If I even have to crack open my cover again I can justify the gasket not only because its reuasble but time and energy it saves and headache of cleaning up after the old one. If you can swing it I'd get the Felpro one.

I replaced the valve cover gasket about 3 years ago with a cork gasket. I never knew about the tq specs then, just made it tight. Guess I got lucky n didn't squash it.

I'm picking up the new gasket tomorrow so I guess I'll see what it says about rtv. This will be the first time I use a rubber gasket over cork

Well worth it in my opinion, just like getting Lube Lockers for the diffs.

If you measure 10 or 15 ft lbs and compare that to guessing you will be amazed at how much too tight you have been going, why there are so many broken bolts and so many leaking ccovers and pans. After you get the feel it's way less than 1/4 grunt.
