I'm replacing the valve cover gasket on my 216. I've got Permatex Gasket Shellac.
Do you use it to fasten the gasket to the head? If so, does the gasket go on the head before the cover is installed?
I've used it hold the gasket in the cover, but installed w/o anything between the cork and the head.
Just want to get it right this time...

Others may disagree, but I've always used Permatex between a "cold" head surface and the gasket....nothing between the upper gasket surface and the cover. The gasket and sealant then act as a dam for any oil build-up on the upper surface of the head. I've found that if I do not do it this way, more times than not, I will get oil running down the back of the engine from the valve cover area.

OK. I did it just the opposite last time. And I noticed some old Permatex on the head...

I 'attach' the gasket to the valve cover. But prior to that, I make sure the head and valve cover surfaces are CLEAN.
I tighten incrementally (similar to a head gasket install) and I do not over tighten.
Just info

i would consider using sealer on both sides of the gasket. surfaces need to be very clean. i use brake cleaner. black silicone is very oil resistant.

The one very important item to consider: how flat is the valve cover? Take a look at the two photos attached. By overtightening the valve cover to the engine, you can misshape the cover. Straighten/flatten the valve cover on a FLAT hard/steel surface like a saw table. I prefer applying the gasket sealing material to the valve cover. Just keep in mind when you do have to remove the valve cover, the back of the engine is very hard to get to with a scraper. Also, use a thicker gasket. The Filling Station has the correct one but NAPA does not.

I've straightened the steel valve covers with a hammer more times than I can count. That's why I went to a Wayne cast aluminum valve cover.

Standard practice for all valve covers. I would include the side covers as well on the 216's.

I would advise to do exactly as RAM_51 recommends and seal between the gasket and the head. If you engine has hydraulic lifters you can seal between the cover and gasket as well after ensuring the valve adjustment is good. If you consider using a silicone type sealer I would highly highly recommended using Permatex Gear Oil gasket maker 81182. After cleaning throughly with brake cleaner that stuff sticks and bonds to iron like nothing else. I’ve had only good results with this stuff unlike with the Ultra Black formulation. My engine has stayed oil tight from the valve cover for over 8 years after using the grey stuff. Naturally, you can’t expect to get a good seal if the valve cover is all bent out of shape so take care of that first and get the sealing surface as flat and straight as possible.

After re-reading RAM's post, that's exactly what I did. Permatex Gasket Shellac on the head and the gasket, nothing between the gasket and the cover. 25mi yesterday, and no leak.
