Gents, I'm tired of waiting for a new valve gasket every six months or so when I bend a valve or two...or three. What is the preferred sealer for the cover? And does one just put a layer on the cover flat surfaces, including those little tabs that cover oil-filled holes in the head?

Hey! I use "The Right Stuff" by Permatex. However, getting that valve cover back in after using the sealant is a chore.1979 XS1100F

Yamabond, Right Stuff, any ol' RTV sealant. Which ever type floats your boat.

I personally like the Yamabond. No reason in particular, I just do. And yes, the shelf life of the opened tune is a lot longer than the three months they have on the label.
But like a paint job, it is the preparation that will count. Make sure both mating surfaces are absolutely pristine. Check the half-moon plugs on the right side of the head for their viability and seal them in their pockets with some of your chosen sealant. If you are using Yamabond, spread a thin layer on all the gasket mating surfaces and spread it out with your finger so it is very even and there ate no gaps at all. make sure you have enough room to insert the valve cover directly down on top of the head. Tighten using a center out pattern and immediately remove anything that might squeeze out.
Do that and you should have no leaks and it will last until you need to remover the cover again.Mike Giroir

I guess
I am old school. I still prefer a gasket. A small amount of oil on the surface before installation keeps it from sticking and the cover can come off and on several times until the heat makes it brittle. Unless you have a leak with the gasket you don't need to use any bonding agent with the gasket. I am not disagreeing with anyone on the use of the RTV etc... just not something I do.2 - 80 LGs bought one new

And I've mentioned this before, but it bears repeating; if you do delete the cam cover gasket, check for interference between the cam bearing retaining nuts and the cover; dry fit the cover, then move it around a bit, then look for scratches inside the cover. I've run into this several times, general pretty light interference, but sometimes there's enough to prevent the cover from fully seating until you tighten the cover bolts (risking cracking the cover). Some light grinding on the cover will clear this up...Fast, Cheap, Reliable... Pick any two

Spray the gasket with Pam, it will last forever and not stick to either surface.mack

I used a tube of "The Right Stuff" and beaded the valve cover then stuck the new gasket on the cover. Carefully installed it on the engine and re-torqued the valve-cover bolts a few hours later.
When I re-did my valves last month, the gasket was still attached to the cover, but came off perfectly from the head. Was able to clean up with carb cleaner and re-install the cover just fine. No leaks.
I even bought a new spare gasket just in case.
Yamabond on the cover side to hold the gasket would work also.1) Fire up Internet Explorer
2) http://www.yahoo.com
3) type "www.mapquest.com" into the Yahoo search page.
4) go about day as VP managing multi-million dollar financial contracts.
