I have tried prematex super adhesive,and thats stuff from Edlebrock,and some grey stuff.But every time I pull the valve cover gaskets off.They still show signs of oil leaking past them.
Would black,or clear selant work better.I'm using this time Felpro thick cork gaskets.I tried the rubber ones last time they did not work well.

Are your valve cover edges nice and straight?I have used the same set of rubber gaskets for years with no sealer.I have the big long T nut type bolts so I can quickly remove the covers so the little studs hold the gasket in place if I take the cover off.I have no leaks and I can take the cover off in about a minute with no tools.

Scoop, use silicon and glue the gaskets to the covers, then after they set, just use wheel bearing grease on the side that faces the head. Then you can remove them at a later date if you want to paek at your valvetrain and you can just put them back on.

Use Mr Gasket Ultra Seal gaskets. Clean your rails and valve covers. Use studs if possible. The Ultra Seal gaskets have a heat activated sealant on them that works well.Don't over tightnen the fasteners it pushes the gasket out. I have used the same set for 2 seasons so far. I adjust my valves each time I race, so my valve covers come off alot...If you are using stamped steel valve covers, make sure the bolt holes aren't dimpled from being torqued too much.Cast Aluminum ones do a better job as far as clamping force. Just like chrome oil pans chrome valve covers have a tendancy to leak!!!

I'm going to use the clear silicon sealer.

Scoop(love that name),

Something is wrong. I have steel Moroso covers, with the bars to spread the load, and had aluminum Cobra covers and never had a leak with no sealer.
I take the covers off to adjust valves and reuse the gaskets and no leaks.
I run cork Fel-Pro gaskets.
You have to have a warped cover.
Sealer should not be necessary.
Some of that sealer will wind up in the oil.

Ron,
I glue mine to the cover, but it's just for ease of inspection. I use the clear silicon. They really don't need anything. I just do that so that when you put the valve cover back on you don't have to fight the gasket at the track. Steve's idea is a good one. I don't really use the wheel bearing grease, but it won't hurt a thing and might even help keep the gasket from sticking to the head but still allow it to seal.

Joe is correct, the most important thing to keep your valve covers from leaking is good solid stiff valve covers. Heavy cast aluminum covers are the best as far as stiffness goes.

I have a spare set of Ford Motorsport tall aluminum valve covers.... If you're interested... I went to fabricated one with billet rails...

The rubber ones with steel inserts in the the bolt holes from Ford are nice. The inserts stop over tightening and crushing of the gasket. I just greased mine, no leaks.
