I am fixing an intake oil leak and was wondering weather I should use rubber or cork end gaskets to go across the valley? Is one better than the other?

I've had real good luck using a thick bead of grey RTV at each end and not using the gaskets at all.

I agree also. With an aluminum intake (Edlebrock) they tell you to just use silicone. I tried rubber and it worked for a few trips and blew out a little (leak). Now I just use a THICK bead of the grey, sit the intake on it and hand tight. Then after about 20-30 minutes tighen a bit more and finally torque after about an hour. Has worked for me so far (On a Ford) >:D

Another vote for a thick bead of RTV, after having my block decked, the amount of material removed eliminated both the cork and rubber. I put a real thick RTV bead on and then carefully lowered the tunnelram on the block. Cranked it down and for the first time NO LEAKS! I was so tired of blowin' oil all over the transom. ;)

...was wondering weather I should use rubber or cork....
Using a rubber always seems to retain the lube for me; on the other hand, no matter how many times I put a cork her mouth somehow she manages to keep bitching....

Trash the end seals, "peen" the end seal ares of the block and manifold lightly with a punch and small hammer then use a bead of "right stuff" (sealant)
on the ends ,the stuff "vulcanizes" and will not leak been using it for years and lots of motors never found a better product .. my 02
re rubbers and cork , CORK is my weapon of choice ;D

Carefull on the RTV guys. I agree on the elimination of the gaskets but don't let the backyard hackers out there use an entire tube of wonder goop. Use it to fill the gap not the valley. If you end up with enough to have to trim off on the outside with a blade you may have enough buldging into the inside that could get into the oiling system. Be moderate in all you do when using silicon. Go nuts on the race course.

Right, what you got hangin out you got hangin in. So save the blades for blow. I use black RTV and just enough to get a nice little bead sticking out that you can see. I bumped the bead comming down with the manifold one time and it had a little whoopty in the bead so the guy I was working for told me that was ametureish, very ametureish. So I told him Fuc you I quit. It was a big ole cast iron tri-power 409 manifold, shit happens.
