I'm using the cheap cork gasket with the black rubber ends. I've already changed the oil pan gasket twice because it was leaking around the sides of the oil pan (7 qt claimer pan). Now it's leaking badly from the front seal and no where else. Someone told me that I should have used the thick rubber gasket end. Does this sound right? Where would I get it?

Also, are the one piece rubber gaskets better?

Please help.

Pull the engine out and put it on an engine stand, flop it over, pull your pan off and take the gaskets and seals out, and clean the surface's of the block and pan really good so there is no oil, then place the pan back on, tighten down your pan bolts... and then take yourself a tube of silicone, run a bead all the way around where the pan and block come together, and around the front of the timing cover and around the back main seal... let it sit 5 minutes, wet your finger and then run it around the pan so that you take the excess silicone off, and this also forces the silicone down into the gap a little... let it sit overnight, or for a few days and then have at it. We do this to our pans, and intakes now. Learned it from Gustaf Engines. Works great, no leaks ever.

Are you saying to run the bead of silicone around the pan after you install the new gasket or not even use a gasket at all?

after the pan and gasket are installed, and the bolts are all tightened... then run the bead, and then use your finger to make it look good and seal up al ittle better...

Do you still use the cheap cork gasket or does it matter?

yes, you need the thick front pan seal its about 5\8.

most pan kits come with both the thick front and the thin theres nothing cheap or wrong with the cork rail gaskets.

You shouldnt need any silicone except a dab at the ends of the rubber where they meet the cork rail gaskets.

The thin front pan seal is for the older pans,i'm willing to bet your claimer pan is the newer type(70 and up)so you have to use the thick pan seal,the thin one is easier to put on but it won't seal.

It never leaked from the front before. I guess I got lucky and got the thick seal the other two times. I believe it was leaking before because I over tightened the bolts. Thanks everyone.

on the claimer pans its real easy to over-tighten the bolts and bananna the pan, thats why we use the silicone around the pan, and it actually makes it look a little better too...

I can't agree more with Xtreme12x. WE've had the same engine builder for 3 yrs. now and he does exactly what Xtreme12x said and our engine have never leaked from the oil pan or anywhere for that matter. We take our motor out at the end of the year and other than a little dust on it , its dry and not the east bit grimy. My words of advice would be to follow as he says. Good Luck!!
