I have tried it, seems everthing under our sun , but not this , it was suggested to use a new gasket ,the cork and rubber mix,then the secret is using white lithum grease, will this work ? thanks for your input , al

Make sure your gasket surface, of pan, is flat, and that mounting holes are not "dished". Then...you should do better. DO NOT OVERTIGHTEN!!!!

My "trick" is make sure the pan is flat, especially where the bolts go. I cut my gaskets out of thicker cork/rubber material. I also use Gasket Shellac on both sides of both surfaces.

Because of the age and questionable threads, I use bolts 1/4" longer, with thread lock on them. Torque was applied 6 years ago by my 6 year old grandson. No leaks yet.

What ViewMaster said, then drive it a few days then re-tighten using just a small 1/4 drive ratchet and snug 'em up.
May have to do that a couple times...

Oh,and make sure you've got all the old gasket piece off -s clean and flat on the case and pan.

The cork nitrile gasket is our favorite (our pn U-4)

Then replace those grade 0 factory bolts with longer grade 5's and use flat and lock washers. Do not over tighten. The lock washers guarantee constant torque.

The oil pan gasket that I sell is the best one being offered by any of the vendors. It is a composite one that I have been for atleast 6 years. Just ask any of the racers and they will tell you. But remember you must make sure that the pan is flat and do dimpled holes. I have it listed on Ebay in my store.

There is a nice piece to give better torque on the bolts. Check this thread for it. Looks really good.

If you have a great and straight oil pan, then the thin original gasket and torquing the bolts to spec. works with a little gasket sealer. Today that's a rarity.

The thicker gasket with a LITTLE RTV will handle the irregularities, but you can't torque to spec. or the gasket will be squeezed out and leaks. If you tighten the bolts just enough not to distort the gasket, then the bolts come loose. Longer bolts with flat and lock washers works for me.

There is nothing wrong with oil pan. And, AFAIC, it does not need a reinforcement rail,

As noted, it has to be straight.

AND, the block surface needs to be unmarred.

After reading the multitude of solutions over numerous threads, I will add another solution used by a previous Corvair mechanic.

The mechanic used two GM paper gaskets glued together with 3M 77 Spray Adhesive - which was used on the pan and block. Torque bolts to 11 ft lbs. Might want to double check the torque for a couple oil changes.

YMMV

I think what Redone76 has done is the trick and why not support the little guy.

While doing a little research, I have found most Cars during and after our era offer after-market pan reinforcement rails for sale. I think I will give it a try, plus it well designed and will not distract from looks (if that is important to you).

I know some "never have leaks" but the only solution for a heavy daily driver so far has been the aluminum pan.

well over thanksgiving break I had time to sneak in the garage and pull the pan, I do not have a hoist , so its lay on blankets under the trike, looking at engine and transaxle with proper lights, now my socalled pan leak is farther up, sticking a wire down the inspection hole the wire has some oil on the end . I'm thinking in 2011 I replaced the crank seal with nytrill, sooo I'm going to pull the engine and check that part out, let you know what I find, al
