OIL PAN GASKET REPLACEMENT

Jeep CJ7

Jeep CJ-7, 1985, 103,900 miles, 258 cu. In. Engine
To repair an engine oil leak, I removed the oil pan, per the service manual and did the seal replacement on the rear main. I installed a new pan gasket (rubber) and it got bungled up on the circular area of the rear main bearing cap, So I took it off again and re-replaced the pan gasket with another rubber one. I used High Tack spray adhesive to help attach the gasket to the pan surface, but it must have still come out of position. Oil is pouring out worse than ever! I'm slap wore out taking that pan down, but now I'm wondering if I should have removed the small strip of original gasket material from the outer circumference of the main bearing cap. I figured it would just make a good surface for the rubber gasket to set on. Now I'm not too sure. Question: what did I most likely do wrong with this gasket? Are cork gaskets better for this application?

If when you say " from the outer circumference of the main bearing cap", you are refering to the oil pan.

If so, the oil pan must be completely clean. All of the old casket must come off. Including on the old casket from the engine.

When you clean them, you also need to make sure you don't scar either surface.
