Oil leak update

As some of you know from my earlier postings, I have been struggling with a rear engine oil leak. I pulled the engine (59AB, made in 1946-1948) out of my '36 coupe car last night and today looked for the cause. the graphtite rear main seals looked good but the cork strip that sits between the back edge of the oil pan and the rear main cap had the oil pan edge creating a diagonal indentation rather than straight across the cork, leaving one corner pushed out. Could be the cause of the leak? I think I can simply bend the rear edge of the oil pan to evenly meet the cork gasket.

I have one more observation I would like to share before I put the engine back in. When I was ordering seals and gaskets, I noticed 2 vendors offering crankshaft rear main bearing cap lower seal retainers (for 1939-48 8 cylinder passenger cars). I could not find such a retainer in my rear main cap (stamped 21A 6325). Either it's missing or I have the wrong cap for my engine. Is this a problem? Any engine experts out there? thanks again,
 
Another observation. I just took off the rear cam cover plate and noticed a large brass screw located under the edge of the plate and protruding slightly. I couldn't move it in or out. I don't know what it is for but it could be "another" source of oil leak by not allowing the plate to lay flat on the block. What do you think, File it down or put enough silicone around it to prevent leaking?
 
That plug closes off the oil tube down the center of the engine. It must be below the surface. File it flat.
 
that is the plug to seal the oil galley,it should have enough clearance,if it has been changed it may be out to far and you may have to shorten it for clearance. DO NOT USE RTV too much chance of it pluging oil passages.

My 221 rubber-fiber composite strip was the same way. Actually looked like it got twisted on the ends when the pan was attached. I replaced it with a neoprene strip but used a bit of contact cement to affix the strip to the bearing cap so it would stay put when putting the pan back on.

I also had some 'fun' getting the pan gasket to stay in place on my 221 LB engine. After it was all together, the next day I noticed the oil slinger sitting on the work bench - I forgot to install it on the end of the crank before buttoning everything up. So off came the oil pan and lo and behold the pan gasket was completely out of place near the rear main. The replacement pan gasket set seemed to be of better quality than what I got with the complete gasket set, and it went together ok after that.

Some on here will remember that I have had quite a bit of 'fun' getting this engine back together. In spite of my ineptitude and with the help of advice from many Fordbarners it did get back together ok and runs and idles like a dream. Stick with it, take your time, do it right and if need be redo something if it doesn't look or seem right, and you will be rewarded in the end.
