47-55.1 Chasing annoying oil leaks

[TX3100Guy]

While I am waiting for some bracket material to deal with mounting some additional fan capacity for my radiator, I decided to chase some annoying oil leaks on the engine.

The first leak to be deal with was on the pushrod cover. There was a small leak (as determined by the use of UV fluid in the oil and a blacklight flashlight) coming from the back lower edge of the cover, dripping down the bell housing. The cover had been installed by the engine builder using aviation gasket sealer and it just wasn't able to fill in any minor gaps in the cast aluminum pushrod cover, so I pulled it off and using a new gasket and Ultra Black RTV sealed it up good.

The next annoying leak was coming from the oil pan gasket, this time the drivers side rear corner where the rubber gasket in the crank rear main meets the cork gasket. Again, aviation cement was used and no RTV, so I pulled the pan and have plans to put a new set of gaskets back using the same Ultra Black RTV as I used on the pushrod cover.

However, I had been also chasing an annoying drip coming from the oil pan drain plug, or so I thought. I had already put two different washers behind the drain plug and still had a drip. Not very much, a drip or two every day. Today while cleaning the oil pan prior to reinstalling, I found the culprit. The captive threaded section had split the sheet metal of the pan and I was able to see two small pin holes of light as I was cleaning it. The photos below are of the inside and outside of the oil pan after I cleaned them up.





My question is, should I attempt to seal these pin holes up with JB Weld on the inside or outside OR should I weld a small area around the captive threaded section on the inside?
