'48 leakage

[doc308]

I think that I detect some oil leakage coming from that weird little hole at the base of the front cylinder on my '48 pan. What is a good way to plug this --would something like JB Weld do the trick? I'm aware that that there is supposed to be a plug in that hole, but seepage is coming through. The engine is all togther and mounted in the frame at this point

photos may help.

on the crankcase? or on the barrel?

It's a small , angled hole in the crankcase , just behind the front tappet block. I had read that the factory put a plug in it at assembly. As I mentioned, I think a little oil is seeping out. While the hole is visible with the tappet block installed, I doubt i'd be able to do anything w/o removing it.

My camera is out of order--so pics will have to wait.

I believe you are talking about the welch plug ,where they drilled for the oil passage to the heads.They pop out pretty easy ( thread a screw into it and wiggle it free )and I think you can still get them some where . Now installing it while in the frame , not sure ,I would have to look at mine. You could clean it up real good ,acitone would be a good degreaser & try some RTV sealent , they make it in gray , to hide it . There may be better products around , others here will speak up . I have some photo's some where when I removed the one from my 65 to try to clear an obstruction in there .
