I don't like the fact that groove is there, I'm sure someone must have thought it was a good idea, I've gone this far I might as well see what will happen. I could always have the main cap re-babbitted I suppose. Even though I plan to run this on a stand, I know that will not tell the whole story. I can't imagine a lot of crankcase pressure with the large opening at the filler tube but under heavy load maybe, especially until the rings seat. My old engine leaks too, if it's not horrendous, still might get me by while I have the original gone through.
