As you know I have been doing a new engine build with a brand new crank case. Ok so I noticed a small line near the one bearing I was installing this is the stator side shift drum bearing. I also took a pic when I first got the case in, It looks like there might have been a small casting line there and with the heat and oil after installing that bearing I really noticed it. Now I looked at the old case and there is a line. Now I did have to slightly tap this bearing in after heating the case a freezing the bearing a few times to get this in. Now it does look like in the new pic there is a faint line. Should I take this to a machine shop and have them just weld a line just in case to reinforce this area. There isn’t anything on the outside of the case, no stress cracks or anything.
