Seems like I remember the -2 casting having the slash marks on both sides of the big end? That way the rod can not be put in upside down. It was a manufacturing thing as well as service aid. I usually spend a little time making sure no flashing is left so oil can get into the big end easily. I have considered adding a hole in the small end well? That way the wrist pin would be oiled better, but decided against it since wrist pin oiling is not a problem on this model. Don’t fix it if it ain’t broke!
