I know that this sounds crazy, but I have a 272 that was supposedly rebuilt, and since I can't get oil to the passenger side, I was considering drilling into the bearing from the top while turning the oil pump to possibly float out metal fragments. I am pretty sure the bearing was not installed correctly and since the motor at this point is leak free, I was hoping to not tear it down.
