so I finally pulled my '86 318 this weekend and I had a couple of over eager helpers that started pulling stuff before I could stop them!! Well needless to say pistons were coming out and caps were getting set aside:violent1:. so tonight I was trying to line up caps by the scuff marks on the bearings when I discovered a miracle! The factory made a small mark on the side of the rod and the matching cap. There was stars, diamonds, shield like symbols, and some others. needless to say I had 7 out of 8 correct anyway but this really put my mind at ease. I just thought this might help some others out there that shared my mis-fortune.
