Thanks RR, your observations confirm exactly why I'm asking the question. The motor in question is in my car, and which was represented and sold as a true side-oiler (and commanded the appropriate price). So far, everything people have told me to look for are checking out as legit, but since the motor is together and in the car, I'm looking for definitive evidence.

I crawled around under it last night, and saw some numbers appearing to be stamped upside down on the side of the top-left cylinder. Too fuzzy for me to make out with blurry vision and poor light. I need to get it on a lift, so I can view them from different angles, with good light, and with my glasses at the proper focal length.
