What Engine is this???
 

looks like a M54

Ooops!
 

YES. I guess that is what it is. Listing says it is in a 318ti. For some reason I thought it looked like it only had four cylinders and was some sort of rare plastic valve covered 4cyl. Looks like they just have it listed wrong. Wondered if it was the S44, but that's not what they look like either.

I can clearly see 5 of the 6 cylinders, and the S44 is kind of a myth in the first place, the S42 was a 2.0L used in touring cars but whether or not they made an S44 is subject to debate, plus I highly doubt either of those engines could have found their way into a car in the U.S.

Yes, I can clearly see it too, now that I know it also not in a ti, and I agree with you on the rest as well.
