Hello, all

As some of you know, I'm nearing the end of a long project - the garage "restoration" of a 1983 MT 240D.

Today, I'm attempting to measure timing chain stretch with the 2mm lift method.

The first step (as far as I'm concerned today) is determining exactly what I have under the hood. So, I have the valve cover off, and I'm trying to determine which camshaft I have. I have a 616.912 I believe is original to the car. The FSM (the printout of which I left in the garage...) mentions several different camshafts by number.

I can't get my head in there to see, so I wedged my camera in there for a couple of pictures (below, and slightly cropped/rotated/zoomed/enhanced).

The thing is, this looks (to me) like camshaft code "H 19". However, I can't find any mention of any such camshaft code in the FSM procedure. I seem to remember a 6, an 8, and/or a 10, but not 19. (As I said, I forgot my printout in the garage - I'll go grab that in a few minutes).

Looking at these pictures, what's everyone's best guess on my camshaft code? If it is indeed 19, then where do I get the specs for checking timing chain stretch via the 2mm lift method?

Thanks in advance.
