Sorry for opening all these topics guys. Thanks for helping me out doing my valve adjustment! Job completed successfully
Before putting on the valve cover, I figured I'd check my chain stretch. Aaand, I am reading about...0 degrees...
So, I lined up the markers on the cam-tower, to where the little opening in the ring is perfectly centered on the mark on the cam tower. It looks like it's not centered, but that's the angle of the photo, I had it perfectly centered (needed to rotate the engine 3 times through to get it perfect, I overshot it every time, fighting the compression)

Soooo... Seeing how I have 280k miles on this thing, and the history of the car is unknown except for that the previous owner bought it from a W123 lover 4 years ago, and Betsie has had front suspension work done, a leather wrapped steering wheel and a dash pad and hood pad and other things that have been lovingly done to her:
