PLEASE HELP ME! I AM STYMIED! I am rebuilding a 83 240D with 616.912, engine number 616-011-28-01, 83 B21. The piston are stamped 90.875, 1 in one place and 64 in another place. They do not have a Star on them.The Mercedes Piston spec table is shown at and does not list these pistons. My bore measures at 90.881 or 3.578". Furthermore why did the builder of this engine use 90.875 pistons-what was his rationale? ARE THESE AFTERMARKET PISTONS?

Sounds to me like you will have to go with the next oversized piston and ring set with the rebore to match. If I remember correctly, I think you mentioned in a previous post that the cyliner walls were pitted. Here's yet another reason to go with a new piston set and rebore/resleeve. From the website you put up on the progress of your rebuild, it sure looks like you have a decent 240. Why not put a little extra into the engine rebuild and assure your long term satisfaction with the car?
