I have started a new engine build for my 240d. It was tired when I got it and now even more so. Will keep driving it until the new engine is ready, then swap.

I am starting with a rebuilt short block(1983 616) from another forum member, that opted to use a 617. This has new liners, pistons, rings, polished crank, and new bearings. I will rebuild the head using valves for the turbo 617 on the exhaust side. New cam, cam bearings, everything in the head basically. thanks to Phil from Peachparts for helping find everything.

Once this is together then I will mount the turbo, a k26 from a 300d while the engine is still on the stand. As I have found that reaming the pre chambers holes helped a lot on the old engine will do the same on the new one, and will for now move the tuned up ip over. A new pump will be built with larger elements and when ready will replace the old one.
