I just changed out my injectors, oh baby, what a difference. I tried to change out just the 2 that I determined to be the cause of the nailing but the engine ran really rough. So, I changed out all 4 and what a difference. I know for sure I had 2 bad ones, perhaps 3. Seems like I gained a new motor with an extra piston. Lots of power, at least for a 240D. Smoke on start up is greatly diminished, it is much quieter, and lots more power. Need to find some fuel return hose to replace the old ones. I reused the old ones and got a few small leaks. Here's to another 200k of motoring with these new injectors.
