616 thanks for your reply it was a bit sarcastic but informative non the less. I would like to start out by saying i am not by any means a specialist in mercedes diesel pumps and as far as i know i never claimed to be. I spent a year in a mercedes dealer as a tech and did as much training as humanly possiable so i have a bit of a background with mercedes. At any rate i am a chevy guy (blazer, silverado, trans am, cavalier) but this poor old sad 240d fell in my lap so i decided to "play" with it. Im not telling anyone to do what i have but see no harm in sharing it. I would like to turn the capsule in but it was getting late ill track down a tool and do it properly later but removing the shims appeared to make a improvement (i ran the engine with the cover off and moved the rod). I could see how it very easily could lead to return to idle issues but it would appear quite a bit of adjustment on mine atleast would be required. Besides like you said the improvement will only be on the lower end but god knows these sad little engines need all the help they can get getting themselves moving and i have noticed quite a bit less turbo lag. so...
