not sure what the head design changes were Jim.....I think the tech mentioned something about the cooling channels that were in the head being different than the old one....I know what you mean about the payments...there is a 99 E300 turbodiesel in town at a dealer with 35K.....its tempting...but due to all the work that I have had done on my current car in the last 24-30 months I think I am going to hang on to the old girl for a bit...in addition to the engine problems my car had had all the "classic" 140 problems....instrument cluster replacement,window regulators,evap core(twice),closing assist pump,front end work(updates)....my tech at the dealer says "why get rid of it..you almost have a brand new car".....I think the repairs since I have owned my car(about 3 years) are about at the $22K mark..mostly warranty..and all work done at either Mercedes of Morristown(NJ) or Crown Mercedes(OH)...so I feel like all the work has been of good quality....or I can take it to bat if I ever need to have a "session" with the regional MB rep again..lol
