Hey Brian, My 240D would do a wierd shaking at idle sometimes once it was warmed up. I got a bottle of Diesel Kleen at the parts store, waited until I was low on fuel (like 1/4 tank) and put the whole thing in. Thats way over the concentration they suggest but it did the trick. I also use Diesel Kleen to prefill the fuel filter when I change it. It smells alot like diesel purge and seems to work similarly.

Yes, the valves were adjusted about 8 or 9 thousand miles ago when the new (used) engine was installed. And the engine has supposedly only about 120k mi. on it now. It is a nice peppy engine and starts quite easily. Oh, and I replaced all the glow plugs about 2.5k mi. ago. BTW car is 83 240D. Continue reading on and help me solve this mystery - it may be related to these other conditions: The only other problem that I can cite (and may be related?) is that of a slight miss just after it starts. Every few seconds it misses. This goes on for the first 10 or 15 seconds, and mostly clears up if I give it a touch of throttle. And along with the missing is some unhealthy sounding knocking and pinging. Oh, and every once in a while when I start it, and these conditions are present, it smokes quite noticeably. Then the smoke stops after 10 or 20 seconds. If I throttle it at this time, it just makes more smoke. But this whole smoking business is the exception not the norm. Then when I do accelerate before the engine is operating temp., the knocking and pinging are still there. Lately, even when completely warm, it can be heard to ping under acceleration once in a while. I did ask the list about this a while ago, and the options presented included running some diesel purge, doing the Italian tuneup (I always get hungry when I see that), and the more troubling option that I may have bad injectors or cracked prechambers. I have not yet run diesel purge. But I do think that I get something approaching Italian on it on a fairly regular basis. That is if I understand the magnitude of romping required to qualify as a Nunzio. I understand that it is more about pushing it hard, say, up hills and when completely warmed up. The heat and load on the engine are more important than the mere revvs, yes? I do have an aversion to revving the engine high. Wish the thing came with a tachometer and I knew the redline. Yes, I know you supposedly cannot overrev a diesel except for by downshifting. Brian 83 240D --------------------------------- Looking for a deal? Find great prices on flights and hotels with Yahoo!
