ayalar007, i've been following up on your posts but just reading along quietly. I have done what you have done so far. The way you describe, it does sound like your switchover valve is hooked up incorrectly. I'll take a picture of the one from my 300SD later.
I have cleaned the boost lines (the 300SD was fairly clean, the w123 300D was crudded, W124 300D was fairly clean too), cleaned the banjo bolts (didn't perform on the 300SD, W123 300D crudded horribly, W124 300D also pretty bad), did the switchover valve on the W124 300D, but tuned the alda 1.5 turns CCW on the W123 300D and 1 turn CCW on the SD. Wow - 300SD, WOW!
on the W123 300D, and WAHAHAHAHAHA!!!
in the W124 300D. All of them can hike up a hill faster than before but especially so in the 300SD and W123 300D (put it this way, it can now go up a hill FASTER than flat level acceleration before).
Don't have the guts to do a valve adjustment or turbo waste gate adjustment yet. Going to do a diesel purge on all 3 when the opportunity permits.
I, too, would like to thank everyone on posting these tweaks for the OM617 motor and Dave in particular for the OM603. Without you guys, my W124 will be easily caught up to by properly tuned OM617s and my 617s will be "they're like that because they are diesel and have alot of turbo lag" - Mechanic John Doe
Perhaps we should have a sticky for the first things you should do after acquiring a diesel benz and its "sluggish"??? Does that sound like a good idea?
