Larry, "Fix it": loosen and repeat the three step torque procedure.
Take a close look at the clearances above the IP, to make sure you can fit a torque wrench in there. On my OM603 the intake manifold makes it a very tight fit. A smaller torque wrench may be required.

As far as your comment <<Obviously there are other causes for rough idle that also need to be investigated (fuel filters, air leaks, bad injectors, carbon in pre-chambers, valve adjustment on older engines, EDS problems on newer engines, compression, etc.)>> That's why I took it to the dealer - while my fuel filters are new, cannot find any air leaks, have treated it for carbon in the pre-chambers (along with 2 years of 100 mi RT at 67-70mph) I can't be sure of the other possibilities. Obviously, I'm hoping the MB Technician knew what he was doing. I will replace the springs and make sure all is clean - you're right about the springs - seems like false economy not to replace them while you're in there. But I have a question about the possibility of warping the IP body when torqing the DVs - you said it's necessary to "Fix it". How would I do that? Maybe I'd be better off letting the dealer do it?? I cringe at the thought of damaging the IP!! I'm off to get springs and the removal tool from Rusty - Thx agn - It's all *very* helpful!! Even if this doesn't fix the rocking completely, it appears it's something that needs to be done. LarryT 91 300D Does your business accept or need to accept V/MC/AE/Dis?
