Since the photo hosting site from way back started to charge for the site, if you didn't pay then you lost the use so I doubt they will be available....just went to page 1 of the thread, yep the main info has gone, I will see if I still have copies of the diagrams, may not since a lot of years have gone by otherwise you might be able to source the info from the Merc Forum.
If you want to do the mod, then it is easy BUT it would be a waste of time after all these years without a removal and clean of the inlet manifold unless it's had a catch can on it for many years................if you have bought it 2nd hand it may have the EGR Defeat done, if done properly you wouldn't know unless you opened up some of the wiring harness, with my old rig you wouldn't have a clue.
