I recently replaced a 1979 240D motor with one from a 1982. The 1982 motor had an EGR valve and assorted plumbing. In discussing the swap with a local Mercedes diesel mechanic he indicated that I could take the intake and exhaust manifold from my 79 motor and install in on the 82 motor to eliminate the EGR system. Well I took his advise and now cannot get the engine to run. The engine was in perfect running condition prior to the swap. Has anyone out their performed such a modification? IF so any advise on how to get the engine to run would be much appreciated. I wasn't too careful in removing the EGR components and would probably have to purchase new hardware.
