Hi everyone! So far this forum has been more helpful to me than a stack of service manuals. But i have one question. My '84 300 D turbo revs at around 3200 RPMs at a steady 70 mph. Is this normal? My trans shifts flawlessly, so I know it's in high gear. (4th). I always thought diesels were not supposed to rev that high. I am planning a couple of 500-600 mile trips in the near future, and I am scared i'm gonna blow up my baby. Any help with this I will really appreciate. Pete Miller.
