A few questions about my new E300D (long)

[jbhebert]

I just bought a 1995 E300D to replace my 1982 300CD that was totalled a few weeks ago. I am only really familiar with the OM617 motors, so this is a bit of a new experience for me. Naturally, I have a few questions.

I used to benchmark the state of tune on my 123 chassis cars by doing a couple of 0-60 runs. Something in the 12 second range usually indicated that the car was making appropriate power. What is the expected 0-60 time on the E300D? I have to assume that since it makes similar power and weighs almost the same as my 300CD, it should be similar.

This brings me to my second question. I picked up the car from NC and drove it back to MA, a little over 800 miles. The car drove GREAT but seems to be down a little on power. I will time it at lunch, but it seems to be in the 15 second range for 0-60. It is smooth as heck, and got over 30 MPG doing about 85 MPH for a full tank. It has also been completely dealer maintained, with recent fuel and air filters installed. I have read that on these motors the LOOOOOOOOOOOONG intake can get clogged with soot from the EGR, which can effect performance. Should I pull the intake and give it a good cleaning? The car has 162,000 miles on it and I'm sure it's never been done.

Next question, also related: Is there a Diesel Purge procedure similar to the OM617 motors, where I can run some directly into the motor instead of pouring it into the tank? The intake seems to block easy access to the IP and associated plumbing.

Are there other items that could also affect performance adversely that I should know about? Are there any "sensitive" parts on this motor (read: $$$) that I should be aware of and address? Any recomendations from someone in the know would be most appreciated. I am planning on switching to Mobil 1 Truck & SUV (5W-40) or 0-40 (depending on availability) at my next oil change. This is what I ran in my 300CD and I see no reason why it won't work in this car.

Thanks in advance.
