Hi. I'm picking up my 1997 E300D on Thursday. My 5th M-B ever (230SL, 450SL, E420, C230), first diesel.

In another thread, a few recommendations were made regarding what I should do proactively to improve my chances at enjoyable and reliable motoring. I'm starting this thread to focus on the topic.

Do right away
- Change the seal where the wiring harness enters the transmission.
- Check for biodegarded wiring insulation in engine harness, behind headlights, and anywhere else you have access to wires while working on other projects.
- Block ERG connection. (I know recycling gasses can clog up intake, but I would like to hear more about benefits and detriments to this.)
- Remove and clean intake manifold.
- Check for cracks/leaks in the 12 plastic crankcase vent lines going into each intake runner.

Do when you have time, money, or a reason
- Upgrade alternator to something in the 115 to 150 amp range.


Looking forward to all your sage advice!
