I need to adjust the valves on my 1983 300SD (Turbo Diesel) Can someone tell me the proper calibration. My mechanic needs the information.

In another matter, my car has a electric heater that maintains the engine warm during the Winter months. How should I use that hearter? Can I keep it plug in for days at a time? Should I just plug it over night? Should I plug it for a few hours before using the car. I need to know this information since Winter is arround the corner.

Thanks
