Hi new 300d owner

[andmoon]

Well I got my new to me 250K mile 82 turbo this morning.
Of course I have been searching the forums but will ask a few questions here

My speedo seems to read low....what speeds corresponds to 3000rpm in top gear? Either the flow of traffic has slowed or my speedo is off.
The tach doesn't work for first 5 mins after startup...????
Valve cover gasket is leaking in the front...is this just a new/tightening procedure like gas motors or sign of heavy blowby?
The center vents (2 round thingies) won't pass air under any settings...all the other vents and a/c works great....where to look?
One of the jack points has rust...how do you repair?...I want to keep the integrity of the structure and I take it the jacking points need to be pretty strong to hold up the car. What do I do if I need to change a tire?

Thanks and sorry for the repeat questions...I have been reading the forums for a while but now that I have the car I have allowed myself to loose dignity and just ask ask ask

I beileve at 3000rpm I am going 65mph in my diesel.

I had the same problem with my center vents. There is a vacuum operated accuator directly behind them that may have a leak. I was able to test my accuator by pulling the glove box and reaching in and pulling the lines off, but it was a very tight fit. You have to pull the dash out to replace the accuator pod. There is a place that sells the rubber diaphrams in the pods. But you have to take to pods apart, this is how I fix all mine, and they seem to work well. The pods are like $50 each. I replaced all my diaphrams for that much. Here is the site that sells the diphrams. http://www.autoluxmbz.com/ACDI.html
