I don't know if I should be congratulated or scolded. I just bought an '80 240D that was not really represented well on ebay. Don't get me wrong, the car is nice....just a few concerns:

1) The car has about 8-10 inches of blow-by when cap is taken off. It also "mists" a little bit of oil on top of valve-cover when cap is off....but nothing that a paper towel or two can't clean up without it being a real mess. Is this a sign the engine is worn out or is this normal blow-by?

2) The car has always been in Calif. and has no rust. However, the real window seal leaks just a wee bit. After a hard rain I noticed that there were a few drops in the trunk and that the carpet by the back window was a little damp. I looked at the seal and it is cracked in a bunch of places. I called around and was quoted $150 for the repair. Any tips on repairing the window? Is this normal on these cars?

3) The cruise does not work. But, the car holds vacuum (locks continue to work) after car has not be started for a few days. Any ideas?

4) The AC won't kick on. I think the freon is so low that the compressor won't engage. Has anyone converted their GM style compressor to R134 with any luck? I think I should replace all parts (except probably the evaporator...too hard to change...I would think) if I try to convert over to R134. Any suggestions?

5) I have a diesel leak on the outside of the injector that is closest to the firewall. Upon close inspection it looks like the "braided" lines made out of some type of fabric are soaked in diesel? Do these leak a lot? Easy to replace? Does the injector have a rubber seal or something that might need to be replaced to stop leaking?

6)Brakes squeek when pressing on brake pedal ONLY when car is traveling in reverse? Any ideas?

7)This is the BIG CONCERN that I really need some expert advice on: It is a manual trans car and I noticed that around the trans housing that a few dropplets of oil accumulate there and probably 3 or 4 good size drops hit the ground after I drive the car. The valve cover is not leaking at all.....so is this the rear main seal going bad? Do I need to get this changed righ away or is this nothing to worry about? Everything else under the car is dry except for this area. What do you think it would/should cost to repair? I don't want the clutch to start slipping because it is oil soaked.

Ok, sorry for all the questions....I really appreciate everyones time they give in their replys. I have not serviced the car yet and have some basic questions that would aid me in a few areas of routine maintenance:

1) how many quarts of oil does it take?
2) Type of antifreeze I should use in car?
3) Type of man. tran fluid?
4) Type of power steering fluid?
5) Any fittings that need to be greased or are they all sealed?
6) I have read that the valves should be adjusted every 15k, besides getting the special wrenches is there anything else I should know/do when performing this job? Does anyone use any sealant when putting on a new valve cover gasket?
7) Any tricks to getting system primed once the two fuel filters are changed?

The car is almost perfect on the inside. I mean this thing looks brand new. It has only one small crack in the dash and the seats are like new. The only thing that needs attention as far as the upholstery is some cloth around the door on the driver and passenger side....nothing major though.

Car has 240k on it....not sure if the engine has been rebuilt though. I can do 55 going up a very long 7% grade in third gear and temp gauge does not move much. I think it is a pretty good car....maybe I did ok....maybe I didn't. Your feedback is much appreciated.
