Air Dam removal

I have a 79' 240D and have been doing the maintenance on the sun roof as per the Mercedessource kit. I have found that the air dam has a bit of rust on it and I wanted to remove it and clean/treat it with the anti-rust paint but I am unsure as to the best way to remove this. I am afraid of breaking it if I force it. Does anyone have any sequence of steps used to properly remove the air dam??? Thanks.

1978 300CD losing power after twenty minutes.

I bought a 1978 300CD with 250K miles about two months ago. So many problems and I've never worked on a diesel but my income is too modest to afford a mechanic. I'm just a humble computer guy. Okay, enough blathering. Recently, the power assist on the brakes gave out and, simultaneously, the car wouldn't shut off when I removed the ignition key. I have been told that I need to rebuild the vacuum pump. After a week of manual braking (that thing's a beast to stop) and manually choking the engine when I get to my destination it's developed a new problem that is far more devious.

1984 300TD Fuel Guage Not Working

I just bought an 84 300TD (Yes, the wagon) and I really like it. One thing that I don't like is that the fuel guage is not working. It jumps all over at times, and at other times it will stay all the way empty (after I just filled it up) or all of the way full. Not sure if this is related, but when I fill it up, I have to put fuel in very very slowly (~.5 gal per minute) otherwise the filler fills with foam and shuts the station pump off.

HELP NEEDED WITH CLUTCH PROBLEM!!

Hi there. I have a 300DT Euro with a 4 speed manual. I bought all the clutch related parts to do the job and then decided to have my mechanic do the job.
So we after the installation, all was fine for about 1 week, then the shifting became hard. I took it back and he figured their was some air in the lines still. So he bled the system again, getting a little bit of air out. Then another 2 weeks later, the same thing happened and i took it back again. And now the same thing is happening again.
I don't want to take it back to him again. I trust him and his work, but i would feel wrong in asking him to 'fix it again'. Also, Mercedes are not his specialty, so i am asking for advice from Kent or anyone who has any help to offer.

Black Stuff Blocking Fuel Filters!! 1985 300TD

I have a 1985 300TD converted to run on WVO. It ran great for about a year and then I have been plagued with problems (plugging filters). My oil is liquid gold. I suspected some of the neoprene fuel hose I used was going bad. I drained both tanks ( I have a small diesel tank for starting/purging) and replaced every fuel line and filter. I have been testing the system using diesel only to make sure it all works. I have Kent's little clear filter at the exit of the main (original) tank. It plugs up with what looks like black sand.

1981 300 TD Wagon Transmission doesn't shift

While driving, the trany shifted to nuetral by itself. No position on the gear shift changes the condition. However, when I shift to park I do get a grinding noise before the gears mesh. Every other position is quiet. I was told that I may have to replace the transmission and I am willing to do so as long as a second opinion agrees with the first.

If I do need to replace the transmission, I need a good manual to help out.
