Jacking Point Problem/Mercedes 300D 1981

Hi--I recently acquired a 1981 300D--upon closer inspection of the underside, I discovered one of the former owners covered up the jacking points with metal (I am guessing to patch for rust). In any event, I am now wondering what options I have for jacking it up seeing as the jacking points are covered. I am working with a floor jack and jack stands--I have worked with trucks before but not a sedan so I am not sure what my options are as how to get around this problem. Any advice on how to go about safely jacking it up would be appreciated, Thanks, Archie

How to Start 300D 1981 (Newbie needs help!)

Just picked up a 1981 300D with 110,000 miles original engine (I hope). At the resellers lot, they had no problem (naturally) starting it many times for me--and I started it also and drove it home--about 35 miles. Had it garaged for about 1 week now and when I went to start it today, I am struggling. The temp. here today is about 50F--cooler by at least 15 degrees than when I purchased it. I am wondering if that is causing me problems. First off though, I am entirely new to starting a diesel, so my initial question has to do with 'how to start' the vehicle properly.

240D speedometer howl

I have a 1981 240D with a speedometer that has recently begun to howl loudly. The speedometer works fine for awhile and then makes a clicking noise and begins to howl. It continues to indicate speed while howling. When I slow down almost to a complete stop, it seems to reset itself and the howling goes away for awhile. I'm thinking maybe the end of the shaft is worn and slightly rounded? Anyone run into this? I think my speedometer is ok since I just had it rebuilt a few months ago. Thanks, Andy

240D Power Antenna Repair

I have a 83 240D Sedan. The power antenna will not go down all the way when I turn off the radio. It tries but gives up after a few seconds. It basically goes from half up to full up but never all the way down. I was wondering how much work it is to remove and/or fix. Or is it something that is not too much $$ to just replace? I'm kind of a mechanical geek and I like all things to work properly just for the joy of it.

Question about testing for engine blow-by

MY HUSBAND AND I BOUGHT SEVERAL OF YOUR BOOKLETS. WE USED YOUR BOOKLET TITLED "Diesel Performance Tuning and Repair" RECENTLY TO TEST A 79 240D AND IT FAILED VIRTUALLY ALL OF YOUR TESTS LISTED UNDER "Quick Inspection Checklist." THANKS VERY MUCH YOU SAVED US LOTS OF MONEY BY HELPING US JUDGE THE WORTHINESS OF THIS POTENTIAL PURCHASE. ANYHOW, MY HUSBAND DID THE TEST WHERE YOU UNSCREW THE CAP ON THE VALVE COVER AND SEE IF IT DANCES AROUND, OR IF SMOKE BLOWS BY, ON OUR GAS CAR. I'M WONDERING IF IT'S A GOOD TEST FOR GAS CARS AS WELL AS DIESELS? THANKS, B
