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

87 300TD shifting and acceleration issues

Hi, I'm new to the forum and have enjoyed reading the info posted. I have a 87 300TD with some shifting and acceleration issues. The transmission seems to upshift too rapidly during acceleration and as a result it enters 4th gear by the time I am at about 30 mph. The acceleration from 30 mph on up is very slow. Also, it does not do hills very well at all, even on a minor grade it will only do 45-50 mph and on steep grades it is even worse. Could the turbo be malfunctioning? Is there an easy test for turbo functionality? Could compression account for the problem? On flat roads the car cruises at 80 mph like a champ. Should I get the vacuum tested for the shifting issue?

126 power window failure - whats wrong?

I got a 1983 280se all back and driver windows do not work, only the front on the passenger side. I was wondering if it could be a switch problem and not the window motor since there is no sound coming out of the doors when you hit the windows switch? also, i would like to change the panel where the window switches are because the wood looks deteriorated, any instructions on that? any suggestions will be of great help, this is the first time i put myself up to fixing a car so i will appreciate input. Thanks

HELP!!! 82 300SD Oil Pressure

I need some help in a bad way. I have a 300SD and the oil pressure gage is doing strange things. Once the car warms up and I am under power, say more that 1500 rpms the oil pressure gage will just drop to zero. If I let off the throttle and slow the car down the gage then will immediately peg to 3 then come down to between 1 1/2 and 2 at idle like it should. I only have this problem once the car warms up and when the gage drops from 3 to zero it is like someone just flips a switch and then also the gage will just jump around sometimes. My question is do I have the oil pressure sender failing or is my oil pump failing?

Where the hood hinge goes through the body.....

of my 300TD, the hole has been elongated to the point that the clip pops off the hinge arm when I open the hood. Right now, I have the hinge arm through the hole with a big washer and then the clip. The washer keeps things in place enough to keep the clip on and it works. Certainly not a long term fix. Has anyone dreamed up a solid fix for this one? I thought about JB Welding the washer into place, and then I thought again....Any suggestions, sarcastic or otherwise, are welcome. Thanks!
