Body and Interior Specific Aid

w126 1985 380se white smoke exhaust after sitting and cold. white smoke goes away once engine is warmed up. someone told me that this indicates antifreeze in the cylinder. any suggestionws?

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

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.

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
