Diesel noise like a slinky - What??

Did you ever play with one of those old metal slinky toys when you were a kid? Do you remember that metalic sound they would make as they wound their way down a set of stairs? Well my 126 makes a similar type noise when I begin to accelerate and then again as the car slows down. I'm new to this so I thought I would consult the experts. Does anyone know what that noise is? Is it a huge problem? How do I fix it? Thanks. Rick

Biodiesel engine noise, sluggish?

After installing a screen in my tank (it was missing and a large outlet pipe installed) my engine seemed noisier. Is this injecter pump noise? Now the car is loosing power after two days on biodiesel. The prefilter looks clean. Is my main filter clogging up already?

Valve adjustment sounds

I just did a valve adjustment on my 80 300SD. None of the valves had enough clearance when I started so they were all adjusted following your guide and using your valve adjustment tools. I got everything back together and the engine started fine, actually it seems to fire up a bit more quickly.

Gas engine MBZ oil change recommendation

I know that the oil is supposed to be changed every 3k miles on an MBZ diesel. I'm wondering if there is a time deadline as well like on a gas car -- say after 3 months even if the car hasn't been driven much? Thanks, B

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.
