"clack" sound when starting my '82 240D
last time when i started my car, it made one "clack" sound and then started just fine. just one clack. it sounded like metal hitting metal. it was about 55 degrees out. car doesn't burn much oil or leak oil. smokes a little but not real noticeable.
cold starting- i have a MB cold starting guide that talks about holding your pedal all the way down and crank the engine that way. even though 55 is not cold, i thought i try it. i think this sound usually happens when i try this method. tried it 2 or 3 times only. normally, the initial start, the car cranks about 4 seconds, one or two cylinders fire up, keep cranking, and then the rest. i think that is normal. what could it be ? valves hitting something ? something to worry about ? i've owned the car 2400 miles and so far its starts and runs great.

Air Cleaner
My guess would be your air cleaner clanking once against the valve cover.
Hold the air cleaner and have an assistant start the car. I bet that makes it go away.

[QUOTE=centroid1;1488982]this sound is a solid sound, like a hammer hitting a piece of metal. the air cleaner, would'nt that be more of a sheet metal rattle sound ?
[QUOTE] You'd be suprised...mine were pretty loud upon startup and shutdown.

You can replace them all if you want to know their status, I normally just replace them as they fail. Do you know how to test their resistance? I also use bosch GPs.
