Noisy start up
I have an 89 300 SL. It goes great but Im a bit concerned about a clatter at start up. The noise only lasts a couple of seconds. It doesn't happen at a warm start but when the car hasnt been used for several hours.
Am I right to be concerned? Any idea's.

sounds like timing chain.. I would get it checked as it can lead to serious damage.. older sl/slc also had a pollution pump that can make some strange noises,, not sure if that is aplicable to your model tho

'81 380SL/dual cam chain-LT4 vette-Z06 ('03) vette-I need a bigger garage....
I switched over to the dual chain conversion on my '81 380 and eliminated the chain rattle on start up. Of course, I also put in a new oil pump. It is my understanding that there is a valve in the oil pump that maintains prime so that the chain tensioner won't release pressure on chain after shutdown. It could have been a problem there, I don't know.
But in any case, you really need to diagnose and repair before the chain jumps and really does damage.
