Timing chain on a 420 SEL

Hello friends,
I recently bought a very nice MB 420 SEL which had only 87K. It's in mint condition. I have 90K miles on it now. My major concern is replacing the timing chain. As many people say, I don't get a clacking noise when I change the oil. However, when I start it in sub zero temperatures, I do hear a clacking noise upon start for about 2-3 seconds. Is that noise coming from head lifters due to not getting oil at startup or the Timing chain slapping? Please advice.
