Rattling noise from engine

Engine is a standard 2.0 litre in a 1995 900S which has 241.000 km on its back. When the engine is running at idle there is a constant low rattling sound. When accelerating the noise increases with rpm, but when working the engine hard between certain rpm's(for example up a steep hill in second gear) the rattle increases sharply, disappearing as soon as the upper rpm threshold is reached.
I've read about the timing chain rattle but don't consider it a possibility as that noise is supposed to be constant through rpms and have changing characteristics with the engine temperature. I've checked the serpentine belt and it's rollers, all rotate smoothly.
A friend of mine once borrowed a 2002 9-3 convertible with basically the same engine as mine. I noticed it had exactly the same noise but at much lower (and more acceptable) volume. Could my problem simply be a symptom of all the kilometres my car has clocked?
Thanks in advance for your input, regards
