my citreon xsara has developed a high pitch rattle which has got progressively louder. it sounds like its coming from the sump area but doesnt sound like a crank grumble. the turbo still works, the cars not down on power and doesnt use oil. any idea,s please as this car is sound other than the rattle. ps the car has done 122 thousand. cheers rich

It's a long shot but does it have a damped crankshaft pulley?
If so paint a line across it and keep checking to see if the line becomes mis-aligned. If that happens have the pulley replaced before it flings the aux belt into the timing belt and wrecks the engine.
