Recently my W124 wagon started making an odd ticking noise. However it only occurs when the engine is running above 3000 rpm. When driving or idling the car will only tick when above 3000 rpm.

I have had numerous distributor and rotor problems. Could this be the cause? The noise sounds as though it is coming from that part of the engine.

Thanks
Dan
