Have an intermittent rattling noise coming from low down on the cambelt side of the engine, can be heard at its loudest through the drivers side wheel arch.
If the aircon is off, no noise, if the aircon is on, can be heard when the engine has warmed up. Wrongly diagnosed by myself and a local indie, who I trust, as a worn clutch or input shaft bearing on the a/c compressor which was replaced yesterday. The old compressor did have excessive play in the shaft bearing, so needed replacing anyway BUT the rattling noise persists.
I am thinking may be the noise is being caused by the extra load being put on the v belt when a/c is on so thought of the v belt tensioner but no noise coming from there and as said previously, it's coming from low down. Is it possible that the vibration damper could be going? Don't know how this is constructed internally so haven't got the knowledge to think this one through.
Any help would be greatly appreciated as it's not the time of year to be running without a/c!
