I have a 2005 LR3 that has recently developed a very piercing whine coming from the engine...doesn't matter if it's in gear or not and it has never felt like the drive train is involved. Said piercing whine seems to originate from the forward driver's side of the engine, maybe a foot down into the bay. I cannot for the life of me find a pulley diagram on Google images for this engine, anybody have any idea what could be the culprit? The A/C and everything works fine, no substantial change in pitch with the A/C compressor clutch engaged or not or hard turns etc. Idler?
