Agree, I had the same noise. Turned out to be the alternator. Rebuilt mine for $75.00, water cooled. Not very difficult.

Lol @ them saying thats normal. There is only a matter of time before it seizes up completely if it is the alternator. That sounds similar to how mine did cannot tell from the video but mine was so loud it sounded like the engine was about to blow up. If it is not could also be any other pulley or tensioner or accessory being driven by the belt. I would advise you to take it else where to get checked out

Sounds like ticking valve lifters but it's not fast enough. I'd start with what others are claiming.

I referenced this http://www.meeknet.co.uk/E38/Alternator/Index.htm. http://www.smithcoelectric.com/servl...ngs/Categories has the correct bearings. Give them a call for part numbers

Good Luck

No more than $400.00 labor about $350.00 for a re manufactured alternator. Shop around.

Hi to this date my warranty won't authorize work unless there is a fault code the alternator stops working completely. So I'm stuck with this loud tick. However the car is in for a burst cooling pipe which they are authorizing for repair $2600. Anyone know if that part is in the same area as alternator. I can have them check that if they are in the Same area.
