my engine had a whistle across the rev range... i to it to an alfa indy in london who took the belts of and found it was the balance belt tensioner!

i really only wanted to find out what it was as it was coming from near the cambelt.

but i ended up having it replaced while they were in there..

ive seen a few people on this forum with whistling noise so i hope this helps!!
