Does everyone get this on their 8V engines? I recently checked my timing belts and they seemed a little loose (worn themselves in since the rebuild) so I thought I would tension them up a bit. I tensioned them up to what the manual recommends and they made a heck of a racket, especially at about 1000rpm and a whine was detectable at speed once warm, which sounded cool
but probably wasnt helping my belts (engine expanded = tightened belts = whine) so I loosened them off slightly and the noise has almost gone, still a slight hum at ~1000rpm. I figured if I loosen them off a little to what the manual says, as the engine gets hot (and expands) an acceptable tension should be reached.
