Did a cambelt \ balance belt \ waterpump change complete with all the bearings a little while ago. Since then there seems to be an increase in belt whine, (Similar sound to the whine of a supercharger belt)

Now I thought the whine could have been down to the new pump bedding in, but its been going on for 150km now.

So the question is, where is the whine coming from? It sounds like its coming from the waterpump area. The belts were all tensioned up to the standard 90 degree twist on the longest run rule.

Doing a long trip next week so would like to be able to cure this, or at least disregard it.

Cheers
