Hi All

The following is written in full acknowledgement that its difficult to accurately communicate the nature of engine noises through the medium of the typed word. ;0)

Since having the cambelt replaced last July I've noticed an unusual noise on start up from cold. Its a sort of "whoop-whoop" sound, with the whoops timed to each rotation of the auxiliary belts. Its obvious when the car is parked and the bonnet lifted, but I can only hear it when driving if the engine is ticking over at a standstill. Until recently it only lasted till the engine warmed up; now it becomes apparent once the engine is warm and doesn't go away.

I was originally told that the noise was from a drivebelt, so I squirted all manner of rubbish on the belts but without success. Further research confirmed that it was never likely to be caused by a belt.

Today I've had the belts replaced (because they were of an age when it was advisable) but the noise is still there and I've now been told that its likely to be caused by dry bearings on the water pump.

Does that sound feasible? If so, does the noise indicate imminent failure of the pump?
