Can a leaking head gasket cause damage to the water pump? Cause this is the story I heard today from the service manager of my local dealership.
FYI, the car had started producing a distinct engine noise at 65K (kilometers, not miles), which the mechanics attributed to a water pump going bad. They replaced the pump and timing belt while at it.
But is their theory plausible? Also, I know about the oil in coolant and coolant in oil symptoms when a head gasket blows. But can the leak be actually visible, such as a valve cover gasket one?
Thanks,
Nikolas
