I noticed some dry coolant on the air intake before the throttle body tonight and took a good look with the engine running and noticed the odd droplet of coolant spraying out behind the water pump pulley and decided I'd change the pump on Saturday, I thought a couple of days and take it easy on the revs and it should be ok.
Anyway I was almost home and at 1,500rpm the entire water pump bearing gave way, there was nothing left resulting in 20mm of play on the water pump pulley, the fan of course hit the radiator and had 2 blades left by the time I stopped and most of the coolant went out through the front of the water pump.
So to fellow M60 owners if there is any leak at all from the water pump change it a.s.a.p
