Water pump burp?? Need help!
The water pump on my stock 94 vert (39K miles) did something weird yesterday... and I'm terrified that it's going to destroy the Opti. I just bought the car, it ran great for the 250-mile drive home, sat in the garage overnight, no engine leaks of any kind. Then, yesterday, I started up the engine (from cold) and revved it a little (not over 2000 rpm) showing it to a friend, then shut it down. About 2-3 ounces of coolant appeared on the floor, and I traced it back up to the bottom of the water pump. After agonizing about it overnight, I started the engine today, let it run for 15 minutes... and everything stays completely dry.
Any ideas? I though a leaking water pump would leak all the time... was it something to do with revving, then shutting down? Some kind of pressure relief?... If I've got a leaker, I need to replace it immediately, not wait for the Opti to get trashed, right?

Replace the pump, it is bad.
First the seal will fail (leaking coolant), then coolant will then destroy the bearings.
I replaced one on an F-Body last weekend. Not a bad job, just messy.
