Water

Took the vette out for a spirited drive, and naturally everyone wants to challenge you; so I decided to just get away. Anyway, the car is smoking from under the hood, but the gauges all indicate within normal operating temperature. When I open the hood there's water everywhere. What could have been the cause of this? I did drive the car hard, but it's an LT4, it's made to be a mover. I recently had a performance cam ( 503) installed, and while the engine was open, the mechanic thought it was best to chnge the waterpump. I still have the old wp, but I'm just grasping at straws here. Please advise, corvette gurus.

Thanks,
Joe B.

First thing I would check would be all of the hoses.

Yes, check the cooling system when under pressure so, you can see where the coolant is coming out from. Also, do a pressure check on the cooling system.

Bingo; pin-hole in the small hose that runs from the passenger side closest to the engine and runs along the fuel rails. Fixed. That's again for the help.
