A friend of mine purchased an 03 450 and had been setting torn down for kick idle gear replacement. Someone told him to check some seal in the cooling system that can go bad after a time when setting up. Does anybody know what the guy may be talking about? The only thing I could think of is the water pump...but I've never let mine set up so havent had this problem.

Has to be the coolant seal on the impeller shaft. It won't hurt to replace it, and it could be quite annoying if you don't.
