The engine was running well throughout the entire trip and since I bought it 30,000 miles ago, it has 157,000 miles on it. The oil pressure and level where okay leading up to when the engine seized up. I think it may be the water pump died. The car is now at the Merc. dealership in Madison WI, my Dad and I are in Chicago, we took the bus from Madison to Chicago. Any ideas what caused the engine to seize, I think the water pump broke.
