my 1979 ford f-150 pickup makes a clicking noise when it starts and water gets into the engine and the oil leaks all over

 

What year?

On an older truck like that, you need to check your battery, all connections, and battery cables for "clicking". Specifically, if those cables are old, they can look ok, but corrosion can infiltrate down inside the cables. Elaborate on your "water in engine" problem, and you will get better responses.
