My 2000 Ford F150 overheated, so today I was putting water radiator and water was coming through the PCV hose coming of my valve covers. Why is that, and now my motor wont turn over.

Sounds like you have a cracked head or blown head gasket. Also sounds like one or more of the cylinders has coolant in it. This is why the engine won't turn over. It's hydrostaticly locked. Coolant can not be compressed so henceforth the engine will not crank over. To prove this, remove all the spark plugs and then try cranking the engine. You'll see coolant squirt out of the spark plug holes of the effected cylinders as the engine cranks over. HTH. -Jim


Sounds like the head is not only cracked, but severely cracked. If the process of placing water in the radiator fills up the inside of the valve cover to the point it drips out of the PCV valve connection, the engine is shot.
