Reply to "Valve Stuck Open"

The Reaper (Guest)

I would not assume that the valve is stuck open, but that the valve spring is being held in a compressed position. I would assume there is damage at the other end of the valve; one of two possible problems:

the valve head is partially broken off the stem, hanging to the stem at an angle that holds the valve spring compressed.

the valve head is broken completely off the stem, and while in the process of breaking off the valve stem was bent, which is holding the spring in a compressed position.

The next step is to pull the intake manifold, drain the coolant, and pull that cylinder head to determine the extent of the damage to the engine.
