More than likely a broken rocker arm, but it can also be a broken valve spring.
Both problems can lead to an engine failure, the biggest worry would be the valve spring.
Don't rev the engine it can fail in a second.
I suggest having it trucked to the repair shop and tell them to pull the valve, on the side with the noise cover for a look.
