Default What the heck??!! Bad valve?

I pulled the intake manifold off, to pull the head. I thought why not start it with it off.

Here is a video of the result.

I guess it it is. If so why doesn't the other port do the same? Plus I have a bad cyl #3. (not sure if it's rings or valve.)

To me it doesn't look right. Mind you, I know nothing about diesel engines.

Here is a 6.5l, running without intake.
