Also there is a 2x4 black box connected to wire. What are they for? They look like there should be a hose connected to it.

Ranger should I put my cover back on and start it for and while and shut it down and take the cover off?
BTW the dealer discontinue the T30 bolts for the cover of 93-94
Remember, the PCV pulls crankcase gasses into the manifold and burns them. When you shut down, those gasses settle in the manifold. I suspect that is what you are seeing. Perfectly normal and it takes years to accumulate. Wipe it out and drive it for a few days. Then recheck it. I doubt you'll see any build up that soon.
