Hello, I recently got done with changing the head gasket on my 1989 renix jeep, along with the head gasket i also changed the head bolts, valve cover gasket, exhaust and intake manifold gasket, egr gasket, throttle body gasket and I also put in a new O2 sensor because the last one was shot.
Now when starting it up I can hear squaking coming from the valvetrain (it's shouldn't be the serpentine belt because i put in a new idler pulley and a new serpentine belt and when putting water on it, it didn't stop squaking)
The idle is also super rough
There looks to be black soot coming from the exhaust pipe in the back
There is also some kind of smoke coming from the engine near the exhaust manifold.
I have Nick's R.E.M and that shows me I have a loop fault running rich (i had hoped this would go away after I replace the O2 sensor but it didn't)

Below I've attached videos of the engine running and a picture of where I run a ground.

EDIT: I took the valve cover off and I see that it's not getting oil, added a video about it too
EDIT2: Looks like oil isn't getting through the pushrods, the ends of them are gunked up and even when cleaning them they instantly get gunked up again

 

For the running rich part, did you inspect the hose that goes to the MAP sensor? Is it even connected?

 

The map sensor is connected but the vacuum line that goes from the sensor to the throttle body is broken near the throttle body.
Looks like I need a new line + a way to get the tiny chunk out of there.

 

It's just "rubber" grommet that's hardened over the years. You should be able to pick it out.

Here's an improvement to the connection. You'll need to take the TB off. Just as well to ensure you get all the pieces out.

Thanks, got any tips on how to get a stripped torx out? I accidentally stripped one of the torx bolts that hold the TB in..

 

they sit a bit "proud" of the TB top. channel-Loks?
