Hey guess where does this hose go?

 

According to my 97 4.6l it is connected to the left cylinder bank PCV (positive crankcase ventilation) valve

 

It's a 5.4 and the breather is on the other side. I don't see a place for it to go into the driver side?

 

The hose is a crankcase vent hose. There's a rubber elbow on a port in the DS valve cover and that tube pushes into the rubber elbow. It doesn't go to the pcv valve, that is on the PS and the hose for it comes out the back of the intake.

 

I got it guys thanks. I just couldn't see it because of the screen on the erg tube.
