Just curious the two pics of the passengers side rear rocker cover is there a hose missing from there ? It just has a small push on rubber plug on it.

The pic below of the throttle body , what does the hose outlined in red do that runs to the intake manifold ? Also is the other hose going into the throttle body from the pcv ?

Thanks

The hose you’ve highlighted is the crankcase breather (pcv) hose and the passenger side rocker cover breather is normally blanked off like that it’s only the drivers side that’s connected which is what the other hose is connected to the inlet manifold

Normally the left and right rear pcv ports merge into each other on the driver's side then run into the manifold. The drivers side front port is the PCV system intake from the throttle body

This kind of gives you the idea

Thanks vr 304 , so the other hose on the throttle body not highlighted is the hose you would use for a catch can ?
