Confusion
On my vehicle, the PCV valve is on the passenger side valve cover, closest to the firewall. It is connected to a short metal hose that has 2" pieces of rubber on each end. This metal hose then connects to one of the larger aluminum hoses amongst the supercharger plumbing.. about in the middle of the engine bay very close to the firewall.
The small rubber hose (3/8"?) coming off of the bottom of my black plastic air intake tube (from the airbox) runs underneath the supercharger, to the driver's side valve cover. It connects to a black plastic elbow which is at the front (closest to headlights) of the valve cover. What is this device if the other is a PCV? The other is a PCV, as I changed it with a new unit from the original Motorcraft. Could this be another PCV? To my knowledge, EGR valves did not exist on the '93s.
Thanks for clearing this up!
