4.7 crankcase breather install
 
I have removed and reinstalled a 4.7 engine in a 2001 Grand Cherokee. I got a couple of new crankcase breathers since the old ones were broken. These are the ones that stick up almost vertical on the back of each cylinder head. I put the left breather in, no problem, but on the right side there's a great big bundle of wires directly over the breather hole leaving no room to install the breather. I'm wondering if the wiring got routed wrong during engine install, but I don't see how else it could go. It has the fuel injector and ignition connectors on it, and they are all where they need to be. Anyone got a picture?

II went outside and took some pics of my 04 4.7HO, but I am a new member and evidently I am not allowed to upload pics yet.

I just changed out my Passenger Side Valve Cover gasket. This photo shows the CCV I believe you're referring to.
The cable you see just above the lower right connector houses the coil and fuel injector wiring.
If I were you, I would disconnect all coil and fuel injector connections, dislodge the wiring loom from the valve cover studs (I believe 2 ea studs), maneuver the cable above the valve cover and into a position near the rear of the valve cover resembling this photo.
Perhaps this will open up the CCV > head path.

Well, I got it in. Had to simultaneously use a ratchet strap and a prybar to hold the wiring out of the way. :)

Yours looks slightly different than mine. My CCV is ALL the way at the back behind the valve cover. Interesting.
