'06 TJ 4.0L Valve Cover Removal

How do I remove the bolt in the rear driver's side that looks like it has part of the wiring loom for the fuel injectors mounted to it? It looks like it has a small nut below where the wiring loom attaches but I'm having trouble getting a wrench on it. Am I doing something wrong??

Re-posting: '06 TJ Valve Cover Removal

Hello all,

New poster here. Like the OP, my "new to me" 2006 TJ leaks oil from the rear driver's side corner of the valve cover. A wiring loom attaches to the top of the corner stud/ bolt (and maybe at another location between the head and firewall) and blocks access to the bolt. I can try to post a photo of it would be helpful.

I didn't find a reply to the original post and hope a more experienced jeeper, or anyone with a shop manual , can offer advice to a newb.

Thanks!

Thanks for the encouragement, RubiBlue.

Finding the "appropriate socket" is the rub. The loom is attached to the top of the stud with an odd type of fastener. Not a hex nut or a slotted screw and I'll need to take it off before I can get a socket onto the valve cover hex nut. The loom may also be attached at another location that I can't see.

I think I'll start another thread with a photo of the fastener asking "What is this and how do I take it off???".

Thanks again.

Sorry man its been a while since I had it off so I dont remember the size. I remember it being a real PITA but I eventually got it. I believe mine was a hex nut on top but I could be remembering it wrong, good luck you will get it.

I just replaced the valve cover gasket on my 99. On mine it was a ground strap in the same spot 18 or 17 mm. I didn't take it off just loosened it up enough to lift the valve passed it. It had a big washer on it under the nut holding the valve cover on. I don't know if the 2000's and up are different.

Did anyone figure out how to get the wire harness bridge off? It feels like a plastic cap is over the bolt/stud.

I just completed this on my 2004 LJ last night. the little clip should just slide up the stud. Its like to a body fastener that will push on an off. if you can pull the harness up a little then push the harness back down it will remain higher on the stud. Then you can spin it like a nut with your fingers and it should spin off easy. I had to pull the air duct behind that harness to get some room to shove the harness back far enough to slide the valve cover out. It made it much easier. Hope that helps.

I've got a 2004, Got the valve cover off last night, but the rear wire loom, with the plastic housing was a real pain in the arse. I'm going to try rooming the air duct like in the previous post to give me more room to get it back on. I also had to remove the nut and rear ground strap to get it off......

The plastic wire loom that is similar to a horse shoe shape can be pried up with a couple of screwdrivers, after you remove the nut on top. Use a small screwdriver to open the cover so that you can have more room, mine was so tight that it would not lift up at all until I split it at the snap seam.
