Valve Cover Troubles

I was in the process of removing the valve cover to replace the valve cover gasket and adjust the rocker arms when I discovered the rear end of the valve cover couldn't be lifted up. The front end came off fine. It wobbles around in the rear, but seems to be stuck somehow. I don't know if the rocker arms are blocking the upward movement of the valve cover or what it is. Has anyone else run into this problem? Any help would be greatly appreciated. Thanks!

That was my thought also, I missed it the first time when I did mine.

How do I get to the rear bolt? It seems to be buried under the firewall...

Unfamiliar w/ I6 but when we had the Duster there were fitment "issues" that we resolved by drilling 2" holes in the firewall (we did floorpan and other locations) and putting plastic snap-in caps back in the hole. Can you get to the area w/ a drill from under the firewall? Be nice if you ever had to do it again.
All else fails, can you unbolt the motor support brackets from the frame and lower the motor enough to do the job, then lift it back up and rebolt.
Both ideas are sorta extreme but you are at a point where you now HAVE to do something.

If it's good TO you, it's gotta be good FOR you....

When I removed my valve cover for the first time a couple weeks ago it did the same thing, that is until it finally came off with a broken hole and a bolt still in the head near the fire wall. I even looked for a bolt back there and still didn't see it. I installed an aluminum valve cover and had to unbolt and jack up the tranny to make enough room between the fire wall and valve cover for a long allen wrench to tighten the new bolt. It was 5 minutes well spent. You may need to do that to get the bolt out.

Either your mounts are soft and allowed the engine to slide back or the tub is too far forward. Either way, that cover is warped big time and needs to visit the dumpster. The metal cover are the way to go for leakage control.

Agreed about the need for a metal valve cover. Another thing that would cause the valve cover to be so close to the firewall is a transfer case lowering kit. That's the issue in my case.

Yep, my friends CJ had the same problem trying to get access to the rear valve cover bolt. It's a 1/4-20 bolt by the way.

He had a transfer case lowering kit installed so we had to remove the two bolts holding the trans mount to the cross member and jacked the the bottom end of the transfer case upward with a short 2x4 block of wood. Avoid lifting the transfer case up by the tail housing or you may damage it.

X2 on everyone stating that you have to jack up the tranny. it looks like your motor is pushed all the way back against the firewall. i would drop the skidplate, jack up the tranny, do the valve cover and also do the motor mounts. good luck

Dropping skidplate would just be extra work in my opinion. Remove 2 nuts and washers from tranny mount, put floor jack and block of wood under tranny and jack it up slowly. 5 minutes.

I was able to remove the old plastic cover, although I wasn't able to do it without breaking it! Lol. You can see a piece of it in the top right of the pic. You can see the previous owner got that blue gasket sealant all over the place! Anyway, I already bought a black replacement aluminum valve cover kit by Crown at Off Road Motorsports here in town. Thanks for all the advice!
