So could you explain a little more how you fixed it? Did the head need to come off or did you just install it back into place?
Installed in place. Only tools you really need is a 10mm wrench, 10mm socket and a few Extensions. This is for drivers side.
1) disconnect battery
2) pull inner wheel well
3) Now you can get to three of the four bolts pretty easy.
4) now remove the catalytic converter heat shield. One bolt is accessed through the wheel well, the second from under the jeep.
The final bolt is really fun [emoji57]this is where the box end wrench comes in. Also this last bolt has to be the last one out and first one in.
What I did was hang the gasket from the upper bolts to start the tricky one by hand. Once it's started get the other three in and started. I put anti-seize on bolts.
Snug up all four bolts.
I did a X pattern to tighten I believe torque is 217 in lb (44ish ft lb)
I then started the jeep let in run for about 15 minutes, and rechecked the torque.
Then reinstalled heat shield and inner wheel well done deal
Sorry now pictures of reinstall some of this is a bit of a balancing act in tight spaces.
