After discovering the broken bolt on the passenger side exhaust manifold I decided to go ahead and make the proper repairs. After removing the passenger side manifold I was greeted by a welcome surprise! The bolt was not broken into the block like the drivers side. There was still some of the bolt sticking out for me to grab. Using a pair of vice grips I was able to loosen it and even remove it by hand.
What We Discovered Next
The exhaust manifold on the passenger side also had a crack. It wasn't as bad as the other side but we decided to replace it. Having gone this far it only made sense to complete the work properly. The crack wasn't the only issue we found though. I noticed the rear spark plug had quite a bit of oil on it. After closer inspection I found the valve cover gasket was leaking. It only made sense to repair that as well. Upon removal of the valve cover I was unable to simply remove the gasket. It had solidified along the bottom edge and cracked into pieces. I had to dig out all the hardened rubber in preparation for the new gasket.
Getting the Parts
Summit Racing again provided the replacement exhaust manifold. I already had new bolts from the kit from the driver side replacement. The valve cover gasket came from Autozone. Then came the next problem. No auto store anywhere local had the manifold gasket. Summit could get the part but it would have been a month before it arrived. We had to order it from Amazon at a higher cost but it would arrive within 5 days.
Installing the Parts
It only took a couple hours to reinstall the new parts. Once again the Jeep is ready to go. We'll take it out a couple times before our next off road adventure to make sure there were no issues with the install. The picture below is of the completed driver side install. I couldn't get the camera on the passenger side manifold for a final picture due to lack of space but it looks essentially the same.
