I finally got my Jeep back yesterday and all engine issues have been fixed. They ended up replacing the rocker arm, pedistools on drivers side cylinders, replaced all lifters and head gaskets. Noise went away, but best of all, the Jeep feels a lot more peppy. I don't know if is was missing air hose and lose of pressure and/or the recent mechanical problems but now the engine feels like a V8. Before it felt like a slightly more robust V6, but not by much. This is my first V8 car so I was probably ignorant and didn't know any better. Now I feel the difference.
Glad to hear it. Keep all records in case anything down the road happens but hopefully you won't ever need them.
