Refresh or Rebuild: One Cooked 4.0

So I think this'll be my last update unless something catastrophic happens, but I've been running this motor for awhile now, including a 1000 mile round-trip x-mas jaunt, fully loaded through the Sierra Nevada's. The Jeep and the motor are keepers. Doesn't burn oil, plenty of power, no smoking, runs and sounds smooth. Like new inside, too. I completely rebuilt the front suspension and steering, plus new tires and wheels makes for an enjoyable driver. Didn't replace any of the rear bushings (just shocks) but I think I'll go ahead and get that done soon, as I can feel the rear axle shift a bit on hard stops.
