Putting the finishing touches to this challenging rebuild.

Another challenging engine rebuild underway in the CJ machine shop. This engine was in extremely poor condition, despite supposedly having very few miles on a substantial rebuild. The water jackets and coolant passageways were as blocked as you are ever likely to see in an XK engine. There was significant damage to almost every bearing and journal, the camshafts required extensive repairs, the cam caps were out of alignment and the main caps were in urgent need of an align hone.
