The engine is rebuildable...it uses loose wet sleeve cylinders so if a piston seizes then that piston and wet sleeve can be replaced.
The biggest concern is the rubber camshaft belt...this has to be replaced at 100,000 mile or major expense occurs!
use only a fully synthetic oil such as shell Helix 40W50 or lower if in a cold climate and the fuel filter needs to be changed on a regular basis.
The black CAC hoses going to and from the intercooler up front are known to split so the best replacements are Silicone hose from SAMCO.
There are lots of maintenance issues that need to be seen to to keep this engine going...fuel filter heads on USA models are bad and the EGR needs to be disabled.
Best thing to do is to go to the CRD Love the Torque section at: http://www.lostjeeps.com/forum
They have a lively CRD community there, read the SAMS Noob guide and ask all your questions there!
