In the near future I will be swapping the 4.0 Inline from my jeep TJ for a ALH VW diesel. I ended up getting two ALH engines from a Kijiji ad, one was suppose to have internal damage and the other one was ready to run. Using a wiring harness from David Marshall I bench tested the "good one" and it ran well. Turning over the "damaged one" by hand I found that the valves hit the pistons with very little rotation. My initial thought was that the valves were sticking since the engine has been sitting for 3+ years, but after watching the valves move I didn't believe that to be true. I took the timing belt off and rotated the crank and cam together until they came back into sync. I used some primitive tooling to lock the cam and injection pump at TDC, and set the crank at TDC using the harmonic balancer markings since I don't have a VW transmission to work with. The engine came to life very easily once I switched the harness over. I will update as I progress.
