Thanks for your input. How much did it cost to replace the engine, if you don't mind me asking.you just got unlucky, the 102 hp (CXGB) engine, from my point of view, is pretty resilient.
I have bough a second-hand van with ~270k miles on it and drove it for another ~20k miles until my injectors failed (original ones from factory) and decided it was more feasible to swap the whole engine.
