Smoking diesels usually mean that there is a certain amount of unburnt fuel passing through. 1) The compression pressures are down 2) The injector pump is incorrectly set (especially possible if a new timing belt has been fitted 3) The engine is running cool due to a water thermostat problem 4) The engine oil level is too high. Much could depend on the van's mileage, really!
