my mate is after a van and looked at these,but has been warned off them by a bloke we know who works on a lot of vans & 4x4's
he listed quite a lot of faults including headgaskets,water leaking into the injectors which seize into the head so then the heads scrap and the wiring behind the dash failing he did mention other things aswell but cant remember
he said your best going for a transit,there a lot cheaper on parts,but are prone to dual mass flywheels failing but you can buy a kit for £250 that converts back to a normal clutch & flywheel
hope thats some help
