Yeah the head replacement was a bit unusual for a 1kd but I was towing a trailer and the engine light came on so I stopped straight away, result was a split tank on the radiator and the head was leaking from the combustion chamber to the water jacket on cylinder three. I put a new head on using the original injectors ( these had been fitted new at 200,000 and tested fine. one problem though was when the fuel rail came off the wires got pulled out the plug on the pressure regulating valve. I repaired this as Toyota denied the little harness existed. The car has been running fine all be it with the pump a bit noisy but recently has come up with injector knock when when backing off and now also when accelerating. Baileys Diesel say if the pressure regulating valve uis crook it will come up with a code but I have no codes present. I just checked the injectors and they all tested 1.0 ohms. Going to do a pilot value relearn on the new SCV today and see what happens. Also checking for a suction air leak from tank to filter just in case
