23670-30140 is supplied as a remanufactured replacement common rail injector. Cross-reference numbers: 23670-30140. Application recorded for this part: Fits Toyota — 1KD. The injector sits at the end of the rail and does the final metering work: it receives fuel already at high pressure and decides both how much enters the cylinder and how well atomised it is. That combination governs power, smoke and fuel consumption more directly than almost any other part on the engine. Symptoms that point to injector wear include hard starting when hot, rough idle, white smoke at start-up or black smoke under load, a sharp knocking from one cylinder, increased fuel consumption and a gradual loss of power. Do a return-flow check before buying anything. Comparing leak-off volumes between cylinders takes minutes, and if one injector returns far more than its neighbours, that single test has answered the question. Before fitting: clean the seat thoroughly, use new copper washers and seals, and torque the clamp to the engine manufacturer’s figure. Replace as a set where possible, and check whether the ECU needs the new units’ classification codes written in afterwards. Our rebuild standard: strip to components, clean, measure against wear limits, replace what is worn, machine back to specification where required, then calibrate and bench-test every unit. Delivery, return flow, opening pressure and leakage are recorded, and units outside specification are not dispatched. Test sheets available on request, and every unit carries a 12-month warranty.
