FAQ

Q1: How do I know if this oil nozzle (8-94469709-3) fits my engine?
A1: This part is specifically designed for the Isuzu 4JB1 diesel engine. To confirm fitment, please check the part number stamped on your existing nozzle. If it matches 8-94469709-3 and your engine is a 4JB1, it will be a direct replacement. If you are unsure, please contact our support team with your engine’s model number and the old part number for verification.

Q2: What are the symptoms of a faulty oil nozzle?
A2: A worn or clogged oil nozzle can cause several performance issues in your 4JB1 engine. Common symptoms include: rough idling, a noticeable loss of engine power, increased fuel consumption, black or white smoke from the exhaust, and difficulty starting the engine. Replacing the nozzle is a standard part of a fuel system overhaul.

Q3: Is this a complete injector unit or just the nozzle tip?
A3: This product is the oil nozzle component, which is the tip of the fuel injector. It is the part that atomizes the fuel. While it is a critical wear item, it is not a complete injector assembly. Installation requires proper cleaning of the injector body and careful handling to avoid contamination. We recommend having this replaced by a qualified diesel technician.
