Diesel Injector Copper Washers Seal Sealing Rings Kit Ports Assortment 150pcs

Product Information

Torque matters: The clamp bolts are stretch bolts, so correct and accurate tightening is critical. When set, they stretch a set amount, but remain elastic. Torque first to 8Nm.

Often, such problems can be prevented by cleaning the fuel injectors every 25,000 miles. Specialist products such as Wynn’s fuel injector cleaner are available from Halfords, with different versions for petrol and diesel engines. Fit them: Fit each injector (with a new copper washer) into the engine. Locate the clamp over each pair of injectors. This orientates the injectors for spray pattern.Engine abuse:The state of this injector, from a different TDCi Defender, shows why it’s important to maintain the engine in good health. The injector nozzle is coated with carbon and oil, making an efficient fuel spray pattern impossible. This injector hasn’t failed on its own, it’s been destroyed by neglecting other aspects of the engine. Acontemporary diesel engine relies on high-pressure injector technology, and the Puma engine is no different. This Ford in-line four-pot diesel originated in the Duratorq TDCi for the Ford Transit, but it was used by several other manufacturers, including Land Rover in the Defender from 2007. If your vehicle's engine has started misbehaving in certain ways, it may need replacement fuel injectors. At Halfords, we're one of the UK's leading suppliers of all car parts with an extensive selection available online—and at our 600+ Halfords garages nationwide. Feed pipes: Remove the four injector feed pipes. Technically, these should be renewed, being part of the high-pressure system. Close inspection shows them to be perfect to reuse. Follow the process: Plug is located in the tip hole to prevent dirt ingress. Then helical brush (inset), spinning in drill, cleans the sides of the injector bores in the head.

Are they loose?Remove injector clamp bolts and clamps. These are stretch bolts, so single use. They can stretch further over time, allowing the injector to ‘chatter’ under the clamp. Code work: Using general diagnostic software, code the injectors to the car. You need to input the four unique codes for the injectors. You did write those down, didn’t you? Seals and washers play a crucial role in the correct running of high-pressure systems. For instance; with every new injector kit you will have a soft copper washer - actually, it's a high-pressure seal.It is possible to recondition the injectors, but results can vary, so consider the value of simply replacing old with new. New injectors need to be coded to the car using diagnostic software via the OBD port. There are two things to be aware of when changing injectors. Carbon deposits can form on injector tips, making their extraction from the head difficult. And the mating seat in the head must be free from dirt and deposits when refitting the new injector. Like all of us working on our Land Rovers, consider carefully if you can cope with either issue. If not, then it might be time to take the car to a specialist. There’s no shame in that: wise enthusiasts understand the limits of their abilities. When fuel injectors are working properly they adjust the amount of fuel being introduced to match the variable airflow. If kept clean and well-maintained, your fuel injectors can also maximise the car's fuel efficiency and minimise pollution. In high-pressure diesel systems the injector has to seat into the seal perfectly, otherwise, a pressure bypass can occur, which will reduce the compression in that cylinder and provide very reduced performance, even when a new injector has been installed. (This will often produce degraded combustion).
