Description

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. ED EVANS SAYS: Injectors tend to be forgotten about until there’s an engine running problem and, of course, not all problems are down to injectors. A multitude of other engine defects can affect the state and lifespan of the injectors, so it’s vital to keep the engine correctly maintained and properly used to avoid replacement of these relatively expensive items. Before thinking about replacing injectors, the engine needs to be inspected by a good specialist to confirm the cause of the symptoms, and the full effects. 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.

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. Other problems include: water in the fuel which can cause the injector nozzles to balloon; carbon can build around the injector nozzles; and combustion gas can blow up past the injector body if the copper seal between the injector and cylinder head fails, exacerbated by the injector clamp bolts stretching.

Rough idling with excessive shaking, jerking or vibration when the engine's running but the vehicle isn't moving 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. Fuel injectors often start to cause problems when the nozzles get clogged. Symptoms of a faulty fuel injector include:

Replaced clips: These are the spill pipe locating clips we found missing on our vehicle. They are brittle, and not easy to buy, so do take care with them.Seat repair:When the injector seat in the head is contaminated or damaged, it can be cleaned or refaced by inserting a special cleaning or cutting tool down through the injector opening to re-create a flat, sealable face for the new sealing washers. Where are they?The 2.4 Puma engine bay: like all modern cars, the injectors are hidden under the plastic cover. Two bolts, off it comes, and we can see everything. Cleanliness within the fuel system is critical so, after removing pipes and components, ensure dirt cannot enter the resulting openings. The injector holes in the head also need to be cleaned to prevent dirt dropping into the engine, as explained in the captions. Well shot:The copper sealing washer from the same injector is deformed and eroded on the near side, allowing combustion gas to blow upward over the injector body, and engine oil to leak down into the cylinder. 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).
