Injector copper washer: the carbon glues the injector into the head

expensive

The copper washer under the injector is a one-time seal: it is permanently crushed when torqued, so once refitted it can no longer seal. If the seal goes, combustion gas escapes past the injector at over 2000 degrees and over 300 bar, carbonises the engine oil and eats into the seat of the injector. The fault appears at around 150 000 kilometres, but an early failure can also be caused by incorrect torque, a dirty seat and a reused washer.

The escaping gas mixes the unburnt hydrocarbons with the engine oil under the rocker cover, and a hard, coal-like crust bakes out of that. This deposit surrounds the injector and over time glues it into the cylinder head.

The symptoms are easy to recognise. At idle a rhythmic chuffing noise is audible, one per combustion event. A diesel smell comes from the engine bay, and through the ventilation into the cabin as well. Black, oily deposits are visible at the base of the injector. The engine oil becomes diluted with fuel, and whitish-blue smoke can appear too.

If things are taken past this point, the carbon literally welds the injector into place, and a dedicated injector puller or a slide hammer is needed to get it out. Prying damages the body of the injector. If the seat has already been eaten away, the cylinder head has to be machined or replaced.

The quality of the repair decides matters here. A new copper washer is needed, the old one can never be reused, the seat has to be cleaned with a hand-turned seat cutter, and the torque has to follow the factory figure. Cleaning the seat is the most important step and the one most often done wrong. If one injector needs replacing, typically all four do, because their state of wear is similar, and a new one alongside worn ones does not give the right metering.

above 150,000 km

What to check

  • Listen at idle: a rhythmic chuffing noise means a leaking copper washer
  • Look at the base of the injectors: black, oily, hard deposits belong here
  • Smell the cabin and the engine bay: a diesel smell points to the same thing

High pressure pump: metal debris throughout the whole system

expensive

The high pressure fuel pump wears from the inside, and metal dust forms in the friction pairs. The debris gets into the system and blocks everything there. The wear is reported above 160 000 kilometres, and the upper limit of the pump's life is around 200 000 kilometres, beyond which an overhaul is needed.

Show the rest

The metal dust travels on to the injectors and destroys those too, so a pump fault easily turns into a repair of the whole injection system: the system has to be flushed and the injectors replaced. The pump can also give up suddenly, even on a motorway, and the engine then stops while driving.

The injectors themselves also give up at around 200 000 kilometres, and their symptoms are easy to recognise. The most characteristic is difficult starting on a warm engine. With it comes damaged atomisation at the nozzle, a back-leak through the worn nozzle which makes starting worse still, and fuel getting into the crankcase and raising the oil level.

That last sign is the one that can be caught on the dipstick: if the oil has risen above MAX and smells of diesel, it belongs to the injection system.

above 160,000 km

What to check

  • Look at the oil on the dipstick: oil risen above MAX and smelling of diesel belongs to the injection system
  • Start it with a warm engine too: difficulty starting warm is the most characteristic symptom
  • Ask for the last fuel filter change and ask whether the filter was checked for metal debris

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
