Ford Mondeo BA7

1.6 Duratorq TDCi 85 kW/115 hp PSA engine, Mondeo III facelift

• !! Injector Seal 'Black Death' Failure from 100,000 km

  The copper sealing washers at the injector seat fail and allow soot to enter the engine oil. The soot blocks the mesh filter in the turbo oil feed. This is the primary cause of turbocharger damage on this engine. Replacing all injector seals is a known maintenance item.

  Symptoms: Diesel smell inside the cabin, black deposits around injectors, smoke from the engine bay, subsequent turbocharger damage

• !! Turbocharger Failure from Oil Starvation from 130,000 km

  Soot from leaking injector seals blocks the fine mesh filter in the turbo oil feed (banjo bolt). Below 0.8 bar oil pressure the turbocharger fails. A complete repair includes the turbo, oil sump, oil strainer, oil filter housing and intercooler. Costs run to £1,300–£2,200.

  Symptoms: Whistling from the turbo area, power loss, blue smoke clouds, oil in the intake tract

• !! Leaking injector seals from 130,000 km

  The flame discs and O-ring seals on the injectors burn through, allowing combustion gases and fuel to escape into the cam cover area. Leads to hardened oil deposits.

  Symptoms: Diesel smell in the engine bay, oily grime around the cam cover, rough idle, visible smoke from the crankcase breather.

• !! Injector seal: "Black Death" failure from 120,000 km

  The copper sealing washers at the injector seat fail under pressure and heat. Combustion gases blow past the injector and bake black, tar-like carbon onto the injector boss. Seized injectors require specialist tools for removal; the cylinder head sealing face can be damaged.

  Symptoms: Black deposits around injectors, diesel smell, rough running, cylinder pressure loss
