Is your common rail diesel causing problems

Injector blow by can be the cause of many problems on Common Rail Diesel engines. Bad starting, uneven, smokey tick over, lumpy running, hesitation on acceleration and black deposits around the injectors are all an indication that the diesel injectors need to be re-seated or replaced.

Eventually these problems will affect the vehicles' ECU and cause over fuelling of the cylinder head.

Even after the diesel injector is removed, cleaned and a new copper washer fitted it may not always rectify the problem. Often the seat of the injector has been damaged due to constant erosion from escaping combustion gases.

The only way is to resolve this is to reface the injector seat.

This new Diesel Injector Cutter Set for BMW, Mercedes, Citroen, Peugeot and Renault comes complete with Centring Pilot, T Handled Driver and four cutters in 19mm (Flat and angled) 17mm and 15mm. Blow mould storage case keeps the kit together.
