Servicing Injectors

Recently we had a 4WD towed into our workshop with an issue. This was no ordinary problem as the owner had tried to work on the injectors in his common rail engine.The issue being that the owner had removed his injectors and couldn’t get it running again. He had polished the injector needles and tried getting them back together again. Worse still he had been doing this work in his driveway out of a couple of ice cream containers. What started off as a simple ‘pull out the injectors and clean the needles’ had turned into an expensive nightmare for him. Probably luck had it that he couldn’t get things back together again preventing further damage to other things like his engine. If he had gotten these back together and somehow been lucky enough for the engine to start it could have created an engine failure from incorrectly operating injectors.

In the end we had to install 4 new complete injectors and we recoded these new injectors to match the vehicle’s computer. Whilst common rail injectors can be serviced by Diesel Experts, the success rate and service life of this is still questionable. When things have been pulled apart and bits are missing its even worse. For now, we still state that generally a modern common rail Diesel injector lasts a few hundred thousand km (excluding some problem models engines that are quite prominent out there) and so when they are due we want them to last at least the same if not more time/distance.
