How do we do it ?
With the latest technology in injector servicing & refurbishment, we are able to test up to 8 injectors at a time to compare spray patterns from one injector to another.
This will determine which injectors are causing the problem.
We are also able to test the pulse, leakage, cold start, and flow rate delivery of each individual injector.

The injector has the finest tolerances of any mechanical part on the engine.
Regular servicing of injectors (every 40 000 – 60 000 km) will not only maintain Performance, Fuel Economy and minimum Exhaust pollution, it will also prolong the life of very important components like the Lambda Sensor and the Catalytic Converter.
Both of these items are very costly to replace when they have failed, protect them now and save money.
At what mileage did you have your injectors serviced?
Once we have tested the injectors, they are ultrasonically cleaned in a special bath.
Ultrasonic cleaning of injectors is the only way to guarantee the injectors are clinically clean and back to their original condition.
After the cleaning process, the injectors are once again tested to ensure that they are functioning correctly.

  • Recognize any of these problems?
  • Starting – Will not start properly
  • Idling – Uneven idling
  • Performance – Loss of power, flat spots
  • Economy – Poor fuel consumption
  • Drivability – Hesitates, engine “pinks”
  • Lambda Failure – Slow in response
  • Catalyst Failure – Failing but no cause found

It becomes necessary from time to time to check the injectors for:
-Operating Pressure -Sealing Ability -Spray Pattern -Shutter Effect
Most important of all, it is necessary to first establish whether or not the correct injector nozzle is being used.
In our experience we have found many a diesel to be running with completely the wrong injector nozzles, which is normally only identified when the vehicle is not able to be tuned to perfection.
In most cases we are able to save an injector nozzle if it has not been abused and exposed to very high temperatures for long periods of time.
The injector housing is stripped and the nozzle is removed.
We make use of an ultrasonic bath in which the nozzles are cleaned and then inspected.
If there are no signs of melting or pitting on the tip, we are then able to assemble the injector and shim the spring to operate at a specific pressure.
The shape of the operating pin in the nozzle is also very important, as this enables the shutter effect, which atomises the diesel as it is injected into the combustion chamber.
If we were not able to save the old tip, the entire process is the same, except for the cleaning of the old nozzle in the ultrasonic bath.
If a new tip is used, it still needs to be tested and shimmed to perfection.
In our opinion, if injectors are serviced regularly they will last as long as they need to, in most cases they will outlast the engine.
