Can you PM me your name so that I can look for you when I have my rover checked and serviced. Thanks
Why do you need to have your injectors serviced? My suggestion: "If it ain't broke, don't touch it". This is unnecessary expense.

Fyi, it's the injector which is calibrated, not the nozzle tip. The nozzle is a part of the injector assembly.

Here's how work is done on the injector:

  1. Upon arrival of vehicle, engine will have to be cooled down for approx. 30 minutes.
  2. Time to dismount injectors depends on the engine configuration. sometimes, intercooler and/or other components may have to be removed to gain access to the injectors. This may take from 30 mins to 2 hours.
  3. Injectors will be tested/evaluated for proper opening pressures, spray pattern, and automization, about 30 mins.
  4. Good or bad, injectors will be disassembled for cleaning, and checked if installed parts are correct. We have seen injectors with the wrong nozzles installed. Depending on the situation, nozzle/s may be reused, or will have to be replaced. Injectors will then be reassembled and calibrated... another 30 mins to an hour.
  5. Injectors and other previously dismounted engine components will be reinstalled. Engine will be started, and air bleeding shall also be done.

As you can see, the whole process can take from a half day to a whole day. It is also possible that when you come in, all service personnel may have already been deployed. If this is the case, you will have to wait for our next available technician.

I will PM you.
