Hi all,
I have a 2004 Patrol 3.0 ltr with 110,000km, when should I look at injector servicng and who can you recommend in
Sydney. Am currently getting 9.5 to 10 km per litre around town.
Look forward to your response
Rob

Hi Rob
I have a 2005 GUIV with 112K. During my motor rebuild I took the injectors to a Bosch Service Agency. They said they could only do a limited
test, pressure and spray pattern. All was OK.
That fuel consumption around town is excellent. I get that on the highway.
What makes you think you need the injectors tested?
More importantly I would do the following:
fit EGT and Boost gauges, (so you can monitor heat buildup in engine when under load).
clean the MAF (on side of air cleaner hose) with CRC MAF Cleaner. You need a special Torq wrench #20 IIRC.
Remove the Inter Cooler and degrease the inside with degreaser. Thoroughly dry before fitting again. You'll be amazed how much oil gets trapped inside.
Only use genuine Nissan air filter.

Just out of curiosity
Malcolm does this engine have Piezo injectors....if so I'm guessing that "servicing" is at much larger intervals than 100K or even 200K if at all. Given that this type of injector is a composite piezo wafer do they need servicing at all?

Patrol22,
you are most probably correct - 'do they need servicing at all?".
Nowhere in my workshop manual (gregorys) does it mention anything about these injectors needing service.

Hi
Malcolm,
Thanks for your informative reply, I was only assuming the injectors needed servicing at some stage as with previous older diesels I have owned there was always the need to service at usually 100,000 km. I will investigate under the bonnet with your suggestions for the maintenance tips you offer.
Easter Friday We (family) are off to
Taree for 3 nights stay at my dads, then camping 4 nights at
Emerald Beach Caravan Park, cannot wait to hit the road, have a great
easter,
Cheers Rob
