Default Injector lifespan 3.2DID

Wondering if anyone has advice / experience in the expected lifespan of diesel injectors.
I have the NS 3.2 DID and been advised by a service mob (dont want to give out names) , that about 150k is usually about it. Mine has now done 159k has poor fuel economy but otherwise fine ( now that ive had the scv replaced).
The engine is making a bit of noise which they claim is a sign they are on the way out. $3500 fitted to replace.
Your views would be welcomed☺

Have you tried using injector/engine solvent/cleaner? A new set of injectors is pricey so maybe try the decarboniser/injector cleaner first. If you do have to buy a set I,d try AMAYAMA FIRST AND SEE HOW THEIR PRICE IS. gOOD LUCK.

The local diesel specialist in Lismore, who rebuilds the NP injector pumps, told me the injectors shouldn’t need looking at until 500,000km. He checked mine when I had the pump rebuilt around 300,000km. and said they were fine. He drives a Pajero himself.

I think you should get a second opinion before forking out $3,500 for possibly no reason.

Cheers

Geoff

Unsure what the previous owner did to mine, but I am 230000kms in an 07 NS with zero issues. i did tidy mine up when I had them out, jsut removed carbon. otherwise nothing internal. all seems fine.

I ran a can of Luqi Moly Diesel Purge through my NP 3.2 (~175,000km and injectors never been touched). Afterwards there were a few subtle changes - it idled a bit quieter/smoother, cold start was quieter and so far after a few tanks of fuel I am getting another 20-30km per tank.

Might be worth a shot, less than $20 a can!

See attached info re Suction Control Valve. Watch video and see if this rings any bells. About 150k is when they start to go

Just had my injectors replaced on the NP, a touch under 300000k... Engine is a bit quieter, and used quite a bit less fuel, although that didn't seem to have lasted long. Apparently the old injectors didn't test out very well when checked. Goes in next week for head gasket and head reco, hopefully the last of the issues for now!

My NS injectors were replaced for new ones by local MM dealer at 170,000km. $4.5k. Said to be leaking badly. Thankfully I didn't pay a cent for that little project.

People in this thread are posting about NP and NS injectors.

NP used a an electronically controlled rotary injection pump. The NS is the first of the common rail engines, which use an electronically controlled injector. They're so different that there is no meaningful comparison.
