Evening all, I have been doing some comparisons between the Nissan 4.2TD and the the Toyota V8 as I am going to purchase one or the other second hand. Spoke to a diesel place today and we got onto the subject of injectors or cost thereof. Nissan $90 each. Toyota $900 each or $7,200 for the set. They are sealed and so they must be interfaced with the ECU and only Toyota service centres have the $5,000 computer to do it. The Toyota guy (I spoke to them after as I could not believe the price) said that the
mine site vehicles have their ECU's sent down when they need injectors and the ECU is put in a donor vehicle and then all matched up then taken out again and sent to the
mine site for install.
My mechanical knowledge is average at best so how often would you need to do the injectors? 100,000km?
Regards
Mark

My understanding is that the electronic common rail injectors are not serviceable at all, no nozzles or anything, replacement is the only way.
Don't know specifically about the Toyota V8 ones but most others can easily be damaged by crook fuel. Ask any Effie owner, they'll tell you about having to replace all 8 injectors after getting a tank of crook fuel. D4D Hilux's have had problems too, been brought up on here a few times, several grand for a new set.
Funnily enough toyota for one will not honour warranty even if the crap has got past the standard filter. Never mind that the filter wasn't good enough.

Call me a neanderthal but I could buy a complete new turnkey engine for less than the cost of the Toyota injectors and it would still be less when installed in the Humvee!
I've just got a new IP, injectors, gasket set, water pump, timing chain and a few other small items for less than $AU1k at my door here in
Sydney so paying nearly that for one injector is just crazy.

Sometimes I wonder if technology is going forward or backward with all these computers in vehicles. I do agree that pollution should be reduced. BUT now if they go wrong you need a computer to fix them. Diesels used to be simple. If they didn't go the only thing was that they were not getting fuel and easily fixed by in most cases bleeding the fuel system or cleaning or replacing the injectors. This does not include major break downs. Most could be fixed by the operator or your local mechanic who usually had three sizes of shifting spanner. I once had a Toyota 2H and because of replacement parts was fitted with a choke cable to stop the engine. Nowadays the manufacturers try to make the stopping and starting of diesel as similar to a petrol engine. They even call the switch an ignition switch. WHAT IGNITION.
Similar applies to petrol engines with all their computers. I do like the fuel injection system but the old carburettor systems were easily fixed if you got into trouble. There were no EGR valves or oxygen sensors and you usually made your own ignition leads. (Replacement lead for my 80ser. cost over $200.00)
I am 72 years of age so perhaps I am a bit old fashioned but when I open the bonnet of a vehicle and see all the stuff inside with no real room to move I cringed
