I have been towing my small Van, for about 8 years now with my 2004 tw Magna, has served me well, not one problem. I have been always been wanting a diesel 4x4, I took the plunge , and parted with some hard earned cash, 'ouch' and got a real nice one, I love it. So I start to look at what it takes to look after it................Oh my God injectors, $500 plus each , How long do they last, ? i suppose , that is in the field of good luck. OH no then their is the injector pump, $2000 plus, and this could go any time if luck runs out too. Well have I done the right thing? What sort of klms should expect before things go wrong.

If its is Japanese you should be ok for a few years ( maybe some landrovers included to be fair )
If not ,well good luck
Make sure you service it ( oil 5000km intervals ) and touch wood it will go forever.

Happy 4x4ing

Cheers

Just make sure you don't put petrol in it and you will be OK.

The enemy of Common rail is also water so be very picky on where you buy diesel which you already should know if you have done 3KK. I have a Mr Funnel which I have only used a couple of times , but then my Land Rover has a water alarm in the filter the same as a water watch, and a D2 is not common rail.

The common rail computer will automatically adapt to injector wear so it should go for a long time with proper maintenance.

I really like my D2 TD5 and I was always a petrol head.

At 47 K it's not even run in yet. Log book servicing and an additional fuel filter with a water alert and you should have many years of trouble free motoring. Maybe add to that a low coolant alarm.

Those magnas were a good vehicles with heaps of grunt, but I think you are worrying to much.

You have chosen a good vehicle and as long as the fuel is clean it will last a long time.

I often see posts about common rail light diesels needing injectors and pumps at very low K's (100,000 to 150,000 K) but this not the case in my world. If the fuel is clean, they can go for a very long time and I am talking in the 400,000 to 500,000 mark. Many Tojo people talk about 100,000 K injector replacement but that is not born out in practice unless you have fuel problems.

Couple of hints. Don't drive short distances and keep the fuel tank full.

Now use that 4x4 for what it is designed for and enjoy the country.

I have had several diesels now that have done in excess of 250,000km and I have yet to require an injector replacement or pump overhaul, and whilst there can be a certain amount of luck involved the main issue is for a plentiful supply of clean fuel. Essentially double filter your fuel (additional fuel filter preferably with an additional water trap), and change them often.

If you are concerned about the costs involved when dirty fuel gets into the system you will find that the better insurance companies will come to the party especially if you can identify the source of the dirty fuel. They consider it as damage caused by a single unintended event, which is the same definition as a crash event.

I purchase all my fuel by EFTPOS and I also always get a receipt and keep it on file, as far as practical I use the same outlet or fuel company.

Turbo's also require a plentiful supply of cool clean oil, hence do not let your oil & filter changes go too long. It is a good idea to do all your servicing based on fuel used. If the manufacturer recommends 10,000km servicing then that is the period that they consider servicing should be done under ideal conditions (i.e. light load with mostly runs of a reasonable distance probably about 50km or more), consider the quantity of fuel that would be used under those conditions and then base your service intervals on that quantity of fuel use. This formula is used for most heavy machinery including earthmoving and power generator equipment, and also heavy transport fleet operators. In my case with a Landcruiser 200TTD I base all my servicing on 1300 litres of fuel used, which could be anywhere between 6500 and 10,000km.

Hope this helps.

Also use a good quality DIESEL engine oil, one where the C rating is shown first (i.e. CF4 or better)

hi
Fuel filter every 10,000km
If using drum type fuel/ bush fuel a separate water trap maybe needed
On a direct injection diesel any sensor in the inlet manifold have cleaned every 10,000km .cheap and simple
Have a camera put down the inlet manifold to check for a build up of sludge [combination of EGRgas and PCV gas ] every 50,000. If let go ,this can severely effect performance..
There are different ways of removing build up
On car if build up is light [ on car flush] or if heavy remove manifolds to clean
Depending upon type of egr but cleaning this is always a good thing

Not much I can add as most of the issues with the care and feeding of your diesel have been covered in the above posts. Just a comment.

And just my opinion. The injector change interval which may at first seem a little extreme is based more on the engine's ability to meet strict emission requirements than the fact that one day you may find it just will not start.

My 2010 colarado has just cliked over 200,000 klm and has had no more than regiular log book servicing and has been terrific so far. 47000 km is not run in yet :) my fuel economy improved out of sight once the car turned over 100,000 km

The quoted price for an injector is probably for the whole injector assembly. Some (most) can be serviced and have the needles and nozzles replaced, sometimes though they are just stuffed.

For a service such as injectors I'd take it to a specialist as a dealer is keen on getting you out the door as quickly as possible for the maximum profit, so they would just change out an assembly rather than overhaul the ones that are there. Overhauling the injector takes a bit of time and requires specialised equipment, all of which the average dealer mechanic doesn't have, they also don't want your dead car taking up workshop space while your parts get sent off to a specialist.

I was quoted $750 for cylinders 2 to 4 and $1100 for No. 1 on my old wagon. Due to a failed piezoelectric lift sensor in the no 1 injector I had to replace that after 110000km, the other 3 were $250 for an overhaul. 5 years later at 220000km I got all 4 serviced for around $300 (I did the remove and install).

Injector pump was still going fine after 270000km. I ran twin filters, but I also ran biodiesel and waste veggie oil as well as servo diesel. I wouldn't be keen of running it in my new BT50, but as long as the fuel is clean and has no water then the components will last a long time.

BTW, I only had the injectors serviced as I was down on power, but it turned out to be the air flow meter and completely unrelated to the injectors. Injectors were within spec (except for No. 1 which was having issues), but while they were out...

"What sort of klms should expect before things go wrong."
======================================

Good question but there would be a 99% chance of the answer being a long time.

The book for my Hilux lists servicing schedules up to 250,000 ks but does not mention injector servicing in any of them. I bought the car at 42,000, it has just reached 150,000 and is running better than ever. I have kept a record of all the fuel that I have put into it and the consumption today is consistently a little better than the early days. There is no reason at the moment to touch the injectors.

Injector problems will show up in fuel consumption and performance so just keep a record of everything and keep driving.
