Diesel Injectors

Tks wicket, will contact them

These guys would definitely be my first phone call.
Have not needed them personally but know of a number of others that are very happy with their product and very good pricing

Hi Dennis
to be honest I'm not sure, I have just (8 weeks ago) purchased it as a replacement for my Triton.
I love it, I'm getting 13lt/100k consistently from when I first got it and the power is amazing. (bit like being 18 again). But when cold it blows smoke and rattles. Getting better now the warmer weather's here

I have no complaints as I got it well below market price. Even if I have to spend $ on it.

Have a look on the Bailey's link Dennis. Quite interesting to read about what can happen to the injectors to cause the rattle. The computor coding is interesting as well. Bob.

Blowing dark diesel smoke when cold, sounds more like glow plugs than injectors..

"Blowing dark diesel smoke when cold, sounds more like glow plugs than injectors.."
Can you please tell us how that works

When it is too cold to fire in some cylinders IE, glow plug not working, the injected diesel doesn't get burnt but the engine does start and when it does, the rate of compression is increased and so is the heat of compression which then fires the newly injected fuel along with the previous and it has to get rid of it all, and so lots of fuel is burnt, or tries to be burnt in a short time but it is too much for the available air and so it comes out a black smoke.

Thanks Rowdy, good to hear your happy with the service will contact him

Tks pop, just been down to see one of them, very professional, leading so far just want to make sure their price is competitive, they do their quotes on landscape A4 so they can fit enough zero's in :-)

Not sure what you are getting at or the point of such a comment but it is a common rail problem that all manufacturers suffer from

Mmm, first Toyo I've owned, love it. Is it a common problem? seems like the answer is yes going by what the diesel (very well known) mob have said. Knowing what I know now would I have bought it 8 weeks ago, ABSOLUTELY

Thanks Ross, sadly had diagnostics run yesterday and seems all but 3 injectors are out of spec, funny he only seemed concerned about 2 which were way out. talking to others (i.e. mining industry) seems like it common. I think I would like to get it fixed then I should be right for the next 5 years.

Noldi
If they are out of spec, then why are you getting better economy than almost everyone else who owns the same model cruiser???

Perhaps they all run out of spec and no one ever check a new set.
I would like to know more and also talk to someone who will be willing to trial settings, ie control code numbers alteration so the ECU can control them more closely, and not just someone who says, You need a new set.
It is all too easy to throw away working injectors.

if you get new one fitted, make sure they test them the same as for used injectors so you know where you are starting from as some of them may go OUT of spec shortly after being fitted.

Thanks Wayne, will give them a ring. 165k ex mine vehicle (company I work for) Yes glo plugs (at least has the light on the dash) Valve clearance don't know, not sure when glo plugs were replaced if ever.
Diesel mob said generally 150 to 250k for the injectors. Discussed with the Treasury last night and she agreed that its well worth getting fixed

I ditto Wayne's comments completely. The injectors need to be diagnosed by a professional.

"A recent conversation with my mechanic indicates that,
Injectors are to be replaced every 100.000km
and valve clearances need to be checked and reset every 40.000kms."

You need a new mechanic. The valve clearances are self adjusting on the 1VD-FTV V8.

Phil G I recall apost from Baileys that I am pretty sure they said 140K is the expected lifespan.
I have mates with CRD D4D motors with over double that on original injectors and then others that have not made it to 100K.
So probably the way to go is to have them checked at regular periods and only change them when they are stuffed . They are too expensive to change if it is not warranted.

Gday Alby,
I was just correcting the posts above regarding valve clearances and avoiding the embarrassment of Ian walking in and asking the dealer to adjust his non-adjustable valve clearances!!

Tks Olcool, had the diag done yesterday 5 out of the 8 were OOR, he also said I have the choice of doing nothing (did not indicate it was critical in any way or shape) I contacted Baileys, it is apparently a 1VD-FTV engine and it works out about 4k for the injectors, then I need to get them installed.

Fitting them is no big deal but you need to recode the ECU for compensation for each injector.

You don't know how far out they were?

Can't remember the numbers really

Hi Terra, I have the VIN no. I sent it to Baileys they came back with a price but did not mention the model number of the injector.

I organised a mates Navara recently , 4 new injectors , the diesel mechanic (Well Known in Bayswater, Victoria) quoted $3300 supply and re-fit or $500 to just do the re-fit. You will need your exact injector model and brand such as Denso 90250_____ etc

Gday Frank,
The common rail 1KD-FTV motor appeared in 2000 in overseas delivered 90series Prados. It was just pretty slow to come to Australia because of too much sulphur in our diesel, so we were stuck with the 1Kz-te. It first appeared in the Aussie delivered Hilux in 2005.
Cheers
Phil

I didn't know that Phil.

In the early iterations of the D4D Prado in Aust, apparently 7 years after the engine first appearing OS, there were a significant number of injector failures, some within the warranty period, some not.

If you were lucky you had a good dealer or mechanic and the problem would be picked up before any engine damage occurred. If you were luckier it would be within warranty. If you were luckier again your dealer knew enough to accept a warranty claim and document it so that Toyota would pay.

If you weren't so lucky (out of warranty or dealer dodging or ignorant of the issue) then you were out of pocket by about $2500 to $7000, depending if the repair was done outside or within the Toyota network.

I was one of the lucky ones, I had a switched on dealer who identified the problem before I did and fixed it under warranty during a scheduled service. Many were not so fortunate.

There is a second issue with these injectors. The original seals between injector and head were copper washers. Again, there were and continue to be a significant number of seal failures. These usually occur outside the warranty period. The failure permits blow-by of combustion gases into the rocker area, causing carbonised oil granules to form. These wash down to the sump and are screened out by the sump oil pick-up, which eventually gets blocked enough to starve the engine of oil. Usually #3 piston seizes first. Happy days.

There were recalls or dealer service directives in Europe and NZ over both these issues, but not here in Oz. You have to wonder why.

Cheers

Frank

I should have said in the above Follow-up that Toyota have redesigned both the injectors and, later, the sealing washers, which kind of acknowledges the original deficiencies.

It's possible these issues could carry through to the V8 (same technology and market), so IMO Noldi should follow them up.

Cheers
