Injector / Seals / Smoke / Blocked Oil Pickup

[07luxyTD]

Has anyone tried the injector cleaner branded by toyota thats specifically designed for our D4D engines to clean the carbon deposit?

G'day Buchanan,
From Experience, If you chase TMC hard on this issue, through Toyota Customer Experience, the Toyota service agent who identified this issue, with the Toyota Field techs working with the dealership, along with this Forum, and can show your D4D has essentially been serviced by the book, then you may find (as we did) TMC will ultimately support you on this problem if the failure is similarly related to the problem identified in the EU customer contact program on leaking seals & clogged oil screens. From experience this can result in most of your hard earned $14,000 staying in your wallet where it belongs on a new engine furnished by Toyota, demonstrating that the TMC network are ultimately prepared to help if you are really a persistent in chasing this help. In our case this type of help for a like issue was dispensed recently on a '07 Hilux with over 220,000 klm's on clock, so there is hope if this happens outside of standard warranty. Toyota have through this shown that for customers who properly pursue assistance they will get some, and all credit to TMC & the dealership for ultimately shinning through like this.

As a take on the biblical saying: "TMC helps those who help themselves!"

My 2006 D4D engine seized last week, it had been giving the occasional puff of smoke which I susspected was injector leak but didnt think it would lead to this.When I inspected the damage at the TOYOTA DEALER they explained to me the oil starvation had caused the seizure because of the blocked pickup which when I saw it I said whats with the crystals and why didnt my oil light come on.After reading all these posts its now pretty obvious and a pitty the guys at the dealership seemed to know nothing about it , the best they can do so far is offer me a reconditioned motor for $14,000 so its second hand for me!!!
Will try and post a photo of the pickup
Can anyone tell me if newer donks are compatabile say 2009 with my Aug 2006
I have heard engine management systems are different for pre Aug 2006
What was the Aug 2006 engine upgrade ? How can you tell the difference ?
TOYOTA are no help

Hey Grogfrog , good to hear you are getting yours sorted out by Toyota.

Hey Grogfrog , good to hear you are getting yours sorted out by Toyota.

Amen. What a relief after all that and there's hope for others suffering the same problem.

[jackolux]

It seems some ppl do a lot better with Toyota than others but they have to fight to get it , which sux.

I have just returned from a 14+K trip to the Kimberleys and I will say in all my travels over the years I have never heard so much " Camp Ground , Caravan Park " discussion about problems with 4x4 vehicle's

Mostly Common Rail Diesel problems , and everyone I think without exception was told " you must of got some dirty fuel " not just Toyota but they were top of the list for complaints and the blaming the owners maybe because there is more Toyotas out there

[Alby]

I think the biggest problem that is facing all manufacturers is they are being dictated to by the authorities to meet compliance on emission, safety etc targets to be able to sell there product.

The downside of that is they are focusing on developing products that comply which in turn are overly complicated and complex whereas in previous times it was about simplicity and reliability.

[jackolux]

That is right , if you believe what some Diesel Fuel Injection Services tell me ,

Its that diesel's have to comply with European Emission requirements ,so that means Turbo and Common Rail is the only way they can meet the regs , and Aussie diesel fuel is just not up to the quality of Europe

Its as simple as that , our fuel is crap ,
I have had Diesel Services tell me I can use as many extra filters and fuel additive as I like , it wont make any difference

Im not saying thats , 100% fact but I have been to that by more than one Service ,
Stuffed if I know .

Im interested as to how much it would cost to replace just the injector seals.......as having a few km's on mine it'd be something that would help me sleep easier

about $650 according to my local Toyota dealer.

Has anyone dropped the sump in a D4D hilux and have any pointers???

[StevenS]

Had mine serviced the other day, the mechanic took a look through the sump plug and gave the all clear (had it recorded on the invoice)

Unfortunately he found my clutch master cylinder is rooted and brakes need replacing all round

[obiee]

would you see the oil pickup with a inspection camera aldi have them for $39 might be able to view each time you do an oil change

Mate you don't need one, you can just look up through the sump plug hole

[noodle]

I did my oil change last weekend. All clear as well. 2007 hilux with 155k on the clock. Oil changed every 10k by Toyota (until this one). I had my injectors changed at 80k by Toyota as well

[Weekend Warrior]

hi guys new poster... looking to by a Hilux some time soon, got a quick question.

So from the research I have done there is two issues present here?

1. Faulty injector SEALS - leaking seals cause blow by gases to enter oil system, creating carbon particles which block the sump pickup screen, starving the engine of oil.

End result engine goes bang unless caught in time.

Fix is installation of new upgraded seals to injector only. (provided the rest of the injector system is working fine)

2. Faulty INJECTORS - faulty injectors can cause a whole range of issues such as high fuel usage, blowing smoke, poor power, rattles.

Fix is replacement of faulty injector(s)


Both these problems are related to D4D engines with 2005 - 2007 VIN numbers.

Is this correct??


Also if i'm going to inspect a Hilux, im going to request to drop the oil an have a look at the pickup screen before committing to buying the car. Is dropping the oil in the hilux as simple as removing the plug/bolt (where is this situated on the hilux? and is the plug gasket reusable?), having a look up there with a torch then filling it up with new oil.

Cheers!

Mate you have pretty well got it, sump plug seal is reusable. The injector problem is more of an issue and will be easily detected, the pick up screen has only been highlighted recently and appears to be an uncommon problem but is worth checking for peace of mind and monitoring as a maintenance check

Thanks mate good to know...hopefully I'll find a good one with a nice clean sceen and no injector rattles!

How much oil do the D4D's take??

cheers.

[07luxyTD]

6.9 litres mate

Alby You're on the money here. I've just changed mine and pick up screen was clean, I also checked inside the oil filler cap and you can see a machined surface on the top of the head and it was also clean. For piece of mind between services and when travelling, I'll check inside the oil filler because I'm sure some sign of trouble would show up there and if I see any sort of residue appear, I'll swear and curse a lot, then assume the seals are faulty and make whatever arrangements are necessary. Well before there is enough carbon floating around inside the engine to block the strainer, some of it would have to appear inside the rocker cover.
For piece of mind, get a milk crate to stand on and a tourch and go have a look, if the machined surface isn't clean or has any visible lumps or grains, then you have trouble.

Hi,

I wish i knew about this issue before i bought my hilux.

My 07 D4D hilux with 195000Km on the clock (purchased last month) does have the rattle.
since i've bought the car i've had it serviced by toyota, and another oil change the following week to flush any residue still in the system. my mechanic did suspect that the injectors are gone, so i took the car to Sydney City Toyota, and ordered to get them checked. Result is Toyota is saying the injectors are in range and they suspect no fault, and that the rattle is normal.

But what my mechanic tells me still has me worried.. and i trust him.

I checked my VIN number (MR0FZ22G3011*****) against the PDF posted on another thread (the Euro recall) and seems that my VIN is NOT in the range that is effected...

should i still be worried? what steps should i take to be sure? (i will be dumping my oil soon to take a peep inside the sump)

Thanks

They are two seperate issues, the blocked pickup screen relates to a faulty washer behind the injector and has no bearing on injector noise or rattle. Check your pickup screen next oil change for this.

If you don't believe Toyota about the rattle you could get a second opinion from a private diesel specialist?
