Replaced My Injectors as a Precaution. So Worth it!

[ttmx83 Member Find all posts View Profile Close ttmx83]

So my 2010 GX had 113,900klm on it when it started to get the smallest rattle, cold and hot. So I parked it up in the shed till I could get it booked in to get the injectors replaced. I wasn't prepared to let it go any further and you can see, it doesn't have very high kilometers on it. I'm glad I did!!!:

The car is so much smoother now, I mean it was before, but now it is smooth and quiet. It's probably got a slight amount more power back but the best part is, almost 0.5L/100klm better economy.

I have an extra 30 micron pre-filter on it, have for over 40,000klm and I get my fuel from the same place 95% of the time. I use an additive/cleaner every tank full at the recommended dose and have done since I bought the car. The reality is, injectors are a consumable these days, as shown by the fact that the injectors were out of spec at these kilometers. I care for my Prado as best I can and nothing you do can stop these things wearing out.

I had the injectors replaced with Denso genuine, new pipes, sheets, seals and had the EGR cleaned out. All coded in and re-learnt and it's running beautiful.

My advice is to be prepared to change them out as the car approaches the 100,000klm mark and eliminate the chance of having to buy a new engine, as some before us have. Keep your ear on the sound of the engine, especially if you don't get the feedbacks done on a regular basis.

I can pass on the details of the tech that completed my job. He has a very clean workshop, has experience doing the injector job and went the extra mile to make sure all aspects of the job were done properly.

Cheers Brad

I agree - it is well worth the money to have them done. I recently did mine at 140,000km (2008 120 series), and I couldn't believe the improvements in how the engine ran - smoother and more powerful. I only had knock on cold mornings, and only for a short time, but definately don't regret doing the job early.

What sort of $$ are we talking ?

As I posted in another thread, even when changed you can have a complete engine failure. Changed ours after the rattle started at 150000 with denso and piston failure 50000 later.
Recon engine in, new baileys injectors, should be right for another 100000.

Just an approximate figure will do please...what sort of $ did it end up costing you all up to replace the injectors and anciliaries ...?

I think brad is on shift atm.

New DENSO injectors is what was used, new pipes etc. parts is. Bit over $2000.00
With labour & egr clean its worth around the $3000.00 total.

Once again, I think prevention is better than cure.
Check your feedback values every 10,000klms.
If in doubt, rip them out!
Once over 100k, it's pretty well getting close to time to change them.
Even if your feedbacks are ok, you are due for an egr clean & the injector tips may likely be carboned up which can cause problems.
At 120k you are due & your vehicle requires a valve clearance check, so while most of it is apart do yourself a favour a throw a fresh set of injectors in.

Cheers,

Hello Brad,

Just out of interest, with the Denso injectors and other parts, incl labour, what was the approximate $ cost of your injector job?

Keep this in mind peeps, this is why you need to monitor them. The 10,000klm check

Also don't let them get too bad before they are removed, that is the too late part, get them out before its too late

Hey Russel, do you have feedback values of second set of injectors when it went pop?
Also how bad were the first ones, when they were changed?

[Rusty62 Advanced Member Find all posts View Profile Close Rusty62]

Sorry no values as we didn't have Techstream. We do now and will check every month. Any change in values will result in a change.
First ones looked ok no gunk on the oil pickup. Second set ( denso) had more carbon build up. Cleaned inlet manifold and egr both times.

Next car will be a 100 series with Gturbo upgrade as we need the 3500 kg tow rating. Would not have another common rail diesel if keeping for the long term. Any thing over 150000 is long term for common rails.

You do a lot of heavy towing by the looks of it, is that correct?

I paid around $2400 for a set of Baileys Diesel Group (BDG) injectors to be fitted with new fuel lines and full throttle body and inlet manifold clean.

Our camper is under 1000 kg so not heavy. Tow approx 7000 km a year and the rest is easy stuff.

Hi guys, interesting reading. I am looking to buy a 2010 GX with 75k on the clock. Does anyone know of a good place on the south side of brissy or west (indro) where I could get the injector values checked before dropping $35k on a potential lemon?
Thanks in advance, Rich
