Hiya, I've got a low km 2015 Hilux 4x4 with the 1KD. Is there any real world advantage in doing the EGR delete module on this motor? I've been reading a few Aussie forum pages about it but no real conclusion of real good or a waste of money.
My understanding is the valve is only really working when at a constant cruise under low load, not at idle or acceleration.
Anybody done mod's to this model and have experience to share?
Cheers....
Yes worth it
i havent built a kit for the hilux yet but its pretty much convincing the engine management that its cold outside. the ones i built for the 4d56 mitsi work well
Apparently the Toyota cannot be tricked into keeping it closed with the resister in the line to MAF sensor like most other vehicles.
I got a delete cable for the Triton before I even picked it up so no soot in my intake.....helps a bit with throttle lag too.
This for the hilux.

Modern diesels are good engines its just all the carbon they breathe that roots em.
Ok Guys What about DPF on Hilux?
Yeah Cam, I spotted that unit for sale and one other thats an Aussie system nearly the same at AUD $160. Apparently these do work on the late 1KD with the variable EGR. https://www.aironboard.com.au/store/...2005-2015.htmlQuote:

I had a diesel that wouldn't rev over 3000rpm, inlet manifold was so full of crap that airflow was reduced about 50%.
Goes much better now its cleaned up and EGR valve blanked off.
Can't help with making it possible on your vehicle though sorry.
"royal egr cleaner" from partsmaster is good for cleaning providing its not totally gunked up.
only thing i found that actually worked, just make sure you do it outside because its smoky and stinks
Don’t bugger around with the EGR, fit an oil catch can to the crankcase gases line instead.
Much better to remove the source of the soot (oil vapour in crankcase gases) because even if you are blanking the EGR, the oil vapour is still going to go into your intake system. Instead of soot from the superheated EGR gas cooking the oil vapour, you end up with sticky gummy crap instead.
I’ve run a Hilux 1KD with a Provent filter since new in April ‘14. When I inspected the intake system at timing belt time, it was spot on.
I used to spend a lot of time on the Australian Hilux forum when I built my vehicle, and there were several tales of problematic fault codes after blanking the EGR. In the end if guys insisted on taking the heat out of the equation then the only reliable way they could do it was to fit the blanking plate with the hole in the middle, so the ECU didn’t see a fault. But you still get some heat and therefore some soot. So just take the oil out of the equation. Or if you absolutely insist, then do both, but definitely filter first.
I have to beg to differ there.
Engines have been breathing crankcase vapor for the last 30-40 years with no problems.
The source of the soot is the soot (go figure) that comes out of the exhaust and is routed back into the intake via the egr valve.

Nope.
It’s the introduction of the EGR heat to modern diesels that is the problem. These were introduced to control NOx emissions. Older diesels didn’t have them, hence no heat and hence no soot.
Yes there’s some soot in the EGR gas, but the combination with the crankcase gases and oil is what causes the modern phenomenon of totally blocked intake systems.
I should do a video of what comes out of my drain line from the oil catch can...
The vehicle i referenced above was an old school mechanical injected diesel, EGR valves clogging up happens on older diesels too.Quote:

I mentioned doing a vid, so here it is. I talk too much.

Hot egr is no good for emissions so it needs to be cooler which cools the oil vapor which mixes with soot to form sludge
Smaller engine making more power needs more boost so more oil vapor
Shit idea for a shit problem
Shut it down and fit a catch can and you will be sweet
Been running wurth egr cleaner for awhile for every service , helps but not if it’s too far gone
Also previous video, you should see what comes out of a euro 6 on catch can will make ya cry
Then you ad a dpf, just another sweet idea
:cave::cave::cave::cave::cave::cave:
I've just finished cleaning a manifold from a late model ZD30 patrol with a EGR cooler. 110,000ks on the clock and yep she had atleast 2mm layer of tar on all the intake ports. scrubbed with petrol and left to dry. EGR has been turned off via remap and I took the time to install a blanking plate.
This goes to show the EGR cooler was ineffective at stopping tar build up.
If you want to step into a later model lux with DPF
Misunderstanding or not knowing how it works is the problem with DPF fitted vehicles, they block up from repeated short runs and not being able to burn off. (some ECUS control burn off until engine is a temp & moving) I know Isuzu Dmaxs gets around with DPF back pressure gauge for owners to monitor which can be quite handy knowing when you have to take the vehicle for a decent run when gauge is full.
Owning a scantool & learning how to force a burn off should be considered.
Ask John Wills he will set you on the correct path ,may even score it for you .
Funny bugger ;)Quote:

Think its same or similar engine as a hilux. I tried to tell him about the provent but it went in one ear , out the other. He said “ the toyota mechanics hadnt seen that issue before “ ,oh really!
