D4d blowing black smoke! mostly under acceleration

Postby 2006 Kun26r on Mon, 04 Jul 2016 6:43 +0000

Hello everyone! My 2006 d4d hilux dual cab is blowing black smoke mostly under acceleration ,I have been to 2 seperate diesel techs and both have put the scan tool on and checked the injector values no1 0.63mm3 no2 0.16mm3 no3 -0.63mm3 n04 -0.31mm3,the guys also said that they are within spec and that was what both diesel techs said from 2 different shops! before i took the lux to the above techs i pulled off the whole intake and coolant chamber and the amount of carbon built up was unbelievable,cleaned out and reassembled with new gaskets etc and it ran great with more power and no black smoke,after a week or more the black smoke came back and is what it was like in the first place, what else could it be PLS HELP!

Check for boost leaks with soapy water, missing hose clamps or loose flanges where the intake gaskets are between the elbow and egr valve etc

Hi ,

I know this thread is two years old.

However im having the same issue with my lux.

Black smoke when accelerating, Otherwise clean at idle.

There is a Unichip and K&N Filter installed. I disabled both the chip and reinstalled existing paper filter.I have also tried adding fuel additives for fuel system clean and injector clean.STILL SMOKE! :evil:

I spoke with diesel experts who keep persisting its the chip, My local mechanic blamed it on poor quality fuel and
my air filter.

What should i do from here? I was thinking to get the egr system cleaned and injectors inspected , am i heading in the right direction. :?:

Thanks

Dennis

How much smoke are we talking about here? Injector values dont give you a complete story.

Get yourself a mini vci techstream from ebay or a print out of all the parameter values from your mech and post them here.

In the meantime - dont get too stressed. Your injectors are likely to be worn at that age but before you change them out do a search here for things like cleaning your scv, cleaning the MAF, replacing the boost sensor filter and importantly checking you oil pickup.
I might be wrong.

It isnt huge clouds of smoke. More like puffs.
Sort of greyish white... Not completely black.

Spoke with a diesel expert from cornwells diesel in sunshine west and was able to book in a diagnostic service.

I wish i could do all the basic stuff like egr clean and replacing filters, But i just havent got the time nor energy after work.

Just ordered a mini ob2 techstream as suggested and will post the results early next week.

Thanks for the replies.

I hear there is a specialist d4d mechanic over in Hillside. He is worth talking to.

Mate - if your mechanic isn't the bloke suggested above, I suggest you take the report to him.
