Hello all, first time post, and sadly asking for some advice/help.
I have a 99 TD Jackaroo, with ~135,000km on it now. I´ve had it for around 3 years, and not had a smoke problem before, but since late last year it has been noticeable. Driving lightly on the accelerator it seems clean, but under a heavy foot it blows too much, and too consistently for my liking. I did have the injector recall done last year, and some time after that it began (not to say that was the fault itself). Anyway, in case anyone reads this, here is the sad story:
* 12/10/06 4JX1 Injector Recall (126000km)
Check for injector recall
Found to be in range
Checked for and carried out fuel injector recall. Removed air tube, intercooler, rocker cover and removed the injects.
Cleaned head where injector seals sit. Replaced new injects.
Cleaned rocker cover and oil feed pipe and reassembled.
Road tested all ok.
... some time after ...
Vehicle blows black smoke with med-hard accelerating, more so with a heavy foot.
Fuel consumption went up to ~12L/100km (used to get between 10.5 and 11 L/100km)
Car feels sluggish, more noticeable in top gears.
* 25/01/2007 service at mechanic (130000km)
checked turbo boost - ok (13psi)
EGR valve working, replaced some vac hoses
checked intercooler for blockage and had codes checked on carmin code scanner - no fault
(10/40 Suchs oil put in too)
[he checked with diesel specialist, and apparently they couldnt think/
check anything else]
* 30/01/07 back to Holden, with their commentary:
Check for vehicle blowing smoke
Reprogrammed and checked over operation of injectors. All ok.
* 20/03/07 Car has
CHECK ENGINE light on and back to Holden
got the air mass meter replaced (I think)
[stopped the
check engine light, and car drove better, but still smoked when under med/heavy throttle]
* 28/03/07 Holden again
Check for vehicle blowing black smoke and poor fuel economy
Flash tested vehicle on road
test recommend changing injector rail oil sensor, rail control valve and rocker gasket.
* 03/07/2007 service (135000km)
lube & oil (magnatec 5W/40) & filter (z79a & z600 ??) change
¨found diesel smoke normal in our opinion¨
[I totally disagree with the last comment, hence the looong post]
The recommended work would cost significant $$, but they could not say with 100% confidence that it would fix the issue, but had fixed other Jackaroos with the same issue (could not confirm how many).
In (not so) short, I was hoping any other TD Jacks could share their experience and advice. If I need to spend so much money, I will, but Id like to at least hear some other suggestions.
Have read a lot on this site, so fyi Ive used majors for fuel, and I have
snorkel fitted.
Can anyone please offer some suggestions of how to fix my poor lil Jacky?
Thanks.
