Do wreckers have any sets of injectors which would solve your problem? Perhaps some out of a cooked engine would be good for you! Even 1 injector might be all you need.
Are you sure it isn't an electrical connection problem and not the injector itself. It sounds like something which gets going after running for a while, generally injectors don't get better by themselves, may be wrong though.

RIP Jackaroo.

After over $3000 spent trying to find the problem, it turns out that the oil pump has failed, among other things. It takes forever for fuel rail pressure to get up to operating, hence the poor starting quality. Even with the engine up to operating temperature, air is drawn into the system and starves the injectors at anything above idle.

So now I have a 2001 Jackaroo rolling shell sitting at Port Augusta. Most likely will be scrapping if anyone is interested.
Parts of interest-
Snorkel
spotties
UHF
Rhino commercial roof racks
5 sunraysia rims, 4 brand new Bridgestone all terrains
Jerry can with rack, mounts perfectly to rear door
Cargo barrier
Dickie seats

That's sad news.
I have sold my Jack while she was still running fine.
I hope your next car serves you better.

Cheers,

Salty.

Hi Toobs

Sorry to hear about your Jackaroo. Have you got any pics of the Jerry can rack, and how much are you looking to get for it?

Thanks
Claypot

I spoke to the V6 engine conversion specialist and he has a kit to convert the 4XJ1 to VT/VY 3.8L ecotec for $3500.

Thoughts?

These engines have a HEUI (Hydraulic actuated Electronic Unit Injector) injection system.
http://www.dieselpowermag.com/tech/ford ... tems_work/

Came about when it was needed to create high injection pressures, electronically controlled, and independent of camshaft timing. The oil is used to multiply the diesel injection pressure. Later common-rail systems replaced them and became independent of the oil system again.

So yes it is possible for an injector "to come good" upon warm up. Quality oil of the correct grade and specification is essential for correct operation. And as has been found, any problem with the oil pump will also cause problems.


OK, one question. Do these engines have a separate high pressure oil pump in addition to the normal lube pump? If so, when doing an oil change on these engines, is there a step in the procedure where you also drain any reservoir to this pump?
Cheers, Dave.

OK, done a little research myself. Yes there is a high pressure pump. There is also a pressure regulating valve that can become contaminated and not work properly. Despite anything dealers might tell you, they can be dismantled, cleaned and re-used. This often fixes issues. If this is not working correctly it could give similar symptoms as air being sucked into the oil before the pump/s. Speaking of which, the oil pick-up has a habit of cracking in these motors. Apparently adding an extra 250ml of oil above the full mark is enough to submerge the crack and allow you to determine if it's present. Providing there are no other issues of course.

Incidentally, the IPR or ORPV is VERY similar to the one in Ford's 7.3 Powerstroke diesel. Interchangeable???? More readily available and cheaper......... [Ford part# F81A9C968AA, Motorcraft # CM5013]

So there's a few things to check before ditching the engine!
Cheers, Dave.

maybe fit a common rail diesel motor from a colorado/D-max. almost identical block so should just about bolt straight in and has similar power outputs.

Thanks for the reply DJ. Unfortunately the truck is sitting 300km from home so I can't tinker with it. Where did you find the information on the pressure regulating valve? Sounds like it might be worth investigating at this stage given that I've been going through the problem by deduction.

I haven't gone beyond dreaming of the possibility of fitting a different engine at this point in time. From my experience of working on petrol engines, swapping an engine from the same manufacturer/model does not imply an easy conversion. Getting the engine to sit on the mounts and mate up to the gearbox is one thing, however adapting the wiring loom and all the other auxiliaries is another story. Jackaroo V6 petrol engines seem to cost the earth and having an ecotec conversion won't do resale value any help either :(

Toobs, similar problems here at the moment too. The head on the old 4jg2 decided to crack on the last trip. Currently preparing to insert a 4jj1 from a 2010 colorado. Anything with a 4j__ engine code will fit.

Hey Toobs, the resale value of a non working truck which you have already thrown $3k at is is even worse. I you like it otherwise, then an engine swap to something cheaper/ more reliable is worth serious consideration. Can you hire a car trailer and get back home on the cheap? then you could think and play with it without stressing about being so far away, and easy to measure up ETC ETC. either way, god luck sorting it.

It could be an option and one I've been thinking about. At the end of the day the car isn't worth anything as is and spending up to $10 on a car that is selling for $6-8k on Carsales isn't an attractive option. Buying another trick to replace it will cost at least $15k and I'm still sick with a ruling shell I need to scrap.

Has anyone here rebuilt their diesel Jack with good results?

pull the old engine and drop something new in there.

A cheap petrol V6, or anything then sell it quickly at least you will make some of your money back.

Hi toobs
If you love your Jackaroo like I do spending $5 grand on a ecotech conversion might be the way to go.
I'm about to start tinkering with this option.in my donor Jackaroo which had the usual blown diesel in it.
My mechanic said if you are going to do it get the supercharged version. He could get a motor and auto gearbox for 3k, you then have to put a patrol transfer case on it.
Sorry I'm not further down the track with it, but that's the way I will be heading.

I spoke to the bloke that makes the ecotec conversion kits and he said the supercharged variantwouldn't fit.

Has anyone here paid to have their 4x rebuilt? I'm after a ballpark figure of anyone knows
