I've just bought a 2000 TD jackaroo and read with interest the troubles others have had with starting, injector seals and oil selection. I don't have any of the starting problems others have mentioned but am interested to know what my oil pressure gauge should be showing when at idle and at hwy speed.

Scott. I have a 7/99 td jack and am very pleased with it motor wise.
The injector seal problems are fixed by 12/99.
the correct grade of oil is very important for cold starting as the injectors use engine oil pressure to operate.
There is a recomended oil list issued by holden that I have a copy of I can email it if you wish.

Scott,
A friend of
mine has had 2 Jakaroo Turbo Diesels, and had trouble with both of them - specifically the injector seals. Basically, once they get a little "old", they become less flexible, and can "leak". In his case, this led to a major problem whereby the engine would rev out, even after the ignition was turned off. This was due to the fuel getting past the seals and allowing combustion to continue, even when the throttle(electronic) was released. The high-pressure common rail system puts a lot of stress on the injector seals. Apparently, Holden now recommend that the injector seals be replaced every 20,000 km, plus the use of synthetic oils. Ask your dealer about this. It may
well be relevant to any other problems you're having.
Regards,
Stuart

I used to do a lot of work on these diesel Jacks and Rodeos at a country dealers, the seals can be easily damaged along with the loom when doing the valve clearance adjustment as the injector loom and assembly is removed for the service. The early seals were definetly a problem.
The starting problems caused Holden a lot of headaches for the newer Jacks and Rodeos, to the point where Holden actually fitted dual battery set ups to the Jackeroos to allow them to crank over for extended periods of time, the fix is simple, you have to run a low viscosity synthetic oil like
Mobil 1 or bleeps Supersyn 5w-50, for use up in the high country bleeps GT1 0w-20 synthetic is ideal for the winter. This is because even though the injector rail is electronically controlled, the injection system relies on oil pressure to fire the injectors, and a normal junk 'dealership' oil is too viscous to flow through the fine orifice.
Also be aware that the Jackeroo td has two seperate but interlinked oil systems, one for
the block and heads and another for the injector circuit.
It takes approx. 3 oil changes to completely flush the system, there is also a seperate oil filter for the injector system which you should ensure is replaced along with the normal crankcase filter.
Also watch out for radio interference caused by the injection computer because it runs on an AC frequency, Get it fixed under warranty because you get a new aerial for free!!
Hope this helps, good luck, Brad
