Hi folks,
I've got some follow up to the archived discussion:

Both oil filters are now available from Ryco,
Z79a for passenger side, mine is a genuine Isuzu and is labelled as not needing replacement,
Z600 for the drivers side, bigger one.
Fuel filter Z321.

Unfortunately they do not make an air filter, I was thing of changing to a unifilter, it's cheaper than genuine. Any comments?

Also, a question on oils, I work on a farm and when I was in the farm equipment shop last week they had heaps of different oils in 20L drums, they are labelled Agricultural and I wondered if they are suitable for my Jack? Have a look at these links for more info.

while Ryco make very good filters the Standard Z79a when sat up beside the genuine Isuzu filter looks to be a lesser filter than the genuine. for a Deisel engine.the Z79a is a petrol car engine oil filter, deisel's require much better filtration due to the soot produced(yes the Direct injection does make much less soot than indirect injection) the advice has been to change the smaller filter every second oil change if doing 10,000klm between changes(using synthetic/semi synthetic oils)
as for the fuel filter, the ryco looks very close to the genuine in internal construction & cost wise the genuine was only a few extra $$$, would use either my last one fitted was a ryco.

As for the oil remember they don't like thick oil (high lower viscosity 20w-50w etc.) at start up they can have cold start problems as the oil pressure is used to fire the injection. if you are in a cold area or snow country they recommend 5w-40w or 5w-30(snow country). most normal areas 10w-40w or 10w-50w. for 10,000 klm oil change intervals synthetics get the nod over most normal mineral oils.

when it comes to servicing anything, always remember it's cheaper to change the filters & oil than the motor.

The best way to kill any diesel motor is to give it dirty air, fuel and engine oil.

the Diesel mechanics that are floating around on here might have something to say about after market air filters and how some bit's of them end up inside the turbines in the turbo chargers (foam types)

good luck & happy travelling

Old Jack is pretty spot on ,I worked at holden when they were trying to tell us that the secondary oil filter should never be changed until an engine rebuild. I argued long and strong that the secondary filter is for the injection oil circuit and as the two circuits are interlinked , both filters should always be changed. Eventually they agreed, but it just showed that Holden have always demonstrated a total lack of knowledge about the Jackaroos and still continue to do so.
Unfortunately Glenos, the Jack needs top shelf oil to ensure reliability and easy starting, you should change both filters and use at least 5w 40 , but dont be scared to use a 0w 30 either, check out Mobil Orbleeps. for their fully synthetic gear.
Just bear in mind that it takes 3-4 oil changes to fully flush the old oil out of the engine injection circuit.
As for air filters, the oiled foam element filters are fantastic and superior to paper sieve elements, as it is the sticky oil that catches the dirt, not the foam. The only trouble with foam filters is that people don't wash and oil them correctly , or believe that they will last forever. Holden even fit finer filter elements under warranty to turbo rodeos because the paper elements fitted in the factory are useless and allow an excessive amount of dust into the engines.
The Jacks are expensive to service, but they will repay you with years of reliable work. Brad

good to here from someone who has been working on the jack's,
I have had conversations with a number of mechanics at the dealerships about the oil requirements for the motor, most of them where not using the recommended oil & can say that they are a dog to start if they put 15w-40w or higher oil into them(they did it to our jack at work) helps if they actually read the service info provided by Isuzu sometimes.

have been very happy so far with my jackaroo(3lt turbo), we have a petrol one here at work with 400,000 klm on the clock with original motor & gearbox, still looks good & the body has no rust in it. it dosnt blow any smoke & used about 3/4 ltr of oil between changes. had brakes done up,clutch and a few wheel bearings but otherwise is in very good condition. mind you it has been serviced every 10,000 klm

over time the servicing costs actually work out good value for money !

I've settled on Fina Filter for my TD jack - 18 months now - runs very well - not starved of air at all. I use Castrol Magnatec for the donk - change the oil at 5, with the main filter - change the small one each 10. The donk runs very well on Castrol Dynamax too - fully synthetic - bit dearer though, and only comes in 20's. For my climate, 10W-40 is the go (but she is touch and go on some cold mornings).
That's my formula. Gotta have red sand on those boots !

I use to use the finer filter, but found that with the snorkel I had to clean the filter every week in metro Melb! Have any of you had any dramas with both your intercooler and turbo. I have had probs with both, had put new ones on and am possibly going for my third turbo! So much for Isuzu reliability, I'll never buy one again!
