Jackaroo 3lt TD 2000

Juluka,

Was this a dealer or another workshop that performed the service?

20-50 oil is way too heavy for that motor. It's what Holden specify for the petrol V6 and not the TD. I believe it's also too heavy for the V6 in cold weather, as it takes an uncomfortable handful of seconds to make its way to the top of the engine.

In the 3.0TD, the injectors are hydraulically driven using the engine oil. If the oil is too heavy it won't circulate adequately when cold to get the injectors operating. This is why you have a starting problem and may explain the performance problem.

The 50 in 20W50 represents the thickness of the oil at operating temperature. The higher this figure, the thicker the oil. If Isuzu/Holden specify a 40, then they are specifying a thinner and more free flowing oil. The 20W50 might be causing the motor to be ineffcient, hence the performance and temperature changes.

The owners manual specifies 15W40. For cold regions 5W40 is specified. Have a read of post 8765 for a range of choices in oil for the TD Jack.

Castrol Magnatec is a 15W40, will work fine and is easy to get your hands on. About $25 for 5L. Penrite also have a 10W40 that works very well in Jackaroos.

You should see a big improvement straight away once you get rid of the 20W50 engine oil.

BTW ... Make sure that the injector seals get replaced at the 80000km service. There is a known problem with the 3.0TD motor and failed injector seals destroying the engine. This can be easily avoided by getting the seals replaced at 80000km.

G'day Julka,

I have a 98 3.0TD Jack, and it is a great truck. The previous posts are correct it like expensive oil. I bought mine in July and did an oil and filter change pretty much as soon as I got it home. Unfortunatlry the sales rep for penzoil was in the shop and he "conned" me into trying a new brand of oil called conoco it was 10W-40 pretty thin but not thin enough. I live in Hobart, so it gets cold here, not freezing, winter temps in the single figures.

The truck has been blowclods of smoke on startup and running a bit rough, vibrations through the seats, gear stick. On Friday I changed the oil again this time I used Mobil Delvac 1 5W-40 synthetic. I made the choice based on conversations with Mobil lube line, castrol lube line and 3 Holden service managers (2 here and one in Melb who used to service my vehicle.

The Melb guy said, use Delvac 5W-30, this is no longer a std product and is about $320 for 20L, Mobil lube line said 5W-40 is the rght choice $200/20L, castrol said Formula R Synthetic 5W-30 $55/5L. Hobart mechs said, Castrol Softec (same as Formual R) and Delvac 1.

When I quizzed the melb mech about Castrol Magnetec he said, "No, don't use that s**t, use Delvac 1 5w-30, there is 5W-40 but the 5W-30 is better."

This is not a cheap solution, but the Jack no runs smoother, no seat vibration, starts easier and almost no smoke on startup. I plan to change the oil again in a couple of weeks to fully flush out the other crap. Next time I will do the filters as well.

If you didn't know there are 2 oil circuits that are interlinked and it takes three oil changes to fully exchange the oil.

do a serch here for Jackaroo and you will learn a lot.

as other have said use the correct oil, if the toyota dealer serviced and put 20w-50w oil in it then they just don't know how to read the sign on the dip stick or the sticker under the bonnet on these motors say API 0w-30w or 10w-30w.
It wilt take 3 oil changes to get most of the junk out they have put into it out. most of the oils people have listed hear are fine for the jackaroo diesel motor. the toyota dealer should have on hand an oil that is 10w-30w as most of the modern petrol motors run these lighter grade oils already

Most or the toyota dealerships are going through a steap learning curve at the moment as toyota has started to intorduce some 1980's techknowlagy (electronic direct injection diesel has been around sinsce the early 1980's )into it's engine bays. the reason their motors run on these thicker oils is due to the larger machining clearances and tolerances basically they need a thicker oil to fill the gaps!

running to thick an oil increases friction and wear due to the "drag" caused by the increased thickness. a lot of people are killing there modern motors long before they should by using too thick oils in them, which increases fuel consumption, engine waer and pollution

if they wont use the correct oils and service the motor as per Holdens specifications you would have a case before the trade practices and consumer affairs if any damage is done by toyota's servicing.

Happy motoring

Thankyou all, so far it seams I am in for some oil changes, but any idea what sort of things would be happening if the injection timing was out or the turbo going, because one lot of mechanics suggested this is the place they would start because the oil could not possibly cause this problem. Also nothing came up on the computer with anything being wrong. Lastly just something that popped into my mind whilst reading some of the other articles is that we have one key, how could I get a second one because of the engine immobiliser being linked to the key?

Thankyou you all.

Julka,
Change the oil and then hunt for gremlins, my gremlins went away with an oil change and 20W-40 is VERY thick for this motor.

On the key issue, you can buy a remote from USA on ebay, they have three buttons on theirs but it works fine. This only activates the door locks not the immobiliser.

The Immobiliser is activated by the key itself, you will need to buy a key get it cut and then programmed by holden $$$$.

I am thinking about using my webspace that my provider give me to post some Jackaroo tips, any thoughts?

Good luck,
Glenos

Juluka ... I think I found the answer!

Download this pdf file, have a read and take it to the Toyo dealer. http://www.penrite.com.au/techbulletins/14_15_JACKAROO_LISTING_&_LANDROVERTD5.pdf.

It includes the Holden tech bulletin which states that the wrong grade of oil may cause poor cold starting, poor idle quality, excessive smoke, poor performance. ALL the symptoms your car is exhibiting.

It then goes on to name specific oils that are suitable for the engine.

Hi Juluka ... So how goes the Jack? Is she fixed yet?
