I have been informed by Holden service that there is a recall for the Holden Jackaroo 3.0 TD for injector problems. As many of you may be aware these vehicles have their quirks and problems away and above many other vehicles. The engine in them is actually a Caterpillar design but Isuzu decided to run the gauntlet and try to better it so to speak. This ruined it. You must run the correct engine oil in it as the injectors and fuel rails are inside the head under the rocker cover.The injectors are oil pressure fed from the pump on the lower left side. It looks like an injector feed fuel pump but it isn't. It is actually the oil pump for the injectors. Wrong oil grade and it runs like a bag of the proverbial. I had a customer ring me today that he had a "pop" then a "cough" and he had to full throttle it to get home in second gear at a top speed of 40 km/h. I told him an injector had gone west. He said "WTF". Holden has had a recall out on these vehicles for a while now. If your Jackaroo has not had the injector recall done go and get it done now. It won't cost you anything as far as they told me as they are under a nation wide recall. And if you know of anyone who has one tell them too. Secondly, I got caught with doing a clutch on one. This model has the crankshaft impluse sensor mounted on the right hand side of the engine bolted in to the back of the engine block on the lower right side next to the exhaust pipe. The flywheel can go in 3 ways as it is offset on the bolt holes. I have done over 2 dozen of these clutches and as Holden said "I must have jagged the position each time". Yeah, I can hear the whiners now.. mark everything. I didn't punch it I white marked it. Got it back from the machiners and the white mark was gone. Timed it up on the marks. I didn't punch it on this one and guess what? It wouldn't start as I was 120 degrees out on the flywheel. Put it on TDC lined it up with the crankangle sensor and she went Brrrmmm. My fault. 26 years as a mechanic and this one got me. My hands up.YEP MY FAULT. Anyway get the word around and hope this helps anyone out.

Regards,

Glenn Taylor.

If you don't mind me asking horseman, what went wrong with the fly wheel?

It's just the fuel injection system that uses the Cat design / technology.

Google "HEUI" and you'll read all about it.

The flywheel must be timed in with the crank pulley on TDC. It is very hard to see the mark for TDC on the[lastic front casing from the top as it is on the timing cover directly under the waterpump. The vehicle must have the front bash plate removed and the crank turned to find the timing mark. The mark on the crank pulley is on the farthest pulley back. Where the pulley runs around the front of the timing case it can be hidden from view if it is on the side or the top. The way I did it was put a socket and ratchet on the crank pulley and turn it down towards the bottom as I was looking upward then marked it with liquid paper. I then put a light up near the crank and got a mirror and turned the crank until it lined up with the TDC mark on the timing cover. This TDC mark on the cover is a slot mark at the 12 O'clock position. You cannot visually see it from the top or the bottom without a mirror. When you remove the gearbox go back and check that this mark hasn't moved. Once this was lined up I turned to the flywheel. On the front of the flywheel (gearbox side) there is on the outer circumference just where the ring gear runs a half moon dimple about 1 cm in length. Mark this with the pen. Then turn the flywheel over and look at the back. You will see a section where there appears to be missing teeth. This is the pickup. Now we have checked the crank mark and it is still in the same position. The dimple mark facing you on the front of the flywheel now goes on lined up in the 6 o'clock position. Pointing straight down. The pickup is obviously set on the flywheel so it will end up at around the 12 o'clock/1 o'clock position. Get it wrong as I did and the motor won't fire. Whilst your in there replace the rear main seal and the spigot bearing too.

We had that problem last year a long way from home, Horseman. Our '99 Td Jack did the clutch and then the (very small town) mechanic could not align the fly wheel over the next ten days, even with the help (via phone) of GM dealer mechanic. We had to have it brought home on the back of a truck with the CT being towed by same truck. That was a very sorry sight, indeed along with a good holiday being wrecked.

hey guys could i clear a couple of things up.... just that I got a mate looking at buying a 98 diesel jack right now. There was a shape change in 99 right??
Did the engine change too or is the 98 he is looking at still come under the recall? (if its the same engine)..

He took it for a test drive this afternoon at the dealer. Apparently billowed a lot of smoke on idle and whilst driving (white/grey smoke) for 10-15 mins then finally settled down and acted like normal...

I just wanna know if the recall apply's to the previouse model (pre-98) so we can ring holden and find out if its had it recall.

CHEERS :)
