Jackaroo & LP Gas

Hi Peter I have a 2001 jack and i too wanted to put in gas but was told by a well respected gas conversion shop that the jack's have to do at lest 150000 k's before they would concider putting gas on because from new the seats and valves are not hard enough and they seem to be ok after 150000. He also said that the rodao's are ok from new because they are built somewere else. The chamber in the head gets much hotter running on gas then on petrol.

the Problem is the heads cracking between the exhaust and spark plugs.
You got to weld up the head the head then re-machine the whole lot.
Its not pretty.

i asked 3 of our local fitters for prices 2 i knew and they both said they wouldnt touch a v6 jack.
the 3rd i didnt know said it would be around $5000 i said wtf he said around $2500 for gas installation and another $2500 for head work.
jacks happy now sitting out the back yard.
cheers.

Is there a difference between Jackaroo and Rodeo heads?

I thought they were basically the same motor except for the ECU chips

I have also had no luck getting a gas conversion done on my 94 model Jackaroo.
I have spoken to literally dozens of suppliers and installers all over Sydney and have had lots of different stories, but not to do with head problems. Mostly they say it's that the engine's management systems can't cope with the gas. I thought the Flashlube attachment was supposed to overcome the valve seat problems. I've been running an old '82 model on gas for 15 years, with a Flashlube kit attached. I'm told that all fuel injected Jackaroos are unsuitable for gas conversion. I'm bitterly disappointed not to be able to convert the '94 model and am now thinking that I will sell it. It's an excellent vehicle with only 86000 genuine kms. If anyone's got any more clues about converting the fuel-injected Jackaroos, I'd love to hear from you.

Before you go running around in circles, may I suggest you contact
Mr Peter Linahan at LPGAustralia on +61 (2) 9319 4733 and ask him officially whare you stand with each comment.
He knows the facts and, what he doesn't know, he'll point you in the right direction.
Also visit here
to find the inside goss on LPG.
I recently converted my Mazda E2000 and he told me what, where, why etc etc.
I now have the right system installed, by a reputable installer, and haven't looked back. I actually giggle everytime I see the price at the pumps.
