Holden Rodeo Diesel Problems

Seeking the help of a diesel engine mechanic is a good idea, they often have greater expertise on diesel engines than mainstream dealers and can make repairs at a lower cost to you.

That's not just bad fuel economy, it's bloody appalling. It would appear to be running very rich from your description, so I would fit an oxygen sensor if it doesn't have one. If it does it would appear that it's not working.

It would be possible, but I wouldn’t recommend doing it, as there’s too much work required. I would recommend converting it to LPG, you’ll get the savings and it won’t cost you anything like as much. Use a good quality sequential LPG injection system, and check the general condition of the engine before making the conversion.

There are a number of LPG systems available for diesels, but they’re different from those we’re used to on petrol engines. In the case of the diesel system an amount of LPG is substituted for diesel, the engine never runs on LPG alone, and the effect of that is to increase power. The idea is then that you back off the throttle and save on fuel, but some people make full use of the extra power and can suffer engine failures as a result. I would urge caution and certainly urge you to talk to other owners who have done the same conversion you are considering to get their experience. It’s also crucial to have an experienced installer do the work on your car.

IT DEPENDS what you regard as incredibly thirsty. Four-wheel-drives tend to be thirsty. They're heavy and have to drag all that extra four-wheel-drive gear around, and the Rodeo's petrol V6 is a 3.5-litre unit. If fuel consumption is a key consideration for you, try a diesel. Fuel consumption will be much lower, and you won't lose too much performance.

The 3.5-litre Rodeo uses more fuel. I recommend the Toyota. Consider a diesel if you are concerned about fuel economy.

Holden's service people say the problem was fixed with the introduction of a new seal last year. Holden's response was: "Vehicles undergo a continuous cycle of product development." To this end, the O-ring on the Jackaroo Turbo Diesel model was revised, and last year a procedure was developed in order to allow fitting of such by Holden retailers, as required. "To our knowledge completion of this replacement has resolved any issue." If you have had the new seal fitted and are not satisfied it has fixed the problem I recommend you return to the dealer and register your complaint.
