Toyota Land Cruiser 2004 Problems

There are kits available for your Landcruiser. You best bet is to talk to a local diesel engine mechanic to find out the best kit for your application.

Warning lights are not usually checked on cars prior to sale, but I would expect a dealer would repair the fault when it was pointed out to him.

Backfiring in a vehicle running on LPG is usually a result of the air-gas mixture igniting in the intake manifold, and it's usually caused by a problem with the spark plug leads. In your case it would appear that an explosion has taken place in the crankcase, probably caused by a combustible mixture igniting. You need to have someone investigate then reason such a mixture might be present in the crankcase.

You’re buying a high mileage car so be careful to check the condition of the engine and driveline and walk away if there’s any suspicion they’re close to worn out. There’s little difference between the Landcruiser and the Patrol, but avoid the 3.0-litre turbo diesel Patrol as it has engine issues.

The Tartarini system is a well-known and respected brand, made in Italy like just about every LPG system is. If you have got a dose of contaminated LPG the system could be gummed up with an oily residue, but you should be able to clean it out. Rather than replace the system I would strongly recommend that you try to fix your problems. Your first stop should be to the installer, if that doesn’t produce a satisfactory solution then go to the system provider and seek their assistance. In your case it’s Global Autogas Supplies (1800 620 945).

CARMAKERS tune their cars to suit the average motorist and they also leave a safety margin with their tuning so they can be confident they won't have problems once their cars go into production. Tuners can tune more precisely to achieve a desired outcome, be it more power, torque or fuel economy, and they can play within the manufacturer's safety margin. By some fine-tuning they can extract more power and torque than a manufacturer would dare do. That means you're running closer to the edge when you install a chip, but that doesn't mean you will have a problem. Your best course of action is to choose a chip maker with a long-established, good reputation for doing reliable work, and perhaps with some sort of warranty. Then ask to speak to other owners who have had the same chip fitted to their cars.

I WOULDN'T expect the hopping problem to be fixed by replacing the clutch, but it may fix the problem with first and reverse gears. It sounds as if the clutch is not fully disengaging, which may mean it is worn. If you haven't replaced the clutch before, it could be due for replacement and I would take the advice you have been given.
