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).
All engines wear out in time, whether they are running lightly loaded or operating under a heavy load. There is no reason to believe the Landcruiser engine would wear out faster if it weren’t run under load, as the mechanics have suggested.
It’s not normal to get black smoke under acceleration, that suggest it’s being over-fuelled and should be looked into. Aftermarket chips can be worthwhile, but they generally take the engine closer to the limit than does the factory chip, so you need to find an installer who can be trusted to do the job well. I wouldn’t do it on your car until the warranty runs out, and then consider it.
It’s hard to say. If the piston was holed or melted because of an issue with the mixture and the piston failure caused the engine to seize it could possibly be blamed on the LPG, but it’s unlikely that the LPG caused the problem.
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 gearbox is sealed in production and it's not meant to be serviced for "life", but what "life" means is anybody's guess. Oil is the lifeblood of an auto transmission and Andrew of AW Automatics is of the old school, which advocates changing the oil every 20,000 km, particularly if the car is being used for towing. On that basis you would be well advised to have it changed.
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.
While most automatic transmissions today are sealed for life and carmakers say they don’t need any servicing it pays to be cautious, especially when towing as you do. The guys at AW Automatics say it holds 8-9 litres, the service fill is three litres, and you should use Toyota WS trans fluid if its in warranty, and Valvoline Synthetic Trans Fluid if its out of warranty.
There should be a plug on the side of the transmission that you can use to check the trans fluid level. It’s unusual to strip teeth off the crown wheel; we haven’t had any other reports of that problem on the Landcruiser.
