Toyota Land Cruiser Engine Problems

YOU don't say if your engine has had a problem or not, but I suppose it hasn't. So I wouldn't concern yourself. If a problem develops approach a Toyota dealer.

NO THERE won't be any adverse effect on your engine, and with sequential vapour injection you won't notice any difference in performance. You can use an upper cylinder lubricant for a little extra protection as LPG is drier and therefore harsher on valves and valve seats than unleaded petrol, but it's a precaution rather than a necessity. Running the engine on petrol once a week will prevent the seals in the fuel system from drying out and hardening.

WE PUT your problem to Toyota experts and they say it is difficult to diagnose without seeing the vehicle or the colour of the contamination to determine whether the contamination is engine oil or transmission fluid. There is no mention of any signs of water contamination in either the transmission fluid or engine oil. Likewise, there is no mention of engine overheating. Toyota's guys suggested the following inspection: remove transmission coolant hoses from the radiator, pressurise the cooling system and check for leaks from the radiator where the transmission hoses were removed. Inspect the rear side of the timing-case area near the water pump. Remove the rocker cover to expose the rear side of the timing-case cover (just in front of timing chain). Pressurise the cooling system and check for leaks.

EXPERTS at LPG Australia say the conversion is simple and successful, costing $1500-$1800.
