    Toyota LandCruiser: dual fuel malfunction

    Toyota Toyota Advice Toyota Land Cruiser Toyota Land Cruiser Advice Toyota Landcruiser 2004
    We own a 2004 Toyota Landcruiser 100 Series V8. It has done 170,000 km and is on dual fuel. Driving into a country town last week it backfired, which is does occasionally when on gas. But this time smoke billowed from behind so we pulled over. When we got a mechanic he found there was a 50 mm hole in the right hand side of the block. Are we looking at a major malfunction in the construction in this otherwise very reliable vehicle?

    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.
