HI have a problem with the engine isuzu. During the day, the need to pour the liquid cooling system. Leakage can not see but I have the impression that the fluid burns with fuel. It is possible? After an hour of work at full capacity can not see anything in the exhaust gas, but when the engine is slow to idle for about minute you can see white smoke. Water cooled turbo is proven and effective. Is it possible that the fluid was getting up for the combustion chamber and the cooling system was not evident bubbling? Sometimes show up but slightly. But after closing the radiator cap can not see that something was going on in the coolant expansion. Remove the head? Or maybe a different reason? Sory for my englisch Thanks in advance
Do you have EGR cooler/s on your engine, They could be leaking into your intake manifold and burning it ??
Don't hunk the 4jx1 has an egr cooler... I'd test the coolant for combustible gas... More than likely the head gasket or worst case, crack in the head... That said, those Isuzu lumps are pretty robust.
