Hopefully someone can help. Have a fiat doblo 1.9 jtd 2004 model and have had a problem with it drinking 5 litres of oil in 2 weeks. Have had the turbo completely rebuilt, new crank/rpm sensor , cleaned the egr valve and still loosing oil. The car is blowing blue smoke so I'm guessing the oil is burning off but where I don't know. The engine fans don't work unless you disconnect them from the sensor and have them constantly on. The engine was cutting out but changing the rpm sensor stopped that. We have tried everything and it's still drinking the oil can someone please help any input will be good.
