Hello, I have a new car. 1993 Nissan Patrol 2.8Td 381.000 km. My problem is at first start morning the car start easily but White/Blue smoke on morning/Idling problem happens for 5 mins. After 5 mins, there is no smoke and idling problem. I am thinking the problem is because of injectors. I removed glow plugs. and one of them was wet like diesel wet. What can be the problem?
