I have Santro Club GV 2006 with 110k mileage. Recently I am facing 3 problems in my car.

1. When engine is cooled down it starts after 4th or 5th crank and engine makes a slight "bhut bhut" noise before it has to be forced to start especially in the mornings. When it comes to life, the motor has to be revved to get on going, after that, when the car engine is bit warm it runs absolutely normally and cranks at first stroke.

2. When engine starts after 4th or 5th crank it exhausts black smoke first for 5 to 10 sec and after that blue smoke for 1 or 2 mins then throws water from silencer without any smoke. This usually happens in the morning when car parked for about 10 to 12 hours.

3. Few days back I have changed its motor oil but after 1000 KM its oil is too dirty. Its density is fine but color is changed from red to black.

I went to several Mechanics but they are experimenting every time. Please suggest some good mechanic who is expert of Santro and also guide some solutions.
