My mehran is giving plumes of smoke with a bluish tinge upon startup. I have recently gotten an oil change and put in Shell 20W-50 in it and as it appears same is being burned. Top speed for the car is around 80km/h but acceleration seems to be satisfactory.
So I believe its time for an engine overhaul.. What should be the cost to overhaul this engine, assuming most parts have to be replaced.. Also is there any honest and reliable mechanic that you can recommend for the task.
