my car had got blown head gasket.. took the car to mechanic. He gave two options after opening the engine head.
1 - get new head and new pistons and get the cylinder walls faced with leth machine.
2 - get new engine from shershah
now I am confused what should be the best option. currently the engine is same as stock engine i.e 16 years old. I doubt that another good engine will be available fro city hyper 16 valve.
