AoA. My altis 2006 needs a new engine assembly as it's reducing oil and frequent over heating issue. The mechanic says it's better to replace the assembly/ put in a 1.5 litre engine from Japanese car. Can anybody help me out by suggesting which is better to change the assembly or to get a new engine? Plus what would be the cost of both options in peshawar/pindi as it's quite expensive here in fsd. Waiting for positive replys thank you
