My car is producing white smoke on cold startups also missing after heat-up spark plugs adopter also installed on 3 plugs MY mechanic said that it is head, gasket and rings problem and it needs an overhaul. I searched on the internet and it is really head gasket problem but the reason I am posting here that I can trust Pakwheels more than I will tust a mechanic no matter how famous he is. So can you people help me with that? And what will it cost me? Mechanic said that Head is weak and overhaul may take around 8k max.
