my car shoots out deadly white moke out of the tail pipe nd i was wondering what t could be .. i had people tell me its thhead gasket an others tell me its the rings....please help me out on this

White is usually antifreeze that is getting in the combustion chamber. Usual culprit is a head gasket. If the rings were bad, ususally you will see blue smoke - oil that is blowing past the rings and getting into the combustion chamber. If you know someone who has a shop or someone who has equipment that would be willing to help you out, there is an easy test. Use a CO sniffer and put it in the radiator neck (remove the cap). If it smells CO, head gasket problem. Good luck.
