I have a 98 deville and i have some smoke coming out the back tail pipe. It smells like antifreeze not oil. Dont know what the problem. Need help...

Do you have any overheating or running at higher than normal temperatures? If it smells like antifreeze, the only way I know of for that to get into the exhaust is due to a failing head gasket. You can rent a block test kit from your local NAPA or probably most any box auto parts store to test for a blown gasket. Also, have you recently started noticing a loss of antifreeze?

If it smells like anti freeze, you'd better be seated when you hear the price of the repair.
