What color was exhaust? If white....then u blew a head gasket. You may have antifreeze mixing with gasoline....providing the white exhaust
HAVE THE COOLING SYSTEM PRESSURE TESTED FIRST..THEN WE CAN GO FROM THERE....
Sounds like oil leaking onto the exhaust manifolds. Sounds like the valve cover gaskets need to be replaced. Also check your engine oil level since it has ben leaking, keep the oil level up to where it is suppose to be.
