Time for a new or rebuild engine. Gas in oil is bad piston rings. Having to add anti-freeze and white smoke means blown gasket(s) somewhere or cracked head(s) or block.
On the vortec motors gas in the oil is a sign of a bad fuel pressure regulator. As for the coolant loss u got me.
With oil smell like gas....just thinking could it be a Leakey injector....the antifreeze maybe intake gasket..please your information and input will help me out..thanks

With oil smelling like gas you have either a bad head gasket or intake gasket, with the white smoke it can be either burning oil, burning antifreeze, or a combination of both. If you put your hand by your exhaust and then smell your hand does it smell like oil or antifreeze? Either way your going to need to rebuild the motor or get all rings and gaskets replaced. But once your oil goes milky its best to rebuild the motor.
