You probably have an oil leak somewhere around the top of the engine. Valve cover gasket, leaking head gasket. When the engine warms up, it cooks it off and you smell it.

Why would anti freeze leak from exhaust pipe?

A blown head gasket could allow coolant to enter the combustion chamber from the water jacket. The coolant probably is running out the exhaust on first start-up. More often, you will notice the coolant being pumped out of the overflow as the exhaust gas pressurizes the coolant. You should look for this symptom when the engine warms up. Coolant in the exhaust on start-up and then the coolant overpressure overflow from the expansion tank or radiator happening together is almost sure indication of the head gasket failure.

I'm assuming your asking about the coolant purge valve, there is a pipe that runs right above the exhaust manifold, take a 6mm socket and turn c/clockwise half a turn while you are filling the coolant. Ahen coolant comes out, system is purged. Idle for 20 mins and observe temp and coolant level anyways, cause overheating those engines is not cool at all.
