why do I smell Anti-freeze from exhaust pipe, tail pipe?
re-built cyclinder heads and replaced head gaskets, etc.
How long ago was the work done. If the vehicle had blown head gasket it probably sent antifreeze into cylinders and thru exhaust system. Antifreeze would coat the inside of your pipes and take a long time to burn off. It would also contaminate the oxygen sensors.
