What is burning? Oil or coolant? If it's coolant, check the heater core hoses near the back of the engine/firewall, the clamps might be loose or the hoses need replacing.

The plastic elbows that go to the heater are prone to leaking. It's possible that the flushing process has caused them to fail. They are cheap to fix and will leave you stranded if they fail.
