HVAC Burning Smell

Does anyone know the symptoms of a failed valve cover gasket?

When I'm driving the car I sometimes get a burning smell coming from the HVAC when it's blowing hot air. The HVAC is on auto recirc. When I manually change to cabin re circulation, the smell goes away. The same thing happens when I turn the hvac off.

I checked under the hood once to try to smell something after I parked in the garage but didn't notice anything. BTW, it's been single digits weather around me for weeks.
