Engine smells like burning oil. Is this the oil pan gasket & how much to repair? on 2006 Chevrolet Malibu

The engine smells like it is burning oil, and the last two times I've had the oil changed it's been 1 quart low. Should I have the oil pan gasket replaced or sealed, if it is the cause of the smell? What is the best way to tell?

WHAT SIZE MOTOR DO YOU HAVE?
I know it's a v-6, but that's all I know.
APPROX 800.00 IF THATS YOUR ISSUE
Ouch! Thanks for the info.
