Brought my car into the dealership to fix a door lock problem and the tech found out I had a oil leak. They replaced the valve cover gasket and the total was $1100 + tax (I'm out of original warranty). Fortunately I bought an extended warranty from coverageone few months ago and I only needed to pay the $200 deductable. I looked at the invoice and it took 6 hrs to replace a $100 gasket/bolts. So ask you tech to check for oil leak if you are near the end of your oem warranty.
