5 year 60K just ran out then?
Or did you do it a little early? Leak valve cover gasket doesn't sound good. I didn't notice anything when doing ours at 50K. The dealer might be able to slightly torque them, but they should have been to spec at factory and hate to crimp a gasket. It's not major, but will cause misfires down the road.
You got pics on the oil quantity?
