Harmonic balancer was replaced under warranty. No visual indication that oil pan was damaged. Can't see directly behind balancer - will have to remove to do through inspection. Oil is leaking either from seal between upper oil pan and block directly behind balancer or from bottom of crank seal. Pics would be helpfull before I remove balancer.
