Okay, my 2 cents
Troubleshoot, ( prefer to go to Holding area ), preparation that include the Overweight ldg Cx, approach, write the problem and Overweight Landing on Maintenance log book
Troble shoot ? Holding? Maintenance Log book?
Man, you are on single engine!
Declare Emergency! Try to stay overhead or near the airport (ATC) prepare for approach and get the dam thing down..
