The recall replaced the front valve cover gasket, and redoes the front plug wires, via removing them from their factory installed plastic shield, and installing them loose, and having wire separators on them now.
Its under a recall, so yes, its free parts and labor. Just call the dealership YOU trust, and provide them your VIN # and make an appointment.
If you have already had your front valve cover gaskets replaced by yourself or a shop, GM will refund you (as much as they see justifiable on their end) in full. The GF spent almost $200.00 to have hers done, and GM only gave her back about 1/2 or 7/8 of that I believe.
I replaced mine a long time ago, and don't have a receipt for my gaskets, so screw it. Better me doing it than any dealer ship around here. Honestly, I don't trust anybody else under my hood. Especially these so called ASE certified mechanics they hire at the dealerships. They are about as skilled as the high school kids at Wal-Mart pushing carts in.
