Cam seals blew 2 times, oil drained the second time was told it was fixed, drove to Fl and 1/2 way back blew another seal brought to GM dealer replaced cam seal again, AC seal, $888, drove a bout a week oil pan started leaking $668. I was told its okay to drive. They added oil as needed, but the oil consumption got worse. I brought it back and now it had a cracked piston, blown crank seal, recommended engine replacement another $7900!
