At the first oil change in my new 2006 GMC sierra, I found pieces of
metal (assembly from the engine) attached to the magnetic drain
bolt. Such is usually symptomatic of a defective bearing or something. No problem as of yet with the vehicle, but registering this observation. For record purposes. The attendant at the place where I got the oil changed said my vehicle was the fourth one he's observed with the same kind of metal pieces.
