Hello all, I'm looking for some advice from other G6 Owners on their experiece concerning whats normal and what might be not normal engine noise. Both my son and myself own 2007 G6 Sedans with the 2.4L engine ( yeah, I liked his so much, I went and got one too). On my car, the engine starts making a tapping noise once the engine is warmed up. If you are "old" like me....you would say it sounds like a dirty lifter or maybe wrist pin noise....anyway, I took it to the dealer and they checked it out by listening to it and said that its "rotational" noise, don't worry about. Well, thats all well and good ,but my son's car does not have this noise and both are basically identical ( 2.4,auto trans, etc..). What would you do ??
