2005 Chevy Equinox 6 cyl All Wheel Drive Automatic 45390 miles
my car is making a tapping noise that I can barely hear from inside the car (with windows closed), but is hard to miss when your outside. The car is a 2005 chevy equinox and I have gotten the oil changed every 3000 (w/ in 300miles) religiously. The oil light did not come on and the temperature was in normal range. I have gm service guard warranty, do you think its just a hydrolic cylinder, or could it be a bad camshaft?
