I have a 2002 Chevy Tahoe. for the past 6 months


without hearing exact noise it is hard to diagnose. these vehicles had a normal cold start knocking noise due to the low friction rings used allowed piston some extra movement. when carbon builds up on pistons it gets worse will go away after about a minute running. it does not affect life of engine or performance. i think this may be noise you hear. or possible it is a lifter leaking down and taking a while to pump up
