I think mine is a piston slap issue. Currently at 80K miles. I just started my car for the first time today and it didn't make any noise. It only happens when it's cold af. Ambient was about 60F and thr car had been sitting all night. I'm not too concerned. I've read these engines have loose tolerances to reduce friction and extract as much power as possible. My car sees redline at least once a day.
