Default Will atap show bent pushrod or floated valve?

After autotapping my car due to its lack of performance lately, I lost 2mph at the track thought I had a bent pushrod or a floated valve. I made about 10 runs, my o2's were between .90-.89 for the first two with no knock retard. Then the next three runs o2's dropped to .87-.88 but still no knock retard with 25 degrees of timing. Will atap show a bent pushrod or anything of that nature ie: knock retard?

AutoTap might show a misfire, but you better get out the compression tester and leak down tester out to check for rod and valve problems. Have you pulled the rocker covers yet?
