Can lifter tap register as knock?

So I experience lifter tap when my oil levels get low. Its been happening for a couple days so I finally added more oil...now the tap is gone.

But when it was happening I noticed that there was a decrease in performance....turbo would spool but the power wasn't there. So yesterday I put more oil in, nice and full. Drove to work this morning and there's no tap, and it pulls a lot harder than when it was tapping.

So can valve tap register as knock? Or?

Yes it can. Have you datalogged to see if you were actually picking up knock?

No, I haven't purchased a datalogger yet. Going to soon. I'm thinking it did register as knock or something because now its pulling again.

I have an oil leak at the damn oil cooler...haven't gotten around to replacing the housing with my forward facing bracket. Been raining too much.
