Is it possible for a lifter to only make noise at 3000plus rpm and be faint and not consistent more like a rattle or a spark knock? 5.3 07 flex fuel im not in denial just doesnt sound like any lifter noise i heard on any videos i watch not even close...

im looking to find out if a lifter will only make noise when being revved very faint i watched youtube lol im not in denial its a liffer its just not a consitent tap and posible could be a rattle or a spark knock i just did a tune up and it cleared the tracton light and others i cleared the engine light with a pocket scanner and it hasnt come back on but the dam tap is still there i dont want to waist my money
