N57D30 / N57 Engine Noise / Tap / Misfire like - Running and up in Revs

N57D30 at 325000km - holding engine up in revs I can hear something similar to a misfire / tapping sound, more like a misfire I would say.
Might be normal sound of this engine just a bit more loud than others I have heard.

@@Mad9john Can be an injector. Mine all 6 are new but can still be one makes noise under load. Try to change oil with 5w40 instead of 5w30.

Exista un sunet dubios.
De curiozitate, are momente cand scade in ture?

[@GigiBeleaDK]

Sunetul ? Nu , il aud mereu cu turatia motorului. Scade din intensitate, dar in urechile mele e mereu acolo :)

@@GigiBeleaDK Atunci este extrem de posibil sa iti trepideze capacul ori vreuna din anexe. Plus ca unele din variante au avut ceva lipsuri la capitolul insonorizant.
Departe de mine gandul de ceva mai grav.

@@crististoica9755 Ce e drept nu am incercat sa il tin in ture fara cureaua de auxiliare ... poate sa fie pompa de servo , alternator sau ceva de pe linga. O sa vad cand schimb alternatorul daca se aude tot asa fara auxiliare.
