Hello, if you're hearing a knocking noise, damage has been done. Sure, it could be an oil pump concern, but it could also be the wrong oil grade being used (should be 5W20), an inferior or restricted oil filter, some other kind of internal engine concern, or just a worn engine.
You definitely could use a professional assessment to see what's going on here!
