Bearing worn due to high milage would think. Not good to keep driving will get louder and spin damaging crank. Fix is rebuild or replace engine. Have a shop take a listen

Maybe a hydraulic lifter very hard to diagnose noises over internet so go to shop have them take a listen

I replaced tge knock sensor. The car is running muck better. It still has a slight knock, does the computer need time to fix the timing for it to stop knocking?
