My car engine makes sound when I drive between 30 and 100 km/h
The noise seems louder when I drive downhill or without acceleration. The noise disappears when speed increases to 100km/h and above. I changed the belt tensioner and the noise is still there.

I found the engine oil pressure is higher than it used to be.
