The engine was knocking about 3 weeks ago and it was determined the belt tensioner failed so i changed that. I didn’t change the belt at that time. Now a few weeks later the engine is knocking but I can’t ID where it’s coming from. Its definitely a knock (not a tick/lifter) and is present at idle and while driving, but is inconsistent in intensity. Any suggestions on where to start to diagnose?
