You said pulley, do you mean the cam cog belt wheel? and how do you know that? a stethoscope at ears? my guess???? (damage has no limits on machines) 1; it is loose.... 2: the timing belt is loose, (never changed at 60k-90k per FSM) if the belt slips, you can kiss off a good engine. bent valves or far worse. (no limits) 3: the new belt drifts running and hits the cover. ask how and why , i have a 6 point list for that. seen them all.
the honda engine is INTERFERENCE CLASS. the piston chases the exhaust valve closed, (max power and efficiency , is why) and if the belt slips. the piston can hit the valve and bend them all. with possible wrecked pistons, or worse, bent rods. cracked valve guides (wrecked head) and pounded to death rod bearings. ask any engine builder for photos , we have many,, ask.
