Hey All! I keep running into the same search results and cant seem to dial in an accurate answer (or at least one I'm looking for)
Here's the situation:
22R engine temp would not get up to temp (heater blew luke warm)
Replaced the thermostat and then a couple days later was working on a carb issue
and was idling and a very subtle ringing noise appeared.. closest sound I can compare is like a wet finger around the rim of a crystal glass. (A high pitch ringing noise). This is ONLY at idle, not any higher....i.e. 1000 rpm +
Now before you tell me it's a belt or my alternator...keep reading.
There is no play in the WP and fan, no leaking, I took off the belt and spun everything, and the WP is the culprit, but it's still smooth and the sound is coming from the belt pulley metal bell shaped thinga-ma-cover. in fact I can tap it and it;s the same pitch.
Ive never heard a bearing go so high pitched and most post I read talk about a grinding sound etc....
any help greatly appreciated, I just dont want to panic if I dont need to
to.
