It's now 1 month and 800 miles after installing my JRSC and today I heard a clicking sound coming from the engine. I popped the hood and tried to stick my head in, it is coming from one of the pulleys, hard to say which one but most likely from the SC pulley. It is louder during the first couple minutes when I start the engine, than it gets quieter but never goes away:
click click..........click click..........click click..........click click..........
click click..........click click..........click click..........click click..........
click click..........click click..........click click..........click click..........

I checked the belt it looks normal and tight. SC and everything else works fine. Can it be a sign before breaking down? Any ideas?
