Knocking sound


So when im sitting in my car with it at idle sometimes it will make a knocking sound. It comes and goes but it sounds like its coming from the transmission area and it goes away when i engage the clutch. It started after the cams cause i guess the car shakes alot more idk. Any ideas as to what it could be?

Its deffinatley the throw out bearing. My car does it, did it real loud before i replaced the throw out bearing. the rough idle just brings it out. Nothing really to worry about. As long as it goes away or gets quiter when you engage the clutch.


(Throw out bearing is part of the slave cylinder)
