Input bearing
 

I just put a new 1.5L into my 1993 Civic, but the problem now is that I think/know i need a new Input bearing. It makes tha sound as soon as the car is started and will continue to make the sound the whole time the car is running. The car still runs very stong, but This sound is driving me CRAZY! if you know what i am talking about please let me kno that you think it should sound like and How long it will last they way it is. Or do i have to FIX it right away?:(
