Ok, I am kinda new to this site as well as the whole car thing (bike mechanic), but I am trying to get into it! Anyways, my brother has a 94 civic hatch with an LS/Vtec swap (B18A1 bottom with GSR head just to be exact), it isnt tuned by the way, and hes more into the looks and being able to say hes got LS/V than anything. He was driving it and it started making a screeching sound. It is not the belt, it is over around the throttle body, i think, but it is so loud and high pitched that it kind of echoes off of everything on that side. The only time it doesnt make the sound is when its at idle and just off idle, otherwise, no matter what we do, it still screeches and get louder and faster sounding as the revs increase. Any ideas??? Thanks for ANY help!
