I know to fine tune the bov you have to back the screw all the way out and then tighten from there. Problem is when i try to tune my cousins car. He has no screw/nut back there. Does anyone know if i can get a replacement one from an auto store? What size it might be? Thanx

theres a spring behind the screw? my cousin backed the screw out too much n was driving around. when he wanted me to adjust it there was no screw there so it must of fell out. Now he gets compressor surge like crazy at low rpms and it does release but only at high rpms.
