i have a hose that runs from the intake to the valve cover on the driver side of the motor. it has kinda like a filter i guess u'd call it at the end that goes into the valve cover, what is this hose for? its making a noise and bother me, kinda like i guess the filter part is loose maybe? and kinda feels like the trucks not as powerful or however u wanna say it, cause used to its spin nicely from a 20 and now not as much
