ok i was replacing the head gasket on a 94 LS and while taking the head off i broke this plastic pipe running from this plastic piece in the middle of the IM (mounted on a flange between two of the intake runners) straight down. At the time i just thought it was an wierd connection so I ended up just breaking all the plastic out of the hole and running a piece of tubing from the port on the IM to the conection on top the cannister below the IM. Was this "connection" i destoyed actually the PCV vlave? if it was what will i need to replace it (besides the valve)?
