If you are looking at the engine, on the left hand side valve cover there is a 1" black hose hooked to it by the firewall. Follow that hose up under your TBI to where it goes into the intake manifold. Where it connects to the manifold is your pcv valve. I moved mine. I think i used a 3/8 brass barb fitting in place of the pcv valve. Took the other end the 1" hose and cut it off just above where it flares out to go into the valve cover, and i used a pcv valve from a 92 cavalier 3.1. The body of the pcv valve slids right into the valve cover and you use the hose to hold it in place
