PVC valve for engine with OAI
My 71 W30 build has repop aluminum intake from the parts place which is cast from original molds. I will be doing away with the distributor vacuum advance switch (since I don't have one and they are damn near unobtainium) and using that port in the manifold for heat sensor for my under dash temp gauge. There is a large vacuum port next to that that is for the PVC valve. Since this car has the OAI system and the plumbing on both valve covers goes to the breather pan where do I route the PVC plumbing ? I'm confused Thanks for any help !!

FYI, I seriously doubt the repro W-30 intakes are cast from "original molds". If you look closely at the "OLDSMOBILE" logo on the front of the intake, you'll note that there's a slight ridge around it. There's one repro mold used to cast both the "OLDS" and "OLDSMOBILE" style intakes with a plate that is changed out depending on which type is being made.

Joe thanks for the info and I've looked at that manual till I'm crossed eyed. The shading where lines over lap on them is somewhat confusing. On the intake I'm just quoting the sales tech at the parts place. I don't doubt what you're saying a bit. Anyway this build is a clone for me to drive and enjoy, do cruise in's, and a few local shows. Nothing more. Thanks again for your help
