PCV System

I have a 95 350 Chevy converted from TBI to TPI and some where i got lost with the routing need some imput . This is what i have set up right now not sure if it is right . Drivers side valve cover has one hose with a tee connected with the CCP also and the hose comes from the front of the throttle blade . The pass side has the PCV hose connected to the back of the throttle body .

Re: PCV System

On my car, the driver's side PCV goes to the port near it on the intake manifold.

The passenger side PCV goes to the larger top hole on the passenger side of the throttle body.

The Canister Purge line goes to the smaller lower hole on the passenger side of the throttle body.

The other large holes on the bottom of the throttle body are for the radiator coolant to pass thru.
