Hello Darrell,

I don't know if you have completed your PCV installation, but I have just installed a PCV valve on my 1957 (with 292 and 2-barrel carb), so thought it might be similar to yours. My carb has the 4-bolt base, but the procedure would be the same for the 3-bolt base if you decide to drill and tap the intake manifold as I did.

I used a T-bird valley pan that I bought on Ebay that had the existing vent hole and baffle plate under the vent to accept a grommet and PCV valve. The PCV valve I used was for a 1966 Fairlane with 289 engine (bought from Rockauto). The PCV valve has the correct flow direction for installing the base in the grommet and then venting upward towards the intake.

I drilled and tapped the intake manifold just behind the carburetor base, using a 1/8" NPT pipe tap and then installed a 90 degree fitting to accept a 1/2" ID hose from the PCV valve and this allows a very short hose connection to the PCV valve. The 1/8" pipe size seems to be adequate for the PCV flow as I have driven the car and taken it up to high road speeds and everything seems to perform well. I made a cover plate from 1/8" steel to cover the old road draft tube opening on the lower block.

Several things I have noticed since the installation: As others have mentioned, the "gassy" smell in the garage after driving the car seems to have gone away and the underside of the engine stays much cleaner and drips have all but disappeared from where oil spray had collected with the old draft tube.

Good luck with your installation.

A few years ago I got some y-block stuff out of Kelly's Auto Wrecking, south of Arlee. Real good yard. They might have something. Kelly's Auto Salvage

Marc, can you get me the ID Number off this manifold? Im looking for an ECZ9425 B

Ok Charlie, I will consider that option. I guess I need to see what carb I have and go from there to find a spacer that might work. Im considering going that route and saving up for  Mummert Intake.

I don't know if there is but there are aluminum spacers that could be drilled and tapped for a nipple.

Does anyone know if there is a three bolt carb spacer available with a nipple in it that would work for the pvc convrsion?
