1957 adding PCV valve system

[EdBelt]

Hi, my Thunderbird has a 292 y block with the down draft tube on the drivers side. I am interested to know if anyone knows of a way to add a PCV valve system without replacing the valve covers or putting in a different valley pan. I read that you can block off the bottom of the down draft tube , and drill a hole in the canister above the mesh element, insert a grommet and PCV valve. Then run the hose up to the vacuum port on the rear base of my new Holley 2 barrel. Has anyone tried this , or have any other suggestions as to how a PCV valve can be added on a budget? Thanks

Your title "1957 Ford Thunderbird Down draft tube" has been revised to summarize what the post is actually about. Also you do not need to include the make & model of your car in the title.

I believe what you described could be done. Another option is to visit the usual vendors sites and take a look at the PCV conversion kits they sell. Using a kit is likely to present a neater appearance then the other approach.

This is the kit for the 2-barrel. It includes instructions.

PCV conversion kits includes gaskets. PCV valve in kit is metal, replacement is plastic. Spacer is made from 1/2 thick aluminum

Unfortunately my down draft tube is on the driver's side of the motor, not at the rear of the engine. This won't work unless I change the valley pan. Anyone have another suggestions?

Yup, from what I see on "the internet" the preferred method is to get a valley pan with the rear road draft tube setup. That said, your original method would still work, it just would not look as nice and you'd have a bit more tubing running around.
