PCV VALVE SYSTEM for 8BA with Early Intake Manifold
- Thread starter V8COOPMAN
- Start date
Decling helped me out on this modification. Thought I'd add a twist as I appreciated his knowledge and Coop's.
Running an electric fuel pump on my Flathead Model A.
I'm a cheap SOB and couldn't see spending $150 on a shorty Speedway pump stand.
The diameter of the Henry stand at the X (first pic) is close (within a thou or two) to the bore of the 1" thick carb plate. The casting in this area is off a couple thou. Second pic is where I hacked off the Henry stand. Chucked it up in the South Bend to clean the cut up. Third pic is the new shorty stand pressed into the plate. Added a little anerobic sealant for good measure.
Now to add the PCV adapter.

Man, I love 'thinking out of the box', especially when the workmanship is at least as good as the thinking. That's SLICK! And thank you for the kudos!!

Be nice if you could buy akit with all the "stuff" you need to make this PVC system we people that live in foreign countries Like Vermont, can;t find most of it.

I don'r uz the fuel pump (in tanl electric_ so I could use an earky fil pump unit and make the riser. But!!?????

A neat but complicated engineering project.
On a wet sump engine, I have done the crankcase breathing much simpler with all stock parts since the mid 50's.
On an 8ba block I use an early (pre 49) manifold and just cut 1/2 inch off the top of the fill tube. I leave a 1/4 inch wide tab the height of the manifold deck to keep the tube from coming out. I use an original early oil fill/breather stand with mesh filled cap.
Just like factory. No smoke or oil puking up to 7K rpm.

Why didn't you run the PCV into the bottom of the intake manifold instead of routing a tube outside through the breather and then back into the manifold?
I'm not trying to be a pest but thinking about tapping directly to the bottom of the intake manifold so want to make sure there isn't something I'm missing.

'Cuz one of the big ideas here was to be able to change or service the PCV Valve WITHOUT REMOVING the intake manifold. If I'm understanding what you describe, it looks like the only way to service the PCV Valve would be to remove the whole intake manifold. The little bit of tubing that is exposed in our iteration is minimal & rather pleasant to look at, eh?
