Many Breather Choices

Response to PCV options please

PCV system was just one of the schemes used for crankcase breathing during the 60's.

Variations from a simple breather to full manifold vacuum from the crankcase or PCV systems or some combination.


Choices are based on available access points:

1. Vacuum via 3/8" line from carb, carb spacer, manifold, exhaust bungs or vacuum pump?

2. Crankcase via valve cover or spacer, oil fill, manifold, fuel pump plate, oil dipstick, oil pan, hollow bolt.

One of group #1 and one or more of #2. The more choices for #1 and #2 the better as it allows system choices. Certain systems are functionally better and some are just easier(i.e. tubing complexity).


Oil fill could be via the fuel pump plate or an air/oil separator with return line.

Figure out the choices for access points and design from there, ping me for ideas.
