My engine manufacturer has recommended that I use the large (3/8 in.) vacuum port on the carb baseplate for my power brake vacuum cannister, and find an alternative port for the PCV valve. I have been using that port for both functions. The car runs great but uses more
oil than I'd like. So, this is his suggestion to reduce
oil consumption.
The only other full manifold vacuum port I have is a 3/16 in. port on the baseplate. Would that be adequate for a properly functioning ME Wagner PCV valve? Or do I bite the bullet and have a port machined into the intake manifold?
Or, was the advice to find another vacuum port a questionable suggestion in the first place?
I get 13" of vacuum at idle and drive the car on the street only. The engine is a new installation. Brakes work fine although I understand conventional wisdom says I need 18" vacuum for proper brake boost.
All help appreciated!!!
