Flathead PCV ????

[derek costello]

In my continued quest to make my '52merc engine run cleaner I am fabricating

a positive crankcase venting system for it. Because I'm going to run duel carbs

I know I will have less vacuum to work with, therefore I have drilled and tapped

my duel-carb manifold for 3/8" NPT fittings in both main channels to supply the

PCV valve with as much vacuum as this set-up can muster! I will be installing

an air intake at the other end of the intake manifold.

Take a look at the pictures and let me know what you think.

Derek.
