[FlatJan]

i need to grab out this old thread as i´ve got a question concerning using a pcv-valve on a french flathead.
Actually i´m not sure which system it uses 59ab or 8BA.
the french ones have an 59ab-style breather in the back of the intake, no inlet on the pan (like the 59ab) and a 8BA-Style road draft tube (can be shut off manually).

So my guess for original french configuration with open road draft tube is:
the intake vacuum sucks in gases by the 59ab breather, it runs through the engine and comes out by the 8BA-Style road draft tube. Is that possible?
this would also explain why all french engines i have seen (used ones from the mil trucks) have nearly no oil in the breather mesh filter.

i bought a 59ab navarro intake for that baby. i wanna plug the gallery hole and connect a pcv valve there to run the crank case gases through a tube within the valve gallery to an intake port of the manifold.
Will this work correctly?
