Could I run pcv of the intake manifold instead of the carb ?

And internal pressures cause seals and gaskets to blow out. That's why every engine, transmission, and rear axle has a vent.

Not TOTALLY true (I'm being pedantic...), my '53 Buick doesn't have any rear axle vent.

I figured this out after I had it rebuilt and it blew out the pumpkin gasket. Apparently, the old seals were felt, and they must have let enough pressure by that Buick got by without a vent. I am now running a vent tube through a brake bleeder screwed into one of the back cover bolt holes (which is open). I put an inline fuel filter at the end and now it's vented.

Just thought I'd share a weird story...carry on! :)
