pvc valve

[David J]

Not so sure a PCV is a good choice on early - stock motors

Something to consider . If your 36 motor has not been converted to a modern rear seal you will be sucking crap from the clutch housing into your motor . Plugging the front vent on the pan will actually make this worse . Not plugging the front vent will let your motor suck dirt-dust in to mix with the crap from the clutch housing . Crappy choice in my book . Doesn't really matter if you do or don't use the rear pipe on this subject as the entire rear seal is a MAJOR air leak .The old pipe from the oil fill pipe to the air cleaner is as aggressive as I would get with the PCV idea on a rear sealless motor . This of course is meaningless if you have a good rear seal adapted to your motor . I don't use one myself .

i had a 64 GMC pickup with a 305 E V6 it had the PCV valves under the valve covers threaded into the heads, so if i blank off the vent in the oil pan and put one of those GMC pcv valves into the intake that would work?

x2 or x3. And don't forget to wrap a filter or fine mesh around the front crankcase vent to reduce the amount of stones and other road debris inhaled.
