[Tigers] PVC Valve

                The only information I have on the internals is from Bob
Mannel's book pg. 4-42

This the early style PCV valves which are serviceable.

The later style with the hose fitting are not serviceable so not sure of the
internal components.

You would have to cut one open to see inside.

All this discussion about PVC valves has brought to mind a question I have
had for some time, and that is, what are the differences in all these valves
on the INSIDE.  They have all kinds of different external attachments, but
what is 

 

different about say a 289, 302, 351, 352, etc, etc. on the inside.  They all
work with the vacuum of the engine, varying the volume of vacuum (air) going
into the engine depending on engine rpm burning any blow by.   Anybody have
any actual specs on what is inside any of these?
