Can clutch fork vibration cause air into system thru rod

[nissan3227]

Nissan 94 truck- The clutch fork is shaking and I have to bleed the system every 3-4 days. I can't find any leaks. I've changed the master and slave many times with all different brands... I'm trying to verify If it's just The quality of parts these days of the master and slave or if I need to put in a different pressure plate....

When I touch the push rod to the slave cylinder I can feel the vibration there as well.

I've never had this problem before with the Original factory Nissan pressure plate...

I would think the vibration would bleed it easier
