PCV issues continue

[Abdullah37]

PCV is still buzzin after 3 changes.
I was advised that the cause is bad valves/O-rings/Seals
I already changed the breather hose valve and o-ring
The oil pipe is leaking slightly and apparently its not that hard of a job so I am planning to do. Another similar situation is this "John Guest" easy access and leaking slightly.https://www.scuderiacarparts.com/.../catridge-assy-john...
and last advice was the PRESSURE RELIEF VALVE recommendation.
No clue how or where to access to do this.
not sure either what's the difference: https://www.astonmartinbits.com/.../5-V8-Vantage/p... - - https://www.astonmartinbits.com/.../5-V8-Vantage/p...
Any other o rings or seals that can be easily changed to ordered while am at it?
Last important point is if you guys can shed a light on how serious or worry free having issues with PCV buzzing (old one didn't buzz but it was factory for the car from 2007)
would a catch can make life simple or i would still need to figure this out

I cannot see how the oil pump pressure relief valve would affect the PCV. I assume you replaced all of the PCV valve system?

Both PCV valves, both check valves and the pressure relief valve?
