never put a gauge on, but I would guess that any would be an indicator of a problem with the PCV system.

Decades ago a PCV tester gauge was available. It was placed on the oil filler cap OPENING and measeured crankcase pressure/vacuum. It had a good/bad scale, as I recall.

No longer available, AFAIK.
