Crank Case Pressure Test on ‘06 XC90

[bfry]

Took car to a shop to get looked at…

Crank case pressure test supposedly came back as:

-4, -3, +.6 KPA

Seems like I replaced the PCV system yesterday - did myself btw, but looking at the paperwork it was 40k miles ago.

Came home and ran glove test = strong suction.

How do you get a positive outlier, the +.6, but have good suction on the glove?

I trust the shop, but am I missing something?

Thx

Forgot to mention that there are no symptoms, car was in for something else and decided to have them do a “general” check…
