Wife's fabulous Equinox 2.4 is having significant PCV pressure, like I can pull the breather line off and it will be blowing out. Already checked the problematic PCV port, and it's clear. Since rings are a known issue I'm thinking the rings are the culprit. Among the Equinox forums it seems the vented oil cap is desirable to prevent blowing out the crank seal, but would it also cut down on the oil consumption? Just trying to keep it going until we can get rid of it, but a vented cap might be a cheap fix if it helps.
