The fact that the auto manufacturer's set it up the way they do is an EPA requirement. It isnt permitted to be returned to the atmosphere like it was in the past. Therefore, they route it back through the intake because a catch can that a customer is expected to monitor is not a selling point.Some moisture vapor, carrying trace oil is going to make it thru the PCV. Excess amounts are certainly bad, but not just for the sake of it re-entering your intake.
The amount of reviews justifying the validity of these catch cans also mean that the majority of vehicles out there have the moisture recirculated. Bad although it may be, catastrophic it is not. If it were, these would be OE parts.
The engineers would call it within normal operating parameters, while the internet descents.
Its actual worth is probably better defined by your personal appreciation of the part. The overwhelming majority of us on this forum are without it, I doubt we're overwhelmingly going to experience premature failures.
Most people do not keep vehicles long enough to suffer the long term effects of oil being recirculated into the intake. Regardless, the engine is better off for not having as much or any oil doing that.
