Common issues with Volvo PCV Systems:

There are a couple of things that get overlooked in the PCV system issue. The lifespan of PCV components varies widely based on operating conditions.

Usage: The PCV system likes to be used at higher RPM for long periods of times (like a trip on the freeway). It also likes higher temperatures to help vaporize the negative contamination in the oil and burn it through the PCV. But in the other direction, a car that is used in a cooler environment and shorter distances will load up and plug/fail the system rapidly. We have an employee who completely rebuilt their PCV system in their daily commuter about every 18 months, due to the cool/damp environment and a 7 mile commute on surface streets.

Wear: The contaminants in the oil are volatized and burned up by the PCV system. But, the amount of blow-by in an engine (the primary source of contaminants) changes dramatically as the engine goes through its life cycle. So, the amount of contamination the PCV system is required to handle in a 300k engine is dramatically different from the contaminants in a 100k engine.

Final: Kind of a combination of both of the above topics. The majority of contamination and plugging in your system happens during warm-up. This is why cars that are used for short distances need so much more PCV work. So you can’t really measure life cycle of PCV components in miles, but they are really measured in key cycles (temperature cycles).
