There are numerous symptoms of a failed valve. One critical symptom is finding a dirty or oily spot near the PCV inlet hose. A failed valve that sticks open may cause a check engine light. The valve's failure to seal positive pressure could also ruin the engine. Additionally, a severely damaged valve can cause oil to blow onto the air filter in some vehicles.
