Component or system that failed or malfunctioned: the component that failed was the partial-load ventilation valve, which is part of the engine’s crankcase ventilation system. This valve is responsible for regulating airflow and pressure within the crankcase during partial engine loads. A malfunction in this valve can lead to increased engine pressure, oil leaks, and potential damage to engine components. The component is still available for inspection upon request. Safety risk: the failure of the partial-load ventilation valve put my safety, and that of others, at risk in the following ways: •engine stalling or reduced power while driving, especially during acceleration, which increases the risk of an accident. •in some cases, oil leakage caused by excess crankcase pressure could lead to engine compartment smoke or a potential fire hazard. •if the engine performance is compromised, it may suddenly lose power on highways or intersections, posing a serious risk. Problem reproduced or confirmed: yes, the issue was confirmed. The technician verified the faulty valve during a diagnostic inspection after I noticed performance issues and warning messages. Inspected by manufacturer, dealer, or others: yes, the vehicle was inspected warning lamps, messages, or other symptoms: yes, there were warning signs prior to the failure: •check engine light illuminated on the dashboard. •engine running rough or hesitating, particularly during acceleration.
Just replaced water pump and still need to replace positive crankcase ventilation system hose.
