Can a clogged PVC damage an engine?

Yes, a clogged PVC (Positive Crankcase Ventilation) system can damage an engine. When the PVC is blocked, it can lead to increased pressure in the crankcase, causing oil leaks and potentially forcing oil into the intake system. This can result in poor engine performance, increased emissions, and in severe cases, engine damage due to oil contamination and inadequate lubrication. Regular maintenance of the PVC system is essential to prevent such issues.
