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.

Causes of oil to be intake on 2004 Chevy cavalier?

I would suspect something along the lines of a PVC valve that is causing oil to be in the intake. The PVC valve equalizes pressure inside the engine, otherwise as the pistons move down there would be compressed air inside the engine. The PVC valve is a check valve, it only allows air to flow one way. If it were clogged with trash and stays open then oil could get to the intake.
