High crankcase pressure can lead to several issues, including oil leaks, gasket failures, and potential engine damage. This occurs because the increased pressure pushes oil out of seals and gaskets, leading to leaks and contamination. To avoid these issues, regularly check for signs of leaks and ensure your PCV (Positive Crankcase Ventilation) system is functioning properly.
