PCV (Positive Crankcase Ventilation) is an important car engine system that mechanics work with regularly. It helps keep engines clean by managing gases that build up inside them. Think of it like a small air circulation system that prevents harmful vapors from staying trapped in the engine. When someone lists PCV experience on their resume, it means they know how to check, clean, or replace these systems, which is a common task in car maintenance. This knowledge is particularly important because a faulty PCV system can cause engine problems and affect vehicle performance.
