In this video, I show you the location and the proper steps to replace a Positive Crankcase Valve (PCV) on a 3rd gen Honda CR-V.
The positive crankcase ventilation or PCV valve is an inexpensive and often overlooked component. It is also one possible cause of expensive oil leaks and sludge buildup in an engine.
All automotive engines are lubricated with oil and when oil is churned by moving parts, a pressure is produced. Piston rings and valve guides also leak slightly producing pressure in the crankcase. Many years ago, they simply vented the pressure into the atmosphere with a road-draft tube and breather cap. Today we use a positive crankcase ventilation or PCV system to handle this and other tasks.
