  • Positive Crankcase Ventilation is a system that was developed to remove harmful vapors from the engine and to prevent those vapors from being expelled into the atmosphere. It separates liquid oil from the air inside the engine and intake. Oil vapor remains and is burned up in the combustion chamber. Every car has some form of crankcase ventilation, also known as a PCV, CCV, oil separator, and a cyclonic separator.

  • A breather pipe, also called crank case ventilation pipe, allows an internal combustion engine to vent crankcase pressure out of the engine. It is actually a vent pipe.By venting pressure out of the crankcase, an engine's piston rings are allowed to seal tighter against the cylinder walls. This provides better compression and promotes less oil consumption while making more horsepower.
