The Importance of an LS Valve Cover Breather

As a car enthusiast and mechanic, I have seen firsthand the impact that a malfunctioning or missing valve cover breather can have on an LS engine. Many people overlook this small but crucial component, not realizing its importance in maintaining the overall health and performance of their engine.

First and foremost, an LS valve cover breather is necessary because it helps to regulate the pressure inside the engine. As the pistons move up and down, they create pressure in the crankcase. Without a breather, this pressure can build up and cause oil leaks or even damage internal engine components. The breather allows excess pressure to escape, preventing potential issues and ensuring proper functioning of the engine.

Moreover, a valve cover breather plays a significant role in maintaining air quality inside the engine. It filters out any impurities or contaminants that may have entered through the intake system or other openings. This helps to keep the engine clean and prolong its lifespan.

Additionally, a properly functioning valve cover breather can improve fuel efficiency. When there is too much pressure in the crankcase, it can cause oil to be pushed into areas where it shouldn’t be, such as the combustion chamber. This results in oil burning and ultimately decreases
