The process of modifying the crankcase ventilation system on a 6.0 Powerstroke diesel engine is undertaken to mitigate issues stemming from excessive crankcase pressure. This modification generally involves rerouting the crankcase gases to a location other than the engine’s intake, often venting them to the atmosphere or through a catch can system. A common example involves replacing the factory crankcase vent tube with a longer hose directed away from the engine bay.
Implementing this modification is often considered beneficial for several reasons. Excessive crankcase pressure can lead to oil leaks, reduced engine performance, and potential damage to seals and gaskets. By venting these gases externally, the pressure is reduced, potentially preventing these issues. Historically, such modifications have gained popularity within the diesel performance community seeking to improve engine longevity and maintain optimal operating conditions in modified or high-performance applications.
