This happens on all engines but is a very common issue with modern high compression, high RPM engines. Excess oil in the combustion chamber can even dilute your gas, lowering its octane level. That oil vapor eventually ends up coating your intake valves and burning in your combustion chamber creating carbon buildup. The kit includes easy to follow instructions and factory style PCV hoses and connectors for a simple plug and play installation on your 2V 4.6L Mustang.Р”Р„ BBK Oil Separator Kit is a must-have for the 4.6L engine in your Mustang GT because during the process of venting crankcase pressure through your PCV valve into the intake, oil vapor can collect and coat the inside of your intake manifold. This oil separator kit can be installed in minutes without special tools. This ensures only clean, oil-free air is able to pass through into the intake. A high efficiency, multi-stage filter system is used to collect the very fine oil vapor droplets and deposit them into the easily removable bottom. The oil collection tank features a knurled base for easy removal to drain the captured oil and an O-ring seal to prevent leaks.
