The PCV (Positive Crankcase Ventilation) system is designed to regulate and remove fumes from the engine crankcase, and to alleviate crankcase pressure which could cause oil leaks or seal damage. The PCV system routes crankcase fumes into the intake manifold where they can be burned to eliminate harmful emissions into the atmosphere. The PCV valve controls the amount of crankcase flow volume depending on the engine's load.  With large throttle openings (high engine loads), the more blow-by gases are produced, and the more the PCV system flows oil vapor in to the intake manifold.  A small amount of that ignited mixture leaks past the piston rings and ends up in the crakcase.  This leakage is often reffered to a "blow-by" or leakage past the pistons.  Some of the oil mist and other products settle along the engine intake and over time form a "gunk".  Our oil catch can collects the oil mist and condensed the fuel vapors while allowing "cleaner" gasses to pass back into the intake manifold.

Ultimate Function
Elite Engineering's PCV Oil Catch Can has a unique 3-chamber design to effectively separate oil from the crankcase vapors, thereby eliminating all negative effects of excessive intake system oil contamination.  Oil vapor from the crankcase enters the 1st - Inlet/Filtration chamber where it is slowed down and caught in the stainless steel mesh, it then moves onto the 2nd - Transition/Diffusion chamber.  The Diffusion chamber has a very specific set of holes to remove the oil and only let clean air vapor pass.  Lastly, the vapor passes into the 3rd - Exit Chamber before it exits the Catch Can.

Not all Catch Cans are created equally!  
Often imitated, never duplicated.  Most Catch Cans on the market are just comprised of an empty container with 2 ports.  While that simple design may trap a  few oil droplets, our Catch Can is designed to condense the oil vapor and trap the oil inside the container.

The Clean-side solution addresses that small amount of oil vapor that enters the intake air charge upstream of the throttle body during WOT operation when the intake manifold vacuum is not present.
The Clean-side solution allows 100% MAF metered air entry while trapping the oil during wide open throttle operation and allowing it to return back into the valve cover as soon as the throttle is lifted.
Simply installs as a direct replacement for your stock Oil Fill Cap allowing you to delete and replace the stock OEM hose.
At 1/2 the cost of the plastic hollow GM unit, our aluminum clean-side separator incorporates an internal coalescing material. Simply unscrew the top for a quick inspection or cleaning. Available in the most popular color Black, other GM colors are coming soon! This is a direct replacement for your stock Oil Fill Cap. Comes with vacuum caps and fittings if needed to connect to your intake air inlet tube.
