New Corksport Oil Catch Can Question

[Scotty Boy]

Corksport just released a newly designed oil catch can. As part of the installation, they have you cap off the intake manifold port so it's not used anymore. Can someone who is way smarter than myself explain the reason for this and if there are any pros and cons? Link to instructions below.

I'm not sure. If I recall correctly, the catch can I had on my first gen went from the intake manifold to the PCV valve and left the top cam case breather alone. Maybe shoot them an email and ask if they can explain the reasoning to you.

In this setup they have it going from the PCV Valve and the Cam Case Breather into the catch can and then out to the Intake Vacuum Port and capping off the Intake Manifold Port. I'll contact them and post their explanation. Thx!

FYI, per Corksport:

"We noticed that by adding the PCV check valve to the oil catch can, the OCC worked less effectively because when the check valve closes (the car is under boost) the catch can is no longer able to do the same job of “catching” the vapors. When your car is under boost is the time the catch can should be working the hardest to prevent those contaminates from entering your engine. Instead it is just sitting there waiting for the PCV valve to open back up.

We decided to cap the intake manifold and pull vacuum through the intake so both cam and crank case vapors are trapped in the OCC leaving your motor the cleanest it can be. Now, the CorkSport Catch Can will be working to eliminate those vapors all of the time without the restriction of a PCV valve to prevent it from being able to remove contaminates while your car is under boost."
