It's better for the environment.

Just run the front breather and PCV hoses to a breather can. Also, cap off the port on the IM for the PCV hose and gut the PCV. Much better for relieving crankcase pressure. I used to run sealed catch cans and krankvents, but since I upped the boost, my dipstick always popped out. Now, I have no issues when using a breather can.

 

Run lines from both the front breather and from the fitting where the PCV was previously located to the catch can. If you simply put a filter on the front breather, it will quickly become saturated with oil (pressurized air will follow the path of least resistance).

 

thanks for all the input!
