OK to run a catch can like this?

I got rid of the pcv and ran all 3 lines from the valve covers to a catch that i put in the compartmant under my battery in my ws6. Is this ok to run all 3 lines to the can? do i need to just use a vent on the driverside one?

You should be fine...just make sure that the fresh air line (the one from the passenger side valve cover to the throttle body) doesn't actually return to the throttle body (just make sure you put a vacuum cap over the nipple on the TB).

should i run line from the catchcan to the intake to draw a vacuum on the can? Or will it vent through the filter on the can properly?

Sorry to highjack your thread, but what is the proper way to run a catch can? From searching thru the site there has been 2 different ways.

I will be running a greddy 9mm unit. What is the proper way to install it? Pics would be great

Yes...run the line from the top of the can to the intake to draw a vacuum.

but its vented through a filter on top of the can, wont this defeat the purpose of having a vacuum? It will be just sucking air from the atmosphere and nothing from the motor.
