ej20 swap to ej25

Does any one know how to plumb the extra crank case vent that the ej25 has? I'm using my wrx heads?

Thanks, T.

You'll need the ej25 plastic T piece...the one that comes off of the spud that is "easily" seen and not the one under the throttle body/intake manifold.

The one under the throttle body is the one I need to know how to plumb. The sti valve covers each have an extra port on them that connects to nipple under the t-body. So do I have to drill and tap in some unions on my wrx valve covers?

Either plug it up or plumb it with the breathers, personally I would plug it up.
