Crankcase Vents
The tubing for the front vents that go from each head to the center of the block needs to be replaced. I was wonder do I really even need those? It already has the tubes going from each head to the intake and the crankcase to the pcv valve. Do I really need the the second set on the front of the block or can i just cap them?

Re: Crankcase Vents
Subaru seems to think you need them. Non-turbo motors don't have them, so my theory is that they're needed to make sure vapors move freely enough between the heads and the block..

Re: Crankcase Vents
Yes, you need them. It helps equalize pressure between the heads and block. I'm pretty sure the STi motors have the center vent as well.
