Valve cover breather

1690 Views 6 Replies 7 Participants Last post by  n0alpha
I was thinking about getting the same intake system that Rik got, and i was wondering if it would maybe be better to get a separate valve cover breather. If i get one does the vacuum connect in between the valve cover and the breather, or does it have something to do with the air intake?
Can someone explain to me what that vacuum does?

Thanks

Most valve cover breather systems simply use the intake (vacuum) to pull excessive gas/pressure from the engine. Some oil buildup/vapor is usually common, but in my opinion it is necessary because excess pressure will reduce seal/gasket life as well as many other things.
