Agreed in stock form Its just the rear valve cover straight to the intake I'm convinced though all the plumbing slows down the rate of oil being sucked through the valve cover with the catch can. I still use a little bit of oil and by that I mean down to the next bubble on the dipstick in 4000 miles so I'm happy.
