were you leaking from the valve cover Dan?

I'm assuming at your miles you were probably due, also how bad of shape was your CCV in and your DISA valve? I pulled mine recently and replaced with a G.A.S. new silicone o-ring for 5 bucks, my DISA otherwise was tight and not loose when testing the vacuum actuator.

However, that DISA seal was flat as could be and I seem to have a smoother idle and slightly improved mileage/driveability since replacing.
