My oil burning pig. Pics too!

Thanks for the answer on the intake, despite all the frustrations. Sealing better is a good step.

The one thing about the evacs vs PCV to know: The intake manifold and intake runner pressure is waay below the evac pressure under the valve cover any time you are below full throttle, so any seal or guide leakage will still occur. A PCV will do a better job of equalizing the pressure between intake runners and under the valve covers, so will do a better job of lowering any leakage. So it is not solid thinking that the evac will do as good a job. If you spend a lot of time at cruising and other non-WOT conditions, where the PCV is active, the PCV will doubtless do a better job.....(edit to add:) largely because it equalizes the pressure above and below the seal and guide.

But, the evac should be better than no crankcase venting system. And the PCV is not active all the time, like at WOT, which is where the evac will still be working. Evac's are quite appropriate for racing conditions where the engine is at WOT conditions a lot.

Not trying to preach at anyone, just explaining the difference. Sounds like examining the rest is a good next step in your case. I sincerely hope this gets all cured and you have a good report next time.
