For what it's worth I am pulling 13" of vacuum on my 498" FE, I have a Dailey
Dry Sump with #16 lines to and from the tank. My valve covers are sealed
and the only vent is on the Stef's dry sump tank in the trunk. I have not really had any problems with this system and don't seem to have an
oil vapor problem in the trunk. We tried it on the dyno with vented vs unvented valve covers and there was a difference of about 20 HP. What I really like is the engine compartment stays really clean compared to the times I had remote valve cover breathers with baffles etc. The only time
oil gets out of this thing is when it is not running, then it leaks like an old Harley.
