Re: [T3] Distributor and breather box questions
<x-flowed>True for a stock engine but hi-perf engines don't always follow the
rules. What has constantly been told to me is that a bigger engine
produces more case pressure (due to blow-by? I dunno) and thus the
valve cover vents actually move air out and towards the breather.
Honestly, I haven't been given solid evidence either way so I'm not sure
myself. I would think that the case breather itself, vented to a carb,
would *seem* to be enough to reduce pressures in the case in a big
engine but I don't know how I would go about performing such tests. Tap
the case with a fitting and attach a pressure gauge? Then start
experimenting?

One problem with adding the vents to the heads is that most people don't
understand that the 72-73 vents were part of the PCV SYSTEM. They aren't
actually outlet vents but inlet vents...
