A brief search (really, I don't want to spend more time on this right now) for "pcv which side" hits mostly on GM products, which I believe use the opposite side of Fords, but it always says that one side will have suction and the other pressure, and the pressure side is the PCV side. Why that happens I don't know - I'd think the engine would be rather symmetrical. But it is logical since if both sides had pressure (and thus large amounts of blow by) that there would be PCV on both sides.

In an OHV V8 the pressure would be equal on both sides because they're connected through the pushrod gaps and the lifter valley.
