427 FE S/O blowing oil out of one breather cap

Any thoughts about this?

Seems to happen above 3000 RPM. Fifteen minutes on the freeway and a few secondary road blasts caused a few ounces of oil, clearly under pressure, to blow out of the right breather cap and puddle at the base of the rocker cover.

Last time that happened to me, my I-4 Pinto Runabout (don't laugh) had a stuck valve which broke and damaged a piston.

But on this engine, it was happening only on the right side. Could it be some issue with the valve train on that side of the engine?

Engine seemed to be running on all cylinders, no smoke evident on acceleration or deceleration.

Is this one of those FE things? There was no PVC system installed, but as I understand it, that would only handle normal blow-by, not anything to this extent.

You guys know more, what do you think?
