Myth, no, not rilly. Usually those leaks happen around the valve cover.
The I6 uses CCV or Continuous Crankcase Ventilation, not PCV or Positive
Crankcase Ventilation. The excess pressure is what was sending oil out
into your air filter. Now if both holes got plugged you start to see oil
and dirt build up around the dipstick.
Truly excessive crankcase pressures are usually caused by a bad valve guide
allowing exhaust gases into the valve cover. That can be enough to pop out
the dipstick or even the vent hoses.
You probably have a good amount of crud built up on the valve cover. If it's
leaking this would be a good time to take it off, clean it out, and reseal it.
If too much crud builds up in there it can break off and clog oil passages.
Generally, looking at the underside of your oil cap will give an indication of
how bad things are. If it has big clumps you should consider removing the valve
cover and cleaning it.
I'd probably step up oil changes to 3000 miles for the next couple times just
to clean out what may be trapped in there. No need to use engine cleaners right
yet as those tend to loosen the big chunks and cause more problems.

I checked the oil cap and it has a fair amount of "oily crud" on it, but not
sure if I see any "clumps". Then again, I have never taken the time to grab
some paint thinner and clean the oil cap, so I imagine its just 143K worth
of "crud buildup". I guess the only way to really find out is to take off
the valve cover and have a look-see for myself. Taking off the cover looks
relatively painless....any pitfalls I should be aware of? Also, how do I
re-seal it.....RTV and/or a gasket?

I had a change about 2500 mi. ago, so I will take your advice and change
every 3K for a bit.

Re: Clogged PCV tube
The clumps are the way the solvent breaks it away, kind of like if
you've every rattle can painted over regular oil paint, the surface
turns to alligator skin pulling apart.
