that is not true.....only engine weve had that was prone to sludge if regular maint was not followed to the T was the 2.7.....
in any engine if you do not change the oil as recommended you are asking for trouble....

What you're seeing is oil vapors that rise in that tube, and are exposed to cooler air, causing condensation, hence the tan, gooie, build up you get.

Short trips where the engine doesn't reach full operating temps long enough to dry it out, will make it worse. Not to mention, the PCV valve is there, sucking engine/oil vapor up to that location.

Ford had the same issue on the older small block engines, at the oil fill cap, where the PCV fit into.

It's harmless.....just really annoying to see, and you'll see it more in the winter/coller months then you will in the summer, because of the warmer, summer ambient temps.

the best way to avoid sludge issues is to follow the mopar maintenance schedule to a tee using fluids with the correct recommended certifications.
following mopar's recommendations, we've had four late model mopars, all with over 100k on the odometer and not one issue...
amsoil is not a recommended lubricant by any manufacturer that i know of
