Looks pretty light for 17.5 years of gunk and oil vapor...
Really, the only way to know you need to replace the PCV is to dig into it, or when a seal fails. Oil leaks are a big clue, but if your engine has only a bit of gunk like that, you're probably OK.
Dropping the oil pan, which takes an hour or two, will give you a look up into the oil separator (flame trap) and if you see carbon, you should do the whole thing.
Honestly, I wouldn't worry about it right now. 5,000 miles on Mobil 1 is pretty conservative. The big issue isn't the quality of oil, it's the additive package. If the oil maintains its acid-neutralizing properties, that keeps sludge from forming. Regular Mobil 1 isn't designed for extended drains, but should be plenty basic (anti-acidic) for a short run of 5,000 miles.
I'm a fan of the better European-specification oils. Two of the most stringent long-drain oil specifications are the Porsche A40 and MB 229.5. Look for an oil that meets either, or both, of those and you're good.
