Since first oil change, car has always been filled with Mobil-1 10W-30 full synthetic; and regular oil changes.
There are no signs of PCV trouble and/or crankcase overpressure including weeping oil out of filler cap area or pushed up dipstick; but, then again that's high mileage for PCV that's never been serviced.
Options as I see it:
1) Keep a close eye out for PCV symptoms, or
2) Change out the PCV with new parts? (and at least a day's work!)
btw, five speed AW-55 gearbox fluid changed out every 70K or so with Mobil 3309, still shifting and running well.
Thanks,
