Yes, it's reasonable to believe the 'problem' (to the extent there ever was one) has remedied itself.
My 987 would occasionally show oil down a bars, or two or three. I never knew quite why. Hot? Cold? Slightly non-level surface?
I soon learned not to react quickly; invariably, it would return to the top bar. Wonderful motor - never burned or used an oil at all.
How I wish the car were still here so that I could fuss over it. There's a lesson there, boys and girls. Love the car and don't agonize over the small stuff. Pay attention to it, for sure, but don't let it spoil your day, nor the enjoyment of such a superb car.
