DeeGee, assomeone else mentioned this in the other thread, but it definitely looks like the rubber hose is pulling away from the valve on the oil tank there.
It could be sucking air or all sorts of shite into the oil line. You should be able to just pull that rubber hose off, ditch the metal clip, clean it up and secure it with a jubilee clip.
You won't lose any oil because there's a valve in the fitting the hose is attached to.
