Oil Leak from the dipstick

[Rtaylor2208]

I noticed last night after having the cab parked up on a banking that oil was leaking out of where the dipstick goes.

Is this just a failing o-ring or anything more sinister?

Check the oring on the dip stick.

Thought it might be, it was too dark to start trying to figure it out last night, dont suppose you know if the o-4ring is an off the shelf size or dealer part only?

Im sure you'll get one a B&Q, just walk in with the dipstick in ya pocket.
