Anybody got anything on an oil leak from the MRGB, somewhere in the vicinity of the oil cooler, oil cooler fan, oil cooler fan drive shaft?
A very small volume of oil is getting blown out through the cooler fan exhaust duct (hence the focus on the fan and related bits) leaving a fine spray of oil out over the top cowling, spine cover and all the way back to the vertical stabiliser. Fan drive shaft seals already changed - twice!
