See the hole inside the inner seal at the 5-6 oclock position, that lines up with the hole that goes through the webbing in the casting above, the water pump sits behind the power steering pump and is driven by the pump, so effectively faces the rear of the engine, it;s actually a good design, as it's only ever subjected to the same pressure on the bearings, unlike belt driven ones which can pull the bearing downwards, people don't change the OAT coolant enough though and the seals give up, water leaks on to the bearing and destroys them, and because you cant give the pump a wiggle to check the bearings, like you would say on a V8, a weep hole is there to tell you that the seal has gone.

Actually there are a few causes for the pump seal to go, oil cooler can corrode, agin by not changing the fluid, and allow oil into the coolant, swelling the seals.

The 15p doesn't suffer the same issues of oil going up the loom quite as much as the older 10p engine, that looks more like a, the oil pic looks more like a silicone seal gone, and the oil / diesel capillary's up the inside of the insulation until it terminates at the ECU red plug and eventually starts to fill the ECU with oil, not drip on to the engine itself.
