There are 18 of these associated with the two engines and their boiler feed pumps. Some are worse than others, particularly the pump glands which are letting water out and down into the crank cases. Whilst crankcase oil is designed to allow the water to separate out from the oil and be drained, I'm not sure it was designed to cope with gallons of water!
These photos are from April 2009 and show the state as found of the front engine pump glands.

|No better from this angle!|
Clearly there is work to do! I took apart the rear engine's upper pump gland and poked in the camera to see how it was.

I've been recommended greased hemp rather than graphite or PTFE for water pump applications. It needs to be 3/8" square section. Sentinel used to have an off-the-shelf item for this but it doesn't seem to be available any more for some strange reason...!
