1. Can it leak diesel into the engine oil
2. Does it get lubricated by the diesel ..- meaning the whole lot is filled with diesel and every part is reliant on diesel for lubrication.

anyone done a strip and repair of leaking seals

Yes to your first two questions.

Stripping the pump to repair will require it to be run on a calibration test bed to be "recalibrated".

OK - thanks knobby ... was only really thinking of removing pump and pulling the seal behind the pulley on this problem, so though its quite involved ..and possibly means me changing the timing chain cassette at the same time, whilst i'm there, because of its 142,000 miles. as i think it means disturbing the timing chain cover to remove the pump.

for the time being ill do an oil change, leave it short of the high level oil mark and observe how long it takes to to put this extra litre of diesel into the oil....knowing that its possibly evaporating some of it .

wish there was some way to work out if its the injectors or pump oil seal .

will do some reading up on this pump ..and get to know how it uses the diesel as a lubricant ..read it somewhere before, that's why i stated it ...

Are there one way valves in the injectors?

Diesel is essentially oil, so it is also used as a lubricant in all diesel fuel pumps.

Injectors don't have one way valves as such.....there is the best part of 25,000psi in them at full noise so it's unlikely fuel will dribble out of them under no pressure. TDDi injectors are very reliable.
