It would appear the faulty number 2 injector seal had been melting the rubber seal and cam cover from the inside ,what they thought was diesel seepage was oil mixed with some diesel .

yep thats what they do that is what i was telling you about before when G-A-R-Y; rudely pointed out or implied that anyone on a forum should not be believed and should be treated as such,,, he's right you dont know who is giving their 10 pence worth and how accurate it is as if you had just replaced the seal you would be looking at a new engine or turbo or both within 10k if had not done a full check and repair to it,
hopefully the garage can recut a seat in to cylinder head to seal the injector, could try some well seal on the seat and copper seal dont normally use it as they should seal without it,, also could increase the torque setting to the fixing on injector by 20% and use lock tight on threads hopefully will prevent it coming loose again,,
the early 1.6 psa diesels on the mini would do same trick and on early one did it a lot and the carbon it caused would block the gauze filter on the turbo oil feed pipe and cause turbo failure and then this would cause diesel runaway a lot, clean oil on a turbo car is so much more important

What are the chances of the injector seat being ok ?
Or should the seat cutter always be used after a chuffing injector seal .
Thanks

depends on the seat and shape of first injector seal gives a clue, also i use a endoscope type camera and poke down in the hole to view the seat. i would never just cut a seat for the sake of doing it as the seats only ever get damaged from loose injectors. or on some cars that water has go in to the engine bay and on top of the engine ie almost renault dci engines will corrode and injectors end up codded in this can cause a lot of damage,, i have a habit these days of very thin wipe of high temp grease on the injector shafts just helps the next time they might need removing,, guess one of my pet hate how car makers dont use lubricates on stuff for future strip downs almost like they want it to be a bigger job than it needs to be,

Thanks.
The engine is now back together and all seems well .
The other problem however is still there.
The stop start is not working .
The fault was recorded as the brake servo pressure valve .
A new BMW/Mini part has been fitted and the fault code cleared .
After a 40 mile drive today the stop start did not operate .
There are no faults showing after another scan.
Originally the stop start symbol would come on the dash with an explanation mark when you stoped .
This would then go out and a warning triangle would stay on untill the engine was switched off.
Any ideas.

how old is the battery. how was battery unplugged while working on car might need recode back to ecu or ecu has picked up the battery getting weak, or battery is tad low while been off road, ie recharge over night see if car plays nice again, at least re code battery to car to rule it out very common with battery unplugged for system to need it, would do that before putting battery on it.
also would question what diagnostics platform used to scan it as some will not pick up some codes,
