Probably worth removing the head and having a look. Head gasket, valves, cracked piston would all be obvious with head off.

Finally got started.
When taking the inlet manifold off, I noticed that all inlets were full on dirty cruddy oil.
One of which was wetter than the others. No water though.
What would cause this please?

You mean the inlet tracts? Either valve guides/seals seriously shot or rings/pistons leaking and pressurising crankcase (does a crank breather route into the manifold?)
You might want to sort it quite soon as lots of oil into a diesel can be bad news.

The wet fresh oil is in cylinder number 2 inlet which is the one that wasn't firing.
There is a breather from the rocker cover that goes to the inlet manifold.

Have a look at valve guide seals etc. although it is possible the oil got there during removal.
Try pulling the tube off when it is back together and running, see if there is oil vapour pouring out of the tube.

I think it's terminal as far as I'm concerned the piston head has chips on the edge and the head has all carbonised.
What could have caused this, old age?
Head gasket just fell apart, so couldn't see any faults.

Hi sometime s the tip off the heater plug breaks off and gets stuck under the exhaust valve but this would evident on checking the tappet gaps one would be a bit bigger on no 2 cylinder could be a burnt valve . But if it's blowing oil out the breather it's pressuring the sump poss head gasket or if your unlucky melted or broke piston in no 2 . Did they say whether the injectors were bad if one was really bad I'd suspect piston has a hole in it .
