Is it true that there is oil around where the glow plugs go?

Not that I recall... unless it is leaking in from the valve guides down and around the valve, and into the chamber.
The cylinders are lubricated from oil squirters aimed at the bottom of the pistons. If you are getting significant oil in the combustion chamber, then I would guess it either comes from the valve guides or from the intake. Another possibility could be it is seeping in from the head/block junction, but that would mean you wouldn't have any compression. I don't know enough about this kind of thing, sorry.
