Oil in coilpacks

[Daggz68]

What could cause this
Taken the coil packs out and full of oil in them all.
Not had this cabrio that long
I've topped it up but not spilled any

I know it had an oil pump fitted before so don't know if that was any thing to do with it?
Or a clumsy ex owner

Rocker seal if plugs are dry & cleanish.

Plugs were full of oil too.
I've got the majority of the oil out and I've not lost oil. Hoping just some numpty has filled it by pouring the oil all over it.
I'll order new plugs and clean what else I can

On another not, on the rocker cover I've holes with threads but nothing to show what goes there. Maybe some. Bracket holding the coil packs?

Its normal when its getting old. You just need new valve cover gasket.
