200TDI Oil Galley plugs

howdy all,

Im removing the two oil gallery plugs situated behind the timing cover
(jet washing block this weekend, attached image shows plugs still in place)

They were dot punched into place - question, do I need to put threadlock on them when reinstalling to prevent oil leaking up the threads?

Or do they go back dry and then re-punched?

Loctite and centre punch has to be the way to go.
