[Vwdiesel] Correct way to remove frost plugs?

[Shawn Wright]

Title says it - I think I have determined at least one *incorrect* way - drilling 
the centre and trying to pry out, which took a lot of fiddling and chiselling. 
I'm guessing drilling, then insert a threaded bolt & pulling somehow would 
work better? How about the little oil gallery plugs (about 12-14mm in size at 
each end) - or should I leave these for the shop to do?
I wanted to pull the big plugs just to have a look, and decided to drive out 
the int shaft bearings as well. 
I'll need to get a shop to press the bearings in, even if I don't have it tanked 
(probably will now). Not that it looks that bad inside, I just don't have any 
stray metal bits floating around.
