[Vwdiesel] Correct way to remove frost plugs?

[LBaird119 at aol.com]

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 always chiseled a slot into it then use a big screwdriver or angle ended 
pry bar to pry them out.  Once it's part way out, channel locks work 
great using the "heel" of them to lever it out. 
  It's a good idea to do the oil plugs but then they're dificult to find 
replacements for and get them to stay in properly too.  Dave Barbieri 
formerly of this list, had a shop installed one pop out and had to tear 
things down to find the problem, clean it up and reinstall and stake.
