In the past I think I used a slide hammer and drilled a hole, but I don't want the chips falling down the block and my motor is still in the car so the slide hammer will be difficult. Anyone have a favourite DIY method?

Easiest way to remove frost plugs

hi i can not help cause i do not know what are you talking about:o
I punched a hole in mine and stuck a large bolt in it and used a large socket with a fender washer and tightened the nut to pull it out. It's tough doing under the manifold. I think you can knock it askew and pull it out as Luis suggests. Don't worry, it can't fall into the block.

I hit them towards the side with a drift, to knock them out shape enough to lever out
The Freeze plugs are the circular metal pieces that keep the coolant in the block and pop out if the coolant freezes. There are quite a few on an M30 Block.

this is the right way
hit them a little latteral, not in the center, and they will rotate as luis says
I used "The Right Stuff".

They are often called freeze plugs, Welch plugs or core plugs. The holes in the block are a result of the sand casting core supports, and these holes are machined to accept the plug. Early engines used a threaded pipe plug, but then the Welch Brothers developed the common press-in version.
These plugs may or may not pop out when the coolant freezes.
if coolant freezes ... more likely water ... if it freezes, its usually in the radiator before the block. but i guess up in the permafrost area where NICAD lives - the block could freeze too. won't happen here in atlanta
