On other kinds of engines- specifically, those that are not wet-liner, and
have the piston bores cast right into the block, these plugs are called
"core plugs"- they are used to remove the cores of casting sand from
the block after it is cast.
However, I guess they're really freeze plugs on our wet-liner engines.
You could use RTV sealant if you like. Some people use nothing at all.
Haynes recommends the Proper Sized Socket as a punch to install freeze /
core plugs; just a hammer might damage them.
