My in-laws are visiting this weekend. My father-in-law is an excellent mechanic,
who gave me a great idea. Use a slide hammer to pull the plug straight
out, rather than attempting to pry it out. Less chance of damage that way.

Just when things were moving along, Ms. Rust and Mr. Corrosion came along
with their evil ways. I’ve got a pinhole leak in one of the freeze plugs
in the engine. When the water pump is off, there’s a small dribble of
coolant out the side. When the pump kicks on, tho, a stream shoots out
the engine a good 5 feet. Thankfully, the plug is right under the manifolds
at the top of the block..

This will be fun to remove. At least I can get to it, unlike the other ones.
Maybe a pry bar, or dremel’ing a hole through to use a screwdriver to
pry with.
