Hello, I've got a freeze plug on my girlfriends 2000 Dodge Neon that has been seeping a little antifreeze out. It loses about a quart of antifreeze every 3000 miles.

It's pretty tough to get to in a neon. I'd probably have to take off the exhaust manifold & the passenger side CV axle. I was able to get my hand up in there and push on it. It feels solid, didn't push out, but still leaks.

The car just passed 100,000 miles and sometimes knocks just a little on a cold morning start.

What would you do?

Just add antifreeze every oil change until the engine wears out and needs rebuilt, or fix the freeze plug now, or other?

Can it be fixed without pulling the engine?
