Thanks, the value of the car is only about $3000, despite it being a very nice ride. People can't believe it's 12 years old. I was thinking one of the aluminum powdered like Barr's that works with Blue coolant and isn't supposed to clog even though it doesn't stop big leaks. Mine leaks about a quart every 3-4000 miles. Something to soften rubber seals might be worth a try. I'm just not willing to spend another $2K on a $3K car. Thanks again for the response.
