Now Rudy, you apparently don't know that my car has 6000 miles and has the factory fill. (blue stuff) If I decide to put the car back to stock and take it to the dealer, I doubt they'll even admit I have a problem. To tell the truth, I'd rather fix it myself. I don't think the leak is severe since I've only had to add fluid (distilled water BTW) when I added a gallon capacity heat exchanger and separated the coolant system. None before or after. That's the reason I'm a bit perplexed by the goo. But goo doesn't lie. I guess I'm going shopping. Any ideas where to find one or leads will be appreciated.
