From what I gather this is a head gasket or freeze plug. No loud noises from the valves and it runs good. It did overheat 2 times but not for long. I guess i should look behind timing cover to see where it's coming from? Hate to scrap the car. Head swap doesn't look to bad or pricey. Car only has 100k miles. This site has kept the AC blowing cold and enabled me to change my timing belt!!! Receive thanks in advance for your advice!! I think I have researched this about 4 hours I could probably taken it apart by now!! Should of made a poll Scrap or Fix? 97 escort wagon.
