I have a 1994 Z28 5.7 liter 6 speed and I think I have a head gasket problem. I saw a product called Steel Seal online that repairs head gasket leaks by pouring this product into the radiator when engine is cold and then letting it run up to full temp. Have you heard of this product and if so what is your opinion on using this in place of going through a costly repair?
