My sons 96 Century 3.1 looks like it may have a blown head gasket. That’s what 2 mechanics have advised as it did overheat and although it shown no performance issues, I do see some bubbling in the overflow tank and the temperature gauge goes up and down while driving. I’m having a hard time believing it’s a head gasket as there is no water in the oil and nothing coming out of the exhaust. Any way, I hear that an application of “waterglass” or K&B block seal will prolong its life. Anyone use these products with any success?
