2003 chevy Malibu with 88k. During routine oil change was advised of oil in coolant. Upon taking to mechanic was told I had bad head/intake gasket and needed replaced , estimate cost $2400. Upon researching farther I found out that this is common on some gm vehicles with the same engine and that in fact a class action lawsuit had been settled in California earlier this year. In any case, I'm stuck with the bill on a repair that was caused by the coolant that the gm used and required as apart of the warranty.
