At 35,000 miles, intake gasket failure, coolant leaked into intake, repair covered by warranty. At 68,000 miles intake gasket failure along with head gasket failure, coolant leaked into crankcase contaminating oil. Was recommended by mechanic at the repair shop to replace engine and did. The new used engine had a intake gasket failure along with a head gasket failure 36,000 miles after installation. Informed by mechanic that a new gasket kit came out for this engine to fix the gasket failures with the 3. 4 liter. Both engines had the same problem. It is obvious to me that this is a engineering flaw by gm. I feel gm should cover the cost of this gasket failure.
