1996 Pontiac Bonneville 3.8L Coolant in Oil
Posted to GM Engine on 4/6/2000

Hi group, Car has had a valve job done. When I was tearing it down found coolant on the top of lower intake. Wonder at that time if plastic intake might be cracked to let coolant into combustion chamber to cause the overheating problem and lost of coolant....
