Ihave a 1997 Pontiac Bonneville with 75000 miles. About 2 quarts of anti-freeze leaked thru the intake manifold and the car would not start. A local GM dealer pulled the engine apart and say the engine is ruined. What do you think. Can about 2 quarts of anti-freeze leaked thru the intake manifold into the engine ruin the engine?

The GM dealers shop says the anti-freeze damaged several internal parts and recommend replacing the engine. Manifold and head gaskets; other parts damaged.
