Coolant Leaking Problems of Cadillac Eldorado

Vehicle began to lose coolant, but wasn't seeing any leaks. I then decided to open the coolant reservoir and smell for gasoline, and the odor of gasoline is present in the coolant. The vehicle was diagnosed and found to have a blown head gasket.

Starting with dic message of "low coolant", I have experienced an engine overheating problem. After the Cadillac dealer in durango colorado was unable to find a problem ( replaced hoses, water pump), my mechanic (in albuquerque)found a cracked head that was leaking coolant internaly. Fixed the head, but now the head bolt holes stripped. Used oversized helicoils , but block material still to soft and cannot torque down the head bolts without pulling helicoils. Aluminum metal got to soft and have to replace the engine. This engin only has 82k+ miles and should not be doing this. Aluminium for block/head materia is stupidity. Weight savings cannot be that much to have shorter life of an engine. L.
