I suspect GM will need to do something more drastic than change its logo to return to profitability. They might start by seeking to recover the lost art of making head gaskets and intake manifold gaskets that don’t leak. My Mom just had to fork over $700 to fix a leaky gasket on the lemon they sold her. The mileage, you ask? 30,000!
All the evidence I can gather on this issue seems to indicate that the ancients actually found a solution to this problem, but the knowledge was lost during the ensuing decades. I recommend an archeological expedition to recover it. New generations of highly sensitive metal detectors could be used to find ancient dump sites. If an intact fossil of a Model T could be found, the key to the gasket riddle might be rediscovered via reverse engineering. GM would truly have taken a giant step back on the road to economic recovery.
