Back to the bean counters again. If they can save 1/10,000th of a cent per bolt times millions of exhaust manifold bolts per year, the bean counter justifies his/her position.
Recalls don't save money. A five cents bolt may cost the manufactor hundreds of dollars for repairs, plus a customer in the future. Save me now, I'll pay later, attitude!!!! A bean counter can save a company money or close them down.
