Even this crack doesn't need much attention; just weld it shut to ensure the crankshaft's sealing is intact.
After a simple repair, this crankshaft can continue operating in the engine for several hundred hours without major issues.
However, if Qin Miao had continued to race for more than five laps at that time, given the high-speed nature of the Baku circuit, the internal combustion engine's RPM would remain at around 12,000.
Under such extreme operating conditions, the crack on the crankshaft could potentially widen.
By then, cylinder scoring, cylinder explosion, engine blast—anything could happen.
So truthfully, Qin Miao's caution did help Mercedes avoid a significant loss.
Even though the technicians and assessment team felt that this engine could still be used following repairs, the team didn't dare use it in Qin Miao's official races and qualifying sessions.
