Heat kills Bl1. In the 35°C ambient race, the cylinder head expanded faster than the steel bolt, effectively "pre-stretching" the bolt beyond its elastic limit. 6. The "Laryngoscope" Theory (Novel Engineering Insight) The most interesting finding is that Bl1 functions as a mechanical laryngoscope for the timing chain. Driver Bolt Bl1
