The BMW engine damaging belt implosion issue occurs exponentially more frequently than you're describing, in fact is not uncommon. What is still unclear is what you may or may not know in respect to the damage to the ECS guard you installed as your experience is the only one I can find reference to / mention of. The crank balancer / pulley in these applications are also known to come apart / separate due to failure of the seal within. Marcel from Malo Ind. has spoken to (see above) your concerns re stainless bolt use in this application.
