Not Ranked
I was a GM manufacturing engineer for 15 years before Navistar. You can bet they know the risks.
Many times there is a balance between delivering something or delivering a good product.
In my opinion, Navistar made the right call. We only fixed pre-production type engines. They were run in test mules or on dynos and then scrapped. If there was a sealing failure, it did not hurt their reputation.
