This will be the location for a compilation of build dates that hav / have not had an engine failure. The purpose of this article is to give us some sort of timestamp as to when these engines / vehicles were actually built. Hopefully set some minds at ease as well to show how many true failures there have been. this is a small sampling from a video posted here: https://youtu.be/WmlzcwNtdjY
