Why do you doubt that this maybe the issue? |
I don't think it is the flexplate because a crack would have been noticeable at the time of installation, it's unlikely a crack formed in the short time the motor has been running without hammering on the car, and the noise from a crack would most likely be random and not in synch with rotation. If the flexplate was used there is the possibility of it being cracked, but I have disassemble more than 30 stock motors and have never seen a cracked flexplate. I have seen broken teeth and egged converter bolt holes. Just my opinion. If it was my motor I would take it out and inspect everything, the OP already has over 40 hours into this issue without finding a root cause.
