Not tell you what to do but it's obvious something is wrong internally. Why not make full use of your warranty and send the motor sealed up to Blueprint. Just thinking out loud that it probably won't change the outcome however someone has to pay the shop for the additional labor of digging into the motor and is that your responsibility. The flip side is I could see where you would be curious....
Sux all the way around but I am sure Blueprint will make everything right....
