Yea ... definitely check the oil for metal shavings!
It would be a good idea to go back to that machine shop and see if they will do anything for you because a newly upgraded and rebuilt motor shouldn't fail that quickly.
I really don't think they will do anything for you though
They will probably say it was just you driving the motor too hard.
Hope everything works out for ya man.
