Sounds like the builder screwed up. How does the crank and the cap look? You need to look around for anything else in the pan. Say like a small freeze plug? The front bearing should not be the first to go as that is one of the first places the
oil goes.
I hate to say it but you may want to pull the enigne. Sorry man.
I would make a "nice" call to the builder and who ever told you to use them for engines. You may wish to apply a bit of pressure if you feel you are not getting any place by telling them about this web ring and all the folks you can let know about how customer freindly they are if you know what I mean.
