It's actually true that a leaking engine will leak OUT more fuel also.
That happens when you get an air leak and you tune richer to compensate for the extra heat, that doesn't help of course and you richen it a bit more.
At idle you will now have an excessive amount of "extra fuel" and since idle gives the lowest possible vacuum the fuel will try to escape somewhere and that leaking bearing is the only way out.

There is not much arguments when running with a leak, EVERYTHING will be thrown off the charts. Nothing will add up and you will just scratch your head and become frustrated.
