The spec is around 0.2 mm, It will go alot more than that before it cause problems, it will start to wear the timing chain cover when it gets excessive.
The bad news is that it may be the crank wearing and not the bearing surface. There was a bad batch of cranks in late EF and Early EL's that wore out in as little as 5000k's.

i had to replace the crank in my brothers el due to that problem, inspect the thrust surface on the crank, its very obvious when theyre flogged out
