You'll be fine, I wouldn't worry about it at all.

 

I wouldn't risk it but that is just me

 

If you didn't flush it you might have a chance of getting it out by removing the valve cover, but since you flushed it with another 10 qts. of oil, I'd say it's down in the pan by now. I would agree with others that say it's just gonna chew up and melt during normal operation. In addition it should be caught by the oil filter, since that's what they are for.
Good luck.

 

just go get a flux capacitor from pepboys and you could pour in the bottle as well and not worry about a thing. just make sure you have enough road...
