Split the case if you can't see it. You'll probably waste a lot more time trying to get to it than you will tearing it down and reassembling it.

If you can see it, use a magnet. Good luck homey!

Reassembly, make sure you keep the correct lifters with the correct cam lobes etc. I would label the side of the case and the lifters with a sharpie. Replace the front and rear seals. Do an inspection of your bearings, and replace as necessary. Don't get in a hurry or be cheap; seal everything, clean everything, and inspect everything anal-retentively. Replace anything questionable. Better now than later.
