It's the tall, rectangular brass colored deal right under the plastic cover (if you still have yours on) kind of between the fuel filter bowl and the belt.
The Allen screw you want is a little to the right of center of it and faces straight up. It's only about a 1/2 inch in diameter, if that so you'll need a really small tube to stick down there to get it out. You should have about a 1/2 inch to one inch of space between the top of the oil and the hole.
Hope this helps -- kind of hard to describe without a pic...

Good point Joe......
No matter what oil I have run (I've used, Rotella 15W-40, Rotella 5W-40, Delo 400, Amsoil & Schaeffer's) my oil ussually darkens around 1K miles. I run the oilguard bypass as well. Whenever I dump it out of the pan, it is black. Observations on my truck and and 6 other PSD's (7.3 & 6.0) and 2 5.9L cummins I do the oil changes on myself. All of theses truck are either farm or construction vehicles. Oil analysis is the best way to see how things are holding up IMO.
