I can not stress how important it is to change this filter and not at the recommended 60,000 miles but more Like 36,000. If you wait until the annunciator tells you to
perform service and you get a CEL with P1507 Crankcase Filter, while you're towing or continue to drive the truck, I guarantee you oil will be sucked into your turbo and then the fun will start in earnest.

Oil Soaked CCV filter
If you'll notice the tube with a hose at both ends by the Auto transmission dip stick in the above pic, that tube runs from the CCV filter to the Turbo and that's where the oil goes when the filter is saturated.
What you need:
CCV Filter: CV520010 CRANKCASE VENT FILTER ('07.5-'09) DODG1 $59.85 from Geno's Garage.
8mm or 5/16 Deep socket (Bolt on the back left is double threaded for a cable tie so a deep socket is needed.)
Step stool for a 4x4
How it's changed:
1.) Pop the hood and remove the 4 cap screws holding the front cover in place. Then remove the oil dip stick (Careful not to brush it up against anything) and then remove the front cover. Replace the dip stick.
2.) Now remove the 8 cap screws holding the CCV cover in place. (Remember that the back one on the left has a cable attached to it. To get that out of your way just pull up on the tie.
3.) Once the 8 cap screws are removed, clean around the oil filler cap, then remove it and lift the cover up and move it out of the way to the left. Reinstall the filler cap.
4.) Now lift up on the filter.
5.) Installation is just a reverse of the process. Remember to tighten the cap screws in a star pattern like you do a wheel and not too tight. There isn't a torque spec but when you remove them you'll notice that they aren't very tight.
That's it, and now you don't have to worry about mucking up your DPF and oxygen sensors.
