How to remove the crankcase filter?

Got a related post on this but trying to get a quick answer. I removed the two bolts holding the housing. I assume I just pry it out? Not sure how it sits in the crank case.

Also is the breather tube near the filter supposed to be rigid or should it be flexible. Seems like it is rigid as mine is but just checking to see if I need to replace it also.

Figured it out after seeing the new filter. Yep, it just pops out with a little prying/wiggling. It is simply sits in the casing with a large o-ring sealing it at the bottom.

The vent and return tube are somewhat flexible and fairly easy to remove with a flat edge screwdriver to slowly pry them off as you work it around the edge. Remove them before removing the filter.

Here is a pic of the crank case filter with breather and return tubes disconnected before I pryed it off if interested:

Why are you replacing it? Did your oil presure drop off or spike?

How does oil pressure tie into it?

Why I was replacing is dicussed in post here:
Spewing oil ... looks like oil pan front gasket leak, common?

Gotcha, that makes sense and the filter is a cheap and easy part to replace. Trying to recall what the maintenance interval is for them, but I can't remember.

I think someone mentioned it being like 60k miles but not sure. Not sure if this is a Dodge or a Cummins recommendation and/or if both agree or even list this. Doesnt seem like too many people are changing these at all but I certainly will be.
