    New ( to me ) '13 Cascadia with DD15. Leaking at the bottom of filter. Can the filter be replaced? How? What else would cause a leak there . Engine uses no oil, and runs fine.

    Yes the crankcase breather can start leaking, it's a centrifugal filter and if it locks up oil will just leak out the bottom. The entire assembly is replaced as one piece. 4 bolts and the line to the block. (Some have the speed sensor on them also, which is actually just a camshaft position sensor).

    About the only times I see leaks there are if it needs a crankcase filter, or excessive blowby caused by a cylinder kit failure. But usually if it's the latter it is a terrible leak, and you'll definitely already have coolant in the oil.

    And whole assembly needs to be replaced? Good idea...if you're Freightliner. Not so much if you're the owner
