Maintenance free Crankcase filter

So I replace the breather filter and it goes away. Filter is always plugged with oil. Would this filter your talking about for the isx happen to fit? Thanks for your help.

I'm not familiar with the ISC, but if it does not use the same c/c filter as the ISX, then just drill a 1/2" hole in the plastic part of the filter NOT the filter housing near the top atmosphere/exit side of the filter.
If you're getting that much oil in the filter this may be a better way to go anyway as it increases ventilation, but will trap most of the oil instead of ventilating excessive oil vapor making an mess on the underside of the truck.
