Cat open/closed crankcase ventilation need help with filter

Depending on the year of the engine cat made two versions of the CCV. The older engines will need to have the update done, which changes the canister to accept the new type filter. We have a few where the were plugging up every 6-8 weeks, and even cat couldn't figure it why there doing it. We simply snap the filter off and put the cap back on, haven't had a problem since. No more CEL for crank case pressure high.

 

Here are some pics of my updated occv filter





you will see the paint can lid to deflect any oil down the correct passage back to the sump,
the rest is simple just heat shrink,

you will not have the crank case pressure fault unless there are other mechanical issues, also you guys running deletes where the crank case pressure sensor no longer is seen by the ecm, you will not blow turbo seals and have oil leaks on the rest of the engine due to high crank case pressure ( blocked occv filter )

 

Do you need to make a hole on the bottom of the filter

 

If this is a retrofit to a mxs/bxs/nxs try:
308-9305 filter
5h-6734 o ring
322-2816 wear pad at bottom of the housing
