What are my catch can options for my 2004 Hemi?

I know it isn't as straight forward as other Hemis due to the design of the PCV system, but what are you guys doing to stop the crankcase ventilation from getting into the intake? A breather filter isn't an option.

Making custom bypass nipples out of the stock PCV Nipple plug or completly deleting it and creating your own vents.

Do a search using "catch can" and you will see a bunch of threads covering the subject. There was one thread that had a link to Modern Muscle I think that layed out the different systems that can be used/built. After fooling with several versions and not being impressed, I would recommend staying with the stock setup.

Why not just open air vent it with a breather like most of us have done? Unless you're running high boosted hp and need scavenging help like those using a header adapter set-up?

This is what I'm using now with the modified PCV becoming a vent along with fill tube.





With this being the most common that IMO works the best to just isolate the vent.

I run the external filter so blowby doesn't enter my intake thru the TB.
