anyone know where i can buy a ccv filter?

Filter?  You mean the small K&N that people use to bypass it?

if your answer to jeffy's question above is yes then search ebay for "breather filter" or valve cover breather - you'll find quite a few ranged from $3 to about $20. But keep in mind that you might get blowby gas in the cabin

I use one on mine with no problems but YMMV.

What works well is to use a breather filter of an old chrysler v8 and then run a hose from that to the airfilter box. I used to use that on chevy engines that fouled the airfilters with oil, worked very well

[jeepyj95]

its the one at the back of the engine on top.

yes, the one that goes to the air filter box with a plastic elbow, not the one with the brass fitting that goes to the intake manifold (that you need to leave it as is, make sure it's not obstructed, clean it with a rod if it is).

So you're basically making a oil catch can/air/oil separator?

[jeepyj95]

would it be okay to put a breather air filter on it rather that running that hose it is connected to back to the air intake?

[aw12345]

Yup but it still connects to the air filter, the oil vapors seem to turn to oil and drain back into the valve cover

Yeah, the oil particle vapors are larger and get stuck on the filter then collect there.  The catch can works by giving the vapors a large enough cavity that the vapors cool and the oil condenses.

The only problem with having just a filter and venting out into the engine compartment is that that oil will not condense on your valve cover.

you can also get a large oil catch can off ebay for about $20 or even less but you need to mod it and put some sort of filter inside for best results (they come empty), will work better than the breather filter and you can still go to the stock airbox from the outlet of the catch can.

well in that case i'll just run the hose back into the air box. i'm gonna make a custom intake a t some point: can i rig it to fit with that assembly?

As long as you make it with a bung for the hose, it will work.  I'd consider replacing the hose with silicone hose since the plastic can crack if you're moving it around a lot.

It does the exact same thing as a catch can, but it still keeps the smog system legal does not foul the airfilter and used to cost about 7 bucks has no filter in it just course steelwool. It's what I would use on a YJ. Also you can also run the vent hose into the the tube that goes from the filter box to the intake that way it happily slobbers the fumes but doesn't foul up the airfilter. That is basically what Chrysler did with the 2.4l engine
