Pcv valve

[ShadowsPapa]

If I had a dollar for every catch can post. Man, I’d have a few dollars.

Gonna have to remember to add it to the jeepgladiatorforum.com bingo card.

And if I had a dollar for every Pentastar in a Wrangler or Gladiator operating fine without one, oh, heck, include the Grand Cherokee for kicks, I'd be paying my hospital bills with cash and throwing a huge party with what's left - all forum members invited.

I’ve got what looks like a leak coming from where that #3 hose connects to the intake. Is there an o-ring there that I could replace? Hard to tell from that parts diagram.

Pretty sure you have to buy a new hose to get the o-rings. Only separate o-ring replacement I have ever found for the PCV system is for the PCV valve itself.

or bring it here and I'll go through my assortment of o-rings I've collected over the years from transmission kits and so on.
One thing that could be tried is to remove the fitting, clean everything thoroughly and insert it back in place with a bit of the MOPAR RTV on the o-ring and let it sit several hours to cure.
Looks like a very slight seepage over time. Takes only a part of a drop of oil to cover an area several times that large.

The ones I have seen remind me of AC line o-rings. Sure there is a common size out there, just trying to figure out which one it is.

That's a new product - an ooh-oh ring.

It's the one I took off of my 21 when I installed the catch can.

Your PCV system in a smog device and directs any blow by and gasses that are normal in your crank case to the intake to be burned instead of allowing then to enter the atmosphere.
This is a good thing for the atmosphere but can contaminate you intake and combustion chamber.
A catch can is simply a filter that separate the dirty oil from the air entering you intake stream keeping your engine cleaner and improving the octane levels.

THIS!

It's nothing more than a small scale distillery. It postpones the flow of hot vapors from the crankcase, containing atomized oil and water, just enough to cool them and make them condense back into liquids. The collected liquids are saved in the container, and the cleaner "air", for lack of a better term, continues on into the intake.

The similarities in taste between the collected fluids and Jack Daniels are purely coincidental.

Hard to pick a favorite ?

Looks like there’s some damage or something to that inner seal/lip?

The idea of the most simple/cheap type is to provide a large chamber where the velocity of the air is slowed to the point it can no longer hold the oil or other vapors, and it "condenses" in the cooler, slower air movement area.
And the best also have a filter - it's a whole lot like the system AMC used - with some small success - in that the air went into a chamber in the bottom of the intake manifold where there was a brillo type of mesh that was supposed to catch the oil and let it connect and drop back down into the valley.
Trust me - leave off that baffle or leave that mesh out from the bottom of the intake manifold on those and you'll be sorry.

Bigtime.

Nope.
You may be seeing the offset on the locking mechanism.
