2002-2007 3.7L Jeep PCV Valve! Loss of Power? Hard Start? Rough Idle? Oil loss? Oil on air filter? 

Thanks for the video sir. Mine was acting weird while running, losing power. This video goes straight to the bullseye. Now I can sell my truck with no worries. Total cost... 6 bucks.

Just when I start to question mine. Thanks. Will try out.

This video helped me to chabge the pcv on my 05 jeep liberty Thursday March 30th. I'm now about to do the spark plugs but I can already feel a difference in driving. The car.

2002 jeep liberty renegade bought new in 2003 off the showfloor. When wifey wrecked it, i lifted it with 2" moog deisel springs and a ARB winch bumper on the front with a pinch weld mod, and 265 16 tires (fits on original rim) DRIVES LIKE A QUAD I LOVE IT. You know, california would not let them in without a 1" drop ? they dropped it 1 " the front forks can raise the jeep 1 ". Also they would not let the deisels in the state. But it has 210,000 miles, looks great, (cosmetic damage only when it was totaled)

Good video. Reduced my piss/moan factor considerably. Whatever happened to simply pulling a PCV out of the valve cover and slopping a new one back in. Keyways, wiggles, seals and deals ... anyway, thanks for putting it up.

Nice walk through! I've been replacing all the small parts like this on mine for the pass month or so you know 30 bucks here and there and smaller parts too try too keep her fresh. 211333 miles on her and still running strong !

Yup I had the same on a jeep liberty sport 03 ,it would shake when I would press on the gas and oil pan light would come on and found out it was low on transmission fluid and the coil packs were what was making it shake and have loss of power

Im going to do this thank you and your daughter for sharing .

Dude. You are such a legend. I jusy bought a 2008 wrangler with close to 200k on it (i got a really good price) and had it inspected. Passed inspection but i still had all fluids flushed, filters check etc. I've had the rough idling at red lights and get that death shake sometimes, triggering the red lightning bolt and etc lights, also the blue/grey smoke. I told my mechanic to check the egr valve and he said it was clean. I'm 1000% checking and replacing this part tomorrow. I can't keep having that sinking feeling in my gut not knowing if shes going to start or if shes gonna die while im on the road. Thank you again. I will update.

Totally on point with what is happening to my 2006 Liberty THANKS 😊

i want to emphasize They were suppose to be 1" taller, but federal law made them lower them 1 " during that rolover scare. The front forks can slide up to raise 1" and the rear springs are available from moog.

Thank you, sir. I thought my cats were going out. Going to give this a shot and after looking at it today, oil is leaking out of the valve. Houston, we have found the problem

I will be doing this on my own as they want $125 to do this. If I can replace a number I can replace this lol.

I have a 2002, thank you so much! Perfect video. I will let you know if it helped mine. I am a subscriber. 👍

Hi I have a 2007 Liberty 3.7L V6, 117,000 miles. Owned it since 67,000 miles. It operated perfectly for the first 30,000 miles and then it started getting a #1 Cyl misfire code P0301. It also seldomly gets a #1 cyl fuel injector circuit open P0201. It must be a very mild fault as the misfire freeze frame data shows it always happens at less than 350 rpm and when cleared it comes back immediately at next startup, cold or hot. So it seems to only happen once on startup as its moving up to regular idle speed. The miss isnt noticeable when driving or idling. Its getting 15.5 mpg fuel mileage. Doesnt burn oil. Doesnt smoke. Has great power. I've changed plugs and coils but no difference. Cleaned air intake, air filter, and ran cleaner through system. I've cleaned and inspected the injector plug and all wires but no difference. Dry / wet compression test of #1, 3 and 5 cylinders all read good: 160 / 175 psi. I'm wondering if there's a mild wire defect for that injector, or just a flakey connection somewhere. Has anyone tried to use a new set of compatible gauge wires and run them to a place closer to the injector control? I can't see where the wires go though. I'm not sure if I should just live with this, or troubleshoot it more. I don’t care about the engine light as we don't have emission requirements. Now that I know the compression is good, I'm not so worried about it. Any suggestions of what to do next? Thanks!

Good job dad 👍

Wow im gonna change mine too very soon

That was a pressured line you banging on.

If you do one for the heater core, you’d be a legend!

Liked and subscribed, 2004 Renegade here, thanks!

Alright LETS TRY IT!

For the record there should be no click or snap... you have probably broke it if you did that... it slides into a groove and just needs to be pressed in all the way.

OK I just cleaned out my PCV valve with carb cleaner just as in video. Before cleaning I had a barely running idle, struggling and would almost die if I didn't hold the gas pedal down. What difference! Now I'm idling above 1 and exhaust output air has like doubled, its coming out like a hurricane. And lots of popping noises. What the world? I would never expected such a change in a million years from this little valve. What could have possibly caused this

Oil cap is loose to that will cause issues

Interesting

Thanks for the video My daughter has 2003 Liberty and loves it, now it start then shut right off Stay running long as foot is on gas, changed fuel pump relay but still does it Maybe this is the problem

Great video I have a 2004 Liberty limited V6 3.7L I’m gona change my PVC valve tomorrow and see what happens.mine is doing everything you said yours is doing.mine miss fires with no code.changed plugs still the same.Then throws the code P420 randomly.and also at times the thing will fly like peppy and then another you can feel it just hesitating.Did the pvc valve fix your issues?any advice or information anyone can share be great.

Just FYI … This does not work for the 2007 Liberty. The PCV valve is different, and is also in a different location. Good vid though! 👍🏼

I had a full bank misfire because my cats where clogged . I cleaned all the screen and dirt out and put it back together doesn’t misfire now although I have a weird rough idle . Being cold it won’t stay started but when it warms up it’s still a little rough any ideas ? Change injected o rings coils spark plugs

did the excessive oil consumption get fixed with the PVC valve swap?

can this trigger the abs light esp light and traction light on ?

you should of cleaned the port for better ventilation

Jeep V6 engine seem like they have a lot of problems to the 4.0 inline 6 was near bullet proof

nice but I just bought this vehicle and the hose on the PCV is not attached and I cant find it? runs fine but I feel the vacume is affecting my milage

What is the name of the hose connected to the pcv valve?

Usually, when I hear the "SNAP", the part is generally FUBAR

Mine kept fuckin up.did all kind of work. I unplug that valve now it's running great tf

I want to change my liberty 2003 engine

Did it work??

Um, did it fix anything in the end? 🤷‍♂

Disconnecting hoses?? Do only when hose is warm, not cold. Cold hoses can break due cold they wont spanand can break instead, Warm up engine if. Or use a hair dryer if cant start. Dont disconnect old cold hoses they will break instead..

Don't know whats happening, the birds are the loudest audio on this video .

YOU FORGOT TO TIGHTEN OIL FILL CAP
