CCV valve replacement: Replacing CCV valve on Jeep Wrangler

[@stevenm.perronejr.1746]

Working on a buddy's '03 Wrangler TJ, and this was the only video I could find that actually had the CCV instead of the PCV! Awesome tutorial, helped me out a ton after I destroyed the front elbow trying to get it out. Accidentally broke the crankcase to intake manifold breather tube while trying the replace the rubber fitting on it too. That was a PITA to find for the '03 but thankfully Amazon has it all.

[@BrodieBr0]

I have owned 5 jeeps with the 4.0 inline 6. They are one of the best engines ever built. I love seeing videos like this since with proper maintenance these engines can live well past. 300K miles. Love you channel, Keep up the good work :)

[@JeepSolid]

+KIN Thanks! I enjoy making the videos and helping people out.

[@davehak2880]

I have a 2.5 yj and I love it. Get decent gas mileage.. What do you think about the 2.5 motor?

[@amyg.8592]

Thanks for the part numbers. Two auto part shops incorrectly gave me the back one instead of the front. And now I know that tonight instead of tomorrow night!

[@malcruzg]

Great content as we are sued to it but this was 6 years ago! I love when you specify the part numbers, that makes it so much easy to follow! Keep the great job!!

[@wolfhound802]

Cutting the gasket was a lifesaver, thank you man.

[@logowatchman]

As usual, a job that is simple on most cars is a pain on the Jeep. My 2001 Of the many cars I have owned over 60 years of driving, my 2001 Grand Cherokee is the absolute worst car to work on. You did a great job and I thank you for the help!

I was just looking at my 94 YJ and trying to decide the best way to pop those out, THANKS!!!!

[@woochin]

Just a tip: I was having trouble getting the valve into the grommet. I heated the elbow valve with a hairdryer to get it to fit!

[@iamcoachjuan]

Always reference back to your videos. thank you! this video shows the part numbers I needed also side note these do not fit on a plastic YJ Dorman cover I tried and broke a few times trying to make it work get the aluminum (2.5L on my YJ ) original hope this helps too. thanks again!

[@NDdelRosal]

Thank you for this video I was frustrated trying to remove the old part and all I needed was a new grommet! You saved me hours of frustration.

[@nicholasloomis467]

Thanks for the excellent video. Great tips. I just replaced the old leaky one on my '01 wrangle. The grommet and elbow were super brittle. Cheers!

[@orochikaiba]

Thank you for this. I'm about to change the oil on my mom's 2001 Jeep Cherokee and I'm positive the have never been changed, so it's nice to see a how-to done very nicely. I had my reservations about trying at first but now I'm just ready to get it done

[@JeepSolid]

Great! Glad it helped. Some are designed to turn 90 degrees and pop out. I'd try turning it first to see if it twists out.

[@orochikaiba]

@@JeepSolid thanks, I'll try that first. Maybe I'll hit pay dirt. But my mom has had her Jeep for like 10 years and I am positive this has never been done before so maybe not lol

[@silkytp789]

Great job on that. I destroyed mine taking it out - this was artfully done. Thanks.

[@JeepSolid]

+Silky Tp Yeah, It looks super easy, right? Just pull them out! haha. They can be a real pain like you said!

[@NathanKole]

Silky Tp artfully done is right. I wasnt having any noticable issues, but decided I was due for a change after 18 years. My old ccv valve is in approximately 47 pieces right now, but thankfully all squared away now

Good tip on grommet removal. Also, much thanks for part numbers!

[@JeepSolid]

+jaymes c You're welcome. Thx for watching.

[@theoboyles]

Thanks for the video! Just replaced my valves. My reason was actually because the hose going from the back valve to the manifold cracked, figured why I was in there, mind as well spend $25 and replace all the parts. I was getting some oil seepage onto the valve cover, so in the end it needed to be freshened up. For your viewers knowledge, I ordered the hose from my local auto store, got Dorman part #46006. This part actually doesn't fit the Wrangler, BUT, it'll work if all you need is the one hose leading to the manifold. It comes with two hoses taped together. The other hose (I believe for the MAP sensor) does not fit, I think it's intended for the Cherokee. I could have ordered the correct part from Chrysler, but I was looking at about twice the cost. 1995 Wrangler SE 4.0 liter I6.

[@JeepSolid]

Great Ian! Glad it worked out for ya and thanks for the tips on the parts!

[@faizullahsamir7945]

Thank you very much for the Great and clear Vids. I have a jeep Cherokee Poineer 4.0 1987. vacuum pressure is low(13-14), the RPM is unsteady and won't shift gear when going uphill. I have changed air control sensor, spark plugs, and fuel filter. I could not find a leak using brake cleaner. took it to two mechanic shops and they had no clue what they were talking about. thanks again.

[@augtenth]

Both of my CCV valves were seeping. I had done the front years ago but I believe the rear was original (2006 TJ) and was pretty bad. I had a high idle issue that went away after replacing the leaking CCVs. It had been up around 1100, now it's back down to 750.

[@Markus_4.0ooh]

Wish you brought up something about the bushings. thank you for the video

[@benromney9279]

I can't believe how efficiently you removed the old valves. This is some kind of witchcraft, I'm sure.

[@ninja63639]

I bought a '94 GC 4.0L for my CJ7 years ago. I ran it with no problems for a couple years. I had the Hesco mpi kit already when I did the motor swap. The frame started rotting out so I pulled the motor and a bunch of other stuff and got rid of it. I replaced it with my YJ. One of the first things I put on the YJ was the mpi kit and the 4.0 valve cover. I just pulled the 4.2 out of the YJ and swapped in the same 4.0 that was in the CJ. For the 1st time, I looked inside the valve cover when I went to replace the CCV and elbow. I was surprised to see that they were both CCV elbows with the orifice. As far as I know the motor was completely untouched when I bought it. It ran perfectly fine on the CJ and the YJ so I'm wondering if it was supposed to be like that? I put a regular elbow in the front like most all of them are but I've wondered about that since I saw it

[@JoeVizethum]

good video showing relevant tricks how to get the valves out - am not sure about where the CCV and PCV valve are located in my 1998 XJ 4.0 - front and rear - same engine you have - thanks.

[@prestoc3034]

They should be in the same spot (on top of the valve cover), but it is good to be sure of exactly what you have. Check out moparpartsgiant . com, and then select your vehicles info on the site, and then check out the part numbers and diagrams for the different parts of your vehicle, as to get an idea of what goes where. Some parts can be found/purchased on their website, but not everything is still being sold there, but with some searching elsewhere online, you will find the part you need.

[@JoeVizethum]

@@prestoc3034 thanks, dude - just checked: 53030495 is the rear valve which is discontinued, 53030991 the front valve which you can still order -- still not sure about the CCV/PCV difference and location front/rear.

[@prestoc3034]

@@JoeVizethum You are welcome. The front one that connects to the air cleaner box, is hollow, and the other one that connects to the intake plenum, is also hollow, but with one difference.. it has an orifice (a small 1/8 hole) to help stop oil splatter from getting up into the elbow. While the engine is running, air is vented and pulled from the completely hollow elbow (ccv), which draws from the air cleaner box, through the engine valve cover and out through the (pcv), which pulls the engine blow by into the intake plenum, via the vacuum pressure pulling the air through. For parts on your jeep that need replaced, try checking online at the "jeep hut", "rock auto", "summit racing", and if any of those fail at producing what you need, then you will have to check ebay and amazon, but be warned that they are not as professional to the auto parts info as the more 'dedicated to auto' stores will be. Those are the one's I have had luck with the most for my jeep parts. Summit racing is the fastest at getting things shipped out, but amazon is also speedy at shipping stuff out sometimes.. but they may ask a little more $$ for things.

[@thompytmmo]

Thanks for these tutorials; I’ve replaced nearly everything on an old family favorite. Having a tough time finding the location of the Canister Purge Valve on a 1995 YJ 4.0. It has stumped 3 good parts mechanics and my favorite mechanic, who looked for it with me under the hood, and then couldn’t locate it while on the lift doing a rear main seal job. Any help appreciated.

[@julieb9215]

Did you find it? I’m betting it’s underneath your driver side headlight. I have a 95 ZJ & that’s where mine is.

[@neekopeeko805]

Thanks for another awesome video! I have an '88 YJ with the original Mopar Fuel Injection conversion kit installed. It is possible deteriorated PCV and CCV connections can cause emissions failures? Trying to find the source of my high Nox. It's frustrating because half the engine parts are from the '88 carbureted motor while the top half is mostly from what I think is the '91-95 engine setups. But not sure, one commenter below mentioned his '93 used a "twist lip PCV." I guess we'll find out. I purchased it with the kit, so Im sort of figuring it out as I go.

[@wayneC7]

Why would you need to change these connectors? What issues were you having?

[@wayneC7]

What happens if these are not changed? Got a 2000TJ 152,000 miles and never replaced them in my 4.0L

[@Amarillobymorning777]

Eventually needs to change them Will leak air and oil . Remember. Be very very careful at removing them . Not debris in to the valve cover

[@ericdittler918]

What’s happening...I have a 2001 WJ grand Cherokee 4.0 I have replaced the ccv and PCs and grommets...where does the hose in the rear connect to off the valve cover?? I am stumped cause I just don’t see where it is supposed to go? Please help it would be appreciated...thank you

Great removal, one tip, don't use oil or petroleum products to help seat the elbows into the rubber grommets; direct petroleum applications on the plastic and rubber will break down both causing premature failure and brittleness. petroleum eats rubber and plastic. Use slimy spit after chugging a pepsi.

[@revolutionday1]

Uhhhhhmmmm......or just some silicone spray.

@@revolutionday1 lmao oh ya! You can use that too, but in my day I walked to school and work up hill both ways in 45 feet of blinding snow over 700 tons of broken glass with no shoes cuz they weren't invented yet and we had to... oops lost my train of thought... Yup silicone spray works too.

[@itandroid6304]

The back little orifice to intake is a pcv valve. The front to airbox is ccv.

[@ClintBoyer]

What about the part numbers for the hoses in case we break them? 94 YJ 4.0L here

[@phillipgrace8190]

So my rear PCV/CCV valve on my 2000 TJ is leaking oil all over my engine. My oil level is on par so it's not leaking too bad, and I put about 3 to 4 thousand miles on it a year. I have work I'm going to do in the Fall with my rad that has a patch job over a pinhose leak, and was hoping tob put this leak off too. Long story short. I was on a 300 mile road trip everything is fine, but all of a sudden my cruise control is out, just stopped working. Then it worked again, then stopped. Next thing I got the check engine light. So I pull over and look under the hood. It's dirty, but my only known issue is it revved high in park, and oil leaks from that valve. Not much I can do on a Sunday in the middle of nowhere so I push it 100 more miles. Fuel economy seemed to drop, other than that no problems. Good oil pressure, 210 degrees, RPMs not indicating an issue. In fact it sounded great. My bet is that valve trapped enough air in my engine to set off the check engine light. However, my question is do you know of any way that may correlate with my cruise control, or should I hastily be looking at my throttle? Or anything I'm not thinking about?

[@Jimmyyeehaw]

hey great video! doing mine now. quick question, should I be feeling any vacuum on the front elbow? I removed the hose but I don't feel any suction from the hose coming from the air filter or from out of the elbow. the back one has great vacuum coming from the intake.

[@trailwindz7833]

I broke the back house trying to remove it. Where to get a new hose?

[@Amarillobymorning777]

How did you fixed it??

[@nate4036]

What would happen if you deleted the pcv elbow and instead ran two ccv valves? Essentially both with big holes. I feel the 4.0 needs all the help it can get

[@SH0RTY625]

okay, I might seem stupid but I am new to the jeep world and I have come into possession of a 1992 jeep wrangler yj 4.0L and the rear ccv valve is missing the hose. So my question is when i get the hose where does it lead too? the front one goes to the air box but what about the back one? I also have a few missing vacuum hoses and was wondering if there is a diagram somewhere that shows where all of the possible vacuum hoses are and where they lead too?

[@tshomp]

Where does the rear CCV valve connect to? Ive never had it connected. My front valve is connected to the air box.

[@oliver4524]

The one closest to the firewall connects to a vacuum line to your intake manifold.

[@downtowndrewbrown7129]

I ordered the aft hard line and the dang grommet on it will not fit the nipple on the intake manifold. It's supposed to be a direct replacement from crown. Any suggestions on hose size for that particular nipple?

It holds up fairly well. It's designed for some oil contact.

Hello, just a question if you have a chance to answer. Will PCV and CCV elbows be the same for a 93 YJ 4.0? Because I looked up the part and it wasnt the same you have listed. Any info would be great thank you very much for your informative videos

[@jat-justamaturetech-philpj8285]

On the PCV elbow, is there a valve inside it or is it just a tube??

[@prestoc3034]

The first of the 2, (the ccv) is fully hollow, which connects to the hose from the air-cleaner box. The other one is the pcv, and that one connects to the intake plenum, and is hollow as well, but on the bottom side of it, where it goes into the valve cover, has an orifice (1/8 inch hole) to help stop any oil splatter from getting up into the elbow and through the vacuum tube.

[@jat-justamaturetech-philpj8285]

@@prestoc3034. On my 2000 jeep grand Cherokee Laredo 4.0 it's the opposite. My pcv goes to the air box and ccv goes to the intake. Just to be clear. The pcv is located on the top front of the valve cover and is the tall one?? The ccv is the short one almost flat and is the back one?

Hi Dale, well not quite finished in my book. If you don't check that the front and rear air lines are clear you have wasted your time and money. Having worked on several Jeeps where the rear manifold vacuum air pipe connector has been plugged with oil and carbon deposits. Thus stopping any vacuum being created under the rocker valve cover. It pays to be thorough and pay attention to detail.

If you're looking for the hose, they have it in bulk at any autoparts store. If you have a section to bring down, they can match it up. Then buy whatever length you're looking for. If you're missing the hose all together, I'd bring the PCV valve down and find a hose that fits well. It's just a breather hose, so doesn't have to be certain part #. Hope that helps.

For anyone else with a 93 YJ, I found out it has a different PCV valve than the one use in the video. To remove it, disconnect any hoses, then twist counterclockwise 90 degrees and it pops right out. The valves have different lock and twist lips and the ones in the video wont fit. heres the front valve on amazon: www.amazon.com/gp/product/B000C5I4ME/ref=ox_sc_act_title_1?smid=ATVPDKIKX0DER&psc=1 and back valve: www.amazon.com/gp/product/B01EIBOFIO/ref=ox_sc_act_title_1?smid=A108VDUN6CJBUD&psc=1 As a side note, under the front and back pcv valves there is a pretty big buildup of sludge/ carbon there. any advice on how to clean that gunk out before it damages the engine??

@@JeepSolid are you saying that I should just throw two pcv valves on each end just cause they fit? cause thats exactly what you said. I heard a pcv valve has different inner components and opposite function than the ccv?

I'm saying many places list them as pcv, because that is the common term. The ones I link in my video are the correct ones for my engine, and they are listed as pcv, but don't actually have a valve. They are just open elbows, with metered openings. Places just label them as pcv.
