What about the smoke machine?

[@billreinecke1949]

Thank you so much Oz. After going through 2 new gas caps, and tons of videos, I found yours and solved my JK evap problem.

[@kilderkarlakyler61821]

Did exactly the same and is leaking out of canister lines to the tank

[@chadgreen4853]

Great video! Thank you! Very informative… I thought that the process of finding my issue was going to be a nightmare, you just made it easy to understand. Thanks again

[@OzMechanics]

Thanks for stopping by Chad. Glad you liked the video

[@Irish4u2nv]

OZ your a awesome mechanic, thanks for your videos!! I just had my heads machined on my 05 GMC Sierra 1500 SLT Z71 because I had a couple of bolt heads broke on the driver side manifold. So did a complete head job because had to replace driver side head which are aluminum & had problem getting those broke cast iron bolts out, also one had already messed the threads up which led me to getting a new drivers side head & having both machined to even everything out. Anyway codes was cleared & drove home to find it still throwing this EVAP code. Luckily you posted this the next day, but my problem was a aftermarket Locking Gas Cap, but watching this I went ahead & ran your test & had exact problem as well!! Thanks for all your videos bud, wish you were a local mechanic here, but your videos are a tremendous help!! (👍#1 Life Subscriber)

[@robinsonsauto]

Great video Oz. The visual effects and explanations will surely help many people with this issue. Keep up the good work bud!!!

[@albertocortez2363]

parabens amigo, o video foi super util para mim. Muito obrigado por sua honestidade.

[@danpettis1675]

stupid evap systems. just because a tiny amount of vapor escapes it sets a code meanwhile the diesels out there are belching thick clouds of smoke .makes me laugh

[@eddylorenzo5033]

Facts

[@hermanrogers1325]

Well done you are a very good mechanic

[@hermanrogers1325]

Okay now I understand you have to do the smoke test at purge valve that goes to the gas tank and plug up the vent valve, my purge valve is in the fender well

[@mscottmiracle1396]

No smoke machine? Me neither. I did find my leaks with an old medical nebulizer/respiratory therapy pump that produces a few PSI. I hooked it up where Oz did, sealed the vent tube with needle nose vice grips and listened for the leak. I also sprayed some soapy water and looked for the bubbles. You may be able to find such a pump at a thrift store or E-bay,

[@ДаулетУскенбаев-ь4н]

Nice man. I from kazakhistan and i not good speak english. I have to this problems 0455. my car mazda 6gg and i cant find solution this problem.

[@jefferyeads4361]

Oz, thanks for all the tutorial info. I have a 2005 Chrysler Pacifica and it is giving po455 code. On inspection at the tank after replacement of gas cap, I found the gross leak possible coming from fuel filler tube to inlet tank tube. I have looked for a video to show how to replace the fuel filler tube on this vehicle. But with no success in doing so. Do you have a video on how this is done or can you point me in the direction of a video that shows what I am after on the 2005 Pacifica? Thanks again for information ahead of time.

[@HomieHektor]

I just had the exact same issue on a Dodge Caliber🙌🏼You got so much smoke going there you got me blowing at my phone screen 😆

[@jonathanEricStaffordRealtor]

Just replaced the white part and the o ring how long to wait for the code to go away ?

[@jamesjohnson427]

If you don’t have safety test laws in your state evap leaks don’t effect performance of the vehicle, so ignore your check light that’s caused by evap leak!

[@essamtal4333]

Very helpful video Thanks

[@flatratemaster]

Nice Oz, as high failure as the valve it is good idea to replace it at the same time!

[@hikerJohn]

What is smoke made of? It seems it might contaminate the fuel tank if any of it condenses out(?)

[@OzMechanics]

Mirella oil sometimes is used. And it doesn’t. These have been used for yrs.

[@ronaldlehmann6935]

Good teacher-u make it easy to understand-thank-u

[@realjaxon]

Would a restriction cause a whoosh of gas vapor to come out from the fill neck when removing the gas cap ? That was happening on my '02 DOHC Taurus several times until it stopped on it's own. But I now have a gas smell whenever I drive the car, and I traced it to the rear of the car with an electronic gas sniffer. I don't know exactly where it's coming from yet though. Any ideas what could be going on ?

[@essamtal4333]

What about Chevey Lacetti 2007 could you pls give me a idea thanks

[@krystaljohnson8258]

Yooooo i changed mine today and my P0456 code disappeared immediately 😊Thanks so much for this. Such an easy fix!

[@charlesrath8393]

You did not show how to undo the electrical plug. I wish you did. Wonderful video otherwise.

[@OzMechanics]

Out of this whole video which shows how to diagnose and fix the problem, you put something negative and say it’s all bad because it didn’t show how to remove the plug

[@charlesrath8393]

Very nice video. I wish that it was shown …because it was unplugged 👍🏼

[@mihaiprigoci5670]

But OBDII P0442 code what means? I have a KIA RONDO 2012 yr, 4 cyl. The check engine is on after error code erased. I changed the gas cap w/new one KIA. Very expensive in Canada. I can't fix the problem yet. Now I'm looking for a canister purje valve to be changed but I'm not sure yet. In EVAP system to fix the problem must waist a lot of $$$$.

[@peterzinia3767]

So why did you replace the part if it was only the O-ring that was causing the leak? That isn't cool.

[@josenilo1784]

[@terrellblue357]

I have a 2014 Buick LaCrosse 3.6L and have two codes (P0445, P0442), which caused me to fail my emissions tests in November of last year. Ugh! I installed a vent valve solenoid in the charcoal canister and couldn't make it flush to twist into the canister because of the catalytic converter pipe being in the way, preventing the tank from coming further down. So I think I'll go to a shop here in Chicago that will let you rent a bay and I'll be able to access it better because it'll be on a lift. I really appreciate these videos because they're so helpful and informative. After seeing your video, perhaps the O-ring is part of the issue as well because I've replaced the gas cap already.
