Come along as I have a look at a customers 2005 Buick LeSabre that came in with a very small EVAP leak. This was an easy one as long as you know how the EVAP system on a GM works. They are perhaps one of the simplest in the industry.

    Eric, Thanks for your videos. They are enjoyable. Can you go to the chalk board and draw a typical vapour venting system complete with solenoid valve and purge valve. I am having a hard time to understand how the whole system is put together and how it operates. I would appreciate a Purge System 101 lesson. Thanks

    Hiya Eric

    I have a 2002 Buick Lesabre with the same issue. Replaced purge valve and didn't fix issue

  8. Avataaar/Circle Created with python_avatars Lionel Vasquez says:

    Great video. Very informative.
    You did one a while back where the GM fuel tank pressure sensor was the culprit. So this video was another one that helped me understand the EVAP system better. Thanks

    3.8 is a great engine, it's a shame that in the FWD application the rest of the gm drivetrain is garbage………

    Dorman products. For those technicians who love their job so much they get to do it twice.

    Awesome work Eric O.!! 👍👍

  12. Avataaar/Circle Created with python_avatars timothy hynes says:

    At least he had a 3800 , that was a great engine

  13. Avataaar/Circle Created with python_avatars CS says:

    I agree with Dans learning curve, nothing cheesy here! Your a great technician, and if I lived near your shop, you would be the only person that would touch my car!!! Thank you for the videos!

  14. Avataaar/Circle Created with python_avatars shay stern says:

    not cheesy, good job

  15. Avataaar/Circle Created with python_avatars Pat Jago says:

    I’m getting older but am happy to report that my purge valve isn’t leaking (yet)

    Good, do I don't know what it means. Do I have one of those, has never showed up…

    Yeah, at the outset I was like looks like summer, is this a current video? It sure is winter up in the Rockies man. any day now.

    Good engine, in Australia we had a razed aluminium intake manifold and RWD🇦🇺

    Hell I was getting my cheque book out to buy somethin' ,you sweet talker Mr O !

  24. Avataaar/Circle Created with python_avatars mohamed mutrif says:

    Hi Eric, I'm a big fan of you, could you please make a demonstration video on how the EVAP system works and how to diagnose it?

    Thanks in advance 🙂

  25. Avataaar/Circle Created with python_avatars LMacNeill says:

    I would love to buy myself an Autel — but the price is just a bit too steep for a DIY weekender like me. I wish the cheaper OBD-II tools had bi-directional control like that, so you can command things to turn on and off to help with diagnosing a problem. Unfortunately it's $1,200, $1,500, or even as much as $1,800 to get a tool that does that. Worth it for a full-time shop. Not worth it for the DIY'er.

    No effort diagnosis for No Effort November. 👌

  27. Avataaar/Circle Created with python_avatars zackary mcclain says:

    hp tuners can permanently fix these evap codes, Just sayin.

  28. Avataaar/Circle Created with python_avatars Peter says:

    Got a 2001 lesabre with a gas cap loose on the message center and a 440 code, tried a brand gm gas cap a brand new chant cap but still get the code and message.

    if you were going to chase an evap leak on your jeep 4.7 how would u go about that and where would u begin?

    Awesome

    "The only code in it" Pretty good car I'd say. 2005 ? Yeah, pretty good. I had a '94 Pontiac Sunbird, of all things…….had it for 200,000 miles with VERY few issues.

  33. Avataaar/Circle Created with python_avatars Ozzy Krahn says:

    i always learn from your videos

    I'm happy.

  35. Avataaar/Circle Created with python_avatars Xombi Xombi says:

    good bet, thank you.

  36. Avataaar/Circle Created with python_avatars Huntnfishnuts says:

    Toyota evap systems are just on another level of over engineered overcomplicated nonsense 😝

  37. Avataaar/Circle Created with python_avatars Yawwee Shalimar says:

    Since you only did a quarter of the work, did you charge the customer a quarter of the labor/diagnosis/removal/replacement cost ??? Inquiring readers/subscribers would like to know !!!!!! 🔍🔎❓❓❓👍

  38. Avataaar/Circle Created with python_avatars Michael Clarke says:

    When working on my cars, I’ve found myself muttering things under my breath such as “come on, baby!” when I’m struggling a bit and. “There’s your problem, lady” when I make a discovery. 😊

  39. Avataaar/Circle Created with python_avatars Guy Smiley says:

    I miss my old Bonneville with the 3800, that motor was such a gem. Sure it'd eat coil packs sometimes and the intake manifold gasket was perpetually leaking but the mechanicals of that engine were just incredibly rock solid. I wish I could buy a car with one in it today, honestly.

  40. Avataaar/Circle Created with python_avatars robert richardson says:

    But I don't want to forget about it… I want to buy the Autel scanner, or the Topdon with the oscilloscope if I can afford it. Lol Great video, we always need a refresher on some of the diagnostic processes you do!!

  41. Avataaar/Circle Created with python_avatars C V says:

    So you're telling me parts cannon? 🙂 3 shots max.

  42. Avataaar/Circle Created with python_avatars John h Palmer says:

    I got the money light on again on my 03 Mazder. Yes, the classic P5 with the 2.0L inline 4 pot. previous codes were the P0455, the classic P0090, the classic P0660. Now, I have no idea what, except that it could be the same things as I've not dragged out the old scan tool to see and then clear, it did that on the first go ust came back on a few days ago after clearing and it remaining off for about a month without any doing anything to it.

    Anywhoo, if it is those codes, suspect it may be the purge valve that has gotten intermittent. It only has, 195K+ miles on it and occasionally smokes upon startup, and clears up pretty quickly,. once moving after sitting for several days. Then again, it could be a liking fuel injector but who knows? car still runs fine otherwise.

  43. Avataaar/Circle Created with python_avatars paul oneill says:

    hi great work as usual, this may sound silly but what pointer are you using on your autel i cant seem to find one that works and my fat fingers are frustrating me 😁

  44. Avataaar/Circle Created with python_avatars Raving_107 says:

    What a coincidence, i did the same thing on an 02 earlier today.

    Does the autel have the ability to close the vent valve and control the purge valve at the same time? I can do that on our strapon scanner and its very useful for diagnosing evap problems.

  45. Avataaar/Circle Created with python_avatars R Winstanley says:

    You didn’t pay me for hitting it. You paid me because I knew where to hit it
