In this video I have a look at a ladies 2019 Kia Optima that came in with the engine light on and a code for a very small EVAP leak (P0456) A quick check with the smoke machine indicated that there was no leak. Or so I thought…
-Enjoy!

  1. I'm not a pro and I do have all the tools needed, but I find diagnosing the EVAP system a most frustrating and time consuming effort . And this issue always occurs just when either my family or I need to get an emissions inspection. Believe me I don't think I could mentally handle being exposed to numerous EVAP issues to a degree where I could say I have deep experience. Hats off to you!!! Thanks for a great tip on Subzero , appears to be much better than my homemade version.

  2. Any part used in an aircraft has to be tested and approved by the FAA. Aircraft splices have to meet several requirements for resistance to chemical attack and must maintain their integrity even at temperatures as low as -65 degrees. The aircraft splices work on the same principle as the ones Eric used. The difference is in the heat-shrinkable sleeve, which is made of a special thermoplastic epoxy.

    You could certainly use aircraft-grade spices in an automobile, but that could get expensive as they cost over $15 each.

  3. I have learned so much from this channel, I will soon be taking my exam for "Certified YouTube Mechanic" – thanks Eric. The utility of the smoke machine seems to really vary with the year , make, and model of the car I suspect. For example, it's proven invaluable to me for working on my 1982 Corvette which runs more on vacuum than gasoline! Use of vacuum hoses in that era is measured in yards not feet or inches! Thanks again for sharing so much with all of us. My best to you and of course Mrs. O.

  4. Diagnosis is on point as usual, so is the humor.

    15:07 I was thinking that soapy water is more like watery soap. Looked more like snot, but I didn't know products like these were actually made. I just always used soap and water, but that stuff does look more effective.

  5. Good to hear you back as your happy self Mr O. I was becoming concerned about the state of your mental health after watching a few of your more recent videos. Keep on smiling 😉
