    Hi Matt once again great video. I have had numerous issues with my Z28 Camaro and you have helped me understand a number of these problems. Just like that Smog pump issue. I too had the slow fill problem but mine was just a kink in the main filler hose. I had to put a hose clamp around the kink to make the pipe round again All good now. I also noticed that EVAC vent Solinoid, I think is the same solinoid used for the vacuum relief solinoid on my smog pump outlet pipe

    For years I used jack stands and a creeper in my little one man dog and pony show garage. I finally bought a Challenger 10K pound asymmetric twin post lift after which I ceremoniously threw my creeper in the dumpster. Watching you work on that land yacht on the floor makes my heart hurt for you. That being said, kudos to you for making such great videos with that level of adversity. I freely admit I am spoiled and I will never work on another vehicle without it being on a lift. Once I set the lift I’m done with all the work I will do on the floor.

      about 6 months ago or so I did buy a quickjack 3000TL midrise and while not nearly like yours, it’s a massive massive improvement over jackstands. I just can’t put a 5000lb SUV on it. I do plan to also get a 7000TL which would allow me to lift these bigger trucks and SUV’s. 3-1/2 feet is still such a massive different over jackstands I think I can live with that!!

    Years ago I bought a similar smoke machine off ebay for about the same price. It works fine, but I wanted a flow meter to quantify the leak. So I bought a simple floating ball flow meter for about ten bucks to add in line. Expensive smoke machines come with pressure meters but I don't have much use for that, and the extra cost is significant. Smoke machines stink, the garage doesn't smell the same for a few days after using it. This was a nice practical demo. I've always thought evap problems were simple, but some of the new systems have a whole lot of extra lines and check balls/vents that can confuse the issue when you apply external pressure. Eric O makes these sound very simple, but I've been humbled.

    • @SchrodingersBox
      @SchrodingersBox  Год назад

      Good to see you back regularly Dave, reminds of the old days haha. Yeah the system I described is a GM system and for the most part the little ball flow meter would be helpful but I have found other systems can be vastly different. some have pumps to test the system for leaks. others actually calculate the volume of fuel in the tank and the outside temp to calculate what must be the pressure of the vapor in the tank given those conditions. they can any number of one-way valves and complications quite different than this simple system.

    If you fill up the tank too far(keep going after the auto shut off) you can saturate the canister with liquid......only vapors should go in the canister.I worked at a gas station in my teens in the 70's before I knew this.

      @@brianw8963 Yea the systems were primitive back then,but this was when gas was .50 cents/gallon,so if the pump stopped on$ 9.05 I would round it up to $10.00,almost 2 gallons.
      There were times I felt like bouncing the car to cram that last few cents in lolololol.
      This was when a lot of cars had the filler cap behind the license plate so if I spilled over a little the customer never knew it.
      I found a website called TitleMax and they have a list of gas prices going back to the 30's,and I was suprised to see that adjusted for inflation prices have been at $3.00 or above for most of that time.
      I started pumping gas on my 16th b-day in 1973 right at the start of the oil crises when prices went from .40 to .60 in a short time.People were shouting at me like I was responsible,and they watched the pumps like a hawk to make sure they got what they paid for.
      This was way before self-service was even a dream,and I discovered a way to get back at the nasty customers by "hanging" the pump on them.If I had a previous sale for only 1 or 2 bucks I could hang the nozzle back on the pump,but not totally shut the reset lever off.
      So the next car there would be a dollar or 2 before I started pumping.It took a delicate touch but I did it occasionally and never got caught.

    @evontrizmo Год назад +1

    This thinking with no box stuff is quite refreshing and something you just don't find on other channels. Definitely an effective approach to diagnostics for sure!
    There's also no doubt the canister is blocked with the back pressure, smoke blowing out around the inlet port and no air coming from the outlet port, but would the charcoal inside adsorb the smoke itself like it does hydrocarbon vapors and just pass clean air through? Is the smoke a hydrocarbon? Just curious on what to expect if the canister was not blocked.

    • @SchrodingersBox
      @SchrodingersBox  Год назад +2

      Good question. while the charcoal may adsorb some (certainly not at that volume) in my experience it flows through like what you saw with the vent. also- even if the smoke was all absorbed, the air would still be felt and even heard passing through and it did not. but so can tell you for sure on previous times I have smoked an EVAP it just billows right out the vent tube meaning the cannister is not holding the smoke. it’s also a reason when you must close the vent solenoid when checking leaks- so the smoke doesn’t just leave out the vent.

    Would have thought that the vapors would come up and out of the filler neck since the filler neck with the gas cap off is a kind of vent was thinking that some gas pumps push alot of fuel through the nozzle and the size of the filler neck sometimes gets overwhelmed by the fast flow causing the gas pump nozzle to trip off.

      @@SchrodingersBox 2002 Silverado 5.3L When smoke is introduced to the mentioned line, smoke is observed right at the solenoid, not the vent line that’s travels adjacent to the gas fill hose at the gas filler neck. Canister is new but I haven’t tested it yet. Doubt that it's a defective canister. Also wonder if there's an obstruction in the gas fill hose to the tank. The gas neck flapper is intact so not sure what could be causing an obstruction if there was one. I can continuously add approximately 4 gallons of gas before the pump trips, when the gas pump nozzle/handle is in the normal position.

    What's the approximate cost of replacing an evap canister with your diagnostic time included in your labor charge of this car.?

    • @SchrodingersBox
      @SchrodingersBox  Месяц назад

      Your issue sounds like a vent valve actually but the cost can vary tremendously depending on the design of the cannister. This particular one was unusually expensive at $680 total because many of the evap components are on the unit itself. Others I’ve done were in the $250 range.

  • @Tiger2Tone
    @Tiger2Tone Год назад

    Do you ever see cases where the evap canister is saturated with fuel because of repeated overfilling of the tank? I know that you're not supposed to continue to fill a tank with gas after the pump clicks off, but I seem to be the only person at the gas station that follows that rule. Everyone else seems to try to force as much gas into the tank as possible. Am I being overly cautious??

    G'day from Australia, my 2011 Kluger/Highlander gave me the hard to refill fuel for the first time a couple of days ago, the charcoal cannister is selling on ebay for $900 and the vent valve is around $200, 3 months ago i spent almost $1500 on this car that i bought only 4 months ago, and if i need to spend another $1000+ is going to piss me off massively.
    My question to you is, could i just buy a couple of jerry cans to refill the car and not expect to have any problems at least for a while, as i have read that the cars that have these can run without them, that's the charcoal filter, not sure if it can still run without the vent valve though what say you?

    Matt, let me "pick your brain" if I might. First, I have done my diagnostics on my own car because of a physical limitation (back) I have trouble getting underneath in tight places.
    I have a 2012 Hyundai Azera that takes gas just fine... providing the tank is already below half a tank or so. If it is above 1/2, especially 3/4 or greater, it acts just like a very clogged line or canister. With a lower level in the tank it fills just fine. I even tried with the car running to see if the evap solenoid was open and engine vacuum would help. It did not. The car has only a little more than 50k miles. Also, pulling the nozzle part way out to allow some venting doesn't help, either. I found nothing helpful for this using my scan tool.
    Any suggestions? Thanks.

    • @SchrodingersBox
      @SchrodingersBox  Год назад +1

      it is likely still a partially clogged evap that is made worse when tank is filled because the higher fuel level compresses the vapors tighter. the same procedure I showed would have to be used.

I now have a good variety of test equipment and am working on developing the knowledge to provide advanced diagnostics. You have helped a lot along with a couple other teaching channels. I've been providing some troubleshooting for a few people and it's going quite well so far.
      The goal: create a better me, keep my mind active and firing those neurons by actually thinking, make enough extra money to pay for all of this electronics, and mostly help others by giving a correct, low-cost diagnosis to those who can't afford to pay a high priced shop an exorbitant fee for changing parts.
