Buick LeSabre - Large EVAP Leak
video description
Update: It wasn't specifically called out. Dangit! I figure when the customer is finished putting gas in there (or fiddling around with the gas cap for any reason) they may twist the filler neck into a non-sealed position. and before ya know it you've got a large leak. Explains how it's intermittent and not readily repeatable by Mr. O. But rest assured, the new clamp and the tightening will likely have fixed the problem - so call this one done!

I’m not in 100% agreement with the ending. I think you should present your findings to the customer, 100% honesty, including that the part on the engine fails quite often, but tests good now, and let them at least have the option of you replacing it preemptively, and save them making another appointment later. Seeing that it’s a Buick, I’m going to guess it’s a retired person and they have the free time, but still. Any time you create a deviation in someone’s normal life routine (by forcing them to come back a 2nd time, you open up the possibility of altering their life in an unfortunate way, because they’re doing something and being in a place they wouldn’t ordinarily be. Something to think about.

Got a chill down my spine watching this one. From the years of running a shop, there were at least half the customers who'd be back when the intermittent finally failed. And even though you told them it was working at the time you saw it but might not be in the future, you'd get the rant of I already brought it to you once! You're scamming me by making me come for another visit. Considering how many crooks are out there and how little people understand about their cars, I guess I can see why they'd think that. But it makes it hard to run an honest shop.

I noticed when you were fiddling with that cap the neck was realllly loose. I don’t know if you had removed the old clamp at that point or not but if it was THAT loose it probably could throw a gross leak. it’s virtually the same as the gas cap coming off IF it was that loose. And McCoy is right he realllly had to turn it. you could hear it very loudly in the backgroundit was so loud it caught my attention for what that’s worth. I bet you it was cross threaded on there and that would maybe throw a gross leak. I THINK. we’ll see!

I was a Toyota Technician for 47 years, retired in 2016. I watched you replace a crank pulley the other night and you were very concerned about damaging the radiator by bumping it with a tool or the puller you used. I had a piece of cardboard that I dropped down the engine side of the radiator and held it in place with a couple pieces of Gorilla Tape (Not a Sponsor) at the top, Sure saved me some grief over the years. By the way, you would have made a great Toyota training teacher at the Toyota regional office in Cincinnati.

Aren’t you tired of bing and moaning about lick’em and stick’em shops cause as sure as hl I’m tired of listening to it! It sure sounds like you have a HUGE axe to grind, how about if it wasn’t for the so called lick’em and stick’em shops you wouldn’t have made the couple hundred dollars or whatever you made on this job: according to you they would’ve just junked the car and not fix the evap leak because the car is not safe. We get it: you are mister correctitude, good for you!

I had one of these cars over the summer with an evap code. I ended up tracking it to the top of the fuel tank I think it was a hose on top that wasn't sealing anymore. There's a spot dead center of the tank you can get a bore scope in that fuel pump access hole and go over to the left some to see it. If I can get a diagram tomorrow I'll update you on exactly which line it is. The only issue would be how rotted that car is because the only way to access it is to drop the tank.

Would you consider a video about the scan tool you used here, why you picked that one, what it can do, etc
Is that the same one that you have used the cylinder pressure transducer with That looks very useful. If so, does it read the crank or cam position sensor and show the pressure-vs-crank position
Can it do any reprogramming I mean air/fuel ratios, spark timing.
Your opinion on the scanner would be meaningful.
Good videos, thanks.

Some time have McCoy do a Diag video with your guidance. 40 plus years ago as a young learner I worked with a guy like you who taught me a lot. More and more when I had asked too many questions or the shop was busy, he'd say scope it out He'd let me struggle for a while then step in with a pointer or two if he noticed I was going in the wrong direction. Ultimately this would lead me in my own direction to the solution. That way I never forgot.

I just had a p1450 code. Nothing wrong with canister, but we changed out the purge valve per mfr's instruction sheet. One other thing we did was to clean the capless fuel filler pocket and spring hinge with compressed air and WD-40. Apparently they can refuse to seal. There's also a rubber seal on the filler door that I think gets worn and lets water in to the tank and dust into the flapper's spring hinge.

The 3. 8 was a damn good engine, Holdens in Australia used them for many years from the VN - VY Commodore and they were reliable and robust. Then Holden introduced the 3. 6 Alloytech in the VZ Commodore which was an absolute POS with soft valves, no oiling for the rear valves relying solely on splash and constant timing chain replacements every 150 ks.

If that was my car, my best friends car, or my mothers car I would put a high quality gas cap, purge solenoid and vent valve on it and send it. They are not high dollar items, and you really aren't just tossing parts on it. They are high failure items that can definitely be intermittent. Better than having to come back to it and touch it again.

I really appreciate the fact that Eric is showing Mccoy the proper way to do business and not how to play wild bill hickock with the parts revolver even though it potentially cost him in hrs on a job that he could have had like 99 percent of the mechanics that i've delt with would do Eric O is the best mechanic i've seen by far

I just throw a purge valve and a vent valve at it, and put o ring grease where the gas cap meets the filler tube, fill the tank and wait two weeks. Some cars won't run the Evap monitor until all other monitors are fully satisfied. And if the EVAP monitor is OFF, as a full tank comes down to 75%, it will turn ON

Youve got more auto knowledge in your pinkie than I will ever have in my whole brain, but i am not down with the soapy water spray on the pump access door, about 1/4 cup What if there WAS a large crack there lots of water into the gas There are foaming soap dispensers that might be better. all foam, no water.

Thank you for allowing McCoy an opportunity to work in your shop. My 16 year-old son is lucky to have found a shop to let him work and learn there as well. We parents and forever consumers thank you for teaching them a trade that is and will almost certainly be necessary for decades to come.

Man, I wish MORE auto techs had your moral compass. they aint techs, they are parts cannon operators. that being said, I am SOOO glad I dont live in the PRNY, where they're sooo nit-picky on rust n enviro concerns, especially consider'n their hypocrisy of insane use of salt on their roads

McCoy I’m sure is appreciative of Eric O, but the kid has no clue the level of instruction he is receiving from an industry leader such as Eric O. And that’s not a knock on the kid. He’s one of the luckiest young men in that craft to learn from an industry titan.

I bought a new 1989 LeSabre and kept it ten years with 121 thousand trouble free miles. Only qualm was the alternator that quits every two years due to the alternator placed in the middle of the engine where the heat is. At least it is in an easy place to access to.
