Picture This ---- I learned a little something when I was teaching a little something Picture This
(A lesson learned while teaching)
Years ago my younger brother came to work for me. He didn't know a thing about cars, but was willing to learn all he could. Teaching new techs is an art that most shop owners have to learn to do, but teaching your little brother can be a chore and can test your patience. I muddled thru it all and taught him what I could. I was sure at some point in time the two of us would butt heads like brothers will do, and he would take his new found skills and move up in the rank and files of the automotive technical world, but in the meantime it was his turn to learn from his older brother.
When he first started I would walk him thru each step of how to diagnose a certain system in a car. A lot of times he would have questions, and I'd do my best to answer them. He learned quickly and was really sharp at picking up some of those little details that are harder to teach, because you tend to forget to mention them while you're teaching. Mainly because you are trying to get to the solution as efficiently as possible, and you neglect to bring it up. Such as: "always test your test light connection before testing what you're testing, or don't forget to check for all your tools before you pull the car out of the shop…." Things like that.
One day we had a truck come in with dual fuel tanks on it. The gas gauge wasn't working and needed some attention. This was a perfect opportunity for Junior to learn a few of my short cuts on these old models. It was an older Ford, in which the tank gauge ran thru the tank switchover button. It was rather easy to pull it out of the dash and connect to the gauge from the back of the switch.
Luckily it was the typical problem I've seen a hundred times in the past. The switch connections would melt and the tank wouldn't switch from the front tank to the rear, and of course the gauge wouldn't move either.
After locating the correct leads to the gauge and to the tanks I decided to show him how the gauge worked. I hooked up the one of the tanks to the crossover lead that would supply the signal from the tank to the gauge.
"Ya see this, that's the lead to the fuel gauge in the dash, and this is one of the tank wires. I'll connect these together and we should get a reading on the dash," I told him.
He was watching intently, taking in all the wiring diagram information, the location of the wires, and how I was bypassing the switch. He was fascinated with the flow of the current and the way the gauge would respond. I even went as far as moving the gauge from full to empty by opening and closing it to a ground signal. While I had his attention I filled him in on the two types of gauges that were used back then (bimetallic and magnetic) and how low resistance on a bimetal type gauge would read near a full tank, while a magnetic gauge would read close to empty. Change the resistance and the gauge would/should read accordingly.
"So, if we put gas in the tank the gauge should move right? That way we could check the sending units in the tanks too," he asked me.
"Great idea, grab a gas can and let's add a few gallons," I said, excited that he was so interested in the project.
He grabbed a can of gas and poured a few gallons in the tank. I was watching the gas guage carefully, but there was no movement. I knew I was on the right wires, but nothing was happening. Now what? Are there more problems?
"Crawl under there, and check to be sure the wire color is correct," I yelled from the cab to him.
"Yep, it's the right wire on the tank."
"Well, we might have to pull the tank; it's not changing the gauge readings up here."
"Before we do that let's add some more gas, maybe we didn't add enough," Junior tells me.
I thought I better go back and help hold the funnel, while he poured the gas in the tank. Unknowing to me, all this time my wife (who was the office manager) was listening in on the whole thing. She likes to keep tabs on me, and make sure I'm not going into one of my usual rants or having a fit because I had to explain something over and over again to little brother. This time she was standing at the corner of the shop just behind the truck with a camera. "CLICK", I heard the camera shutter go off and she was back there laughing like there was no tomorrow.
"What's so funny?" I asked her.
"You two idiots have been putting gas in the wrong tank. You're on the front tank, and you're putting gas in the rear tank," my wife answers, laughing hysterically.
About then the camera "clicked" again… this time it was an action shot taken at precisely the exact moment when these two idiots had that dumb struck look on their faces and realized what they just did. The shot had both of us on our knees, one holding a funnel and the other with the half empty gas can, and both of us staring right into the camera lens. Couldn't have set it up any better if you tried. The picture clearly showed the side of the truck with both fuel tank doors visible and there was no doubt which tank we were putting in the extra gas. I guess it was one of those things I should have mentioned when we were checking the tank senders… make sure we are both on the same tank.
For years that picture hung over her desk, and anytime I thought I was so smart she would point at the photo. Usually with that typical smirk, usually shaking her finger at me and of course the laugh… she had to laugh, but it wasn't all that funny until she had me laughing about it too. Ok, Ok, I'm not perfect... and now my little brother knows it too. These days he's a top notch tech at a dealership, and I have to call him on occasions for some help on how to solve things once in a while. Oh the photo… uhmmm… what photo?? Somehow it's missing… haven't seen the darn thing in years. But I guess I really don't need to see the photo … the wife has a pretty good memory... she reminds me just how smart I think I am every chance she gets.

Article: Joe Friday Diagnostics - AGE check--remember Dragnet with Sgt. Joe Friday? Here's my version of the Sarge diagnosing a carBy Gonzo
Joe Friday Diagnostics "How would Sgt. Friday explain auto repair and diagnostics… que the music: " The story you’re about to read is true; the names have been changed to protect the innocent. Monday morning, it was cold that day. I was working day shift out of the repair division. There’s a suspicious vehicle at the front of the shop. A customer walks in the door. I’ll take it from here. I’m a mechanic, the name’s Friday. It was a 2003 Ford, 5.4 liter, fully loaded and sounded like it was running rough. The lady came to the counter. “Good Morning ma’am, what can I do for you,” I said to the complaintant. “Yes, I’m here about my car,” she answered. “There’s a problem with the car, I see. What can you tell me about it?” I asked, in my usual non-threatening, but confident monotone voice. “I was on my way to deliver my recyclables to the east side collection area, because I’m a concerned citizen you know, when my car started to make a coughing and clattering sound. I thought I would bring it in to have it checked out,” the owner answered. “Coughing and clattering, hmm, not a problem. I’ll get it investigated, I can interrogate the pursuant this morning, especially for a concerned citizen such as yourself,” I answered while maintaining my professionalism. “Well, do you need any other information from me?” she asked. “Just the facts ma’am, just the facts,” I said. “The check engine light came on,” she reported. “This could be of some help. Sounds like a possible 0300 (engine misfire). But I’ll check it out first, I’ll need to finish my investigation in order to give you any proper results,” I said to her, while my pen was busy jotting down the facts onto the always present handy notepad. She left the car with me for further interrogations. Using the scanner made the results easy to locate. It wasn’t long before I got an answer. It was a P0302 in progress… misfire on no#2 cylinder… normally an open and shut case. 09:30 Am, working on the assumption that the perpetrator was somewhere near the 2nd cylinder; I went in for further investigations. I checked the usual suspects. Pulling the plug didn’t yield any new clues. The plug was good and answered all the standard questions. The coil was a more likely suspect; a simple test could answer the problem. I’ll set up a little sting operation by using a decoy. Taking the nearest coil and replacing it with the suspected faulty coil, and put the known good coil on the other plug. I was hoping to see the miss move to the other cylinder. It didn’t. In fact it was gone. 10:05 Am, Now the challenge was on. I’ll have to go back over my facts and check the crime scene again. There’s something I must have overlooked that might be the key to this investigation. Two things come up as good possibles; the connection or terminals at the coil, or the spark plug boot attached to the coil. The plug boot had a good alibi… it had just been changed, in fact so was the spark plug. That left the coil connection. A more in-depth interrogation of the connector is needed. My years of technical diagnostics work told me to look closer at the wire and the connector. The guilty party in this case appears to be one of the wires at the connector. It was barely hanging onto the housing. Only the plastic sheath was still connected, and the wire itself was not answering to any of the standard questioning or interrogative tactics. Under the intense glow of the high powered shop light the investigation continued. Resorting to some strong arm tactics I pulled on the wire while using a few choice investigative words, the plastic sheathing kept getting longer and longer. Soon, it snapped under the pressure to expose the desperado for the perpetrator it really was. 11:45 Am, The repair was completed, and tested to verify the repairs were effective. The car in question was back with its rightful owner by the end of the day. I now can close the file on this one, another job well done. In conclusion: With the P0302 in question deleted from the computer history, the coil connector was then convicted of failure to cooperate. With her car back on the road she could once again be a productive concerned citizen of this great metropolis. Case closed and now, back to the front desk waiting for that next problem to come through the door. This city is full of broken, non-maintained, and poorly running cars. As a concerned citizen I’ll be on the lookout for these suspicious misfires and other infractions of the auto world. There are thousands of men and women in this city, who know that being an auto tech is an thankless, grease covered job that's done everyday without any fan fare. Then again, I'm part of that glamourless, grease covered world... my names Friday, I'm a mechanic.

The following are posts I made on the AOCA website outlining an issue(potential nightmare) we had on 2017 Chevrolet Colorado:

Total Posts: 83 Feb 8, 2018 3:03 PM Unfortunately, I believe this is exactly what this may turn into for shops and consumers. We recently had a report of an oil filter failure on a 2017 Chevrolet Colorado with 13304 miles on the truck and the issue occurred 400 miles after our oil change. Customer had a check engine light come on so he headed right off to the dealer to have it checked under warranty. It had a VVT code stored and the dealer started looking into the issue. They found the filter failure and sent a picture of the image off to the customer. We used a Performax P0171 filter. The customer sent me the attached image of the obviously failed filter. I am immediately highly concerned, but the dealer is being unusually understanding of the failure. We spend some time with the service manager and find out that their appears to be an issue starting to show up on these vehicles, where the stand pipe in the filter housing is coming off with the old filter and being disposed of without the techs knowledge. We had great video of the oil change and their was nothing visible with the old filter as it was removed. The premises is that without the standpipes restricting/diverting functionality in place, full oil flow is blowing out the filter and the everything flows right down the filter housing port into the cylinder heads and remainder of the motor and plugs up components and passages. We asked for a picture of the filter housing and received image 2 attached. This appears that it may be a problem starting in 17 model year, but i can't be sure of that yet. I am digging for additional info now and will update as more information becomes available. Randy_Lucyk

Total Posts: 83 Feb 9, 2018 7:59 AM This appears to be both a GM issue and a in-shop issue.
Now that I see the notification GM released last week, i believe this issue occurred at the original oil change prior to the one we did. As I said, we had great video of the open end of the old filter as we removed it from the vehicle and I don't believe this stand pipe could have possibly been inside. Their is also no evidence of the tech struggling with anything "down in there" other then the normal A/C line interference issue. .
Looking at the design and the A/C line interference, I suspect that the stand pipe is being knocked loose as the filter is being "angled" around the A/C lines to get the old one out. I suspect the oring on the stand pipe is the only thing holding it in the oil filter housing. Once the standpipe is disposed of, the housing has to be replaced, as the stand pipe is not available separately. The housings are in short supply with only three left in the country on dealers shelves and none in Gm distribution centers. Their is a new part number for the housing and those are not available yet. Original pt# 12675707 and new pt# 12682014.
Looking at the attached illustrations and notice, it would not be easy to completely miss the fact that a problem was evident. The stand pipe looks too big to me to be easily missed. I suspect it is plastic and the words "housing cracked" was mentioned in the conversation with the service manager. I wonder if the stand pipe is actually cracking during removal of the filter, making it difficult/impossible to reinstall. If we did not do it, then why the old filter had not failed yet ours did, comes into question. Cold weather "full oil flow" was also mentioned in the conversation with the service manager, and those were the conditions at the time of the failure.
The images also create some questions for me. The new housing does not appear to be identical to the OE installed housing, so is it an already redesigned housing? The filter bulletin in the Napa/Wix box talks about an update to the filter to include a check valve in the top of the filter. Our old filter does not appear to have this check valve, the Napa/Wix does and our new stock P0171 filters also have it. Looking at the design of the stand pipe in the new housing, it would almost appear that the small nipple on the end of the stand pipe might make more sense if it fit into the open hole of the old filter. The stand pipe design almost seems wrong for the filter with the check valve, unless it is shorter than it looks and never reaches the upper end of the filter. Would be great if the next shop to have one of these off would post some additional pics to try and help reduce confusion.
Based on the notice from Gm, this does indeed look like it could get ugly. Although, this dealer covered all the extensive engine repairs under warranty(heads pulled, all new timing components, cleaning passages), i am not convinced all dealers will take that approach. In my case, it was nice(incredible?) to see GM step up and take responsibility. It helped that my customer (owner of the Colorado) retired from a GM primary supplier dealing with issues exactly like this for the later half of his career. He knew the right people to call to get the info needed to drill down to the root cause.
Here is a link to a question on Quora that I supplied an answer to and so far it has gotten over 3,700 views and 75 upvotes. Thought that you might be interested in reading it.

New member here.
I wanted to pose a question to the forum here.
Which types of leads are most likely to turn into sales for you? Put another way, what is your best source for generating new business? I don't want to know how you advertise, I want to know know for example if phone calls are more valuable than web leads, or which types of leads have the highest closing ratio for you?
For most people here and in most industries, its unanimous that word-of-mouth and in person interactions are your most likely sales but besides those what is the most reliable? Web leads, phone calls? And when you do advertise do you push people to the form of contact that your most likely to close?
The reason I ask is because I see people just advertise their website with no phone number sometimes or some people really push people to call.
Do you find that people who call your shop are more likely to come in than people who might come from a web lead such as an online form?
Thanks in advance for any input.
