Dave, you should follow through on these videos, even if it’s just a minute or two summary at the end of here’s what ultimately happened and here’s a clip of the vehicle running and driving at the end. Lots of these videos end of cliff hangers!
Yea , totally agree. 👍
Yeah, it's like watching an action movie but going home 15mins before the end.
I agree also.
I concur
@robertmiller341 surely more of Dave is a win for everyone
"I don't want to spend any more of his money until he knows that this is what it's going to really cost" This is one of the golden customer service skills spot on
Yes 100% would make a great channel even more so!
He’s not angry man he’s a man that doesn’t like shabby work. I completely understand this man. Good job.
I had 25 years with vw! I know where he is coming from!
He's Been Doing it long enough to understand that doing a half ass job just makes everyone unhappy & miserable.
Life's too short ! Do it Right the first time. Allways the Right way to go !!! You always end up spending more doing it the second time than if u had just done it right the First time. 😉
Yep. He wants to do it right the first time. This person didn't do it right the first time and now he gotta fix it. The knowledge he has and his son is amazing.
Vee dunes VW I prefer older diesel @@bentetzner4263
Yeah I know the exact tone in his voice. I was a boat tech for 3 years before becoming a wireman and our master tech used to sound like this all the time. If one of us made a mistake he wouldn't get mad at us he'd just get that disappointed tone.
My father, who was an aerospace engineer for NASA for over 4 decades, had a saying, "You only get one chance to do it right the first time." A motto ingrained into my soul since my earliest days, rest in peace Pops!
Was your dad ever on the moon?..
@@Shane-zx4psif he went to the moon, he'd be an astronaught, not an engineer.
@@alanjordan9772. I’m kidding with you dude, I’d be proud also👍
@@Shane-zx4psI'm not a dude, I'm a space station.
@@alanjordan9772 I know you are.🤔
Dave's "Disappointed dad look" sends me straight back to the days of my youth and my lousy report cards.
😂
Me X12 lol
I felt that😂
Einstein had lousy report cards too
You Sir are no Einstein...@@pzm958
All this kid can do is learn from his mistakes. Hopefully it does not deter him from any further mechanical ventures. Working on your own stuff is a very valuable skill, especially nowadays.
Yes, but you have to know your limitations or you're going to go broke practicing.
@@Mayamax3 That is why you practice more difficult procedures on beater project car when you have money to drop and not do it with your main vehicle.
Couldn't agree more
It could be fun to watch them build his motor so he can learn the process in doing it right... invaluable teaching moment in life...
@@Mayamax3You expand your limitations by diving in and tackling new projects, sometimes that results in a failure.
It is however a pretty bad idea to practice and have your failures on valuable vehicles/engines. Play around with beaters for sure, not the daily.
You are perhaps the most ethical repair shops I have ever watched! You are a testament to your integrity and honesty! Kudos!
I worked for Cummins Illinois Engine Sales/Chicago for several years starting in the '70's and they were a superb engine rebuild shop for Cummins (obviously). We rebuilt EVERYTHING Cummins, ground our own cranks, completely machined blocks, rebuild heads and all engine subassemblies and every engine received a full, several hour dyno test before it left. When Cummins Engine Company started their ReCon program it was based a lot on what was done at our facility. Cummins Illinois is no more, bought out by Cummins Engine in early '90s' and is a mere shadow of what it used to be. So, I'm very familiar with what you guys do Dave, keep up the good work!
That's a great story. I work on Cummins everyday on the semis.
@@StrongerThanBigfoot Yep, we had about 12-15 bays for trucks too.
I'm no diesel guy..but that must what old timers were talking about .when they mentioned Cummins Engine. Was very stout / tough Engines..Kool story also I love hearing. About historical times
When I did an automotive industrial course at tech 30 years ago which was an introductory course at tech in New South Wales in Australia ,it was a prerequisite course to becoming a diesel fitter or mechanic & you could become a mechanic who services light vehicles as well,one of my teachers was going through with us how backyarders who are like that tend to get dirt in engines when they rebuild them & while they might go alright for a while they end up failing or wearing out prematurely.
He was emphasising how important it is for everything to be clean including the bolts because if the threads are dirty on the bolts & inside of the engine block, etc you will not be able to set the proper preload on the bolt & they may come loose.
For bolts which are bathed in oil such as the connecting rod cap bolts he suggested doing what the manufacturers tell you to do which was to coat the threads in oil prior to refitting the bolts to get the proper preload of the oil bathed bolts.
Even when I repaired power tools it was the same deal, everything had to be clean !
@@RussellBooth1977 I had a mechanic do a head gasket job; a few weeks later, the oil light came on driving at freeway speed and the engine became very noisy; I had the vehicle towed to a different mechanic who determined the engine needed a rebuild; he found grit in the oil pump pressure relief valve, which caused the valve to jam, causing complete loss of oil pressure.
My LS3 dropped a seat at about 200k miles. It just barely tapped the top of a piston and it happened while I started it up so I immediately shutdown and it didn't do any more damage. Pulled the engine, disassembled it, took it to a shop to be machined and measure the journals, cylinders, etc. Ordered all the appropriate parts for it and had it all sitting in my living room. I'd already had the same shop rebuild the good head and order me a new head to replace the one that dropped the seat. Sitting on over $10k parts and labor and decided "I can take an engine out, put it back in, disassemble it, and while I can put one together, I don't know the decades of knowledge to do it RIGHT." So I went to the builder with everything and said "you've already done the machine work, I ordered everything from GM and sized on the measurements you took. I understand if you don't want to warranty it but bro, one mistake and I'm out DOUBLE the money and there aren't any LS3 engines available anywhere now." They built it for me and it's been perfect ever since. GLAD I made the choice because I knew that I've learned a ton in my life but as I work in IT and meet other IT guys all the time who don't REALLY know what they're doing, I recognized I didn't REALLY know how to put an engine together. You can't replace 30 years of work, muscle memory, the micron-level touch in our fingers. It can only be hard won through doing the work and doing it well. I went as far as I could go and I wasn't afraid to say so.
A great well written synopsis. With things mechanical, even 30 years experience will only get you so far because every good mechanic can still have unknown 'never seen this before' surprises that can challenge any level of expertise. Lol
On the other hand I've had "professionals" screw up even basic stuff like massively overfilling a transmission I had a shop rebuild. Just because someone does it a hundred times doesn't mean they will do the job right if they do sloppy work. Trusting the wrong people, which is part of what went wrong here, is very expensive in automobiles.
@@0utc4st1985 There are no guarantees. Even in a high end shop most of the fluid changes and simpler odd jobs will be done by low paid entry level mechanics. If they have an ability there and are consistent in doing good work then they move up fast.
Personally I ALWAYS check the work on even proactive maintenance. Dip stick oil level, crush washer and tightened oil plug, are there belt buckle scratches on the fender? Most reputable shops don't like repairs to come back so internal job checking is more likely to take place.
I agree with your point though.
@@randmayfield5695 Putting twice the fluid as it's supposed to have, putting an obviously wrong length of TV cable, not paying attention to the spark plug cables when reinstalling it so the fan chops up one of them......yeah, I don't buy your premise. A fish rots from the head down mate. Most shops in my experience just want your money and try to shove it out the door as fast as possible with zero QA.
I just left a comment with a similar experience, although yours is probably better articulated, I’ll paste it here.
I’m a full time mechanic…I had my own motor go on me in my Cummins, 12V, friend had a 24V motor he was selling, the price was right, bought it, swapped the mechanical fuel pump over (which is a bit of a job, gotta pull the cam and swap the front cover, as well as retime the pump), resealed the 24v, and rolled in bearings…but you better believe before I bought that engine, I did a compression test and stuck a bore cam down every hole I could think of, and when it went back together everything got torqued to spec…and I didn’t touch that oil pump…cause oil pumps are scary. Engines now in my truck running fairly happy, few little issues, but it gets me around and it’s good for laughs(…especially cause I put a rowdy cam in and a big turbo on.) That being said, that 12V is sitting in the garage, and it’s gonna get sent out to the machinist and rebuilt for some serious power. Even though I think I could rebuild it from the crank up, and would probably enjoy doing it, and probably know those engines better than anything else…I’m still gonna pay the machine shop to do the reassembly for me. I don’t wanna have those questions in my head ‘did I torque this, did I do this right’ etc. Even when I can hop on identifix and get every single torque spec and sequence, I would rather pay the professional engine builder to do it.
So much more intriguing than a crime investigation or murder mystery, these episodes are so captivating. Great job! I hope this works out well for the owner (and the next owner).
Engine crime drama is what this engine would have turned into.
Quite a great compliment, thank you very much 👍
Would be interesting to know what happened to the F250 diesel with the bad fuel system and the angry owner.
So….love this vid too…I also strikes me that there is no stupid reality show crap in this channel….no fake personality conflicts…no contrived drama….no fake “breakout” stars…..just real mechanics doing real work for a great boss….I’d be a shame if this channel ever went that way….
Prob one of the coolest customers. Very understanding. I love having customers like that, they understand that your being honest and straight forward.
When I dealt with the shop that did work for me, I didn't haggle over price, just paid what they asked and went with what they said I should do. I got the feeling from them that I was very much in the minority. It's a shame.
Hard to find now a days no trust in any industry really
@dv6195 true but when you find the honest tech or tradesman YOU PAY THEM. Im ex ASE tech commercial carpenter. No i dont need ur cheap $$ to do mechanic work. I only do it 4 those who cant afford it/cars value=shop costs too much. But im honest and ill do it RIGHT. So i may be cheaper than shop but u want a toming belt? Maybe pay me 1000$. Cause its still 2,000$ less than a shop
@@User0000000000000004this is correct way. Once u find the honest ppl PAY THEM overpay them. It will help them remember you. I treat everything with 110% effort and to any rules about it no matter how trivial and thats the person u want. Do it RIGHT the 1st time
Absolutely needs a part 2! I. Still waiting to see what is gonna happen with that cracked crank M156 (6.2 AMG Mercedes V8)!
I am really impressed with Dave and his way of doing business. His customer skills are spot on. There's no BS going on here, just the hard facts. Kudos to Dave's Auto Center.
The knowledge on this man is insane, he called the guy and went through every option down to the cleaning of the engine. And pointed it out that’s crazy
Unfortunately, Dave is a dying breed of man.
That’s normal to do if you’re a good shop 😊
This is why you pay a professional tradesman to build it .experience is priceless. Dave's the best 😊 amazing tradesmen 😊.
Thanks 👍
Came across this site by accident, happy I did. As a former A&P Aircraft Mechanic in the 70's and 80's I really enjoy watching honest good mechanics at the top of their game.
This is unreal how you show every step of the troubleshooting process. By far one of the best auto care channels on RUclips.
Dave I love how you arched back to the "That's what we are here on earth doing learning from our mistakes". God bless you Dave, in a time where mechanic shops are pulling fast ones on folks, you are here bring the Truth to the mechanic world.
One of the greatest quotes that my grandfather ever told me was, “There’s never time to do it right, but, there is ALWAYS time to do it twice.
As far as the comments to the service writer...I dont mind when someone is firm and direct with me when I miss something, it helps so much to know where you sand with your boss. Constructive correction with respect...beautiful. Man I wanna for for this guy.
Dave,
As a mechanic and engine machinist/ builder since 1988, I applaud your sincerity, integrity, and no compromise values of your shop. When you turn out quality, you can look everyone in the eyes and smile.

What doesn't make sense is the 'youtube reality' aspect of this shop. Watching these videos make me think that Dave is the ULTIMATE mechanic- honest, knowledgable, fair and technically skilled. Reading the reviews of the actual shop on google is extremely disappointing. Hard to tell what the truth is.
I almost dodnt click on this, but becuase i was bored i clicked on it. You have a valid point.
Line boring is important.. but i assure you if it wasnt wrong from the factory, is not reason for oil pressure.
And every time he finds a disaster, disasters walk to him to say he is king kong Jesus . Its all show.
I imagine his shop is no different than any other. He may be awesome but guys that work for him are morons yet he takes he blow because it's his shop. Then again there's always people that don't get the answers they want and thus the shop or mechanics are "morons"
I cannot get enough of Dave's content. I wish I had known about him when I started my career. I would have packed up and moved out and begged for a job. Learn it from the best from day 1.
💯 percent. I got my start at a local dealership and the guy I apprenticed under was a bi-polar egomaniac and I found out he did some shady stuff to customer’s cars to drum up more work. I was only making $8/hr (this was in ‘05). I learned a lot, but ultimately I packed up and took a different career path. I enjoy working on cars. Had I had a mentor like Dave, with integrity, patience, wealth of knowledge, and actually investing in his employees,… this industry is hurting for great Techs. Every shop I deal with lately comments on that.
I rebuilt the C4 and 302 in my 72 F100 2 years ago. I had never done a full rebuild before. I bought books on it, watched RUclips videos, and was extremely meticulous with the job. It's been 2 years and it's still running strong. Going to pull the top end apart and inspect the camshaft, lobes, etc this summer to determine if I have any premature wear before adding a supercharger; it has about 12k miles on it so far so I suspect it is entirely broke in, to include the timing chain slacking some(I advanced it 4 degrees just to compensate for timing chain wear over time). Anyway, I wish everyone luck who rebuilds one themselves. It is a labor of love and a very enjoyable process, but you must take your time and do it correctly the first time. Do not be afraid to pull it apart many times if necessary.
Thanks for the share 👍
I really like the analogy between the surgeon and the engine assembler.
At least it's only stuff; doctors and dentists routinely destroy the health of their patients.
@@petesmitt Theres good and bad ones out there everywhere! You have to be picky and know who you are working with for sure!
A sergeon and a mechanic are pretty much the same thing except the surgeon fixes everything while the motor is running.
@@dadigitechman 💯Fact!
Top notch shop owner and don’t forget top notch technicians. Masters of their craft. Honesty and skill. Two things almost impossible to find in the same building these days.
The look on your face when you were talking about cleaning out the oil galleys was priceless!
I been taking notes from every video to make myself a better mechanic. I love the way this guy questions and explains the why and how behind everything. I also have seen many engines installed and never once did any mechanic do a cleaning first when it got back from the machine shop. This channel will be the reason why every mechanic will up their game.
Everyone should strive to be as meticulous and honest as Dave, it makes sense he has one of the most reputable engine shops in the country. I hope to build something this awesome before I kick the bucket
Daves got that reality tv vibe without the reality tv script.
Discovery just picked him up though he's the real deal!
Mr. Dave, I love your content. I am active duty Navy and I am learning so much from your videos. I am not a mechanic, but I do own an 08 Ford F-350 with almost 170, 000 miles. Hopefully, I can one day come to Utah from Elizabeth City, NC so you can repair and upgrade my 6.4 Power Stroke. God Bless!
Every shop needs to watch these videos and see how its truly done
Wow. What a shame. So many guys with the best of intentions end up like this because they simply do not know what they do not know. I used to be in the tractor business and learned how t rebuild gas & diesel engines. Never had a return due to this kind of issue. That was long ago when I was just a young buck. These days I watch Dave's expertise here and will likely end up having his crew rebuild my current engine when the time comes. God Bless all of you good folks.
This needs to be a TV show
Appreciate him taking the time to help the guy work on his own rig. Sometimes you just have to take it to a specialist to do what you can't.
Dave looks just like a surgeon or medical doctor so his analogies and comparison to car mechanics is perfect 🤣
Thanks for that😂. And I do find that comparing it to the medical world helps to make sense of it to the customer.👍
All surgeons are mechanics.
Dave sounds like my surgeon, very thorough.
Old mechanic here,I always learn things all the time,this video no exception.
@Bubba-wx7lp In a sense they are but not literally. Totally different professions. One works on the human body the other vehicles.
Rebuilding an enging is very tedious. I have been working on my personal cars since i started driving. In my 40 and took a stab at in after my work van hydrolocked in my driveway. I did not know what was wrong with it until i had the rod on a table all i knew was it ws knocking like hell one day after i started it. It almost went flawless. I had a rod cap het loose and spun a bearing 2 miles from home about 3 month after the build. Was able to just replace it with no other damage. I found this channel during the rebuild and keep watching since. I got to say i want to take apart my trailblazer engine now, and my wifes town and country after i buy her a newer car. Its a fun process and very rewarding when you can clear all the problems and lights all at once and your engine sounds smoother than you ever remembered.
I've worked in the automotive industry off and on for over 10 years, and I have to tip my hat to Dave and his team for their grit, integrity, and just all-around passion for the industry. I enjoy the breakdown videos alot. The back and forth with customers can be a bit nuts sometimes, super solid the way dave deals with it. Alot can be learned here.
I don't know much about engines, but I love to watch those videos.
It doesn’t take kno longer to do it right the first time then it does the wrong time. You are the man that does it right the first time.
Being a former RAM Dodge tech and cummins guy. All aftermarket thermostats are garbage I only put cummins thermostats in
We all make mistakes. When I was 18 I replaced a blown head gasket with out checking if the head needed resurfacing/skimming to save money. Needless to say it went again very quickly. Lesson learned for life.
Dave, my father was a surgeon. He said he could take a smart mechanic and make them a surgeon. So you could do it!!
Oh that's great to hear! Thank you for the share. I love using the analogy because it really helps the customer comprehend the situation.👍
Dave with the medical lecture lol
Doctors and Mechanics are in the same profession. They fix and maintain a machine. The human body is an incredibly complex machine. Vehicles are getting more and more complex. I want the Model T days back when things were simple.
@@normtheteacher5485 did you just compare turning wrenches to an actual surgeon?
Yes I did. Mechanics is getting very complex with all the electronics and anti pollution sensors and computers. Mechanical expertise is approaching the level of a Medical Degree.@@OutdoorCanadians
@@OutdoorCanadians you again? I thought you unsubscribed😂😂😂😂lol. Just poking fun...
Had a gall bladder removed…. Doctor left a 10mm socket in me.
It’s for sale
I wish there were more small to medium size business owners like this. The piece of mind it gives you as a customer is worth every cent
Looking forward for the Part 2!!
Dave, I was a mechanic for many, many years. NIASE Master and dealer wrench, now retired. The hardest part was not fixing the cars, I found the hardest part giving disappointing news to customers, especially when I could tell they didn't have the money. It was never fun to tell them the bad news. I always thought it better for myself to explain to the customer of the issues rather than a Service Writer being the delivery of the news. I appreciate how carefully and thoughtfully you deal with this issue. Much respect!
I was the same and always undercharged
Dave, you have the best darn videos on YT. PERIOD!!!!!
I have a 5.9 cummins that i work on myself. Im not a mechanic and I don't wanna do the job, but I don't have the money to take it to a shop. Thank god for you tube, definitely understand why guys try and do the work themselves.
Customer - "Get it running so I can sell it"
Dave - "Yeah we'll get you a price on one of our new long blocks"
Not what he wanted Dave 😂
i'm getting a very suss feeling about the guy just wanted to pass his troubles down tje road. He may find Dave is gonna not play that game.
@@stevewhite3424Exactly. A sus rebuild done with significant corner cutting or lack of skills, then wants Dave to effectively just slap it back together once he’s discovered the issues, so he can sell it quickly. If I was Dave, I’d be concerned too. No doubt once the bare minimum the customer is willing to pay has changed hands, it will be sold as “Totally rebuilt engine, no expense spared”.
Way back in college (early 90's) my grandfather and I "rebuild" my 2.2 engine in my Dodge Aries K. Blown piston. Got it running, messed up the vacuum tubes, and it burnt a quart of oil every 2 weeks. Lesson learned.
The problem with most shops is the lack of communication but the way you handle these situations in and of itself is enough for me that God forbid anything happens to my engine, I’ll box her up and send her to you guys all the way from NC
I love Dave, he reminds me of a true old school New Englander. I'm from Massachusetts and my family has had a shop going in Sudbury since 1952, my dad started it and now after two generations his grandson is running it. I was just out there in Idaho visiting my grandkids in Sun Valley where my son lives. I drove by Dave's place on I15 on our way to visit friends in SLC, but couldn't stop in and visit because of our tight schedule. Next time I'm out there I just wanna shake your hand. Your a good example of what a fair, honest businessman is. My Dads motto at our shop was "test work, not guess work" and "do it right". Lastly , I've learned a lot about diesels and procedure by watching your videos.
Definitely need a part 2 for this video for sure!
Love how you treat the lads that now make you money and to teach them with a firm hand , to care for the work they do , they FIND you as a leader to their way in this world. Nice work Man! Your people are great and as a German man in charge of a big rag trade company said to me once , {"the fish stinks from the head down" So you got this!
Besides not getting it cleaned the main issue just wasnt following the directions exactly, the loose bolts most likely werent torqued to the right spec, same with the oil pump. Its good to learn how to do these things the right way.
So many people pay no attention to torque values. Lots of mechanics will slap your wheels back on and go to town torquing your wheel lugs with an impact. Meanwhile they make them so tight that it can distort your rotor causing uneven brake pad wear, put additional stress on wheel bearings causing them to fail sooner, etc. There’s a reason why OEMs specify specific torque values on various bolted components.
I own an '04 Dodge Ram 2500 similar to this one - HO motor with the NV5600 transmission. It was just shy of 350K miles, and the motor was just done. Tons of blowby, exhaust gas and oil was dumping out of the blowby tube, rough idle, loss of power, rolling coal like a locomotive. I found a reputable diesel engine rebuilder - the only one of his kind within a several hundred mile radius of me, and decided to go for the full overhaul rather than buying a new truck. It was an out of frame complete overhaul. New pistons, bored .20 over I believe (rods & crank were still good as new), new valves, all new fuel system including new common rail, pump, and injectors, a new aftermarket exhaust manifold, plus a Valair dual disc clutch (didn't charge me any labor for the clutch), and probably a bunch of other things I can't remember. All for $16K and some change. So far so good. If I lived in Utah I'd have brought mine to Dave for sure!
When I studied an introductory automotive industrial course at tech 30 years ago in New South Wales in Australia which was a prerequisite to becoming a diesel fitter or a diesel mechanic or you could become an automotive technician who services & repairs light vehicles one of my teachers was talking about how a lot of backyard engine builders worked in dirt meaning that once the engine is rebuilt,it might go alright for s while but it will likely wear out or fail prematurely.
He was talking about how the bolts & the threads in the engine block & cylinder head, etc should be cleaned & free of dirt, maybe blow the threads out & also clean them with a thread tap or a die nut because dirt will cause the bolts to come loose or the specified torque figure cannot be achieved when torquing up the bolts if they're dirty.
Also that generally a manufacturer will instruct you to coat bolt threads such as bearing cap bolts with oil prior to installing & torquing up the bolts since they're oil bathed.
I know that I have rebuilt a few engines or I have done some major work on them & none of them have failed even when I have had half of the engine stripped down & outside in the backyard.
It's the same as when I repaired power tools as an apprentice, everything had to be cleaned in a parts washer,all the old grease had to be removed from a gearbox of a grinder or a jackhammer because if any metal shavings or bits if needle roller bearing was left in the gearbox & piston assembly some of that grease would work itself down into the piston assembly & tear up the new piston seals
Must say gents. You sharing your mechanical acumen and expertise go a very long way to preserving this science . I would be an honor for anyone to learn and study under your guidance. Your content is always inspiring. Sincerely MFS
Hi Dave many thanks for your fascinating videos of what you do in your shop. It is clear that you and your family have a real passion for what you do. It is also fantastic to see how you implement your Christian principles within your business with both the customer and your employees. You really do care about what you do. It was lovely to see you giving back to the next generation of young mechanics as they toured your shop and listened to your advice. May God richly bless you in days to come as you continue to serve him in your daily life. Watching in Northern Ireland.
David, your doing the right thing. You should tell us how much labor on each job is and how much each technician gets paid. Doing the job.
This is my favorite yt channel. I wish I could work with Dave. I'm sure the learning would be constant. My first job out of high school was rebuilding cylinder heads out of machine shop.
I worked for a flooring company called Unlimited coatings, Dave was nice enough to let us do his entire shop and the showroom which polished. Dave is an amazing mechanic and a super nice gentleman. I appreciate the experience we had at that job.
I run an '08 6.7 Cummins in my '08 F450 conversion. Having never been around a Cummins engine before, I did a ton of research for the conversion project. I saw where some were says the rear of Cummins head dead ends and doesn't allow for the coolant to circulate, thus causing hot spot. I found the bypass kit to be pricey for what it does. Then I came across an ATV cab heater thermostat housing to help keep ATV Cabs warm. the unit has an input, output and bypass ports. I tapped in to the rear water port on the head with a 5/8 heater hose which runs up to the ATV thermostat housing input port. The side port of the unit flows the pre-thermostat coolant back at the bleed off stand pipe completing the factory loop. When the coolant temp opens the ATV thermostat it allows water to flow into the radiator return pipe. Post the stock engine 190 degree thermostat. The ATV unit came with a 180 degree thermostat which I used at first. After a short period I noticed that the engine was not reaching the 190 degree operating temp in normal daily driver conditions. From which I deduced that the ATV 180 degree was opening and bypassing as I had hoped. I then changed out the ATV 180 thermostat to a 195 degree thermostat. Now the stock 190 degree opens and then the ATV 195 degree bypass opens as needed.
Engine runs a constant temp range of 190-204 degrees. Towing a total weight of just under 30K lbs. Hills or no hills.
I'm not a mechanic so I can't believe I watched the whole thing!! An excellent video. " You da man Dave ".
Friday:
Pay day 😊
Life is good.
Thank you God 🙏.
I think the customer needs to be on the operating room and be part of the heart transplant team .
He deserve it . He sounds like he love his truck 🛻 ❤
In today's world of filler words and people talking to hear themselves speak. I found it rather refreshing to listen to someone speak so succinctly 😁
I feel bad for the customer but you know what is great? The fact that we have this technology nowadays where you can email the man shots from your video camera and borescope pictures. It's another great tool to ensure the customer (and technicians too) that everyone involved is being totally honest and honorable. Love this channel. 👍🏼👍🏼👍🏼
Mechanics shouldn't have to do that. Do you expect video evidence from your doctor when he tells you that you have cancer, of course not
@@COBRO98 Of course they shouldn't have to, and they don't have to. I'm just saying that it's a nice piece of technology to have that you're able to use if you want. As far as my cancer diagnosis goes: I guess I wouldn't demand video evidence but I would probably review some CAT scans and MRIs with him or her or whatever tests they run. I would certainly be looking at pictures and videos if my surgeon told me that I absolutely needed a new knee or a new hip..... of course I would want to see that. And I bet the doctor wouldn't have an issue showing me. But I wouldn't HAVE to see it necessarily. That's all I'm saying.
When I started as a technician back in the early 80’s, the man who taught me everything I know always said, “Do it right the first time”. When you cut corners it always comes back to bite you.
I learned: it's ok to not 'know' > go gather knowledge & find out - the right way.
Problems with projects like this one has, comes from too many different mechanics having their hands on the build. Something always doesn’t get done or fixed or checked because of poor communication and just too many points of possible issues if the correct procedures aren’t followed. That’s why it’s essential to find a shop with the equipment and with mechanics experienced in repairing the exact problem that you have and having a single pair of hands and eyes in charge of the job.
Dudes a good leader, the guy who comes in an asks the critical questions.
15:00 sucks to have to tear it down. Although, At least he didn't go pulling a trailer down the road, or take the fam on a trip or something. That would really suck. God Bless y'all for helping your customers out and teaching us too.
ALL of the time I have spent watching Dave's videos has been time well worth it. Enjoyable as well as educational. Key is that Dave is a very moral person/ business-owner as well as a most knowledgeable in this business. A pleasure to watch and learn.
Thanks Dave!
Another ‘can of worms’ taken care of by your dedication and honesty, Dave. The biggest takeaway I got was communication, communication, communication! Enough said. Great watching you guys. Cheers!
I love how you detail the problem, the cause, and the solution. People should pray they have a mechanic that is that thorough. That's why we watch this channel!
MAN I don't understand, if I was anywhere in 1000KM radius of Dave, i wouldn't even look at other shops.
Wouldn't it be a wonderful world if everyone ran a shop like dave..
These instructionals make me think and use my automotive knowledge in a way that works for how I learn. I love using my limited knowledge to learn new things automotive and that's why I enjoy Dave's channel so much. The more you learn about a topic the more you realize how little you know.
Hope this Vehicle owner understands how lucky he is to have Dave's Auto Center Taking care of his Cummins. That service writer definitly got a wake up call. Nice Work, Dave.
Its really wholesome to hear the way you talk about your sons. I wish my dad was as proud.
Stop being a lazy failure then and be might be
I hope the customers get a discount for getting their failures posted online. You are right everyone who likes engines would love to build one so posting their failures as anything other than a misstep in the right direction is low.
The customers name is not posted. Good learning video for rebuilders.
Cool speech, now go start your own channel, get some likes and shares, get the algorhythim putting our content into peoples feeds, get lucky and go viral, stackup a pile of subscribers, stay consistent, maintain quality, maintain your integrity, keep it from violating youtube rukes so you can get it monetized, uae the money for somethin good that gives back to your audience so you dont alienate them, have guys that you dont know personalky that post up in the chat that are loyal to you and that will defend you in the chat. At thst point you can tell a guy how to do whatever thing you do to do the thimg that you do the way that you want him to do it cuz youll have paid your dues and made it to that next level. Until then tho......stfu about warranty policies of somebodys shop.
In short,,,,,NEVER rub another mans rhubarb.
Sounds like you have an issue with other people having opinions. Life might be hard for you to cope with. I hope you at least found some relief in stating your own opinion. @@idahogreen2885
I've seen a few shorts of Dave's channel.... This is the first full video I have watched.... Dave is very matter of fact and borderline rude!
But, he gets to be like that... He is the MAN when it comes to engine's and I love how he doesn't sugar coat anything! Really like this guy!!!
It's refreshing to see an honest shop owner that provides good advice at a time where money is tight. If the gentleman was wise he would keep the truck rather than sell it. Todays trucks are pretty much junk being bogged down with emissions and technology. Hopefully you can convince him otherwise. Older is simpler and more dependable.
I have 2 5.9 cummins with the coolant bypasses installed. Both trucks pull equipment all throughout the sierra overpasses in 100 degree weather with a/c running. Pulling a 6% grade I've never seen the coolant temp over 200. Prior to the bypass it would constantly get very hot and would need to get out of the throttle to let cool. So first hand experience they 100% work very well.
he is ever so fortunate to have you on the job!!
Here in Australia we had Holden V8 motors. Over the years, as an engine reconditioner I encountered a lot of cases where these motors struggled to pick up oil (even after an oil change). The answer to this problem is to NOT fill the oil filter with oil. The pump has to SUCK oil and with air in the pump it has to try and PUSH the oil out of the oil filter before any flow takes place. I know mechanics are set in their ways but this WORKS. Assuming no other problems exist like you had with your Cummins another trick is to (with a sealed motor) introduce a slight pressure in through the oil filler with an air hose. If there are no faults in your rebuild you will pick up pressure immediately. At 150 rpm cranking it’s not ideal for the pump to perform. Careful not to pressurise the system and blow out a seal! This way you don’t have to crank your motor for 5 minutes hoping for pressure, if it doesn’t pick up within 5 to 10 seconds you have a mechanical issue.
I rebuilt all of my Rover and Land Rover V8's and that engine will just never suck oil on a dry rebuild, you have to pack the pump gears with Vaseline or some other petroleum jelly ( as it will dissolve into the oil, nothing else will do) and that guarantees oil pressure on cranking. As I always cranked the engine with the plugs out to get oil pressure before putting the plugs in and connected up. They started and ran perfectly on the button thereafter.
It’s good that you’re doing videos like this, because it shows people how involved and technical the job really is. It’s not just pushing buttons to fix cars, and the customer rarely sees how much physical effort and technical knowledge is required for this kind of work.
Excellent video!!! This engine was actually saved from much worse damage.. It is a good thing the client asked for A Simulated test, before running this vehicle... Good job guys!!!
Thank you very much!
Love the recorded calls as a service advisor it's pretty epic to see how you guys handle these discoveries. I think our job as advisors can be so much easier if we spend the extra time up front during intake fact finding and finding the relevant information through the noise. 👨🏽🔧👨🏽🔧
We agree!
Uk 🇬🇧 england comment I love watching this channel. When it moves to discovery, I will definitely be getting the membership to continue watching. Keep up the good work guys it's really entertaining 😊
Awesome! Thank you!
Love watching you guys work through a problem. The analogy of being a surgeon was great, I don't know the first thing about a motor and I sure to hell done want to try and rebuild one. If get an expert to do it.
I respect people who have the confidence to try DIY on their cars and give it a go, but motor rebuilds is for the professionals, not only because they have the know how but also they have the machines to test the engine for problems that we mere mortals don’t have. I hope the the machine shop who attempted a rebuild on this engine are watching this video, absolute conmen…
Honey wake up. A new Dave’s video just dropped!
😂
Please post an update to this one, thanks. Keep up the great content. 👍
I think if you ignore or skip past most of the theatrics, there was some genuinely good information to be had here. It felt like a TV show rather than an informative video.
Good ol fashion honesty, common sense, and ability all at the same mechanic shop. Great job!!!
It’s Friday again!!! Let’s see what is going on in the shop señor Dave doing the honor to narrate this video…I’m sure this will be a great episode for the Tv show whenever it will be on Tv 📺 Saludos!!!👋😃👋
Sure, appreciate your comments! You sound like the kind of person who is wonderful to hang out with👍
@@DavesAutoCenterCenterville Gracias!!!🙏 thank you for your kind words I’m going to need those tomorrow at H& R doing my taxes 😝 Y’all have a great weekend!!! Saludos!!!👋😃👋
This is the best engine channel on you tube
This shop is a BEAST. It would be my first stop even though I am aways from them.

Only one way to learn and he seems like a nice young guy. I hope it doesn’t deter him from trying this again. Now he knows who to go to and get a better start.
Never be afraid to fail because you’ll never succeed if you never take chances.
