To answer your question I’d say a video on anything you do which has a special twist to it from most shops - which so far seems like everything! What a clean, professional operation… And your kid’s night is truly inspiring. Thanks for the great content and for raising the bar!
Just you tube surfing, and came across this channel! I do all my own preventive maintenance, on my 16 f150 3.5 eco! I just did my second walnut blasting, at 88000 miles! First time at 68000, and thought nice day to just take a look at the intakes! They weren’t really too bad, like they were the first time, but it sure didn’t hurt to clean them again! I do oil changes at 3000 miles! Oil life shows usually 53-57 percent Life left! When I first got the truck, it had 33000 on it! I trusted that oil life! Until I started writing down mileage! Found out I was putting on 7500-10000 on that oil! For an old man,(71) it’s not real easy to climb around that motor, but at least I know what’s done! I’ve changed all drivetrain fluids, coolant, brake fluid, I rotate the tires my self! Oh, and I do have oil catch cans on it also! Thanks for showing before and after pics of those intakes! Great video!
The problem is with direct injection vs. port injection. Port injected motors don't have these issues because it puts fuel at the back of the intake valve, thus keeping it clean. Direct injection is directly in the cylinder. With no gas hitting the back of the intake valve on DI motors, you have bad carbon buildup. @@billmonroe8826
@@billmonroe8826Rhey have started to play with the timing tables, and have managed to help cut down on the carbon build up a ton. Mercedes Benz doesn’t have this issue. You will find some of their engines with over 100k and minimal build up.
@@billmonroe8826 They did, the solution is to have both gdi and port fuel injection. This way the port injection cleans the intake ports when it is running at certain times. This is why port injection engines never had this issue. The problem is only certain models have this combo, usually top tier models, as it is more expensive to manufacture.
I don't think you want to blast the chamber just the intake pre valve and the tops of the valve. Keep the piston at tdc and the other intakes sealed .The chamber cleaning- an Italian tune up
This issue is one of the main reasons I bought a RAV4, Toyota added GDI but left port injection so the valves would get sprayed with gasoline keeping them clean.
yes that will disrupt laminar swirl flow (the engineered flow pattern, that you mentintion as turbulence or disturbance as there is swirl effect desired but it is not true disturbance. Better stated it is "laminal swirl". Look up and or work with aircraft airflow design to better understand laminar flow and then the same with laminar swirl flow in combustion. Also a VERY IMPORTANT issue that all to many customers in both residential and commercial HVAC do not grasp the importance in proper cooling and heating. ALSO Glad you mention that you blow all residue out after the procedure. I know many that do not. Bad practice when they do not even though the walnut burns off. Again I cant say or stress enough to keep up the GREAT video and education!!! Having been out of the Auto Service since 1993 yet still try and keep up to some extent would love to see diagnostics more than the grunt work. LOL If I were to EVER get back into auto service I most deffinatly WOULD NOT do the grunt work ROFL. You mentioned how engineers have a hard job and they do yet I have no desire to work on what the engineer ROFL!!!
Im a Euro repair shop. The amount of EA888s we get in with misfires where other shops have fired the cannon at are insane. All they need is a cleaning and in some cases a new intake manifold. There are some good products around GDI intake spray that actually work “okay” as a maintenance solution after a proper cleaning has been done. Stick with good quality oil, low saps and change it regularly
What intake sprays do you recommend for maintenance after walnut blasting? And what is your recommended delivery of the spray? Can it be sprayed down the spark plug holes? Or does it need to go through the actual intake?
Probably one of the most underrated shops on social media right now! Love the content you guys put out and the shop always seems well ran and well put together! Fantastic!
Your videos are excellent ! Whatever you want to shoot, we want to see. Diagnostics, repairs in progress, your "thinking process" when trying to figure out particularly difficult to determine problems, and yes, tips for shops to consider that will improve their customer satisfaction and their profits. Will love seeing it all.
We've got a new tool that should be here in the next 6 weeks to do some testing on GDI injectors. I'm excited to play with it and will definitely make a video using it.
FOr future videos I think your viewers would enjoy, as well as your employees, kind of a "this is how the shop operates, but it wasn't always this easy, this is how I got into automotive repair" Include personal development alongside just the nitty gritty. People need to believe they can achieve great results in their career like you guys.
I like any and all vids you produce. It's good to see repairs of all kinds done. Very helpful to get other folks knowledge out there. Thx for doing this!!!
have you guys ever looked into some of the Hydrogen cleaning machines like Carbontek etc. They do an amazing job and require no teardown just a hose into the air intake hose. I dont work for them or anything but have used and they are amazing. Some OEMS are using them now and approved for use by those OEMS.
Love your videos. I think more repairs videos would be great. But your informative and diagnostic videos are extremely insightful. Keep it up, thank you!
Mazda also recommends this, not sure of the mileage or if you guys have seen many 2.5 Turbo GDI on CX-5’s to know when to consider this. In fact I don’t think I’ve seen a Mazda much less a CX-5 in your videos. Absolutely needed service.
For those that don't know, Autool makes very high quality automotive equipment at a value price! Their smoke machine for example... The Autool SDT 206 is amazingly build from the inside out with quality parts and does an amazing job in finding leak issues fast and reliably! Worth every penny!
A few years ago I worked with a company that was testing an air filter oil catch system in line for the pcv it worked quite well I haven't seen it production yet
What I like to see videos on the step by step process on moonroofs , seat tracks tear down, lift gate motors and sliding door motors and replacement of evaporators. There not many videos out there on steps and tips for this.
I have a small shop and I work on everything so very interested in all your job that you do and you’re specially stuff I subscribe and I’ll keep you in. Keep watching. 1:00
Okay, I've never seen that before thats NUTS! HAAAA! no but seriously never seen that before that before and after is night and day! incredible! I would be jumping for joy if I were the owner of that GDI, I hope you sent them this video!
I just upload a video explaining this same issue. The carbon build up is really harsh and create alot of misfires due to lost of compression issues. Great video as usual Mr Sherwood. The Autool HTS work really great. Thanks for sharing.
An oil catch can does help capture some of the oil mist from the pvc system that causes this issue. Not perfect but you would be surprised how much oil is in the catch can between oil changes.
I love your videos, Sheldon, but I'm old and need to get me a Clayton. Looks like you just toss him a banana, and he is all happy happy and good to go. Lol
From the looks of the comments, any of the potential topics mentioned would be well received. Being on the diagnostics/electrical side of things, some ADAS episodes could be interesting. Thanks, Al H.
Boy, I have to write that I’m sure glad I don’t own a GDI engine! I’m very happy with my fuel injection on my ‘12 Chrysler Pentastar V6.On the highway I regularly enjoy 30 miles per gallon with my 200 Touring convertible.
I never had luck with the vacuum set up need to be able see what im doing i tape the engine bay with plastic film put a face shield and gloves and go to town😂
Do you recommend the chemical clean as a preventative maintenance once a year to keep build up from happening ? I understand mechanical cleaning is best and I would have concerns of using chemicals in the intake ! What’s your thoughts ???
Make repair videos, with explanations of what the customer stated,and how the problem was diagnosed, it dont have to be full diag, just clips of the process with a quick overview of the diag., well atleast that's what I would like to see
I’m curious about your comment “the technician gets paid well”. Shops in Australia work on an hourly rate system-eg 8 hours a day with penalty rates added for overtime hours. I’ve always struggled to understand how it works in the States. Does the tech get paid by the hours charged out per job to the customer thus incentivising more efficient work practices? What happens with comebacks and quality if that is the case? How do you pay for road testing and diag time and research?
About what price to do a Buick 2.5 4 cylinder with no turbo 2020 how often should be done how far are you from Jacksonville Florida Thans for all the great info you post
What happens if you don’t turn the motor over to close the valves and use this Walnut blaster ? Or if one valve was slightly open ? Just curious if someone did this and what happened
Maybe if that was done from oil change number 1. It may work better on some engines and not on others because of the intake manifold designs. That's what's so difficult with this problem. So many different engine designs with the same problem.
You need to be very careful with the chemical cleaners. VW does not approve this method, and I have seen many engines damage exhaust valves thanks to the chemical process. Just good for thought.

You take better care of your motor than i take of myself.
You should oil your “!” Key… I think it gets excessive wear
Yes, I would like to watch you when fixing cars , anything is interesting, with all the details w/o skipping steps and explaining all the way.
Walnut blasting is the most effective. Leave combustion chambers looking like new.
It seems with this problem the manufacturers should figure out something better because aspirated engines don't carbon up.

We have had very good success with the BG Platinum Service. An often overlooked service and usually due to lack of educating the client.
That’s what I was inquiring about using a chemical clean as a preventative maintenance option

Probably one of the most underrated shops on social media right now! Love the content you guys put out and the shop always seems well ran and well put together! Fantastic!
I started using Amsoil PI additive every 5000 miles to try and prevent this and keep clean.
Yep nothing like a Toyota. Use shell gas and Techron occasionally. It works and keeps things clean.
Fascinating info I never heard about the walnut cleaning.

I like all of your videos so anything you put out is fine by me. Someone can always learn something on any procedure.
I do use CRC intake/turbo cleaner. It works great. Do it to my acura once a year and it runs great all the way through.
Really like videos on diagnosis of running issues/ electrical issues, etc. How to's on becoming a better diagnostic technician.
Love the channel!!
Gdi injectors diagnostic is what i would like to see more of.
Scope and non scope techniques if possible
We've got a new tool that should be here in the next 6 weeks to do some testing on GDI injectors. I'm excited to play with it and will definitely make a video using it.
Is it the ADDi? I ordered one couple days ago after I watched the demo on Super Mario's channel.

I would be interested in both concepts of videos. One where the mechanics are filmed, and diagnostics. Thanks as always for the useful info
Awesome that's how i do it.
Definitely makes the engine run like it's new.
On and i want to see more repair videos 😊
Just saw this not long ago on rainman Ray's channel too. You guys were way cleaner lol. Really amazing how well it works.
So, its basically $800.00 to $1,000.00 to do this! Thanks to a bunch of Engineers that can keep things simple!
They just need to make it through the warranty. And then they can explode.
More of all related content. It's all in some way applicable, enriching, informative, and entertaining to most people.
This is why i went back to port injected car. And adding liquimoly valveclean once in a while.
What vehicle?
@@atticstattici had opel insignia (buick regal) gdi 2018. Went back to Opel mokka (buick encore) 2013. Buicks are Opel in europe.
@@aciddiver1978
I bought a 2016 Chevy Trax because of that
I use seafaom gdi cleaner to clean my valves at home. Its worked great. love ur videos
I have a Hyundai Santa Fe with a 2.4 GDI engine I’ve had a catch can on it since the day I’ve owned it and it’s helped a lot
Thanks for educating us on modern maintenance. I had no idea of that process or GDI in general
I like the diagnostic videos the best. Thanks for sharing your experience and time.
You guys should make a diagnostic video of a misfire(s) related to this! Always wondered what they look like on the scope
Yes on repair videos and shop operations. Thanks.

You sold me on it. The benefits are nice. I will share with my boss.
This blew my mind a bit. That’s cool!
Id like to see both the troubleshooting and the repair.

What about a catch can? Mine has a metal honeycomb as a filter.
@@garyganser2451 that would be great option
I enjoy the diagnostic videos
would like to see both diagnostics and repair vids. I love the diag vids and perhaps keep most vids diag vs repair
Learned something new about gas thank you mate.

Glad my Venue is 1.6 NA with multi port.
would like to see diesel work also. repair videos would be great.
I heard now you can also dry ice clean valves, dying to see it in action.
I've checked on it. It's quite expensive to purchase the equipment. Hopefully the price will come down because, from what I've seen, it's awesome.
imagine the person who thought, hey i bet these walnut shells would work to clean those valves. That guy must live outside the box lol.
Media blasting has been a thing long before direct injection came into the picture.
I want to see this intake cleaning on an alfa Romeo stelvio. 2.0 L
I wanna see all of it 😅
If the problem is caused by oil vapors, would a catch can help prevent it?
What's the approximate charge for a four cylinder GDI engine? Thereabouts or a range? One similar to your video?
We charge labor to R & R intake plus .5 per cylinder to clean.
I’m curious about your comment “the technician gets paid well”. Shops in Australia work on an hourly rate system-eg 8 hours a day with penalty rates added for overtime hours.

That could be cleaned with chemicals. Induction service.
About what price to do a Buick 2.5 4 cylinder with no turbo 2020 how often should be done how far are you from Jacksonville Florida Thans for all the great info you post
That one is probably right around a little over $1000. We are only 30-40 minutes north of Jax. Let us know if you’d like to come by!
What happens if you don’t turn the motor over to close the valves and use this Walnut blaster ? Or if one valve was slightly open ?
Just curious if someone did this and what happened
That wouldn't be good. But you could probably suck out the walnut shells thru the spark plug hole.
Where was this in the CAFE equation?
I’ve seen dry ice being used I would think it’s more expensive
easy money like wheel alignment.
Outside of the labor time to r&r intake how much time are charging for the cleaning portion?
.5 per cylinder.
How do you feel about chemical blasting into throttle body every oil change? Would that helo keep the carbon from building up?
Maybe if that was done from oil change number 1. It may work better on some engines and not on others because of the intake manifold designs. That's what's so difficult with this problem. So many different engine designs with the same problem.
You need to be very careful with the chemical cleaners. VW does not approve this method, and I have seen many engines damage exhaust valves thanks to the chemical process.
