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!
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.
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!
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?
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.
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 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!
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.
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!
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
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
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.
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.
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.
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.
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.
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😂
At my dealership it is R/R intake time plus 2.0 for four cylinder and 3.0 for 6 cylinder and 99% of customers decline this service. I have seen intake ports 60% clogged with EGR and PCV build up and still after photographic proof the customer decline.
I get why people decline, big money for something they don't see. But 3 hrs to blast out 6 intake ports that take about 5-10 min each? I get the R+R time, but an additional 3 hrs at how much an hr?
@@DeloreanGuy2 that is what technicians in large dealerships don't know. Tech's rarely see the money side. and like I said it is a low volume seller. I have done 10,000 sets of warranty injectors and just tried to get the added time to walnut blast the intake ports, NOPE, If it's not free it is not for them.
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 ???
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.
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?
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
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.
@@lynxstarautomotive208 just curious how the chemical cleaning would damage exhaust valves ? Aside from dislodging carbon and possible bending a valve but at that point piston rings , bore finish and valves are all at risk ?
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

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.

Repair videos and shop stuff for sure, thanks for your videos and keep up the good work.
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
I started using Amsoil PI additive every 5000 miles to try and prevent this and keep clean.

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.
Yep nothing like a Toyota. Use shell gas and Techron occasionally. It works and keeps things clean.
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!
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.
I like all of your videos so anything you put out is fine by me. Someone can always learn something on any procedure.
Love a shop that is all about quality
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.

Performed walnut blasting service on several Honda fit's with GDI very common for cold start misfires when cold, just a heads up.
Just saw this not long ago on rainman Ray's channel too. You guys were way cleaner lol. Really amazing how well it works.

More of all related content. It's all in some way applicable, enriching, informative, and entertaining to most people.
I would be interested in both concepts of videos. One where the mechanics are filmed, and diagnostics. Thanks as always for the useful info
Thanks for educating us on modern maintenance. I had no idea of that process or GDI in general
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 😊
This is why i went back to port injected car. And adding liquimoly valveclean once in a while.

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
You guys should make a diagnostic video of a misfire(s) related to this! Always wondered what they look like on the scope
You sold me on it. The benefits are nice. I will share with my boss.
