The One Maintenance Service Every Auto Repair Shop Should Be Doing!

[@loveandbaconbrian1901]

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!

[@lescarlock4405]

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!

You take better care of your motor than i take of myself.

[@georgeanddaddecker7563]

Walnut blasting is the most effective. Leave combustion chambers looking like new.

[@billmonroe8826]

It seems with this problem the manufacturers should figure out something better because aspirated engines don't carbon up.

[@jdtractorman7445]

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

[@lynxstarautomotive208]

@@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.

[@georgeanddaddecker7563]

@@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.

[@mshaw290808mi]

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.

[@kauaiboy111]

Toyotas have port injectors to help reduce this type of carbon. Thanks for this video! ❤

[@user-pj5ff6xw4x]

Toyota also has GDI engines in a lot of their models.

[@simplygregsterev]

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

[@rjmari]

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?

[@simplygregsterev]

@@rjmari needs to go through intake. There are a couple options now. We use CRC GDI cleaner and have had really good results.

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.

[@jrkovar]

More of all related content. It's all in some way applicable, enriching, informative, and entertaining to most people.

[@BeingInTheMessiah]

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.

[@garyhennessey3621]

Yep nothing like a Toyota. Use shell gas and Techron occasionally. It works and keeps things clean.

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.

[@friedrichpsp]

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.

Yes but Toyota has ds4 which is PORT and GDI so that is not needed I think. Thanks for the video it was very informative.

[@jeremystone6613]

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?

[@mechanknuckle]

How do you feel about chemical blasting into throttle body every oil change? Would that helo keep the carbon from building up?

[@theroyaltyautoservice]

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.

[@lynxstarautomotive208]

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.

Definitely something that SHOULD be done, but realistically most people who have a GDI (Hyundai/Kia) engine can't afford maintenance. It seems everyone wants a toyota camry or honda civic that they never maintain and runs forever... Maybe your environment and customers work with you better, but most people around me don't want any service until its too late and something needs fix or a new engine/transmission. Perfect results overall, wish more people would do it. Direct injection is great, until its not! Lets see more content, I want to know more about how you run your business, what your approach to solving problems are, as well general repairs and maybe even "customer complaint" videos like ConceptIII is doing.
