Direct injection is starting to make its way in the the independent shops. What are you all doing to remove the carbon build up in the intake chamber? This is something that I do not have much knowledge about but for see it becoming a large service at 50-100k.

I rotate engine to make sure valves are closed, and soak in carb cleaner, seafoam etc.. then vacuum it out, scrape any big chunks off valves, repeat, vacuum, and blow out port with an air hose then on to the next valve. Involved process.

 

A blasting media would spead it up a lot but how would you control the mess? I'd also be feaful that a tech may get media in an open valve (just thinking worst case scenario).

I have a factory BMW media blaster for BMW/MINI with specific attachments. Whatever u get make sure it is a pressurized media blaster. The cheap ones from harbor freight or wherever DO NOT WORK. This will be an investment in tooling and media so you have to charge accordingly!

I've heard really good things about the Mopar top end cleaner.

It is a aerosol foam spray that does the same job as carb cleaner, seafoam etc, minus the liquid going into the cylinders.

As you spray it in, the foam expands to fill the whole plenum then dissolves all the carbon.

Apparently it's the same formula/MSDS as Wynn top end cleaner, except it's in foam form, where Wynn's is a liquid.

Are there any proven gas treatments to help prevent this issue? Are catch cans helping?

I run a catch can on my personal truck, 2010 Sierra 5.3L. Those gen 4 GM engines are known oil consumers, the AFM and PCV systems get oil into the intake.

Any catch can will catch some oil, but ALL of the cheap ones you find on eBay etc will catch less then 20% of the oil that passes through unfortunately.

Most of the cheap catch cans (and some expensive ones) are basically an empty beer can with 2 tubes sticking out, the good ones have way more technology involved.

A good (re: expensive) catch can will catch upwards of 95% of the oil that passes through by the use of multiple chambers, screens and valves.

If you're not paying $100+ for your catch can, it's probably junk. And yes, I did a lot of research before I bought mine.

 

Something to think about:

Every heavy duty semi truck on the road has some form of oil separator in the crankcase ventilation system. Why don't passenger cars?

Same. Get a legit walnut blaster and save yourself a LOT of headache.

 

Our techs would spend HOURS manually scraping down intakes and valves with the MOPAR top engine cleaner. The walnut blaster + vacuum has dropped this down to a 1hr process.

 

We are going to start seeing a lot more direct injection problems in the coming months/years. This is going to be a must-have tool.

I would suggest against the HF blaster. We perform carbon blasting regularly and the pressure pot type of blasters work 10x better than the Rigged up HF version. This has been my experience and perform several blasting jobs monthly so take it for what you will.

      The Technician Shortage Is Our Fault, And It's Time We Own It
      Nearly every day, I hear shop owners complain: "There's a technician shortage. We can't find qualified people. There's no one out there." If that's true, then who's to blame?
      The industry? The schools? The government? I don't know how you feel, but who promised us an endless supply of qualified technicians?
      Another common complaint is that young people do not want to work in the trades. Well, if that were true, then why are other trades such as HVAC, electrical, and plumbing growing? What are they doing that the automotive industry is not? 
      Here's the reality we need to face: We do have a problem, but we shouldn't look for someone or any entity to rescue us. Not the government. Not the trade schools. Not the recruiting companies. No one owes us a workforce. If we want great people in our industry, it's up to us. At some point, we need to own up to the truth: Building a pipeline of qualified technicians is our responsibility.
      In this blog article, I will break down the key reasons we are in this situation today and what we, as an industry, can do to solve the technician shortage. Are you ready to look in the mirror?
      Have We Pushed Technicians Away?
      Let's take a look at flat-rate pay. True flat rate, which pays a technician only for the hours they produce, is a controversial pay plan that emphasizes high production levels and creates a competitive work environment that, if not properly controlled, can lead to increased mistakes and a decline in morale and team spirit. Additionally, the stress and physical demands placed on technicians as they age are not favorable to long-term employee retention. What do we do with technicians as they grow older into their fifties and begin to slow down? 
      I have heard all the arguments and pros and cons of flat-rate pay, and I am not going to judge any pay plan. Let the facts speak for themselves. True flat rate has changed in most areas around the country and has evolved into a pay plan that gives technicians some pay guarantee.
      Many shop owners have learned that team morale, along with the opportunity to earn income, is important to technicians and to the company's long-term success. But let me ask you: how many technicians have left or been pushed out over the years because of the old flat-rate pay system?
      Another issue is the workplace environment. I remember being grateful to be hired as a young technician at a local repair shop. While very thankful, the work environment was not ideal. The shop owner kept the bay doors open year-round (I am from New York) unless it rained or snowed. He felt that if the bay doors were closed, customers might think we were closed for business. We had no heat and no hot water. Many of the jobs were done outside, year-round,  in all types of weather. The starting pay was minimum wage, with no benefits, sick days, or vacation pay. 
      Now, again, I need to point out that I was truly grateful for the opportunity this shop owner gave me. I learned a lot working there, and the experience was pivotal in my career. But looking back, I wonder how many people were discouraged by these working conditions?
      While the physical demands of the repair workplace are daunting, perhaps even more critical is the culture. Too many of my generation shop owners preached the mindset of "my way or the highway." We were the business owners, after all. We started our companies, took all the risks, and provided jobs. Why shouldn't we be the ones to set the ground rules our way?   
      Many of us found over the years that the "my way or the highway" mentality was a sure way to isolate employees and make them more likely to look over the fence for greener grass. In other words, it led many technicians to seek employment elsewhere, where they felt they could be appreciated and recognized for their hard work. The issue, however, was that there wasn't much green grass around. Disappointment after disappointment, bouncing from repair to repair shop, eventually led to despair. So, I ask you: were workplace conditions a contributing factor in today's technician shortage?
      Another factor that we are all well aware of is the complexity of the modern automobile. When I started, the work was mostly physical, and you were required to master essentially three vehicle models: General Motors, Ford, and Chrysler. Let's fast-forward to today. The evolution of automotive technology, along with the extensive training and tools required, has outpaced the typical technician's pay compensation, with no clear career path. Again, leading to frustration and insecurity about the future.
      Here is the bottom line: people don't leave their job; they leave their experience. We must do a better job. 
      The News Isn't all Bad; Your Next Steps to Fix the Technician Shortage
      To fix the technician shortage, it will take a combined effort from everyone in the automotive industry, particularly automotive shop owners. Shop owners are in the perfect position to make the greatest impact, not only on their businesses but also on the future automotive workforce.
      First, shop owners must become better leaders and understand that their ultimate success is directly dependent on the people they assemble around them. Any shop owner who mistakenly believes they can build an empire solely on their abilities is destined for serious disappointment. Business owners who think like this will eventually plateau. Without the collective contributions from a team of qualified people, your business will stall; it will not continue to grow.
      Create a workplace that attracts top talent: a clean, professional, well-equipped facility designed to support productivity, teamwork, and a career, not just a job. Build a great reputation in your community by getting involved locally. Become the auto repair shop that people take notice of as "the" place to work.
      Next, shop owners must become more financially knowledgeable. Knowing your numbers and what you need to achieve for a strong bottom-line profit is essential to paying technicians the money they need and deserve. Profit will also allow you to compete with other trade industries by providing a benefits package that has real take-home value and security.
      When it comes to culture, this is where the rubber hits the road. People crave recognition, praise, and a sense of purpose. Despite what you hear, people are not just money-motivated. Once people feel secure in their financial situation, retaining and motivating technicians can only be achieved by connecting with them on an emotional level. You cannot show enough appreciation. Give out praise for a job well done as if your business depended on it, because it does.
      As technicians age, we need to have a place for them. Expecting a 58-year-old to perform like a 35-year-old is unrealistic. We need to be more focused on career pathing. Provide training, skill development, and coaching to develop leaders and mentors within our older workforce. While their bodies may have slowed, the knowledge they have gained is priceless. 
      Our future is dependent on young people entering our industry. We need to give more young people opportunities. Every shop owner across the country should consider hiring an apprentice, then build an apprentice training plan and career path for them. If every shop did this, we could solve the technician shortage within five years. Get involved with the trade schools and high schools in your area. Look into the NAPA Apprenticeship Program. Don't sit on your hands with this one. Do it today.
      Lastly, don't get left behind. Commit to ongoing training for all your employees. Keep up to date with tools and equipment tailored to your business model. Don't try to be all things to all people and all vehicles. Identify your core profile customer and the vehicles they drive, and become an expert on those vehicles and the services you offer.

      One of my goals this year is to "Brand" the shop and really push my marketing! One of the local attorneys in town is using a billboard and he said it's the best move he's made for marketing.
       
      My shop is In a small town of about 25k population. There is about 5 large "poster" boards around town, Once you pull into town about 1 mile before our shop there's a billboard, Our shop is on one of the main streets in town behind a gas station(hidden) The land lord will not let me put up a big sign on the road. So the alternative, is billboards??
       
      My question is, has anyone ever used one?? If so, do they work?
       
      It's pretty expensive, 800 a month.

      A customer that is a Realtor mentioned to me that he is having success using a program called https://calltools.com/ for outbound call marketing.
      I was thinking about doing something like this for this Spring season, has anyone here used an outbound call system of marketing? I have a list of over 80,000 customers and I was thinking it would be a good time to see what results it may bring.

      There is an ever increasing percentage of women that are decision makers in where the family funster goes for repairs. The Automotive Aftermarket Industry Association discovered in a recent study, almost 90% of women are now involved in the decision process for their vehicle’s repair and maintenance, 68% of them take the vehicle to the shop themselves, 45% are solely responsible for their auto repair and service decisions.  That is amazing.  Do you have 60% or 70% female clients? What do you do to adapt to this changing dynamic?

      This is a great survey taken from shop owners by Ratchet and Wrench magazine.  Amazingly, 17% of shops surveyed don't harness the power of social media.  By a large margin, shops prefer Facebook.
