I waited a year to see if there would be problems with a timing belt kit install on a Sequoia. There are none and the Truck runs great, that s why I gave 5 Stars. I would go back.

Excellent service. They’re very professional and would always recommend them, the diagnosis was accurate and fast. It was a transmission failure therefore I needed a replacement, which they delivered at a timely manner, despite the amount of work involved. Great work and quality.

A+++. I would highly recommend getting your vehicle serviced at Dale’s. Jameson and his team run an honest shop with fair prices, and the tech’s will treat your car as if it was their own. I’ve taken numerous vehicles to Dale’s over the years and have never had a poor experience.

Yesterday morning as I prepared to leave my home, my car sputtered to start. I drove to Dale's and thankfully my car could get booked in to check the source of the problem. Within 15 minutes, I was called to advise me that I needed a new battery. Within two hours my car was ready for pickup. I have been a customer for many years and I have always received friendly, informed and timely service.

I had such a positive experience with Dil and the entire team at Dale’s Auto Service. From the moment I walked in, everyone was incredibly friendly, welcoming, and professional. They took the time to listen to my concerns, answer all of my questions, and explain everything in a way that was easy to understand without ever making me feel rushed or uncomfortable. As a woman, going into a mechanical or automotive repair facility can sometimes feel intimidating, especially if you don’t have a lot of mechanical knowledge. Unfortunately, it can be difficult to know whether you are being given all of the information or being treated fairly. My experience at Dale’s Auto Service was completely different. I genuinely felt respected, comfortable, and included throughout the entire process. Dil was especially helpful and made the whole experience incredibly easy. He was patient with all of my questions and made sure I understood what was happening with my vehicle, what was recommended, and why. There was never any pressure, confusing terminology, or feeling like I was being talked down to. Everything was explained professionally and clearly, which gave me a lot of confidence in the work being done. Dale’s Auto Service really does feel like a women-friendly automotive facility. The staff creates an environment where you can comfortably ask questions and actually receive thoughtful, honest answers. They make something that can normally be stressful feel straightforward and manageable. I also really appreciated how organized and professional the entire shop was. The communication was excellent, the customer service was friendly, and I felt like my vehicle was being taken care of by people who genuinely care about doing the job properly.

Professional staff, friendly. Quote for work was spot on. No surprises, and car(STI) all good so far. Will definitely return for future maintenance and repair.

Subaru Walnut Shell Blasting Near You

Why Subaru Walnut Shell Blasting?

Direct-injection Subaru engines (WRX, Forester, Crosstrek, BRZ/GR86* DI trims, etc.) build carbon on intake valves over time. Our Walnut Shell Blasting safely removes these deposits, restores smooth idle, power, and fuel efficiency—and helps prevent misfires and check-engine lights.

  • Rough idle, hesitation, or loss of power

  • Poor fuel economy, sluggish acceleration

  • Misfires or check-engine light codes for air/fuel issues

  • Intake valve images show heavy carbon during inspection

What We Service

While this page focuses on Subaru, our experienced mechanics near you perform intake valve cleaning on all makes and models that suffer DI carbon build-up (VW/Audi, BMW/MINI, Kia/Hyundai, etc.). If you daily a Subaru and weekend a European—we’ve got both covered.

How Walnut Shell Blasting Works (The Dale’s Difference)

  1. Inspection & Diagnostic: Borescope the intake valves, check fault codes, baseline health.
  2. Intake System Prep: Safely isolate the intake, set cylinders at closed-valve positions.
  3. Media Blasting: Precision-blast crushed walnut shells to lift carbon without harming metal.
  4. Vacuum Recovery: High-flow extraction removes media and deposits as we clean.
  5. Reassembly & Test: New gaskets as needed, clear codes, test drive, post-scope photos.

Benefits you’ll feel: smoother idle, crisper throttle, restored power, and better MPG.

Why is Walnut Shell Blasting Necessary for DIT Engines?

In direct injection engines, fuel is sprayed directly into the combustion chamber rather than over the intake valves.

As a result, the intake valves are not regularly cleaned by fuel, leading to the accumulation of carbon deposits over time.

This carbon buildup can restrict airflow, disrupt fuel-air mixture, and negatively impact engine performance.
