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.

Mazda Walnut Shell Blasting in Surrey & Langley, BC

Is your Mazda down on power, idling rough, or throwing fuel-trim codes? Direct-injection engines (like Mazda’s Skyactiv-G) can build carbon on intake valves—hurting performance and efficiency.

Dale’s Auto Service offers professional Walnut Shell Blasting to safely remove carbon deposits, restore throttle response, and help your Mazda run like new.

Why Dale’s Auto Service?

  • Complete auto repair and service for all makes and models

  • Transparent quotes, photos/video inspections, and fast turnaround

What Is Walnut Shell Blasting?

Walnut shell blasting uses finely crushed walnut media to gently clean intake valves and ports without damaging aluminum heads or coatings. It’s the proven, manufacturer-approved method for direct-injection carbon removal.

Benefits:

  • Restores horsepower & smooth idle

  • Improves fuel economy & throttle response

  • Reduces misfires, cold-start stumble & intake valve sticking

  • Supports longer engine life when paired with quality maintenance

Mazda Models We Service

Our Mazda Walnut Blasting Process

  1. Intake Inspection & Diagnostics – Confirm carbon buildup with borescope and scan data.
  2. Intake Manifold Removal – New gaskets and OE-level procedures.
  3. Valve Positioning & Masking – Each cylinder sealed and staged for cleaning.
  4. Walnut Shell Blasting – Media introduced under controlled vacuum for a spotless finish.
  5. Reassembly & Adaptations – Torque-to-spec, clear codes, verify trims & road test.
  6. Preventive Guidance – PCV checks, quality fuel, oil service intervals, and drive-cycle tips.

Ideal Service Intervals

For most Mazdas, we recommend inspection around 80,000–120,000 km (earlier if tuned, short-tripped, or showing symptoms).

Walnut Shell Blasting FAQ

1) What symptoms mean my Mazda needs walnut blasting?
Rough idle, sluggish acceleration, reduced fuel economy, random misfires (esp. cold), intake valve deposit codes, and audible intake “chuffing.”

2) Is walnut blasting safe for Skyactiv-G engines?
Yes. With ports sealed, proper valve positioning, controlled media flow, and continuous vacuum, it’s safe and the industry-preferred DI method.

3) How long does the service take?
Most jobs are same day depending on model, mileage, and add-on services.

4) Will a fuel additive fix carbon on intake valves?
Not on DI engines—fuel doesn’t wash intake valves. Physical cleaning (walnut blasting) is the reliable solution.

5) How can I slow carbon buildup after blasting?
Use top-tier fuel, keep up with oil services, ensure the PCV system is healthy, and take periodic highway drives to reach full operating temps.

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.
