What is walnut shell blasting and is it safe for my engine?

Yes! It’s a non-abrasive cleaning method using crushed walnut shells to safely remove carbon deposits from intake valves.

How often should walnut blasting be done?

Typically every 80,000–100,000 km depending on the engine type and driving habits.

Does walnut blasting improve fuel economy?

Absolutely. It restores proper air/fuel flow, improving fuel efficiency, power, and throttle response.

How long does the service take?

Most walnut blasting services can be completed within 2–3 hours.

Is walnut blasting better than chemical cleaners?

Yes. Chemical cleaners can't reach the intake valves in direct-injection engines. Walnut blasting is the most effective method.

  I have had repeated problems with the DEF system . I went looking for a service center where I could have a conversation about my vehicle with an informed person at the front desk. I found it at Dales.

  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.

It’s a specialized cleaning of intake valves/ports using crushed walnut media to remove carbon on direct-injection engines without damaging metal surfaces.

2) How often should I do it?
Most BMW DI engines benefit around 80k–120k km. Tuned cars, short-trip driving, or heavy city use may need it sooner.

3) What are the benefits I’ll notice?
Smoother idle, better throttle response, restored power, improved fuel economy, and fewer misfires.

4) Is it safe for my engine?
Yes—done correctly with ports sealed and borescoped, walnut media won’t harm metal. We document before/after photos for peace of mind.

5) Do EVs need walnut blasting?
No—EVs have no intake valves. We still service EV brakes, tires, suspension, alignments, and inspections with EV-safe procedures.
