Why your European car needs a walnut blast

Automakers like Mercedes-Benz, Volvo, Mini, Volkswagen, Jaguar, Audi, and Porsche prefer direct injection engines because they increase fuel mileage and engine power. Carbon is a by-product of releasing fuel into the combustion chamber, the basic function that allows your car to run. Walnut blasting breaks up the carbon that collects in the intake manifolds, which is a common occurrence with direct injection engines.

Keeping your vehicle’s intake valves clear of carbon build up is essential to its overall performance. Similar to how people need healthy lungs and clean air to breathe, cars must have engines and intake valves free of residue for normal combustion. When carbon builds up inside the manifold, we use a walnut blasting tool to blow crushed walnut shells through the engine with an air compressor. It may sound nuts, but trust us; it keeps your car performing at its peak.

Signs of carbon build-up

When carbon coats and collects inside the engine, it restricts combustion and alters the operation and efficiency of your vehicle. An illuminated check engine light is a good sign your intake valves need some TLC. However, there are other warning signs that point to carbonization, including:

  • Loss of horsepower
  • Engine misfire
  • Extended start time
  • Rough idle
  • Trouble accelerating
  • Fewer miles per gallon

You may not notice a decrease in performance if it happened gradually over time. That’s why Performance Auto Specialists recommends walnut media blasting as routine maintenance every 30,000 miles.

Benefits of walnut blasting

Carbon is hard and tough when it forms. Manually, it would require a lot of elbow grease to clean it from the intake valves. A walnut blaster works like a sand blaster, but it’s gentle enough to maintain the integrity and functionality of the engine parts. It also spares us from stripping the engine and cleaning it by hand, a job that costs a lot of time and money.

The tool blasts walnut shell granules at the carbon build up, while an adaptor vacuums the shells and residue out of the valves. This is a much more efficient way to clean inside the engine. Regular cleanings also prevent wear and extend the life of your engine, saving you money on major repairs in the long run.

Once your vehicle’s engine is free of carbonized clogs, it will regain the power and performance you’re familiar with. Improvements you can expect after walnut blasting the intake valves include:

  • Better throttle response
  • Smooth engine idle
  • Improved fuel economy
  • Increased horsepower
  • Other benefits of a clean engine

Walnut blasting is a common and dealer-recommended option to keep your car in tiptop shape. As soon as you experience a dip in performance, get to the shop for a thorough examination.
