Automotive Walnut Blasting

Are you losing power and responsiveness? Does your engine misfire? Does your car feel more sluggish than usual? You may need an engine clean. Walnut blasting is an effective way to clean out your engine. Our automotive walnut blasting service at Foreign Affairs Motorwerks will keep your intake valves crystal clean.

How Does Walnut Blasting Work?

Over time, carbon deposits build up and begin to black your intake valves. Walnut blasting “shoots” a mixture of walnut shells and compressed air into your intake ports to clean them out. These crushed walnut shells are effective at cleaning at high speed. This process is like sandblasting, but also gentle enough to be safe for your engine. Walnut blasting is only used on cars with direct injection engines.

To access your intake ports, your mechanic will remove your intake manifold. This will expose the intake valves for cleaning. All engine cavities are sealed up with special tape before the walnut blasting starts. The mechanic will then blast out each valve while sucking up the excess walnuts. Here’s a closer look at how walnut blasting works.

Why Walnuts? Walnuts are a good medium for intake blasting. They’re abrasive enough to lift carbon off a surface but gentle enough not to damage your engine. It’s good news then that California’s central valley is home to over 4,500 walnut farmers.

Why You Need Walnut Blasting

Carbon is a by-product of engine combustion. Every time you accelerate, spark plugs ignite the gas. This process leads to small amounts of carbon developing in your intake valves. Carbon affects your engine’s combustion. More specifically, your operating temperature, sensor readings, and compression ratio. These all play a role in helping your engine to “breathe”. Carbon begins to choke your engine over time.

Our technicians at Foreign Affairs are able to correct all these side effects. Our state-of-the-art automotive walnut blasting machine will clean out your intake valves with ease. After a few hours with us, you’ll be driving the South Florida coastline with confidence.

You’ll notice several carbon build-up side effects, including:
  • Loss of power
  • Engine misfires
  • Sluggishness
  • Engine warning lights
  • Longer engine start times

Benefits Of Walnut Blasting

The removal of carbon deposits from your engine will present some noticeable benefits. These include:

  • Smoother idling
  • Improved fuel economy
  • Better acceleration and response
  • More horsepower

Regular engine cleaning helps to prevent wear and tear on your engine. The mechanics at Foreign Affairs Motorwerks can advise you on the right scheduled maintenance plan for your engine. Regular vehicle maintenance is the key to prolonging the life of your engine.
