Intake Decarbonization
Walnut Blasting in Lethbridge
Modern engines are powerful and efficient, but over time, carbon buildup can rob them of performance. At Mr. Mechanic Auto Repair, we’re proud to be one of the only shops in Lethbridge offering intake decarbonization using walnut blasting — the most effective and safe way to clean intake valves on direct-injection engines.
What Is Intake Decarbonization?
In most modern direct-injection engines (like those from BMW, Audi, Volkswagen, and other European makes), fuel no longer washes over the intake valves. As a result, oil vapors and carbon deposits gradually build up on the valves and intake ports. This buildup restricts airflow, reduces power, and can cause misfires or rough idle.
Our walnut blasting process uses finely crushed walnut shells and compressed air to safely remove those deposits — without damaging your engine components.
Benefits
Whether it’s a slow leak, puncture, or visible damage, our team provides fast and reliable tire inspections and repairs. We’ll assess the issue, recommend the safest fix, and get you back on the road with confidence.
