Carbon buildup has become a major issue for modern motorists, affecting engine performance and efficiency. This video explores what carbon buildup is, what causes it, and how you can remove, reduce or prevent it. We also discuss how manufacturers and car enthusiasts have tackled this problem with innovative solutions and modifications.

What is Carbon Buildup?
Carbon buildup refers to carbon deposits forming around the intake and valves in the engine. This can significantly restrict airflow, potentially reducing your engine’s performance by up to 60%.

Causes of Carbon Buildup
Direct Injection Engines: Unlike older port injection engines, modern direct injection engines don't wash the intake valves with fuel, leading to carbon deposits.
Exhaust Gas Recirculation (EGR): Recirculates some exhaust gases back into the intake to reduce emissions, introducing carbon particles.
Positive Crankcase Ventilation (PCV): Vents excess pressure and oily vapors into the intake, creating a sticky surface for carbon buildup.
Mitigation Strategies
Use HighQuality Fuel: Ensures cleaner combustion, reducing carbon deposits.
Injector Cleaners: Keep injectors clean for efficient fuel spray and combustion, though they don't clean intake valves directly.
Regular Maintenance: Long drives help reduce carbon buildup by keeping the engine running efficiently and burning off residues.
Modifications to Reduce Carbon Buildup
Oil Catch Can: Traps oil vapors from the PCV system before they reach the intake, keeping it cleaner.
EGR Delete: Prevents carbonladen exhaust gases from entering the intake (note: often illegal for onroad use).
Port Injection Retrofit: Combines port and direct injection to help clean the intake valves.
Cleaning Carbon Buildup
Intake Sprays: Can be effective but require repeated use and careful application to avoid engine damage.
Professional Intake Cleaning: Computercontrolled cleaning processes offer thorough and safe cleaning.
Walnut Blasting: Uses crushed walnut shells to effectively clean carbon deposits without damaging engine components.
Manual Cleaning: Using solvents and abrasives with caution to avoid engine contamination.
Engine Types Affected by Carbon Buildup
Large Capacity, LowRevving Engines: More prone to buildup and may require cleaning every 20,00030,000 miles.
Small Turbo Engines: Less prone but still need attention, typically every 70,00080,000 miles.
Final Tips
Avoid short trips, keep your engine wellmaintained, and consider these modifications and cleaning methods to keep your engine running smoothly and efficiently.
