A » Direct injection engines often suffer from carbon buildup on intake valves due to a lack of fuel wash. Common solutions include using high-quality detergents, walnut shell blasting for physical cleaning, and regular oil changes to minimize deposit formation. Implementing catch cans can also help reduce oil vapors contributing to buildup. Regular maintenance and adopting these measures can significantly extend engine life and performance.
