A Volvo V90 stopped by our service center.
The owner found out about our service online: walnut blasting the intake tract.
We successfully completed the service, and you can see the before and after photos below.
The customer was very satisfied.
Walnut blasting the intake tract is one of the most effective methods for removing carbon deposits from intake valves, especially on gasoline engines with direct fuel injection.
Key Benefits:
- Effectively removes carbon deposits. Walnut shells clean even thick deposits without damaging the metal of valves and intake ports.
- Restores engine power. After cleaning, the engine breathes easier, improving cylinder airflow.
- Improves throttle response. The car becomes more responsive during acceleration.
- Stabilizes idle speed. Vibrations and rough running caused by intake contamination disappear.
- Reduces fuel consumption. If the intake is heavily contaminated, fuel consumption may decrease slightly after cleaning.
- Reduces the risk of misfires. Carbon deposits can interfere with airflow and cause engine performance problems.
- Engine safe. Walnut shells are hard enough to remove carbon deposits, but softer than metal, so they won’t scratch parts.
- No harsh chemicals are required. This mechanical cleaning method is often more effective than chemical cleaning.
