A customer brought in their European vehicle, reporting rough idling and reduced engine performance. Upon inspection, we found that the intake valves were heavily clogged with carbon buildup, a common issue with direct injection engines.
Our technicians performed a thorough diagnostic, identifying significant carbon deposits on the intake valves. This buildup was causing airflow restrictions, negatively affecting the engine’s performance and fuel efficiency.
To address the problem, we recommended walnut blasting. Our team carefully disassembled the intake manifold and used crushed walnut shells at high pressure to clean the intake valves, effectively removing all carbon deposits. After the process, the engine’s airflow was restored, leading to smoother idling, improved performance, and better fuel efficiency. The customer noticed a significant difference in the vehicle’s responsiveness and overall drive quality.
With years of hands-on experience in servicing European vehicles, our team has quickly built a reputation for reliability and excellence.
