Non-invasive intake valve cleaning with walnut shell blasting in a closed-loop vacuum system.
No hidden payments and no repairs without customer approval.
We scan for misfires and inspect intake port carbon levels with a borescope camera.
We remove the intake manifold and crank the engine so target valves are completely closed.
We blast the valves with crushed walnut shells under pressure while vacuuming away carbon instantly.
We install fresh intake manifold gaskets, reinstall hardware and adapt manifold runner flaps.
We show you pristine borescope camera results and verify smooth engine performance.

Standard turnaround at VS Serwis is between 4 and 6 hours. Drop your vehicle off in the morning and collect it in the afternoon with full power restored.
No. Each intake port is cleaned only when its valves are 100% closed, and a dedicated vacuum adapter extracts all blasted media simultaneously.
We recommend walnut cleaning every 60,000 – 80,000 km, or every 50,000 km for vehicles driven primarily in stop-and-go city traffic.
Cold start hesitations and rough idle disappear, original throttle sharpness and horsepower return, and average fuel economy improves noticeably.
