Walnut Blasting Intake Valve Decarbonization
Direct-injection (GDI/TFSI) engines accumulate heavy carbon crust on intake valves over time. We utilize pressurized fine walnut media to blast away baked-on carbon deposits without engine disassembly, restoring 100% factory volumetric efficiency.

Symptoms & Diagnostic Fault Codes Resolved
DIAGNOSTIC MATRIXP0300 - Random Misfire on Cold Engine Start
P2006 - Intake Manifold Runner Control Stuck Closed
Symptom: Sluggish throttle response and loss of top-end horsepower
Symptom: Rough erratic idle during morning engine warm-up
Sequential Workshop Bay Execution Gates
1
Stage 1: Intake manifold removal and 4K borescope photo inspection of all intake ports.
2
Stage 2: Manual crankshaft rotation to verify complete valve closure for each cylinder before blasting.
3
Stage 3: High-pressure crushed walnut shell blasting restoring valves to factory mirror-finish metal.
4
Stage 4: High-vacuum media extraction, fresh OEM manifold gaskets, and ECU throttle adaptation reset.
