Most workshops in Singapore won't admit that they:
❌ Don't remove the intake manifold
❌ Don't use real walnut blasting machines
❌ Don't clean injectors
❌Don't borescope before or after
❌Don't understand DI carbon issues
❌Don't show proof of what they've done
So your car still feels sluggish after they "service" it.
We do the real job, with proof and full restoration — not shortcuts.
Carbon Deposits Buildup Inside Intake Valves
What Exactly Is Walnut Blasting (Simple Explanation)
What Exactly Is Walnut Blasting (Simple Explanation)
Walnut blasting is a professional carbon cleaning method that removes hardened carbon deposits from your engine's intake valves.
This carbon forms because direct-injection (DI/GDI) engines DO NOT wash their valves with fuel, unlike older engines.
So, oil vapour, soot and unburnt fuel bake onto the valves.
Layer by layer.
Year after year.

Are you experiencing any of the following?
Loss of power
Hesitation under acceleration
Rough idling
Poor fuel economy
Misfire codes (P0300 - P0304)
High fuel consumption
Poor throttle response
These WILL NOT get better on their own.
Chemical cleaners cannot reach these valves.
Walnut blasting is the only proper method used worldwide by BMW, Audi, Volkswagen, Mercedes and performance workshops.

Carbon Deposits Hardens Overtime
Why Carbon Forms
Why Carbon Forms
Carbon buildup is guaranteed on any direct-injection engine because of:
PCV oil vapor blowback
EGR recirculation
Stop-go Singapore traffic (hot engines, slow airflow)
Short trips
Turbocharged systems
Low intake airflow at low rpm
It's not your fault — it's how modern engines are designed.
This is why all GDI engines require periodic walnut blasting.

Why Walnut Blasting Is NOT a "Quick Job"
Why Walnut Blasting Is NOT a "Quick Job"
Real walnut blasting is labor-intensive:
Intake manifold removal
Port sealing
Cylinder-by-cylinder blasting
Injector servicing
Adaptation reset
Cleaning and assembly
Testing
Some engines (BMW/Audi/Mercedes V6/V8) require partial or full engine removal to reach intake ports.
This is why we quote based on engine layout, cylinder count & access.

What is walnut blasting and how does it clean my engine?
Walnut blasting is a professional carbon cleaning method used to remove hardened deposits from the intake valves of direct-injection (DI / DGI) engine. We use finely crushed walnut shells to safely "sandblast" carbon without damaging metal. This restores airflow, combustion efficiency and engine smoothness.
How do I know if my car needs walnut blasting?
How do I know if my car needs walnut blasting?
Common symptoms include:
Jerking or hesitation between 1,500 - 2,500 rpm
Rough idling or shaking on cold start
Loss of power
High fuel consumption
Misfire codes (P0300 - P0304)
Sluggish throttle response

How often should walnut blasting be done in Singapore?
How often should walnut blasting be done in Singapore?
Most DI engines require walnut blasting every 50,000 - 80,000 km, depending on driving conditions. Short trips, traffic jams, turbocharged engines and hot climates cause carbon to build up faster — sometimes even as early as 30,000 km.
Is walnut blasting safe for my engine?
Is walnut blasting safe for my engine?
Yes. Walnut shell media is non-metallic and does not scratch valves or ports.
We:
Seal each cylinder
Blast one port at a time
Vacuum continuosly
Recheck with borescope after cleaning
It's the method recommended by BMW, Audi, Volkswagen, Mercedes and most performance workshops.
Why do you include injector cleaning as part of the service?
Why do you include injector cleaning as part of the service?
Carbon buildup affects airflow, but clogged injectors affect fuel delivery. To restore full performance, both must work together. We ultrasonically clean, flow-test and balance your injectors using our machine — a step most workshops skip completely.
How long does walnut blasting take?
How long does walnut blasting take?
Typical jobs take 3-5 hours, depending on carbon buildup, number of cylinders and type of intake valves.
