Walnut-Blasting Carbon Clean/ Engine Detox

We are calling this our Stage 3 clean. Stage 1 being Hydrogen Carbon clean machine. Stage 2, Hydrogen Carbon Clean machine and Liquimoly intake cleaner.

Stage 3 Walnut Blasting

Stage 4 = All of the above

What is it? quite literally its a machine that uses compressed air and fine crushed walnut shells to remove carbon build up. In our application, usually intake ports and the back sides of intake valves.

Why do it? Alot of modern engines by design are prone to carbon build up in the intake system, over time as the carbon build up increases the efficiency of the engine reduces, meaning less performance, fuel economy etc.

Why now for WEEU? We deal with a lot of cars that suffer from carbon build up, and a lot of our customers like to keep there cars no only going, but going like they should! We follow a lot of forums and in recent times have seen a lot of discussion on this topic. We also dont know of many local workshops that offer this service so decided now was the time. Its also a good fit with our other Detox Tools and Tuning service we now provide.

Whats involved? There is some time involved and the time taken varies from car to car. We do have to remove the intake manifold to gain access to the intake ports, this can mean on some cars, intake runner flaps also need removing. Each cylinder is done separately as the valves need to be in the closed position so as to not fill the cylinder with walnut shells, all other ports are masked off etc to avoid walnut shells going where they are not wanted.

A bit deeper in, still the intake runners to remove.

DTI used to help with piston location/ valves closed etc. Not required but better safe than sorry. Engine bay taped off with plastic sheet, overkill maybe!! But we dont want walnut shell in everything. Machine uses a large vacuum fitting to pull the majority of the shells out, and a metal wand goes down the center for the actual walnut blasting

I love the old saying, ‘the proof is in the pudding’!!
Great feedback from the customer re the end result. We could tell from start up that the car just sounded crisper and more responsive.
