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.

Audi A4 Engine Failure 1.8T

Audi A4, broke down just up the street from ‘WEEU’. Customer decided to not proceed with a repair so we took the car off their hands as a project. Its been parked up for some time now. October we finally got it inside to see the extent of the damage, all we know is the engine sounds horrific, and we suspect the timing chain has skipped teeth….
We removed the top cover to expose the top timing cover glued on and missing bolts. This is definitely not the type of work we let out the door. not a great start!!.


Front cover off, we found the chain guide at the very top broken and missing. This has left the chain slack and we can now confirm the timing has jumped. A quick cylinder leak down test confirmed bent valves on the first cylinder tested, so next move is to remove the cylinder head….

So with the head off and at least 8 bent valves we then discover a broken piston. This really is worst case scenario that we had hoped to have avoided, however it is what it is. Now to weigh up, do we rebuild or replace…. Currently pricing a replacement used engine and costing up a rebuild. Watch this space.
A bit of work to get it to here, next move will be to remove the engine…..

Diesel Tune NZ

We are excited to announce that we have teamed up with Diesel Tune NZ to be one of their official NZ dealers.

Check out the link to their site, put in your vehicle details to see what gains can be had with a stage one tune, and in many cases with Diesel Turbos, some fuel gains to be had. Diesel Tune NZ

Check out what a stage one tune will do for my car

Why Now?

We have facilitated many tunes, however its been something we’ve outsourced, and struggled to answer questions quickly around, what are the gains? What price? and when can you do it?.

Now we will be able to provide this info on the spot. and time frames we can manage based around our own workshop loadings…. Wins all around.

We will look at combination deals also around engine detox (Carbon clean and walnut blasting) followed up with a performance tune.

About DTNZ

Diesel Tune NZ, is a nationwide franchise giving us huge support, and although the name implies Diesel Tunes, we can do petrol’s as well, our first tune being a Mini Cooper S Turbo. See further down for pics and results, its now a little rocket!!! Customer feed back is “Im struggling to wipe the smile off my face”

Sample

Sample, We are tuning Our Diesel E-Class E220. Take a look at the what we can expect to see, hp, nm and economy gains… A massive 100Nm of added torque. Looking forward to this!!

Huge selling point here with most Diesel Turbo’s. Fuel gains to be had. We will be putting this to the test with our Mercedes.


Prepping for tuning, obviously some basics need to happen… Ie, no current faults. We had no check lights on in this car but to be sure we run a full report on all systems, in this car our tool of choice is the Autologic.
As with most work we carry out now, even services, we connect to a battery support. We now have 4 battery supports which are running most of the day. The battery support will maintain a steady voltage, which while doing any sort of electrical work, coding, programming etc is critical. We purchased this battery support to be dedicated for the remapping of cars

First Tune went extremely well!!

Training is in session, a long time customer of ours put his hand up to be the first tune done in-house by WEEU and DTNZ. Craig from DTNZ did all the hard work while we observed….
Subject, Mini Cooper S

All tunes come with a ‘Diesel Tune NZ’ certificate.

This is the smile before Stuart even drove the car, Check out his FEEDBACK
