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…..

Courtesy cars updated

For 5 years we had 3 E46 BMW’s running around town. The name change was a great opportunity for trade up to newer, with fewer kms.

So 2 of the BMW’s have been sold and gone to new homes. TOY001 I just couldn’t let go….Maybe its time??

So we have added a MK5 Golf GT,

And new to us, not yet signed up is a 2010 MK6 Golf wagon.

Also yet to be decided on is the A4 Audi in the background. This might be the new TOY001 if i can finally part with my old BMW

 

Wow, has it been a year for WEEU

We’ve done everything we set out to do 12 months ago, We’ve added a hoist, bought more tools, changed up the loan cars and more…

BUT!!

There’s always more to do, improvements to make, and more cars to service and repair…

Watch out for the 12 month summary blog!! And whats up next…
