WOW!!!! I'm genuinely shocked how much carbon there is inside a low milage petrol engine! God knows what the inside of my 155,000 mile M57 looks like.

Great video! I didn't know it was just 12 seconds. Just to make clear to people, the carbon build up is so bad because it's DIRECT INJECTION and fuel doesn't go over the tops of the intake valves, it is injected directly into the cylinder. Non-DI engines have the fuel injected into the intake and it "washes" over the intake valves. The N54 is especially bad at carbon build up. The N55 has a recirculation which is supposed to help some but not sure how effective it is. Some manufacturers are adding some injection before the valves to help with this I believe. I use CRC DI cleaner every few oil changes to help, but it won't take off serious build up like this. You can buy the little vacuum attachment for about $25 and get a walnut set up (if you already have a compressor) for around $50-$150 depending on how fancy you want (if you're in the US, they sell at Harbor Freight for cheap). You just have to take off the intake though of course.

The volves?

Really well filmed, informative video.

Never heard of walnut blasting, and I've been a mechanic for 25yrs! lol. And my 330d needs this! (and all diesels!)

Did you get it done?

Brilliant video

When you see the intake ports in makes a very good case for oil catch cans

Well thank you for answering some questions below👍👍👍

Keep uploading these videos! The work you do is on another level and your explanations are well informed and logical without being dry (at least IMO).

Great work again from James & the boys👌

I love watching your videos. So professional with what you do. If only you were near me!

Excellent and interesting video thank you

If I had a BMW I’d use reddish. Top class company

Nice job

Good video, I had this on my mini. Cleaned it when we first bought the car, 2 years later i stripped the engine cleaned and polished the valves

How many times do you take it to get cleaned just purchased a mini and am more frantic than ever haha!

One more excellent video

Did similar to an OHC Mazda engine that was drastically failing the smog checks. All I removed were the spark plugs. Fastened a soft copper tube to a harbor freight blaster air gun and curved it, inserted through spark plug hole at TDC, and blasted away the combustion chamber with fine walnut shells. Blew out with clean air. Engine's exhaust emissions were then 1/4 of limit! Seemed to have more power as well.

Absolutely brilliant ❤️. I wish I knew you guys before I have been robbed with 2.5k for a similar job somewhere in Newport 🙈

That is absolutely incredible. I cannot believe that that little bit of mileage that the valves look like that. You would think BMW would have some sort of service bulletin out. I'm not sure on European cars but American manufacturers put out service bulletins one things they have found out that should be addressed sooner not later. I would think with these valves on the BMW that's something that should be done at least every 30,000 miles. I just think it's great that you have tools that stop you from having to pull the whole entire head off. As you know when you do that you are opening up a possibility for a failure point I must definitely hit the like and subscribe button on your video. I enjoyed the video I am looking forward to watching more of them. Thank you for sharing your knowledge on how to resolve this problem. I don't believe in the chemical method. I have never seen a single product that dissolves deposits like this in the real world.

I think I need this on my Z4 35iS. It's been running rough idle lately, has 75k miles and never has been walnut blasted before. Couldn't be the injectors because they were all replaced less than 3 months ago.

If i hear vOlves one more time i will faint. Other then that love the work very professional 🙂

Came here for this comment 🤣🤣🤣

What was the compressor's settings in terms of PSI & CFM?

Would an Oil Catch Can help to reduct carbon buildup? Considering the labour to do such a walnut blast in Australia can be 1k+

Did the camera breath easier after having the blast?

Hi, was any difference noted? If so, in what way? I have one with a nervous idle and LOTS of carbon sludge on the valves... but seems to run just fine when its warmed up... Thank you...

Part of me wishes you did before and after borescope shots, but the other part knows just how sticky and horrible that stuff is and what a pain it would be to clean off from a borescope shaft let alone a camera lens.

Did anyone else notice the irony that the intake manifold that is supposed to last the life of the car is plastic whereas the tool you use to clean the valves is aluminum?

whats a volve? sorry if this sounds daft i thought they are called vAlves?

can you write BMW OEM number of blaster Cylinder Head Adapter for N47&N57 engines?

Thé VOLVÉ. 😂😂😂😁😁👍👍👍

I think you mentioned something about a torch also?? I didn't see any use of a torch?

Who come with this idea . Unbelievable 😊

should be a recall issue for all gdi engines

What psi is recommended to walnut blast with?

And what about the plastic intake manifold? Can't imagine that whould be much cleaner on the inside.

thats what i want to know too as there are valves too which needs to be cleaned

what about intake manifold ?

How much would it cost for a N47 engine

It's a valve not a vulve!

do you give them a quick wash out with anything to get the last few bits of walnut out or do they not do any harm to the cylinders?

The walnuts don't damage anything. The odd few that get caught in there get burnt off and smells nice

Volves or valves ???

The vulvas

Just curious.... I have a BMW F30 335D X Drive with the N57 engine which of course has 6 cylinders. If this is relatively quick process, why is the cost as high as it is? The cheapest quote I have seen for my vehicle is £469.50 for 4 hours of labour, new seals and the walnut shells. Next cheapest was £500 then followed by a whopping £695. They estimate it will take 3-4 hours.... I appreciate that to conduct this process the inlet manifold has to be removed, but if the process of cleaning each cylinder only takes perhaps up to a few minutes (you specified 12 seconds in the video), why does the whole process take 3-4 hours? I'm going to be having this process done within the next 2 weeks, my vehicle has covered 89,500 miles (67 reg) and the previous owner was a right cheapskate and hardly maintained the vehicle at all, so I doubt it's ever been done.

Why walnuts?

FFS someone please tell this bloke how to pronounce "VALVES"

Can this be used on any manifold of any car

not all engines need this type of cleaning. only those with direct injection (diesel or GDI) get bad carbon build up. normal port-injected cars get a little carbon, but the valves are generally pretty clean. this process, however, is for cleaning the ports, not the manifold. that said, a walnut blast setup like this should work on an intake manifold. the hard part is containing the mess. the aluminum under that he connects the vacuum to is a bmw part, specific to the port opening, and pretty specific to the engine. the diesels, for example have two port openings per cylinder, and they are different shapes, so it requires two of those special shop-vac adapters. there are a wide variety of 3D printed port adapters being sold on ebay, the ones i've purchased or have experienced personally have been low quality - nothing like the aluminum bmw pieces.

What on earth are volves??!!! 😂😂😂😂😂 A little concerning that the finished inlet tracts still had evidence of walnut shells . . . they need blowing clear after each cylinder has been blasted or they will be drawn into the cylinders . . . . A lot of trouble to go to only to not bother with an important finishing touch!!

Voles are small rodents that are relatives of lemmings and hamsters, but with a stouter body; a shorter, hairy tail; a slightly rounder head.

But the important thing is that it emits 3g of CO2 less per km than if it was port injected, so...

That isn't an accent thing. That's the wrong word.
