While watching lots of videos on YouTube I stumbled upon this in my recommended, and I never heard of this cleaner I was wondering if anyone had any idea as to whether or not it would work on an n54 if it works like he says it does on this ecoboost in theory it should work for us, it would this be just as ineffective as seafoam is. I did a walnut blast about 15k miles ago I was wondering if this would help between my cleanings.

PS: I got in a comment argument with this same guy as to why BMW chose to forgo the dipstick on our cars.

[Antetokounmpo]

yeah... no. as soon as he said drive at highway speeds for 10 min i was done.

[El Cheapo Loco]

Didn't even watch the video. Just look at the guy... he looks shady af.

[max_330i]

I agree it's probably BS. It's just a relabeled can of seafoam. It's like those health gimmicks-- cures all ailments, contains nothing... yeah right.

I don't think I would even do this on my 2005 Saturn vue...

There MAY one day be an injector cleaner that will work for cleaning the injectors in our cars; hell, there might even be one now....

BUT

That will do absolutely nothing for helping you prolong periods between walnut blasting, or help with anything to do with walnut blasting.

Two reasons:

1. The injectors have nothing to do with the reason we have to walnut blast; that's a crankcase ventilation issue.

2. The injectors appear AFTER the area of concern that leads to walnut blasting.

Clean your injectors all you want; you may even be able to prolong injector life (some); but even with the world's cleanest injectors, you'll still be walnut blasting at the same intervals (unless you upgrade the PCV system).

Thanks for the help, I wasn't too hopeful but I figured it was worth a shot. I bought all the tools to walnut blast so it's not expensive and not that hard of a job either.

Well, I theory injectors have everything to do with why we have to walnut blast.

Their location is the main cause for carbon build up in conjunction with oil blow by product from pcv system.

Injectors have everything to do with the issue. If we had PI we wouldn't have this issue. Every other DI only engine has this exact same issue.

Yes, the injector placement, and the lack of fuel washing across the valves is the reason carbon build-up on the valves exists to the extent that it does on our engines (as with all DI-only designs).

Will that change by cleaning your injectors?

Will that change if you install brand new injectors?

No.

My point stands.

See my post above.

You can't blame it on the pcv system. Sure, it's not great on the n54, but if that problem didn't exist we'd still have to clean the valves due to others inherent issues with DI engines. A lot of engines have poor pcv systems, vr6 engines come to mind and they have pi and don't get gunked valves...

I think you're missing the context of my reply (and the OP's post).

My reply to the OP wasn't intended to be a thesis on the flaws of a DI-only design, and how that contributes to carbon build-up.

His post was hopeful that cleaning his injectors would help his need to walnut blast.

It will not.

Keep them as clean as you can, even replace them, it will not impact the rate at which you have to walnut blast.

The injectors, themselves, aren't the cause. It's the design of the engine, and the injector placement, that is the major contributor - and that will not change based on the functionality of the injectors themselves.

I referenced the poor factory PCV system because it IS a major contributor the the rate of which these engines have to be walnut blasted. For clarity: NOT that we have to walnut blast, but how often.

Other DI-only engines don't require walnut blasting at the same frequency as the N54. Why? More robust PCV systems.

If you want to extend intervals between walnut blasting, look into beefing up the PCV system. This will help EVERY N54 on the road today.

Sure, PI will work great, but that's a solution that's not practical for the average (stock) N54. A better PCV system is.

BG has some good products, the problem is one has to take off the intake manifold, just like you would do the walnut blasting. The upside is you don't need to fiddle with vacuum cleaner and worry about walnut "lock". You need to know TDC. Problem is, the engine needs to be hot and it takes about 15min/cyl for the product to soak. This the product, vid below.

[robthewrench]

The better oil separation system in the PCV path of the N55 is why N55s do not need walnut blasting on nearly the frequency of N54s. I agree with the previous poster that cleaning your injectors in a DI engine will do nothing to clean carbon build up in the intake of a DI engine. You'll need to clean the intake tract, not the injectors.

[Boland01]

I just purchased the RB external PCV valve delete and Mitsubishi catch can for the low side. Had already installed the BMS catch can system on the high side.

It's been 7K since I last walnut blasted the car. I'm hoping this will cure the need for any future walnut blasts. I guess time will tell.

The premise of the original video, in theory, is correct, but I have no idea if the cleaner used is capable of actually breaking up the carbon deposits.

Some people in previous posts are talking about the injectors, the process in the video has NOTHING at all to do with the injectors. The injectors deposit fuel directly into the cylinders, the video was clearly showing the cleaner being added to a vacuum line.

The engine is basically a large air pump. Air is pulled into the engine through vacuum lines. This air passes over the intake values, where the carbon build up is present. So, by inserting the cleaner, into a vacuum line, you are able to get the cleaner onto the carbon deposits, but is it able to clean them? I have no idea.

I doubt this process can clean the carbon deposits, while the vacuum will pull the cleaner to the valves, it will also pull it off them, and into the cylinder. This is why the other video is showing the cleaner put directly onto the valves, and allowing it to sit - so it can actually sit and clean them.

I honestly doubt that this cleaner can remove carbon buildup on the intake valve, with the small amount that is pulled over them - he did use the entire can though - but I do think it's possible that doing this could, if done fairly regularly, could limit the amount of carbon buildup that occurs.

I am someone about to clean mine. Everything i have gathered is that chemicals will clean about 60 to 70 percent. The thick sludge it will not, that's when you either have to walnut blast or manually clean with a gun kit.

I cannot afford to do walnut right now, we just had a kid. So I will be pulling everything off, soaking in cleaner and scrubbing. I'm going to replace plugs and coil packs as well and she should be good as new. Catch can installed, new turbos already. :-)

[Mashman]

FYI - I just looked, and found a video from CRC, the manufacturer of the cleaner.

I also found test results on CRC's website. http://crcindustries.com/gdi/#testresults

[Faredo]

So this guy uses it on an N54 and the stuff plowed through that buildup with no scrubbing.

[EB89]

Yeah you should use this and also 3 bottles of stop leak in your radiator.

Scrub all the big carbon deposits off first BEFORE you use any crc. Then vacuum out what you can. Repeat. Use crc at the "end" once you have scraped most of it out. The reason being is, once you use the crc, the carbon turns into a paste form and is much harder to deal with.
