What's your preferred cleaner or method for the intake valves? Do you think this performance is worth buying the CRC intake valve cleaner? 🤔

It says give it 1000 miles to get cleaned i assume ut weakens carbon and over time bits of it break apart. Also probably 3 cans will make a decent difference?

I got better results after doing it again 2 weeks later.

The videography of the valves is very good. I am certain that the product will clean the residue off of the ports before it cleans the valves.

The reason the valves looked slightly cleaner after those several days is because the CRC cleaner actually states that it continues to clean over the next few days following the initial application of it. Every video I watch is so critical of the results of these products they expect it to remove intake valve carbon deposits and restore them to like new condition just because the picture on the can shows it like that but nothing except an actual walnut blasting service will remove carbon deposits from intake valves enough to make any real difference and the results of these store bought products cannot produce results to that of a walnut blasting service. It's expensive but walnut blasting is worth the price I get it done on my WRX every 20K but of course I'm an auto shop manager so I barely pay anything to do it myself at work lol. But I do use these chemical products in between walnut blasting every 20k miles or so at each oil change and I perform full service oil changes every 2K miles so at each service I run a can of it thru as a way to keep the intake valves and system clean and maintained to prevent further buildup. So a walnut blasting service every 20K with a can of CRC every oil change every 2K to keep it clean. Of course I'm very anal about overly frequent service but it barely costs me anything cuz I manage a service shop but it's a good plan to follow for anyone. But only a walnut blasting will truly remove deposits these cans of cleaners can keep the intake valves clean but they won't actually deep clean anything I mean think about how insanely hard carbon is and how stubborn it is to remove it requires strong but safe abrasive cleaning action like walnut shell media shooting at it under crazy high pressure at close range to get that crap off the valves no store bought cleaner is gona do anything like that lol

Neat study, I like how you present your vids. I wish I knew, but you did give those intake valves, and ports a wet look. Now I can't help but wonder if that carbon will eventually come off over a month or several months since the carbon is now 'wetted' and saturated with whatever chemical was in the CRC cleaner. Great vid. Liked👍

Great video

Amazing info. Which valve cleaner is recommended for Toyota cars. Also is there a way to use without the technically skills you used in this video? There are loads of product sold at gas stations and they simply empty the contents into the fuel thank 🤔

I agree with veganlogic4empathy, I also like how you present your videos. Thank you

I think the best is walnut shell blasting

I am going to do this every 10k miles in addition to the catch can on my wifes new Kona. Prevention is the key

Does this carbon / particles find its way into cylinders and score cylinder walls or bash rings ???

In summery...it doesn't clean well enough, it's a waste of time. The ONLY way is to manually clean and intake manifold MUST be removed along with a whole lot of other related parts to properly clean the back of valves AND the intake ports. It's a rather time consuming (and expensive) process. Walnut blasting is the standard for this procedure.

I agree. After watching some other videos on KZfaq and yours, I appreciate your Honesty, it's clear that using GDI cleaner from a can is not a big improvement. I'd say, unless you are having actual issues with Carbon Build-up like hard starts, misfiring, poor acceleration, etc., then just leave it be. And if you need a cleaning then spend the money and time and remove the Intake Manifold and get inside there and scrub them clean the right way.

Have you tried Amsoil powerfoam?

Keep in mind that whatever it does clean, makes it’s way into your catalytic converter. Priced those lately?

Very nce test. I've seen similiar one on AliMECH channel and results were equally pathetic. I have 1.6 N14 engine [aka THP] and recently sprayed a can of Xado Anticarbon through a PCV hose, seems like done something, but I do it only preventively, my valves were cleaned mechanically 4000km ago. I can recommend Xado, it's really serious chemical agent.

if you do it from the first oil change it works better if you let it build up like yours only a manual cleaning will work

I'm guessing its going to take a boat load of cans before you see a good result which in my opinion is to be expected.

Just like the videos who specialize in walnut blasting & manual cleaning of intake manifolds say. These cans only make negligible improvements. And also show only benefits on the walls, not the intake valves.

Gotta try the ATS treatment and see how it does.

Haha, it’s called marketing. Most people will not check to see if it works and will get a placebo effect thinking it did. 8-)

Gdi engine?

You have to spray directly into throttle body, not a vacuum line, that’s why it’s not cleaning much. - Mechanic of 25+ years

Waited too long.. These cleaners only work on soft carbon build ups. Hard caramelized carbon caking needs mechanical cleaning.This process only works on new engine at 15000-25000 mile intervals.

Why dont people use water/meth injection?

Maybe the manufacturer forgot to add information that this product was created and designed specifically for vehicles with a mileage of under 500 miles...😂

Damn instead of buying CRC intake valve cleaner, buy a car with direct + port injection instead.
