- As your car ages and accumulates miles, you may notice a gradual performance degradation with your engine power, performance, and efficiency. You may experience poor engine idle, low mpg's, sluggish acceleration and engine knock. One of the culprits could be carbon accumulation that occur either in your combustion chamber, on the intake valves, and on the fuel injector tips. We'll show you a quick and easy way to remove these carbon deposits and build-up using a cleaning agent with an active ingredient called PEA.

Thanks for the vid. I would recommend avoiding use of the brake booster on GDI platforms as it may not allow the solvent to remain atomized before hitting the intake tract. In talking with CRC, they also strongly recommend the intake tract anywhere after the MAF. An optimum spot would be just before the TB, so the spray is distributed more evenly through the IM (and subsequent valves). Insert the straw between the couplings before the TB (taping if needed) to ensure no unmetered air gets through.
Hope that helps.
Thanks for your post! Really up to you where you want to introduce the solvent. I'd assume that at 2,000 rpm or higher the solvent would be getting sucked in too fast to lose its atomized status. BTW - The whole purpose of this exercise is to remove carbon: from the intake valve bulb; around the tip of the fuel injector tip; inside the combustion chamber. I've discovered awhile ago that carbon removal can be done with atomized water. The technology or method came about during the WW II. At that time it was called "methanol injection". The methanol was added to water to prevent it from freezing at high altitude. Anyway, introducing atomized water leading into the combustion chamber "cracks" carbon off of metal contact surfaces. So I experimented by 1st cleaning with atomized water. After a few days went by I did the CRC treatment. Guess what? No smoke! ... indicating what? ... engine was virtually carbon free?
Hardly Moving Production
Could you please expand on the abbrev. so most people can understand? I had enough acronyms in the Army...
The White smoke is not really the carbon burning off, it’s the cleaner being burnt. I’m not saying this procedure doesn’t clean the carbon, but the white smoke mostly cleaner.
I've done this procedure spraying in pressurized misted water and it produced the same result: lots of white smoke. When the water vapors hits the combustion chamber, the carbon flakes off and gets burned out. After around 10 minutes (in extremely carbonized engines), the smokes clears up regardless of the continued water injection. The white smoke also gives off a funky smell ... that's got to be carbon burning off. I'm assuming the catalytic converter is working overtime (since it acts like a mini furnace) burning up the carbon. Ironically, I think the misted water introduced in the air intake works just as well as the chemical cleaner. You have to be extremely careful how much water you inject to prevent hydro-lock; which can bend your connecting rods.
Fantastic video. Best explanation ive heard so far that i can make sense of.
Glad you found it helpful!
Never had an issue with either of My earth dreams Hondas current car is a 2019 CRV 1.5 t and its done over 150,000 miles, the Honda Tech at my dealership stated to me last year that carbon build up on these engines is extremely rare as Honda mitigated this as a proportion of the intake valves do get a spray through overlap and the valves are designed to rotate to give an even clean, they did offer a cleaning option if I wanted which I believe was crushed walnuts ? but I declined as it was pretty pricey, car never misses a beat , pretty impressive IMO. Car always runs on Premium fuel and gets a drop of injector cleaner in the tank every 3000 miles.
Thanks for sharing your ownership experience. Good for you that you haven't experienced any carbonized intake valve problems with over 150,000 miles. When problems do happen, the amount of carbon buildup inside the intake ports and on the valves is not to be believed! Toyota addressed this intake valve carbon accumulation problem by having 2 injectors per cylinder; both port and direct injectors. What their engineers discovered was in certain driving conditions, port injection was more efficient that direct as well as having both working simultaneously. A short time later, Hyundai began providing dual injectors on their high end 2.5L engines.
Using premium vs regular fuel along with injector cleaner has no effect on keeping intake valves clean since fuel never touches the intake valves.
really great tutorial thank you
Glad it was helpful!
I kinda need to do this to my Accord, that said I have to imagine PEA offers little for this type of application. It as a detergent isn't bad, but its not super effective for carbon. Its claim to fame is being able to survive in the combustion chamber.
Most will burn up instantly doing basically nothing for pistons, PEA will absorb into the carbon on heads to slowly break it down. Its not a fast acting cleaner, its mild, but its about the only option for cleaning heads, at least while the motor is at operating temp.
This seems more like a fast clean is all, PEA shouldn't be able to do virtually anything during the time it takes to empty the can. My only guess is they have multiple cleaners to clean rapidly (since lower temps) and the PEA is just there to break down any remaining carbon in the long run (if any carbon remained at all).
All good points and thanks for sharing! What I've found, from trying different methods, is using a product call B12 Chemtool which is sold as a fuel additive for cleaning fuel injectors. If you take off the intake plenum to expose the intake ports, pouring in the chemical (with both the intake and exhaust valves closed of course) will eat away the years of carbon accumulation on both the valves and port walls very quickly! As of late, I've been rebuilding Hyundai Sonata 2.4L I4 engines. With the cylinder head off and tilted on the side, I just pour in the Chemtool and let it sit for 10 minutes. I later on use a dremel tool with a snake extension with a mini rounded brass brush to help break up any accumulated residual hard carbon deposits. I then use compressed air to blow out any carbon chunks and repeat the process one more time. The results are instant and unbelievable! You can do this with the head on the block. Use a combination of paper towels and compressed air to dry out the ports. Again, with respect to the Chemtool, I can soak a heavily carbonized piston head for 10 minutes, let it dry out and wire brush the carbon off. The carbon just flakes off with no problem!
Thanks
No problem
I would to see a video showing the before and after of the valves when doing this job.
You'd have to remove the intake plenum and manifold. A lot of work!
@@hardlymovingpro I understand, I just always wanted to see how Honda/Acura fair with their Direct Injected engines. We have several Honda/Acura products with DI engines (2014 Honda Accord & a 2017 Acura MDX). And so far they’re still running smooth with no loss of power.
Bmws/ VW have been direct injection for while now and they get really bad with the gunk built up on the valves to the point it’s causes miss fires and all kinds if problems. They actually recommend walnut blasting the valves every certain amount of miles. You have to remind the intake manifold and everything. But boy do they get a ton
Of build up.

@@MrSamPhoenixSame here. 2014 accord with 116,000 miles and smooth af.
Thank You!! Excellent Video!!
Glad it was helpful!
Great video, clearly explained everything that a child could understand…quick question though, why did you pull the brake booster on the mdx from the firewall vs the connection closer to the engine?
Thanks! More difficult to connect the spray tube to the intake plenum than from the vacuum hose that's attached to it.
@@hardlymovingpro great thank you. I tackled cleaning my MDX throttle body last weekend, might try this out this weekend lol I’ll let you know how it goes
Ok. Let us know how it work out!
I followed the procedure here for a 2013 Honda Accord, but my check engine light still remains on after the 10 minute drive. Any idea what could be wrong?
Do you have a cheap scan tool to reset the code? You can buy one for around $25. Or you can try disconnecting the battery for 30 minutes
@@hardlymovingpro Thanks. I disconnected the negative battery terminal for about 10 minutes and when reconnected all is clear. Appreciate the advice.
could you please show me a pictures were is the location of the vacuum line on hrv 2020 also can you do it alone? or is it a must do it with someone else? i saw a pedal depresser can hold the pedal to certain rpm? does this work please tell me also how many intervals doing this? best when changing oils? please replay i want to clean my valve also
Sorry...don't have a HRV to show pics.
Great info
Thanks for watching!
Great Video! Do you know if the 2012 version of the accord needs the same amount of attention to the fuel injection system? 5-10k seems pretty frequent and I had never heard of this problem. Either way, I m planning on doing this soon, but I m curious.
Thanks for your comments! I'd recommend doing the cleaning process every 10k miles. The PEA detergent will also help clean carbon deposits in your combustion chamber. Toyota's solution to the problem was to have dual injectors; that is one port and the other direct. When the port injectors are activated, the detergent in the fuel contacts and cleans the intake valves. Toyota also found that in certain driving situations, it's better to use the port injectors. I'll guess that most of Toyota's competitors will adopt using dual injectors ... assuming EV's don't take over the world.
@hardly moving productions hi I have a question. Do you need to do a oil change after the process of the CRC valves intake cleaner and fuel injectors cleaner? Thank you
I have a 2022 Acura MDX that I drive for a living. I bought it April 15th 2021 with 10 miles and now I have 97,000 miles as of December 22, 2023. Where would I do this on this engine? I can't find any documentation or videos because the car is so new. there is rough idle now. I've already added gum out multi tuneup to the fuel gas multiple times during the course of its aging. I always get to oil changes as required with full synthetic oil from the dealership. But nothing on the intake valves as it's not an easy thing. Thank you..
You're due for a water pump and timing belt replacement. I've dealt with Honda 3.5 V6's with similar idle issues. More than likely your timing belt is stretched.
Is this what my Honda dealership wants to do for $194? Fuel induction service for a 2020 Honda Accord EX-L
Yup!
Solid video!!!
Thanks!
Excellent video, do we know if this problem still there for latest GDI Honda or toyota vehicle
It's a fundamental problem for all GDI vehicles.
Could you make a video that explains how to get to the throttle body on that same model MDX?
Yes ... one day.
I just cleaned my throttle body on my 2012... It's very simple... Take the air filter hose off and it's right there leading into the engine. Just need to have the ignition ON but not running and the accelerator pressed down while doing it. Otherwise it won't open to clean the back side.
Has it been proven that carbon builds up on the intake valves from the ports on gdi engines?? All that goes through those ports is supposedly clean filtered air. How would carbon build up with just air??
I'd assume EGR gases being mixed into the air stream or residual gases backing into the intake manifold ports.
@@hardlymovingpro I didn’t think about that. That would make sense. Thanks for the great video.
You bet!
Is the Intake Valve and Turbo cleaner method recommended for a 2009 4-cyl Accord? and should it be sprayed directly into the fuel rail?
If it's a GDI (gasoline direct injection) engine, clean via the intake; if MPI (multi point injection) then via fuel rail if your have the hardware to connect a fuel cleaner canister to the fuel rail.
If you want to save on dielectric grease, just buy silicone faucet grease.
Not much price difference.
@@hardlymovingpro it's not a huge savings but I save $1.75 on 3oz from homedepot vs autozone.
@@meblake7359 I get mine from Walmart or AdvanceAuto online with a 20% discount.
@@hardlymovingpro Thanks. I will have to check advance auto and walmart.
What kind of pliers did you use to separate the intake hose?
What I used in the video are hose removal pliers. Here's the link: amzn.to/49ddsbo If the end of the hose has spring clamps, you can use this tool: amzn.to/3ukux41 If you want to grip the end of the hose to wiggle it off, use these tools: amzn.to/49ddsbo
Can you go threw the throttle body or intake tube after the maf sensor to clean the whole intake plent
I guess you could but your primary focus is to clean the intake valves. The plenum doesn't get carbon build up enough to cause restricted air flow.
@@hardlymovingpro I have Silverado and my plentnum is full of oil threw the pcv system
@@arealmaintenanceandrepairl1103 common problem with some Silverado's where the manufacturer did not put a oil baffle plate below the pcv. You may have to get a redesigned valve cover.
Will seafoam work the same. I have a 2016 accord it has the same engine as this one
If it has the chemical PEA which reacts to and dissolves carbon.
Some cars like the IS 350 have both GDI and port injection and so they don't have carbon buildup, I guess the accord sport only has GDI?
Dual injectors per cylinder is Toyota technology. Don't know if Honda is adopting or has the same tech.
only Lexus has it. Honda no.
@hardly moving productions Iam sorry sir for been asking you so many question but I am confused about the 2010 Acura MDX engines and may be you can help me to find the answer . Is the 2010 Acura MDX engine direct injection or indirect injections ? I was looking online but I couldn’t find anything about it . Thank you..
Believe last year of port injection was 2013
Would all of that carbon damage the catalytic converters?
Nope. The converter is like a mini furnace and should burn it all up. But an oil burning engine, on the other hand, can clog up a converter.
Can I use the CRC aerosol can ($15) method on a 2016 MDX or do I need to purchase the concentrate and mix with gasoline? Thank you!
You can do both for good measure.
I was thinking the same, I believe what is shown here is two different processes using PTA solvent to clean GDI engine.
One step you miss I don’t see on your video is, you should remove gas line fuse before you install the carbon cleaner and fuel cleaner line and run the vehicle under a certain RPM !!!limit!!!
Are you sure your post if for the right video? This video is for a GDI engine. I have another video for MPI. In the MPI, if you remove the fuel fuse the car won't run.
Whoaaa i thought it was gking to be easy
Pretty much.
Dielectric best friend 😂
You said it!
I thought it had to be sprayed down line of the check valve?
Anywhere where the spray solvent gets in the intake air stream. You could spray through the throttle body if you want.
Hardly Moving Productions yes, I go through a vacuum line unless I want to clean my throttle body too. I was wondering specifically about the check valve in the brake booster line.
@@6atlantis check valve opens in the direction of the vacuum.
Great videos! Question, what type of tool is that which you used to separate the brake booster hose off with?
Thanks! I use hose grip pliers. Here's a link to see what I mean: amzn.to/3Qz9pgC
@@hardlymovingpro Thanks for the reply, not those, it was more of a spreader type tool. 1:31 time frame in your video. Appreciate taking the time out to look at this.
This basically be the same thing is on the 2020 Civic?
If it's a GDI engine.
@@hardlymovingpro thanks man, oh and I just now saw how horrible my grammar was in my question.
Can I do this for my 2008 MDX?
Sure.
Wouldn't straight gasoline do the same thing? Since gasoline has detergents already in it.
Nope. No PEA in gasoline and the detergents are in low concentration.
@@hardlymovingpro I always put shell V power in my J35 .. is that better than regular ?
@@jason1234934 which J35? Honda Pilot makes no Difference for vpower, actually may Increase Carbon Buildup., Acura recommends premium, but I run mine on regular just fine. Its all about how the car feels.
Is this the same as using seafoam?
Seaform doesn't have the PEA chemical additive to breakdown carbon buildup.
Does anyone know if a 2004 Honda Pilot is a pfi or gdi?
04 is not a gdi.
@@hardlymovingpro How about a 2011 Honda accord?
is 2001 acura mdx works?
Don't believe it's GDI engine.
@hardly moving production hi I have a question do you need to do a oil change after the process with the CRC valve intake cleaner and fuel injector cleaner?
There could be mild oil contamination but don't believe a oil change is necessary. Best time to do this service is right before you do an oil change.
The instructions on the CRC can states to do this procedure just before an oil change.
I did this to my accord and now the check engine light won’t go away
Might have to get a code reader to reset the code.
HONDA is the new 90's HYUNDAI. I owned a 10th generation accord. Computer died at 33k, warranty ended at 36K, brakes went at 38K, then the big problem came at 58.6K FUEL INJECTOR FAILURE $1600 repair-must replace all 4!! Videos on my channel for all to see. Not covered under my warranty! Called Honda how could major part failure occur so early!!! Got ghosted! Dealerships so out of touch they recommended brake fluid replacement at 30K. Started researching and found out Earth Dream engines turn into Earth Nightmare engine: injector failure, oil dillution, turbo failure, cat converter failure start appearing @ 100k. By the time you see the signs all the dealers and influencers will be smiling down on you but helpful to sell you the newest version for a nice loss passed on to you. With almost identical engine I have no doubt the 11th Gen Accord will siphon your wallet turbo fashion after that joke of a 36k warranty runs out 😂
That's a crazy ownership experience story! Never, ever had a fuel injector failure experience. They do get dirty and can be cleaned.
Could also be dirty intake ports due to GDI carbon buildup.
@@hardlymovingpro I have a 10th generation Honda Accord and the fuel injectors, mainly getting very very dirty carbon buildup as a problem, so unless you can clean it, you will end up replacing all four fuel injectors at one time. Among other problems with the 10th generation, I would think twice before buying a Honda again.
As
What does this do to your catalytic converter? I would think doing this cleaning every 10K miles is slowly destroying the catalytic converter..expensive repair.
Nope. It's converter safe. The converter acts like a mini furnace burning off any residual unburnt fuel or combustible (i.e. valve cleaner).
