WOW! I just did this for the first time on my 2014 Honda Accord after getting a check engine light at 175,000 miles. The engine light diagnostic showed Error Code P0087: Fuel Rail/System Pressure Too Low. I thought it might be the fuel pump which would’ve been around $1500 to fix. So before doing that, i changed the air filter and used the CRC GDI Intake Valve & Turbo Cleaner and i must say I’m extremely happy! Not only did the engine light go off and i saved myself a lot of money, but after about the second day as this cleaner continued to work it’s magic, my Honda is running like she’s in her early 20s again! I highly recommend treating your car with this! Thanks for this video!!!

[@hypnoticimage9687]

I wish I saw your comment before I change the high pressure fuel pump but didn’t pay that much $150 on eBay for the part and about $250 on labor at the shop.

[@jamesayers1770]

Thank for sharing I watch another video and this guy took his whole intake apart and I was hoping there was a simpler way thank you

Hi Russel, I've been looking to clean my 2015 Hyundai Santa Fe XL engine with this CRC formula. After looking at several videos, I believed yours to be the best with that closed to vacuum tube system directly into the engine, just like you did. Just came back from doing it now and it worked wonderfully, no check engine lights at all. Some smoke at first after the one hour wait but it now does idle silk smooth. Thanks a lot for your video! Thums up!

[@lalajee143]

Update: Technical Support Team at CRC tells me that they can't guarantee that the product will be properly atomized if the hose extension is longer than 6 inches. They recommend directly spraying the product into the vacuum port.

I was wondering that as I could see a build up of fluid in that tube as he was spraying. I have a 10th gen and I think I’ll take the pcv hose off the intake side by my catch can and have someone spray directly into the nipple while I keep revs up👍🏼

[@rudyruiz9615]

did the same cleaning on my 07 cooper "S" (turbo) it went from crappy mileage and rough idle to smooth idle and 10% better mileage.

[@ospuddy]

Thank you for the video. I cleaned my intake valve using your method. I made one minor modification to your formula: I use a hose with a smaller inner diameter (2mm) just large enough so the straw can fit in the hose and adapted the hose end to the diameter of the vacuum port. If the hose diameter is too large, the liquid will lose its capillary action. A fun fact of using the hose is that the hose gets cold as you spray due to the expansion of the liquid (similar to the evaporator mechanism of a refrigerator). I also got the check engine light after this procedure, and the car limped along for a block billowing blue smoke, but the CEL turned off after a few restarts and the engine is running smoothly now. I appreciate you posting this video.

Genius move using the vacuum system

[@iaintempl8]

Carb cleaner worked great on my 2012 mazda 6 2.0. Fully warmed up the engine and held the rpm at 2500, sprayed the full can in short bursts to prevent stalling. Engine is much smoother and fuel consumption is a lot better.

[@W0LV1E45]

did it smoke? I use carb cleaner on my veloster and no smoke. I drive mine hard so that might have helped with carbon not building up.

[@iaintempl8]

I had the same warning lights come on as well. Blinking engine light, electric steering , tpms. I used sea foam thru the throttle body though. Same affect, car does run better after it self corrects itself. I ran it hard for 10 minutes then parked it and shut it off. Upon re starting everything cleared out.

[@fkutb]

Exactly what I needed. Thank you!

[@biz4twobiz463]

Recently did this procedure on a 2016 Honda Pilot 2wd Touring. Went in at air cleaner just past MAF sensor. After the one hour heat soak, took for 10 min drive per instructions. All the Honda sensors light up like a Christmas Tree!! Had to use a INNOVA 3130 scanner to delete any codes. Not once, but twice!! LOL!! After that, the Pilot has been running fantastic and the idle is SUPER smooth. Did it around 70,800'ish Km. Enjoyed your video!! Merci!!

I appreciate your generosity and public service. Has anyone ever used this product/ technique, and then pulled the heads to note the effectiveness on the valves??? My worry is overheating or poisoning my catalytic converter`s catalyst. How much danger is there for this?? what is best is hybrid direct AND port injection...... but it is expensive, and car manufacturers are competitive......and greedy. I have a 14 Kia Cadenza, direct injection with 27K. And I feel a very slight decrease in smoothness and responsiveness from new. Let me know, MJM

Good idea to replace Oil after this cleaning. Oil is contaminated with unburned cleaner.

Correct, it’s a good idea to do this prior to your oil change. These chemicals can be hard on your internal engine seals which may cause engine leaks.

[@robertklein7679]

Russel, great video but if you think of the wind currents in the intake and then induce fluid to it by way of the brake booster inlet please take a look at where that is on the manifold and you will see it will only favor the closer ports, the majority of fluid will be abundant on some of the valves an very little to some and maybe not even a drop of fluid will even reach some of the valves this system would only partially work if only the manufacturer would put the booster inlet immediate after the Throttle Body or Carburetor. Also, these products only work when they end up being vaporized, Please try this take the other end of your hose off the engine and then spray the aerosol and you will see it will only come out as a liquid not vaporized. Therefore you will only get a steady stream flowing on the inside of the manifold to only a couple of the valves. Thanks

[@SevenPageLetter]

Robert Klein I agree with your logic. Is there a vacuum line port/nipple on this Accord that you would recommend seafoaming?

[@Rickbearcat]

I've seen this product sprayed directly onto the intake valves of a BMW 6-cylinder engine. With both valves closed, he formed a liquid puddle on the intake side of the valves. This product does not need to be vaporized to work. Just the opposite in fact. It has to be and remain in a liquid state to coat and penetrate the carbon deposits for full effect. kzbin.info/www/bejne/gZ-Zf4l-gd5gjsU

[@TheOzthewiz]

Well, when all was said and done, his engine ran SMOOTHER and STRONGER after the procedure! Obviously the cleaner did what it was supposed to do. I'm convinced!!

[@marxseet]

Might not be so depending on design of the manifold distribution pattern, because if that happened to the cleaning foam, this will also happen to the air distribution during normal drive. I think the new generation of car should have overcome this issue.

[@DIYAutoworksNG]

@@marxseet You definitely have a point. Though since liquid is heavier than air, it could be plausible to have the cleaner gravitate towards the closer ports. I intend to do this but with before and after shots of the intake valves...

[@chrispolk8919]

Russel, I just bought a 2018 Tucson form a rental car agency with 35k mile. I reschered the GDI engine and the valve build up keep showing up. I didn't know the mantaines history of the car so I tried the CRC intake valve clean. I followed the video step by step but, I had to periodically allow some air in to the line so the CRC could be vacuumed in to the engine. Other than that it worked great! It is just about done heat soaking. I will update when test drive it.

[@chrispolk8919]

Just finished the test drive & on cue when I hit the accelerator a lot of blue smoke came out the tailpipe LOL it made everyone behind me slow down. My Tucson has more power when ECO mode, run smoother & quitier. Thanks for the video!

[@stealthg35infiniti94]

I do the same procedure but instead I use Sea Foam with good results both on GDI and Port Injection engines...It will bring a high mileage car back to life...Doing this every 15k miles should prevent expensive walnut valve cleaning in the future...If you wait until you have the problem, one cleaning session will not clean up the problem...Several attempts will have to be made and then if permanent damage has not been made already.

[@pietsee1000]

Morriosn Jim Cleaning the throttle body is different Never do this to your gdi engine When carbon falls of your intake valve it will scratch or scour your cylinder walls Which would result in loss of compression and could start oil consumption And you could even damage your catalytic converter.

[@denztl]

I am going to use the CRC Cleaner on my Ecoboost Mustang when I get a few more miles on it, now at 3000. I believe the cleaner should be injected into a central location before the intake manifold divides up to go to the individual cylinders. The vacuum port you are using is likely favoring one or two runners on the manifold and therefore not getting even distribution of the cleaner to all intake valves. There are numerous videos here on KZbin showing this phenomenon and how oil from the PCV line will coat certain valves more that others . Also I saw a CRC video that indicated injecting the cleaner after the sensors at the throttle valve.

[@denztl]

[@Sagina1999]

Truth

[@pietsee1000]

Seafoam, BG, CRC, X66P, etc. are all basically the same make up. Ford has release bulletins that is will void warranty on any ford GDI engines, if you do this treatment to your gdi engine. These are safe with carbureted or port injection engines as the coking deposits are the "soft carbon" and very little to loosen and expel. GDI engines the valves run far hotter with no fuel touching them any longer to cool and clean them, so when used, these absorb into the deposits causing them to swell and expand and break loose a portion and most is then expelled out the exhaust where it makes contact with the catalytic converters and clog's and/or causes damage from the cooling shock of this solvent hitting the catalyst honey comb material when it is up to temp. The real damage though is from the smaller particles forced down between the pistons and cylinder walls as it can be as hard and abrasive as sand. That is never good as the scratches/scouring left allows even greater blow-by and oil consumption. We also see a high incidence of rod bearings failing shortly afterwards if oil and filter are not immediately changed to remove the solvent and particulate matter forced into the crankcase. Now on port injection engines, these have been and can be used safely, but they do not have intake valve coking issues like GDI engines.

[@richardbudd5334]

He's doing this on a 4 cylinder engine. Completely different manifold from a V8

[@G9Classified9]

Did you rev engine 3 to 4 times after can was empty and if you did reattach the vacuum hose or did you leave it connected to can ??

[@stevie5484]

This question may have been asked, but it seems the cleaner will not be equally applied to all the valves, so only the valves closest to the vacuum hose will get most of the cleaner. Thus, the air intake may be a better option. Thoughts?

[@liquidh5226]

Do it both through the brake booster line and also the air intake throttle. Do clean your air intake throttle first. I plan to do this.

You can walnut blast the valves without removing the head, just the intake.

Great video. We have a 2015 Mazda 3 and a 2015 Honda Fit both with GDI engines and I plan to do the same CRC treatment to both of them. My main concern is picking the right engine hose to disconnect and attach the clear hose with the plunger to. What should I look for in the many engine hoses attached to the engine to be sure I'm pulling off the right one to attach the clear one to so the cleaner will be sprayed on to the valves? Also, do you use up the entire can of cleaner per use? Thanks.

[@9thGenAccord]

Daniel Diaz that sounds about right when mine did that. I was able to find one on eBay used with 5,000 miles. The guy said he had totaled it. I have almost 200,000 miles on mine now and it’s running great. I recommend using ngk spark plugs though. I wouldn’t take the chance with the off brands.

[@DanielDiaz-te6dl]

2 THESSALONIANS 2:10 brother thanks a lot I definitely going to buy that part.

[@anders949494]

dont the engine need to be fully warmed up before spraying the cleaner?

[@9thGenAccord]

Yes it does and the engine was up to operating temp.

[@MegaHollywood1971]

9th Gen Accord That was not explained in your procedure.

[@9thGenAccord]

Hopefully one will actually read the directions on the can and will follow them.

[@ChickenC0re]

You have too much faith in humanity. LOL

[@sk8allica1]

@@ChickenC0re He did an effort to help... lets be well educated and mannered and be thankful please

[@TaintedMojo]

Does this work if you have a turbo though?

[@Japplesnap]

Unless you have seen the before and after on the intake valves, how do you know that this is effective? My buddy tried this on his Accord and the intake valves still looked pretty much the same, so he ended up doing walnut blasting on them. That's the only method that got his intake valves completely clean.

[@GIZZMOTORSPORTS]

Also cant be great for the piston rings, o2 sensors, and cat conv. This GDI junk is a horrible mistake.

[@frankm5019]

the best method is getting a port injected car and stay away from this gdi garbage. you can destroy your engine ,with this method...

[@Japplesnap]

@@GIZZMOTORSPORTS I disagree. Direct Injection has good benefits. But it does require more maintenance. It's not that bad though....most cars are just fine with a valve cleaning every 50,000 miles or so.

[@Japplesnap]

@@frankm5019 Very few cars are port injection anymore. It's older technology.

[@GIZZMOTORSPORTS]

@@Japplesnap You have to admit the bad is much worse than the good. I can't see many doing preventative repairs, they will wait until their dash is lit up. By that point it's too late, some will run a chemical cleaner but at what cost?

[@ilovemywifemost]

Very interesting video and it seems like a great idea, especially for convenience of discharging the cleaner from the driver's seat. I was wondering if injecting the intake valve cleaner into the manifold through the brake vacuum hose is as effective as from the air filter side. My concern is that the cleaner might reach all the cylinders better through the air cleaner than through the manifold vacuum port. I am not sure how to tell the difference in effectiveness. Maybe a mechanic could chime in on this.

[@frankdesimone7569]

>k.

[@JGBecknell]

1000 RPMs seems kind of high at a stop. Is that what it should be? Is it smoother at 1000 RPMs?

[@derfstang480]

Thumbs up for the video and effort. These products work best as a preventative measure as you mentioned. Like every second or third oil change. Once the carbon is built up enough to trip the CEL for a misfire, it’s game over. Walnut shell blasting is the only “easy” fix to remove that level of carbon. Been there, done that with the notorious VW 2.0L Tsi motor.

[@noliuntalan5314]

how much doing walnut shell blasting? this procedure is the safest to clean a direct injected engine.

[@ivanbulgarin7232]

I need to ask what happens with the carbon valve deposits , also can we see the valve before and after

[@-MrRichBiker1967]

They go into the bottom of the engine that's why you have to change your oil

[@ronmartin4320]

Some of the carbon mixes with the oil and some goes out the exhaust, that is why you see the white smoke when using carbon cleaners.

[@tpm1868]

I noticed that your idle is around 700-800. My 2014 6sp Accord idles at 200. Is yours idling a little higher because you just used the CRC cleaner?

[@candesearl]

It would be good to change the oil right after this process to get any contamination out.

[@rm-zn9yh]

I have a 9th gen at 175,000 miles, can i still do this to my EX?

[@veasnayong3456]

Can I'm use on 2018 accord 1.5t?

[@SCUBA_5teve]

Any idea how to do this on a ‘17 Accord Hybrid? You cannot “rev” the engine like a normal car. Plus there is no tachometer.

[@TheOzthewiz]

The hybrid does not use a GDI engine, an Atkinson cycle engine is used instead!

[@dabell12]

Hello: I also recommend you after extensive work that you did, also that you should clean or change PCV valve [17130-5A2-A01]. It should be remembered that PCV valve is the one that keeps pollutants out of the engine and the catalytic converter. if that valve [ PCV ] is not clean or working properly the contaminants end up in the intake manifold and then in the catalytic converter. nice video, good look

[@ohboy2592]

Umm, that’s not how a pcv system works. The purpose of the pcv is to take those contaminants and put them in the intake to burn through the combustion process again making them less toxic for the environment. Positive crankcase ventilation, taking unburnt vapors and relieving pressure from the crankcase and ingesting them back into the engine. You are correct in you should clean or just replace if it’s easy access often.

[@BrianHer530]

I have a 5th Gen CR-V and where should I put it...

[@BW-kv9wj]

Did you spray the whole can into the hose? Once it’s empty, how long do you idle it for?

[@unclebean8367]

The answer you're looking for, is already written in the product can.

[@ETangooo]

Hi, what are you thoughts are spirited driving like almost redlining your car to help burnt he carbon deposit off?

[@9thGenAccord]

Sure its good but wont burn off the goop on the back of the intake valve.

[@jameskoralewski3583]

Not a bad idea to help burn off the carbon, but a very bad idea to destroy your engine or get a lot of speeding tickets.

[@thatmexicanguy89]

How long did you buy the hose and what is the diameter ?

[@davemc3650]

And replace cat in a few year later. Cat won’t burn away solid or when get dumped, it clog up and will trigger cat code sooner or later. Many shops upscales intake clean services or three step clean cars always have this problem

[@mattbova1138]

This stuff liquifies the carbon on the valves then is burned off in the combustion chamber , some of this unburned liquid will get into the oil then filtered out. It doesnt break off chunks and suck them out of the exhaust valves to get stuck in the cat....

[@odinsonthorhammer1]

What is heat soak?
