In this video I'll talk about how and where carbon buildup can happen on an engine with Direct Fuel Injection (GDI) or an engine with Port Fuel Injection. What are the symptoms of excessive carbon buildup and how you can diagnose and engine with carbon buildup, also how you can prevent carbon buildup and whether or not engine oil can effect this and last but not least how you can treat or remove carbon buildup from an engine.

Speaking of using water to de-carbon your engine, I think it would be worthwhile investigating. When I was a young bloke back in the late 60's early 70's there were a heap of aftermarket water injection kits on the market (of course everything was carbies back in those days). It was supposed to increase power but as with all these magic things the results were subjective. However, it is common knowledge that if you have a blown head gasket that's letting coolant (water based liquid) into the combustion chamber, when you take the head off it's easy to identify the cylinder that is affected because it is often quite clean compared to the rest especially if it had been leaking for a while. The water injection systems on the market 'back in the day' were simple and used a water container attached to an adjustable valve that fed a small venturi. The amount of water could be adjusted, and there was never enough to create a compression lock. So if you have a car that has serious carbon buildup it may be worth looking into.

@taneesescu Год назад

you can. they sell a mister fan with small tank (.25L). attach to air intake hose and set the fan on and let it do it's thing. Small doses come out and is continuous. I saw someone refill and do it 3 times while car runs. It won't do much for carbon buildup deposits.

@Z33Garage 3 года назад

Get a good recirculating oil catch can, And drain it as often as you need to. This will help greatly by condensation the vapors to liquids and trapping them in the can from going into your intake. Also change your PCV valves.

@applepoop10 3 года назад

I’ve always had success with Marvel Mystery Oil. I dump two bottles into my gas tank; it provides additional lubrication for the fuel pump, cleans the fuel injections, and it cleans up the pistons and combustion chambers. If I want a deep cleaning; I warm up the engine first and spray water mist directly into the intake. The steam from the water will also clean up the pistons; but you have to be careful not to dump too much water because it will hydrolock your engine and blow it up.

@stealthg35infiniti94 Год назад

@@Dudeman9339 I guess you are not familiar with manifold Injection cleaning. I've performed this service for over 20 years with no issues. You can either use the Seafoam spray with the long straw via the Throttle body or use the regular Seafoam bottle via a vacuum hose. Find a vacuum hose that goes to the manifold. Start engine and hold RPM near 2.5K with your helper. Now with the disconnected vacuum hose, S-L-O-W-L-Y pour the Seafoam. If you stalled the engine, you poured too fast. Re start the engine if you stalled it before adding any more. During this 10 or so minute process, you will see plenty of white smoke coming out of the tail pipe. Use the entire can and let the car idle for a minute or two and shut off for 15 minutes. Start car and let run for 5 minutes to burn any possible residual solvent. Now take the car for a safe "Spirited Drive" to again burn any more residual solvent. Don't be surprised of possible engine coughing during the drive. There are plenty examples on YT showing this entire process.

The other problem with using water to clean an engine not mentioned here is this: blow-by. You will end up with water in your crank case as if you had a blown head gasket, and probably more than you might expect too. I think Project Farm did a video on cleaning with water some time ago which revealed this problem.

Unless you have a heavy worn piston ring it's not a problem. The tiny amount of moister that may enter the crank case will be cooked out in no time. Moister will always work it's way in just do to condensation. The oil when at full running temp will heat up any water and it will evap out

@JazzyJonas 3 года назад

A piston soak is another great way to remove carbon, but again you have to be careful to get all the solvent and crud out before you fire up the engine to avoid hydro-lock (RIP engine) I just did a soak on my Matrix and literally removed a handful of carbon. My fuel trims went back to almost zero, my idle is perfect, and it cut my oil consumption by at least half :-)

Guys, pouring a little water down the carb slowly worked a treat back in the day, but to be fair, my engine was a 425 cu in V8 which wasn't likely to hydro-lock short of dumping in the whole can at once. I've got to think if you have a much smaller engine your margin for error is a whole lot slimmer. Plus with a cast iron intake manifold, I've got to think that a lot of the water was turned to steam before it got into the cylinders. I'm thinking with a plastic intake manifold you aren't making much steam before you hit the intake valves.

@rhollyday 3 года назад

Carbon in the intake is not caused by oil blowby around the piston rings. Blowby happens mostly in the other direction, fluids move from high pressure to low. Intake valve is closed during compression so blowby oil can't get up into the intake plenum and behind the valves. When intake valve is open, air is coming into the cylinder, so there's no way blowby can get into intake against the wind of intake air. Carbon deposits are actually caused by the PCV gases which are full of atomized oil from the crankcase which is full of oil, and crankshaft spinning to mix the oil into an oil fog. Crankcase pressure from piston ring blowby (in the other direction) combined with vacuum from the intake sucks the oil fog from crankcase into the intake via PCV valve and pipe. Catch-cans installed in the hose between PCV and intake will filter out most of the oil droplets and slow the accumulation of carbon on intake valves. Changing the oil regularly and using synthetic oil with higher burning temperature and less oil smoke in the crankcase slows the accumulation of carbon deposits in the intake.

Yep, I use the CRC cleaner as part of every oil change (about every 8000 miles) in my 2017 Honda Fit with the 1.5L direct injection engine. I also had a '91 chev cavalier that would regularly develop a knock due to combustion chamber buildup so I would drip about a pint of water into the intake of the running engine to create steam to blow out the carbon. Knock disappeared for about 3000-4000 miles until carbon built up again and I would repeat the process.

I have a easier ,better tried tested and proven solution for this problem. Turbofield Nano Treatment it is called . It treats the metal and not the liquids .

More power more mileage and long long engine life extended to hundreds of thousands of miles. Less friction heat noise vibration harshness wear and tear and low emissions as well . Immediate results.

A bottle of Techron Concentrate will be safer and give you better results. Just dump it in your tank at the right dosage and drive it normally. There are tons of good solid data sets on this. I used to do that testing. It will also clean your intake valves and ports and injectors. Dirty intake valves can cost you 5% on peak power, Techron Concentrate can restore it. Just dump it in your tank and give it a couple of weeks to work gently and steadily. It's good stuff. One bottle should be good enough, but if there are any questions, just repeat and put in another bottle.

Any direct injection engine should have an oil separating catch can inline for the vent. It traps water, fuel, and oil from being vacuumed. Maybe not all of it but enough of it that the valves stay cleaner longer. Even with port injection the oil separator helps keep the throttle body cleaner longer.

You don't need a expensive one you can find lesser expensive on eBay.

@3:56 Those are Toyoda's engines with direct and port injection like Those in the GT86, the Lexus IS 350 or Toyoda Crown Athlete GRS 184. :)

BG makes a good product to clean valves. You can also use oven cleaner if you pull the intake manifold and apply directly. Its not too hard.

@Game-Over-U-Tube 3 года назад

Maybe if you have a really old vehicle. Anything 1980s and newer is gonna be a bitch to pull the intake, just to spray some carbon cleaner

years ago Popular Mechanic Magzine showed how to make a device that vaporized water and injected it into the carborator thru the vacuum hose. It increased miles per gallon and the water vapor cleaned the cylinders and combustion chambers. I installed on and my spark plugs looked like new after 6 months and I got 3 more miles per gallon. It cost about 5 dollars to make. Why doesnpt car manufactures install something like this. This was in 1970's

If you want to help a group of people, create a video on cleaning the intake ports/valves of any turbocharged, GDI Honda engine, such as the Civic Type R, the Accord turbo, the Civic Si, etc. I have an FK8 Type R and it sucks for doing this. There is zero realistic access for the injection of the cleaner. Thank you!

Use to re-route a windshield washer hose to a vacuum port. Hit the washer a few times while driving and watch the carbon blow out in the rear view mirror.

I wanna see what my cylinders/valves look like after using WMI for the last year and a half...

I just pulled the Head on my 1993 Accord with 290K miles on it. I took me 6 hours to get all the carbon off the top of the pistons. I bought the car used with 160k to use for a work car. The first owner did not use quality Gas or oil. I am going to finish putting it back together tomorrow and am very curious about the results of my efforts.

@livingstone2k1 3 года назад

Great video. What are your thoughts on using an OCC on GDI engines to prevent carbon buildup?

@cryptoanalysts5793 3 года назад

1 qt of transmission fluid drive 200 mile , change your oil , and it will be 100% carbon free

Yeah clean engine but now it knocks

Cool I traded a little carbon buildup for a blown piston ring and warped bearings. Epic

m valentino karma is bitch , I traded a ford sport trac , transmission was slipping I added some transmission slip Lucas and got 2007 Toyota RAV4 thinking 🤔 I was smart , guess what , the car burn a qt of oil every week Need a catalytic and new spark ⚡️ plugs Wish if I kept that ford

a lot of reviews say that seafoam doesnt work... can you talk about that?

@MustangGuru 3 года назад

Carbon build up be so bad that the engine Diesels due to carbon glows hot and ignites the gas before the spark plug fires.

excellent explanation of how everything works in an engine. Really appreciated, thanx :)

Did you know the Rover V8 was originally a Buick design dating back to 1960 and was installed in Buick, Olds and Pontiac?

@Fa5Squad 2 года назад

Its from using crappy fuel and not changing your oil on time. An engine that runs good fuel and has it’s oil changed often will have fairly low carbon build up

Seafoam is for 2 stroke engines, not modern 4 stroke engines.

Hey man, I just bought a 2011 Ford Crown Victoria Police Interceptor with 107k miles and 6,400 idle hours. The car runs and drives great. It idles a teeny bit rough in park or neutral. It doesn't leak/burn any fluids. The only issues I've had was replacing the thermostat which was cheap and easy. Unlike most used cop cars this car's paint is still shines like new with a few expected chips and scratches. I paid nearly $5,000 for this car. Do you think I got screwed?
