[@BlatentlyFakeName]

Yea tbh anything strong enough to remove it might cause damage to other parts of the engine (like seals). It's best to leave it unless it actually becomes an issue. I have removed light carbon buildup from a throttlebody using electrical contact cleaner. But it also needs scrubbing, which you can't really do inside the engine. Plus you don't want chunks of carbon falling in to the engine itself.

[@jumpr2134]

@@BlatentlyFakeName Actually you can sandblast the valves just by taking the intake manifold off.... using crushed walnut as the media not actual sand grain. It’s called walnut blasting technically. All you have to do is make sure the valves are closed for the given cylinder and blast away. It’s what the main shops do for carbon cleaning on intake valves. It really works fantastically well. Look up vids of it.

[@NordicDan]

The reason the intake runners and valves are this nasty in the first place is sludge and oil coming in through the PCV combined with sooty exhaust gas from the EGR. Eliminate that once they're clean and you'll rarely have to worry about that. With smog testing going bye bye in America (yay!) you can easily do an EGR delete which will in most cases help the engine actually run better overall, and there are several different PCV catch cans on the market that are inexpensive and easy to mount, or you can easily build your own. I built my own about 15 years ago and it has worked wonders. The only caveat is that you have to periodically empty them as they collect oil, and if you have more blowby than normal (my engine has 300K miles on it so that's the case with me) you have to be on top of monitoring it. Mine has a clear bowl that I marked with for a maximum level, so I can easily look and see when it has to be emptied.

[@johannjohann6523]

Totally agree. I don't think the small amount of "fumes" released into the air is much to be concerned amount compared to the exhaust and burning fuel. Best thing you can do for your car in my opinion. The PCV valve is an EPS mandated product,not something that was designed to make your car run better, or longer. ctually, just the opposite, which manyfacturers are certainly not going to complain about. In fact, we have the tech to build motors that can easily o 500K miles or more, but don't because then nobody would need a new car every year. lol. But that's okay. Understand, many jobs in the economy are there and created so people actually work to get a check instead of sit at home and get one. Or maybe not. An economy is a man made concept.

[@bwdz75]

Nothing works and that won't work either. Yesterday I was rebuilding a Kia engine and I had the head off, filled the intake ports full of CRC and let them sit over night, at best it got 20% cleaner when I blew it out with air. I tried sticking a bottle brush in there and loosening it up and that helped. Since I was installing new valve seals anyway I just pulled the valves out and cleaned them as NOTHING will get them clean save for blasting with the intake off. Now, if you regularly used a cleaner like this say every other oil change that might keep them from getting real bad.

[@jcwoods2311]

@@djyul You are a moron. You risk great damage by filling up a cylinder with the cleaner seeping past an unseated valve, only a 10% volume of liquid in the cylinder would result in a bent connecting rod at the very least. Crank the motor with an uncompressable liquid and you just did tremendous damage. If you bother to take off the intake manifold follow procedure and use a media blaster to get the coke off and clean the residu before moving to the next intake valve set. Obviously, your little knowledge IS a dangerous thing.

Older toyota engines only have the direct injection. But some of them don't have EGR which is a good thing. EGR is the main source of input port and valve soiling.

[@Penskeeee]

It's better to perform Walnut blasting every 60k km / 35k miles because with these cleaners, the built up carbon that were dislodged will be running through your cylinders and exhaust and could cause serious damage to your cylinders and/or cat converters.

[@thegrimreaper7777]

Try soda blasting (bicarbonate of soda in a sandblaster) it works great for taking carbon off without damaging the underlying material, if you can keep it dry you can vacuum the residue out, or it will dissolve in water so it can be washed off.

[@TrailVapor]

Mannol intake can work, I've tested it, but it melts plastic so should not be used with plastic rocker covers or possibly intake air tubes. Important to follow the instructions unambiguously ;) to avoid plastic parts exposure.

[@videomaniac108]

When I had a Ford Focus ZX3 I would run a double concentration(2 oz per gallon) of Redline SI-1 fuel system cleaner through a tank of gas just before the oil change. I would drive the car up a long steep mountain grade at highway speed to saturate the carbon deposits with the cleaner then park the car and let it heat soak for about 30 min. After that I would restart the car bring up the temp and then blip the throttle between idle and 3k rpm with the car stationary. I would watch the clouds of vapor and carbon in the exhaust and continue blipping the gas until the exhaust cleared. After a few sessions of this over a few days the carbon would no longer show in the exhaust and my engine would be idling more smoothly and pulling more strongly on acceleration, plus my cold start running would be better.

If EV's are being charged by generators (without a catalytic converter) then I'd say removing the PVCV valve and replacing with an oil catch can should be fine as well. And the best idea of all as it eliminates carbon buildup on the intake and valves the PCV system creates. How is burning and blowing that carbon out with toxic chemicals any better 4 environment?

[@mullerandre95]

In the old days when cars still used carburetors we just used brake fluid to clean the carb and intake side of the engine. The intake of this motor looks like it'll need a soak to get all that gunk off.

[@hpt08]

Mannol intake cleaner is 50-70% acetone so keep a few cans handy after using seafoam. The carbon released can clog your cat and the acetone in this clears it. Maybe try spraying it directly into the intake and leave to soak?

[@NATESINTERACTIVEAUTO]

I allowed a heat soak what other cleaners can we try?

[@hpt08]

@@NATESINTERACTIVEAUTO I think this mannol cleaner would be better if applied with the plastic wand. Maybe try atf too?

Never buy a car with a GDI engine. Should be outlawed.

[@victorgirouard1543]

Gdi is awsome tech running a good fully synthetic oil and change it on time can avoid this problem all toghter

[@Arsya_AR94]

Combining gdi with mpi should allow the best of both worlds tho

[@aldoavina7420]

just use premium fuel and you will reduce the carbon deposit, only reduce because it is inevitable to get gunk on gdi

First valve before 0:50 First valve after 4:50 Check these time stamps and come to your own conclusion if Mannol is great for caked up intake valves.

[@EXOVCDS]

The images were not from this engine... there is NO way that he can get a borescope that close to the valves with the manifold on and there is NOOOOO way that the valve position could end up in the SAME position "after" the engine was run. He is scamming all his viewers and giving the industry & other KZbin Creators a bad name!

[@froggy0162]

Direct inject is yet another good argument for electric cars...

I have a catch can I'm about to install. Wondering if it's even worth the effort after seeing this.

[@TangDynasty1983]

Thanks for the video. So you already had the oil catch can installed?

[@infotechsailor]

Ya I wanna know how long has he had the catch can on that engine. Since new?

[@akostadinov]

Where did you put the borescope camera to observe that valves? Can you show this in a video?

[@rasch19785]

You get much less carbon build up with fully synthetic oils, especially the low ash ones

[@courtneypope8979]

rasch19785 please explain what oil have to do with it (no being a jerk, just really don’t know) ??? Thanks

[@garrettbundy1810]

@@courtneypope8979 a big reason for carbon build up is due to blow-by around the piston rings., creating pressure in the crank case, which is released by a value, which then goes into the intake manifold. When that happens oil mist also makes its way through the value, causing the build up on the intake values and manifold

[@carlo264]

The best product that I use and is a 100%. Effective is stray diesel from the gas station. You get 3 gallon of diesel empty the oil out of your car. Then, you put the diesel inside for replacing the oil in your engine. Start your car for 20 minutes. Ravin up the ingine to 3000 RPM repeat this step 3 times and you will see the big difference in sounds and cleaning in your motor engine a did fixs my issues and clean my engine and only cost me $10 dollars

[@adama5392]

Spray a 50 50 mix of atf and acetone in there or mix a little kerosene with it and spray it in on the dirty valves.. Bet it will break down the carbon.. Use a valve stem and put it in the spray bottle if u want...it will work better than what you are buying

[@NATESINTERACTIVEAUTO]

What about stp and thanks for the idea

[@joeyng919]

What's the procedure though..? Spray through the throttle body? While running? Rpm, etc? And how much to spray?

[@NATESINTERACTIVEAUTO]

Same as crc 2500 rpm throttle body or intake vacuum

[@hpt08]

Mannol is mostly acetone so if he sprays it onto the valves it should work.

[@greggb1416]

Every GDI engine manufactured should come with a lifetime supply of this type of stuff, to be applied on a daily/weekly/monthly basis…, (whatever is recommended), on the lines of DEF fluid in the modern diesel engines.

[@surplussean3364]

No way I'd ever put water in a combustion chamber. Hydro lock

[@Arsya_AR94]

Thin mist could evaporate, but don't just pour a gallon of water there. I think the most maximum amount of water the engine could take should be less than the maximum cc of the combustion chamber, though it would stall the engine but i think it shouldn't kill the engine.

My grandpa always used a product called "RISLONE" he would get the engine up to operating temp and drizzle enough "In the intake" to about kill the motor then a good shot to kill it and let it cool overnight. Seemed to work well, The old scout 80 spat out a load of crap and smoked for a bit but it surely smoothed out and quieted down. Try it for yourselves.
