How to clean intake valves on Direct/Indirect injection engines without REMOVING anything / ALIMECH

[@adilismit2822]

I wish I watched this amazing tutorial before I used the carb Cleaner on my rough idling engine last week. I sprayed through the throttle, black stuff came out, the engine was NOT running. I waited 15 minutes, then started the engine, was rough first minute, turned perfect after, I think I was lucky. The video instructions make more sense. Next time, thank you master Ali

[@AliMECH]

Thanks for watching, I have so many videos how to use cleaners without damaging anything

[@RS-dc7wy]

Excellent demonstration with before and after pictures, nicely done! Something else to consider when purchasing any Direct Injection vehicle is installing a "catch can" to prevent most of the carbon buildup on intake valves.

[@AliMECH]

Thanks, already got the catch can, I showed on my last video, I will install it soon and show how it will keep the valves and piston clean

[@sansarkawt3351]

@@AliMECH i dont get it there is supposed to be no carbon build since multiport injection yet there is quite alot why?

[@psions555]

carbon builds up in both MPI and GDI but with GDI it's far greater problem. It builds up on MPIs due to poor quality fuel, poor combustion or mixture etc. one of the main things is that the high compression of a GDI causes much higher cylinder head temperatures. The carbon not only applies in a greater volume but is then "baked" on. If you had GDI carbon buildup to the same amount of carbon on an MPI it would be much more treatable and more likely to dissolve in a safe way on MPI, Any cleaner or additive isn't going to go past the intake valve on GDI. The baking of carbon on GDIs can cause chunks of carbon to dislodge that are large enough to cause damage to the cylinder, valves, turbocharger or go through to the catalyst and burn up fierce. @@sansarkawt3351

[@Keith-e5f]

​@sansarkawt3351 because it's GDI only. Meaning that there is no fuel being injected into the throttle body so there's no way the back of the intake valves can be cleaned with a GDI only motor. Other GDI Motors also have fuel injection in the throttle body which cleans the intake valves constantly.

[@lektroniq4962]

Fantastic. Your tutorial helped me. My car used to be vibrating roughly when I used the air-condition for long times. After I followed your tutorial no more rough vibration. Engine running supper smooth. Running 6000+km and counting 😃😃

[@AliMECH]

Great to hear! And thanks for your feedback

[@EricJones1969]

Hey! Tried your method today. That is awesome and really working! I bought a used car, no history about how previous owner used it. (My thoughts are home-shop/work-home) It has a broken and clogged up PCV valve, which we changed. But the engine still got a rattling noise. It's gone now! It's working much quieter. I do believe that was gunk around valves and pistons which is gone by now! So thanks to you a lot! PS By the way, came here after Scotty's of ChrisFix comment section. (Do not remember exactly) Cheers from Russia, bro 👍

Thanks, glad that it worked for you 🙏🏻🙏🏻 Russian 🙏🏻🙏🏻

I'm starting to suspect that this might be my issue on my GDI, some major Carbon build up on my valves. I changed my plugs and plug wires, cleaned the throttle body out and it still runs a bit rough on/off during idle. Feels like the torque power isn't there when accelerating.

I'm a bit confused but I used to disconnect brake booster on fuel injected vehicles to spray cleaners or pour cleaners in. In your video says pcv hose is that the same hose but not removing it?

[@AliMECH]

Thanks, I'm close to camera, what u means exactly lol

[@thegoldeneagle6818]

Greetings. What about the catalytic converter? Will carbon deposits stick to it or not?

[@cometcal2]

To prevent deposits from clogging the converter, you have to remove the intake manifold in your direct injection engine and manually clean off the valve deposits. Be sure to make sure both intake and exhaust valves are closed in each cylinder.

[@deecampbell1005]

Thanks for the video, can I use seafoam instead through the pcv hose for my turbo gdi car?

[@bankfishermantv7801]

Where would you spray this if you have a electronics throttle body

[@KashifJavedForex]

What if I see some engine oil on the valves along with carbon build up? My car has misfire issue. I tried to solve by changing injectors, plugs and some other tweaks but nothing helped. cylinder 3 has more misfires than others and it has more oil on the intake valve. So you think this is the main cause of the misfires? And this oil means stem seals needs to be change?

HI Ali, my car has a maf before the throttle body and a map on top of the intake manifolf after the throttle body. The pcv valve connected to intake manifold is close to the map sensor. Will this damage the map sensor, if i use the pcv valve outlet in the intake?

[@jcberb]

My vehicle has a similar setup, my assumption on this based on how the PCV and intake works is that what your spraying into the manifold is being ingested by the engine due to the the crank case pushing air through the PCV into the manifold and the manifold taking in air from the throttle body. Seems like the direction of travel would be away from the sensors.

Sir, is there any possibility of carbon removed from valves would clogged the catalyctic converter and oxygen sensors?

[@bt4308]

I doubt it would. The carb cleaner dissolves the carbon build-up, and then it's combusted and shot out the exhaust as vapor and smoke. And whatever carbon is left on the cat will burn away once you take it for a drive. Cat's clog up when they melt from running the engine running too rich or too lean, or from certain fuel additives like over-the-counter octane booster.
