VdellaV posted a topic in 2014 - 2018 Chevy Silverado & GMC SierraHello Everyone After a few months of research and practical tests, I'm happy to announce that I found the chemical solution to remove Intake carbon deposits on Direct Injection engines. Im pretty sure many of you already knew this, but as I researched the topic, I didn't find any widespread info detailing what im presenting in this video. I had been using CRC GDI Intake Valve Cleaner for some time, and have had very good results, but I haven't found it in part stores anymore (I Live in Mexico), so this pushed me to investigate what the active ingredient on that product is: PolyEtherAmines (PEAs for short). I also found that you can find PEAs and similar carbon murdering detergents in most Fuel Injector Cleaner Additives. ** Its important to note that using a gasoline additive won't help in Direct Injection Engines, since the injector is inside of the cylinder/chamber ** So I got the idea of using Fuel Injector Cleaner Directly into the intake of the engine, like if it was seafoam, to get the PEAs directly to the carbon in the intake Runners and Valves. I have been using this method to clean the engine in my 2015 Silverado, which is a GDI L83 Gen V 5.3, and have retained the Fuel Economy and Performance like the truck was new. Im also running a Crankcase Scavenging System to vent all the PCV gasses to the exhaust to avoid any source of Carbon Soot going my intake, but that's a story for another day. Ill leave a more detailed TL:DR version in the video below. If you find it to be helpful please give It a big thumbs up and share. I greatly appreciate subscriptions to my YouTube Channel !
Hello Everyone As many of you know, GDI engines are more widespread than ever, and with them, regardless of how well maintained they are, they always develop Carbon Buildup on the Intake Valves and Runners, specially TurboCharged engines, and with mileage as low as 30k. Before having a GM Truck, I used to have a VW Jetta and rolled with many friends with GDI TFSI engines, so I know this problem first hand. The most obvious sign of Carbon Buildup is decreased performance and fuel economy, along with difficulty to star the engine or even knock under load. What I have been doing to avoid this problem early on in my cars is to bypass the PCV gasses to an atmospheric catch can or most recently to a Crankcase Scavenging System directed to my Exhaust, so the is absolutely no source of carbon going inside of my intake, but I understand this may not be a viable solution for everyone, so I would like to present another alternative: chemical prevention. Every 6k miles, as part of my oil Changing interval, I also replace the Air Intake Filter and chemically clean my intake using fuel injector cleaner additives directly into my intake, like if I was using seafoam. Most Fuel injector cleaners have high concentrations of PolyEtherAmines of PEAs for short, which is a carbon detergent, the exact same active ingredient on products like CRC GDI Intake Valve Cleaner, but all fuel injector cleaners have one or other detergent for this matter. Below, you will find a video explaining how to apply this method to your engine and another video explaining how I came to the conclusion that any Fuel Injector cleaner will do the trick:
