    I bought a used VW FSI 2.0T that was seriously clogged. I removed the intake, removed a lot of the carbon using soft aluminum 'chisels' about the size of a flat screwdriver, being careful to ensure the valves were closed so nothing could drop in the cylinder. Then I used a small tube attached to a vacuum to suck out the loose stuff. Then I squirted Castrol Purple cleaning fluid into the head intakes and agitated it around using an old nylon toothbrush and sucked it out a again. I repeated this for each intake throat until they and the valve heads were completely clean. It took an afternoon to clean all eight intake valve throats so they looked like new. Castrol purple is awesome! I have installed a catch can system to the PCV manifold. The car runs great now. Total cost, including the catch can. plumbing and PCV manifold mods was less than $80 and well worth it.
    I have yet to meet anyone that has actually achieved anything except clouds of smoke out the exhaust using these various chemical concoctions before paying a mechanic to take the manifold off and physically remove the coke. Don't waste you money. Take the time and do it yourself.

      Pretty much what I did on my 1.9 diesel which are known to cake carbon though I used different product. I used oven cleaner, carb cleaner, water, a pick set, wet dry shop vac, and an air compressor air gun. You just have to be careful, you have to rotate the engine and make sure the valve you're working on is closed then scrape the heavy caked carbon with the picks and vacuum it out. The spray the oven cleaner in and wait for a bit, then spray water in and finally blow out with the air gun, final cleaning is with the carb cleaner to remove any residue. Rinse and repeat on each one until its clean. It got the intake area impressively clean.

      The spray-in intake valve cleaners are intended for maintenance purposes, every 5k or 10k depending on your vehicle or how you drive. It's not for cleaning out years of caked on carbon build-up on the intake valves as your used car purchase.

    Humble Mechanic did a video on this like a year or 2 ago.
    Easiest thing to do is...
    1. get a bunch of small zip ties
    2. tape them to a small dowel that you and put in a cordless drill
    3. remove intake manifold
    4. with valves closed, flood the port with brake clean and let it sit for like 5 min
    5. With your mcgyver'd brush in a drill, and run it in the port.
    6. soak up/remove the dirty brake clean with a rag
    7. repeat with the other ports (with turning the crank by hand to make sure the ports being cleaned are closed)

      My 1st 4 cars were Alfa Romeos. If you didn't thrash them @ least once a week they would start running like crap, probably because of their appetite for the oil. So maybe an 'Italian tune up' was only a neccessary for Italian cars?
      But maybe not. Decades ago my boss had a Mercedes. He asked me to take it to the dealer because it had no power. On the way I gave it a thorough thrashing. At first it was definitely sick, but as I neared the dealership it was going much better, so I turned around and thrashed it all the way back. When I got back I gave him the keys and told him it was fixed.
      After his puzzled look I told him that he should not not always drive like grandpa.

    I have a very simple vacuum operated water injector I built with some basic fittings that I use on a GDI Kia. While I haven’t visually inspected the intake valves, it has been running progressively better the longer the devise is in use. I also think that in addition to cleaning intake valves, it is important to clean the injector nozzles as well, I believe that they get carbon deposits on them in the combustion chamber and these deposits disturb the shape of the spray pattern. This water injection system is in my opinion the very best way to decarbon everything in the combustion chamber, perhaps most importantly the injector nozzles. I’m not a fan of GDi engines, I understand the benefits, but I think they come at too high of a price to be worth it in the long run. Give me the old port injection any day.

      Yea well I wonder if a water injection system would help.
      I ran a homemade one on my tdi for years, and also routed the pcv somewhere else.
      When I tore it down after 60k or so, the ports had nada buildup and the pistons and combustion chambers didn't look like a diesel.
      It had black on it but not any thick carbon at all.
      You'd get a dirty finger if you ran it down a port wall but it was clean as a whistle.
      My setup blew right in the turbo as I had no intercooler on that setup, so that's easy.
      With an intercooler it could puddle up and cause issues , at that point it's better to pressurize it and inject after the intercooler.

      @RickinICT 4 ปีที่แล้ว +14

      @@GlennC789 When I did this on a GM 3.0 V6 (100k miles, had never been cleaned - it was bad), I pulled the intake and turned the engine over by hand til the valves I wanted to work on were closed, then used a set of long picks to break the bulk of the softer crud off. If you use steel picks, be careful not to score up the valves. Then I used a shop vac to suck as much of that crud out as I could. Then, I sprayed some CRC GDI Intake Valve and Turbo Cleaner directly onto the valve stems until the little pocket they sit in in the head was full, and they were submerged in the stuff, and let it soak for a bit. Then I uses several sizes of long handled copper and nylon "bottle brushes" that I bought at Harbor Freight to scrub off the rest of the crap, then blotted it all up with shop towels. Don't suck it out with a vacuum, I imagine it would explode! After I'd gotten the stems and back of the valves pretty well cleaned up, I turned the engine to open the valves and scrubbed the mating surfaces between the seat and valve the best I could with a thin but stiff nylon brush. Then I moved on to the next cylinder. All in all, I think it took me a solid 6-7 hours (like I said, they were in bad shape).
      Now, the CRC cleaner is meant to be sprayed into the intake with the engine running, like the product shown in this video. I did use it that way after the manual cleaning, but it would never have gotten through the buildup without some manual action on the valves, as bad as they were. But I do believe the stuff is legitimate for routine maintenance, and would probably prevent the buildup from ever getting that bad to begin with.

    There is one true fix, Ford calls it dual-fuel, Toyota calls it D-4S, even VW has already implemented their solution in other markets. Multiport fuel injection, add some good old port injection to a direct injected engine to keep those intake valves clean. This is the reason I traded my 2015 F150 for a 2018. Thankfully the aftermarket has come to the rescue with kits available. I'll take a good look at the options once my water pump goes and I have to pull the intake manifold.

    Hello, EA211 TSI owner here. If feels like you dumped the stuff into the cold engine, considering how the engine rattles. High temperatures speedup such chemical reactions - try cleaning carbon buildup on a hot electric kitchen stove vs cold, you'll see how easier hot one is dissolving. :) So the overall result would probably be better when the engine was fully warmed up.

    Quite a few years back when i was still a stupid teenager i used to drive my car like if the road was a race track. Litteraly going as fast as the car and road would allow me to, and redlining the crap out of my engine in every gear. I drove a 1999 ford escort turbo DI 1.8 Diesel completely original except for increased boost and according adjustments to the fuel injection pump. All the factory egr and pcv system hadn't been tampered with.
    I once dismanteled the intake and egr valve and to my surprise they were absolutely spotless, no sign of carbon build up what so ever. I was quite impressed to say the least ! So i actually do believe in the italian tune up.
    Also, when ever a client comes to the garage with huge carbon/oil build up, the car is usually owned by someone who isn't driving it hard enough. The best advice (in my opinion) i can give them is to beat the hell out of their engine once in a while to keep it clean.

Take into account today's fuel has been diluted not just with ethanol but a bunch of additives (try evaporating gasoline and see what percentage of additives are left. Add to that all of the emission controls vehicles have and you can see how much more efficient engines are today.

Your technique may work also 🍻 I hate these direct fuel injected cars. Port injection or electric the way to go. Just add more gears to be at a lower rpm at cruising speed, if they want to save fuel. Direct injection and auto start systems ends up burning more time and resources as it requires more frequent fuel pump replacement due to higher pressure, fuel injectors replacement as the seals goes bad on them when removing to clean the carbon, and starters replacement from repetitious ignition. That's not even factoring in the time or resources to get and stock those parts on the shelf. But the government likes the tax money, the dealer likes replacing and over charging for parts, and the people can care less because there's no pride in ownership (lease and replace cars in a year or so). So that small amount of fuel a direct injection system might save does more harm than good. Like said, just more gears lower rpm would equal the same proficiency.

    The driver's side, the clean side, vents to just below the air cleaner above the throttle body.
    I always assumed the PCV side of the engine would allow blowby vapors into the engine.
    I installed a catch can on the driver's side and I was surprised to see that moisture and snotty looking stuff inside the can. I now have suspicions of a head gasket leak at the same location, allowing water into the lifter valley just as before.
    I'm thinking positive about this. If moisture (steam) kept the rocker arms clean, maybe this moisture being sucked into the engine is keeping my intake valves clean. 😁

    The old old PCV system that dumps PCV vapors on the street was the 50s and before, PCV systems as we understand them now started in the 60s and would recirculate vapor through the intake as well. Some would put it back into the air filter housing, some would put it into the carb spacer to be drawn into the manifold. In terms of function, not much has changed since then, except perhaps the efficiency.
    It is common on old performance builds to simply use a breather cap on the valve cover to vent the vapors through a filter and let them go to the atmosphere. Not the best way but certainly simpler than the modern vacuum routing, or especially the 70s and 80s vacuum routing.

Our second car has over 100,000 miles on it and when my mechanic cracked it open to do something else he said it was the cleanest engine he'd ever seen with that many miles.

    I fully agree, intake spray cleaning is a Preventative Maintenance procedure. It is strongly recommended you do it every 30K miles on GDI Engines BEFORE you develope the build up. Once build up occurs, chemical cleaners have little effect and expensive physical cleaning will be required.

    Good presentation. I noticed that most of the GDI carbon buildup presentations mention the need to service catch cans as an issue.

    I still think the best solution is choosing an engine with dual fuel injector, one for the cylinder , the other for the manifold. However, you are stock with a direct fuel injection system, perhaps the easiest way is switching to synthetic oil which has a lower vapor pressure and so less crankcase vapor to start the problem.

    From what Ive found after doing at least 50 of these carbon cleanings on the 1.8 and 2.0 FSI motors, premium gasoline works the best for eating away the carbon. Ive tried a ton of different cleaners, from Wurth, Techron, Napa, Berryman etc, and they all needed much more time to soak through and eat up the carbon. Premium gas can cut it down in under 30 minutes.

    It's not only the PCV system, but the EGR system as well. Another contributing factor is the use of low tension piston rings which increase blow-by. Lastly, forced induction will make it worse. In all honesty, DI engines need decarining every 10k miles because by the time you notice it, its to late. Nothing you put in your gas tank, nor what kind of gas you use will have any impact on this kind of carbon buildup.

      Catalytic converters are covered under federal warranty for 8yrs or 80000 miles and most chemical companies will give you an additional warranty for using their products as long as your in a certain mileage range.

    Chrysler was selling Port injected cars in 1956. The only issue that they ran into, was that the condenser raps were not insulated against radio interference from bad Transformers out on the road. And if you got near one of them it would start acting up. Surprisingly they were not able to figure that out before they had sold their injection systems to bosch for them to work with.
    Surprisingly, that original 1956 system when you correct and rewrap those exact same condensers resistors, they work wonderfully.
