How To Clean Carbon Off Your Engine!
Вставка
- Опубліковано 4 бер 2023
- Today we test 3 different methods to clean the carbon out of your engine! We media blast with baking soda one cylinder to see the results, we then use picks (what most people would use) to scrape off as much carbon as possible, then finally, we try an internet method of spinning zip tips on a drill. Which one will work the best?

We Can really see, what harm an Egr valve does 2 the engine , which has to eat alll this shit , and gets clogged up just tooo much. So, the cleaning of the engine takes time and energy, which means, that the Egr valve really does Not eliminate the pollution of the environment, it just delays it on later , so it is Worthless , and just a terrible Deception to the entire Humanity, just as the catalysators Are, Because the building of the catalytic converters Also take Tooo much of the environment destroyed. And, That environment damage 4 the production of the catalytic converters wasn't "calculated", so, they have miscalculation , which again makes a catalytic converteers just another deception tooo. Thank you 4 the video.
can you stop whispering in the mic? Just get to the point. you are not funny.
Doesn't break cleaner ruin rubber grommets/ guide seals?
Talk less
Adding a zip tie around the bundle at the chuck end and another at the other about 2" from the end works well for focused agitation. Learned this growing up cleaning lathes and mills in family machinery business. Hope this helps. Great video.
Thanks for the tip!!!!!
Paul is the only person that could say the dumbest/funniest things and somehow have my full attention when explaining something serious 😂😂
It's the glasses
@@Traeh93 Maybe I should wear 2 glasses......I'll be unstoppable!
@@Deutscheautoparts this guy!💀😭😂
@@Deutscheautoparts one but double glazed 😆
Yeah he says some dumb stuff alright- like the fuel quality matters regarding carbon and sludge fouling of intake valves that are never in contact with fuel.
It would be really cool to see before and after dyno numbers on really gunked up valves.
if you actually NEED to see a dyno run to justify cleaning your intake valves because of this poor design ? then you really should buy a different car as it can only suffer in your hands.
@@mathewhoffer4541He never said he needed anything. It would just make an interesting video. You came at him for a scenario that you made up in your head.
@@mathewhoffer4541😮 I've never seen someone get burnt so hard as you pal
I don't think its performance you should look for, the purpose is avoiding failure in the future, but of course fuel will flow better when there is no deposits.
@@allancncdirect injection is sprayed in the combustion chamber at a high psi....... fuel flow? You meant air flow?
Best DIY option is vinegar & baking soda. Least that’s what the lady from the farmers market selling essential oils told me.
🤣
Jesus 😂😂
😂😅
Do not forget mint for a fresh exhaust ! 🤔🤔🤔
No for real crazy lady aside she’s right on this one. Vinegar in particular is amazing for carbon build up. I’m currently trying everything under the sun to get my Alfa Romeo started and one thing I did a few weeks ago was soak the cylinders in strong vinegar. My objective was more about the sludge from it sitting rather than the carbon but after a day of soaking I came back to almost all of the carbon completely gone.
Blasted the valves with walnut shells on my wife’s 2.0L turbo Santa Fe, restored its power. Wife said her car was fun to drive again.
Did you do it yourself or get it done at a shop?
@@theposerhoser did it myself.
Can you share links of what you purchased? Im losing hope @@jerrykurl69
Try cutting the blocks off the end of the zip ties, leaving them as long as possible, then put them through a piece of tubing maybe a few inches long, then put them in the drill. That would let you get them deep into the ports while keeping the drill away from the port, but they would not fly around so much because the tubing would keep them together.
I did exactly what you said on my mk6 r.. works great
I used oven cleaner, water, carb cleaner, a pick, a compressor airgun and lots of patience to clean the valves on my TDI. The oven cleaner worked FAR better than I had imagined, as a note of caution make sure you rotate the engine so that your valves are closed when spraying any liquid into that area otherwise you'll have a bad day when trying to start the engine.
Oven cleaner is a good at cleaning up stuff,, used it on some nasty crudely eng blocks
Don't use oven cleaner on an aluminium head. It'll eat the head away and produce hydrogen as a byproduct, which is flammable.
Yes, and after the cleaning , make sure that you do the Egr valve-off , so, that you never again have alll that dirty shit in your engine !!! ! !!!
Careful with oven cleaner, Mine is incompatible with aluminium.
Is TDI susceptible to this? I would have thought diesel was worse, but he didnt mention TDI as being a problem. What was your mileage and how bad was the buildup?
"It's an ingenious solution to a problem that shouldn't exist in the first place." - James May
That media blast is freaking dope!!!! Also for the zip tie method actually happy with those results!
Excellent explanation and I also enjoyed the comparison between the different cleaning methods. Well done! This youtube video is actually very helpful and covers just about all the bases.
Best video by far for understanding Mk6 GTI 2.0T carbon buildup and care. Thank you so much for putting quality and time into your video.
As mentioned in some of the other comments, before and after emission readings would be interesting to see, I don't doubt the air flow is ncreased and would help a better combustion; but the end result is always good to see.
On my 2018 VW Golf (Gen 3)TSI, change synthetic oil every 5K miles, use Top Tier gas, change filters regularly. This is the first time I have heard that these engines don't have big problems with carbon buildup. I had worried about this, but will continue to care for this engine. Thanks.
Double injection what makes them less problematic
Thanks, Paul! Your timing is flawless - I’m about to do this cleaning this week on my Mk7 and you addressed a ton of things I was curious about
And Don't 4get 2 cut cut off the Egr polluter of the engine tooo.
@@bustjanzupan1074?? Before cleaning? What is that?
@@The1Real1Cheese Because the "Egr" valve immediatelly pollutes your engine back on the old way. That is why it is essential to cut it off, 2 Not do any further damage 2 your engine.
I’ve been putting it off for my MK6, perfect timing! You convinced me to go with media blasting, seems the best way to not f- it up.
For a motercycle the "Italian tune-up" does work. Slower then a total clean in a garage. But it's free and works pretty well. FortNine did a video about it. And a lot of motercycle riders do it to get older bikes to gain a few horses back.
Thanks Paul. I have a 2016 Mk7 GTI with 200,000 miles. The car is still running great and giving 35 mph highway. I change the oil according the service reminder, approximately evey 10,000 miles. I bought it new and only used premium fuel, oil and filter.
I'm afraid it has the same carbon build up on the back of the valves. I've had the dealer do a carbon clean 3 time with crushed walnut shells. I'm starting to see the cold start misfire again so this will be the 4th cleaning. The first time it happened I got intermittent misfires. Everything checked out. It was the carbon. Thanks again to you and the humble mechanic. You-all helpled me to figure it out.
I think your paranoid. My 05 gti has 150k mileage and never been cleaned
@@andyscott0 the dealer showed me the valves before and after each cleaning. It was bad. The cold start misfire went away each time it was cleaned. I can post the pictures if you would like to see them. I am definitely not paranoid.
@France definitely sound paranoid. I have cars with 300k miles that still don't need a cleanup lmao. I own and maintain 5 of them myself and even when they look bad they typically don't cause misfires. If it got carbon buildup bad enough at that mileage then I'd assume you're doing something wrong or the engine has a unique issue.
If your vehicle doesn't call for premium, don't use it, thats causing your carbon buildup. All that changes is the fuels octane rating. When the octane rating is higher, it means it resists detonation which is good for sports cars, but for regular cars they can have increased trouble detonating it. I put premium in my Corolla while it misfired, because it was running too lean and caused a slight misfire, the premium made it less prone to misfires. Once I fixed the issue, using premium actually caused a rough idle. Use what is called for.
If you want to treat your car to nice gas, use chevron, costco, or texaco. They all use a high amount of detergents in gasoline that will actually clean the engine. Using premium fuel doesn't mean your engine runs any better or cleaner unless it was designed for it
@@alextheonewarrior thanks for the feedback on the fuel. The user manual for my mk7 recommends premium. I only use top tier fuel formulated with detergent. My use case is not the same as yours. I drive 100 per day on the highway for work. Maybe your cars have not seen as many highway miles. The engine does not have any modifications and it still delivers 36 mpg which is an indication of efficient combustion. The reason it misfires is due to the lack of a homogeneous air fuel mixture. The presence of the carbon around the intake ports wreaks havoc with the air flow pattern.
I think the zip tie thing would work better if you used the clip ends instead of the finger ends. The heavier ends and sharper edges would knock the carbon off quicker. Could then turn them around and do a "polish" with the finger end.
bottle brush.
@Ralph Washburn 🤣🤣
Weld or melt one end of the cable ties , will all hold together better . Make up a few mixed combinations of cable tie hacks , use drill in forward and reverse, don't use zip ties with small "metal" parts that "can" fly off or remove first .
I love ❤️ this channel when looking for real news.. dyi information is always helpful
I had to replace my intake manifold because of the flaps being broken and also cleaned the valves because of cold start misfires. The liquimoly valve clean is what I used along with some nylon brushes attached to my drill. It worked really well, just took a while.
And Don't 4get 2 shut your Egr valve off, so, that it does not repeat again.
@@bustjanzupan1074You run into other issues by blocking off the EGR. Your running at a hotter temperature, because your combustion is hotter, this leads to premature failure of seals, puts added strain on your turbo, and can lead to heat soak issues.
Paul, your timing is impeccable. I plan on doing this to my B8.5 this weekend. Phenomenal video as always!
I probably should do this on my '14 Cayman S with the 3.4 liter engine, but it runs perfect. I have a borescope at home, but getting it down that long winding intake looks like a huge hassle, not to mention you have to remove the rear interior just to get at the engine in the first place.
Great video!
Seafoam makes a great product if you can get to your throttle body it spray into the throttle body while running. What i do is make a tiny hole in the cai hose right by the throttle body push the hose through while car is running spray you have to work the idle to keep it from stalling
Thanks man,
I have a question though, does it clear the part where the valve touches it's hole?
Good to know that I have to wait a couple of miles to do the clean up on models 2015+. I remember seeing some videos that technicians use dry ice blasting to clean as well.
Thank you for this video Paul. I've been wanting to crack open my Q5's intake to service some parts and clean the valves. I wonder how well dry ice blasting would work. Keep up the great work.
Never thought about that sounds like a good idea, I would make sure valves closed do one at a time, Vacum up mess
And do not 4get 2 get your Egr valve on off, 2 not get such dirt back into a clean engine ever again !!! ! !!!
Great video!
In Europe, models from 2013-2017 have dual port from factory, avoiding this problem and better fueling for stage 3 tuning...
Was about to comment this! MPI is an option for pre facelift cars that is not that expensive.
@@XxSmokeeyxX so it can be retrofitted to DI (non-EU) cars? Cool!
@@petermolnar8667 of course. It's very popular on prefacelift cars. Unfortunately VW removed it and started using GPF instead for emissions.
I’ve actually looked into this myself. All the information I’ve found says that tuning is required to support MPI. So $800 ish for the kit plus a custom tune. Unless you’re planning to upgrade the turbo and go stage 3, seems it would make more sense to just pay for the cleaning. It’s likely only once in the lifetime of the car anyway. I’m just over 110,000 miles on my mk7 GTI and haven’t experienced any misfires, or drop in fuel economy that’s unrelated to a heavy right foot.
Keep up the goodwork you guys does!
I haven't done any valve cleaning on my Mk7.5 GTI yet(Only 34k miles on my 2018 bought new) but I owned a Focus ST before this car. I put 30k+ miles a year on that car as I traveled about 100 miles a day for work back then. Every year I would take the manifold off, soak the port in 2+2 carb cleaner for about an hour and use various size gun brushes in my drill. Got about 90% of the stuff off every time. The different size and shape gun brushes worked great and I barely had to do any scraping.
I've gotten good results soaking the valves in Berryman's Chemtool and using a series of picks and nylon and brass brushes. Not quite as good as walnut blasting but cleaner than what you achieved with just picks and brake cleaner.
We use the walnut media blast. After we get the cylinder to TDC, it helps to use a pick tool and a seal removal tool (I've never used this tool to remove seals. It looks like a tiny hockey stick) as the first step to get the majority of the carbon off. Then blast it with the walnut media. It is a night and day difference.
It does work nice(pick) for plucking out the o-rings on a Mk4 rack for the small hard lines, I found out last night as I rarely use them for seals also 😂
As always great video. Btw what's different in gen 3 engines that it doesn't have this problem ?
When I had my 2011 MK6 GTI, B12 and other strong cleaners weren’t available where I lived (Alberta, Canada). Canadian Tire just has your usual carb cleaners. Found that fresh oil soaked overnight (maybe only a few hours actually required) helped soften up the carbon, suspend it and also made it easier to clean everything. Used paper towel at first to soak up and remove everything and then compressed air to finish it off. Works very well and if any happens to get passed the valve stems or go down into the engine, I’m not worrying about it mixing with the existing engine oil and causing issues (as opposed to some strong cleaner seeping in).
The cleaning process is very good but I would use a nylon drill cleaning brush, I spray the valves with penetrating spray before using the liqui moly cleaner.
So those valves are impeccable.
Did the hand scrape and zip tie method last year on my b8.5 s5, worked pretty well. Definitely worth doing if you have the charger off for whatever reason.
How long did it take you I’m looking to do my s5 b8 v8
@@aqib2000 the procedure only takes about 30min to an hour. Getting the top end apart is a good half day adventure. If your not a regular wrencher plan on a weekend job.
@aqibi2000 The bulk of the cleaning gets done within 5-7min per port, maybe a little longer per depending on how much carbon and how clean you want it. I used a toothbrush with some cleaner to finish up. It can be done in a day if you hustle but more of a weekend project.
@@Mekanik.b Thanks for the info. Does a car need to be in neutral when rotating the crankshaft?
Thank you for sharing. What media blaster would you recommend to blast the intake valves?
Thank you for sharing guys!
Great video, I have performed the scrape and suck method and had great results. I also used gun brushes in fluid to finish and was able to get great results without having to use media blast. I recommend doing this every 30 to 50K.
What tool do you use to suck up the fluid?
@@i-khailvision7307I reckon you can just blast it out with compressed air
I recommend buying a car, that doesn't require this stupid procedure every 30 to 50 k, lol.
Just rev it
@@less_vanity5820 Nope, the revving up does not clean that shit. But the Egr-valve-off , Does the Best result 4 the Engine, which than stays Clean 4 Many Decades !!! ! !!!
I cleaned my 3.2 Audi using seafoam or Berryman and brass wire brushes- the pipe cleaner type I’d bend in a hook to get the backside of the valves, and a thicker spinny type to fit in the drill. Worked perfect. Cost overall about $250 for gaskets, brushes, cleaners, and lollipop wrench for the crank, saves pulling the front end but you wouldn’t have that issue with 2.0s. Took about 6 hours to get spotless.
WTF , if a little peice of brass gets in your oil pump or elsewhere GAME - OVER for engine you need mental health ?
I have done the same thing. Brass is softer metal than steel. I understand your logic, however, like Paul said: as long as you don’t do it like a crazy ape. I soaked all the liquid out with a rag and then walnut blasted with that special attachment that allows to stick the end of a vacuum hose. Works great!
@@ericsanchez3959 the head isn't steel
I've done the same thing, powerfoam worked amazing. I let it sit for an hour first. I believe I used either brass or plastic brushes. I then installed a AOS and didn't get much if any more build up after 30k miles. This was on a Subaru and the valves were much more recessed.
Been using the drill and zip ties for YEARS!! Then I vacuum the bits or carbon out followed up with carb cleaner and stuffing a paper towel in to soak up the carb cleaner and carbon residue before it dries out. It never looks perfect, but it's GOOD!!
Great video. I appreciate how explanatory you are. Keep it up 😀
Also you can do a zip ties AROUND the zip ties in 3 places to allow the final end to flare out, while the rest stay as a single unit.
I've used a soft toothbrush, a vacuum, and e85 with great results. Its more about soak time. If you leave the e85 in the intake port overnight it does great.
Great tip!
@@Deutscheautoparts Even though I know shops can't park cars overnight like that to do soaks 24/7 you guys should make a video. It gets the intake ports so clean they are silvery aluminum again.
@@kanadianmaplesyrup 85% ethanol and 15% gasoline from the pump. It melts fuel varnish away in old gas tanks in seconds is how we got the idea. Its a fantastic cleaner.
Hey you are awesome explaining things. I have a 2015 passat b8 1.4 tsi engine . Do you know if it has direct injection or ? I cant find exactly. Do i risk curbon build up too? Thanks in advance 😊
Great video! Stark difference between old and new. My mom wants to get a Q5, which year should I suggest she get? Anything over 2016?
I have an idea for the zip tie hack: instead of zip ties, get a long drinking straw cleaner brush. They’re like pipe cleaners but made a bit stronger than kid’s crafts items. Wonder how well that would work.
Yeah I’m honestly confused they didn’t even talk about using a brush. Seems like the obvious answer to me!
Harbor freight sells a brush set that includes a bunch of cone shaped brushes in plastic and metal, and can be attached to a drill. Those work like a charm. It's what I use along with media blast, and chemicals to get that factory fresh finish.
I just want to say, the overall video was real informative, and a lot of good advice was suggested here, however, I want to add a personal anecdote that conflicts with a statement made
The Gen 3 2.0T engines do have carbon buildup issues, though not as major as the Gen 2s and the older 2.0T FSI Motors. My 8V S3 started having Cold Start Misfires around 70k Miles that got progressively worse, and when I finally cleaned the valves around 80k, there was a tremendous improvement.
The Audi dealer local to me still recommends a Carbon Cleaning on the newer 2.0Ts at around 100k, so while the service interval has moved, their is still some Carbon Buildup that the revised PCV on the Gen 3 and newer motors that it can't resolve
Yep, I hear a lot about carbon buildup on mqb's with the 2.0t. My gti is around 142k and needs one bad, just haven't had the time to get to it
Thank you - I was doubting myself after his comment in the video - Ours has 75k, just started getting cold start issues (with the cooler weather). Replacing coils and plugs didn't fix the problem. I think I'm going to have to dig in before the snow flies
Mine shot a injector 4 malfunction code at 118k my intake is caked 2017 gti
Just shut that dumb Egr-valve off, and you will Not have this dirty exhaust shit in your engine anymore as before .
Thanks for the oil change kit and the brake caliper bolts, do you guys sell a slim 17mm box end wrench for the caliper pins or have any recommendations on where to get one?
Love your info and that you are not biased just to make money! Thank you
You should be using Carburettor Cleaner as it is 1000 times better than brake cleaner at dissolving carbon. Brake cleaner is a degreaser.
For me, the best video on that carbon build up .
200000000 thumbs up.
love your way to explain......
Hi Paul, great video. Here in Mexico we had a golf 1.4 tsi 4 cyl. I think its the Golf VII. Do u think that motor could have this problem?
Paul, what should one expect for the 3.6L VR6 in the Atlas when it comes to carbon buildup that’s well maintained with Liqui-Moly oil, top tier gas (91/93 octane), and Liqui-Moly Jectron?
I know it's probably not the project you talked about that's a secret, but it would kind of be dope if y'all made a *_Mazda 3 TCR_* since it uses the *_Volkswagen Mk7 GTI EA888 engine._*
Considering mazda decided not to actually do it and y'all are Volkswagen/Audi people, I figured it would be a nice experiment for y'all. I don't know, I just figured it would be a dope thing to put on your channel
Have done carbon cleanings on lots of gen3 2.0Ts and they definitely do have the same issue. Many of them I've seen at relatively low mileage with lots of buildup
Cheap gas and infrequent oil changes?
@@SouthsideTaxi Nope, just the Egr-valve shitty idiotism which is polluting every engine.
Hello mate firstly I love this video it's very informative. I've a question. Is it possible that if coke dropped in the engine it would damage it and would it be better to take the head off? Thanks in advance
Chevy V6 LGX with GDI - appreciated this video, even if it's not for my car's engine... thank you!
The spoon shaped o-ring tools are good for scraping the wider areas. I found the hook pick to be great for the back of the valve stems and a 90 and an angled pick good for getting around the valve seat. Removing the bulk with picks followed by media blast is the most efficient and quickest way. Bore brushes may seem like a good way to go, but they gum up almost instantly.
Cut the zip ties longer and place a 3/4 -- 1.5 inch long piece of 3/8 -- 1/2 inch diameter clear tubing (depending on your car) over the zip ties and use the tubing to control the zip ties while they spin in the drill
I DIY'ed the water pump at 150k km thanks to your tutorial and now I just did the carbon clean off at 190k km (120k miles). I had some intermittent check engine light and VCDS made me think it was a dead injector but when I opened it up it was quite like in this golf. Anyway thanks a lot for this!
Excellent job on cleaning those valves!🤩🤩
The zip tie bit was an actual TSB from Volkswagen/ Audi back in the day..🤔
Any reason why the gen 3 Ea888 motors don’t see as many carbon build up issues? To my understanding the euro gen 4 motors went to dual port but every gen 3 motor sold here is still only DI. Any Vw dual port engines here in the U.S?
As an EA888 owner, I’m curious how they prevent this build-up too!
yeah i was curious, ive got a 2019 GTI and I thought all of these engines had these issues, but apparently gen 3 EA888 dont have that problem?
They do have buildup, Charles checked his I recall and it wasn't great
2017 GTI owner here, Paul's claim that EA888 gen3 don't have this issue is bunk. At 50k miles my car had the intake valves looking just like the 1.8 in the video at 80k. I've had the car since new, 7-8000 miles oil changes with the right oil (LM or Motul), only 93 gas, all the maintenance done on time; on the downside it does have stg2 tune (w/ supporting mods) and gets about a dozen track days per year, so maybe a stock car that only gets driven around town will have much less carbon, but again "gen3 EA888 don't have this problem" is BS.
I did my own media blasting cleaning and it came out perfect. I got the Harbor Freight media blaster, the nozzle from FCP Euro and bought wallnut shells media from Amazon. Also replaced the water pump that started to leak, very easy to do with the intake off.
Probably improved pcv system
Had to get this done on my previous car (2012 Rio5) as it was DI and my fuel economy was dropping and was having some minor stall/hesitation issues with the a CEL once in a while. A local shop did it for me. I'm not sure exactly, what they did, but they did use a special cleaner on it. No idea if they removed the intake or not, but it worked good enough that I never had issue again. When I replaced that car with a new one, I went with a Toyota with the D4S system. All the benefits of DI without any of the negatives as it has both port and direct injection.
You nailed it with this video! Awesome!
Volkswagen is charging $1300 for that service
Cap. Mine was done at vw for $900
Still fair. Taking my engine apart and cleaning the engine is an ass kicker. I’m wishing I had just paid to do it.
Great Video!!!! Question, Why don’t the later MK7 GTI 2.0L TSI have the same carbon build up problem like the earlier years?
CRC intake valve and turbo cleaner works excellent on my 1.6 DIG turbo Nissan. The PEA (polyether Amine) does work very well without having to soak or scrape the valves. And I did confirm it’s effectiveness by viewing the valves before/after.
I use the same and you are right. it works pretty good.
Did you spray it in the intake or directly on the valves?
@@Jimster481 I just followed the directions on the back. Warm up the engine, then I removed the MAP which is just before the throttle body and sprayed it directly into there in small sprays while maintaining RPM 2000-2500. I usually do this every other oil change
@@Jimster481Directly on inlet throttle valve.
@@SuperChewy808 well I also did this with my QX80 and I can tell you when I opened the engine at 145k there was tons of carbon.
too bad we in the US don't get dual injection
Thanks for the most useful info
As I know oil liqui moly is very good oil
Will you recommend CeraTec liqui moly oil additives for Mercedes’ Vito 122 cdi engine?
Thanks in advance
Any recommendation for "STP Pro Series Intake Valve Cleaner"? Saw a video that Nates Interactive Auto posted with a before and after using the product, and it looked pretty good. Though I did see comments saying that carbon pieces could cause issues with the pistons. I'm pretty new to this kind of maintenance, so not sure if it's worth using it.
Would have thought string trimmer line would be a bit easier to manage in a drill than cable ties. Multiple diameters, cores, twists, and so forth are available. Mix and match and cut varying lengths.
The square 0.155" trimmer line works great. Soak the valves with BG carb cleaner & let set for an hour.
There are also rotary long stem wire brush balls that work well with a drill motor.
You can also go to the hardware store & buy copper pipe cleaners, cut off the handles & use your drill motor.
@@BobSmith-mc7uq I wouldn't use anything steel in a brush, which the pipe cleaners are
Toyota dual injection is the obvious engineering solution, Pure DI is always going to give problems.
Hi. Do you know if this can be done in my Vw Touareg 2006 3.2 V6 gasoline? Thanks
I have another "tool" try out for your consideration. Furnace or boiler brushes are used to clean out carbon soot from the internals of boilers and hot air furnaces. Sets of these tools are available from any plumbing or HVAC supplier and presumably Amazon. They come in a variety of shapes and sizes. Brush work plus brake clean solvent might be an effective way to address this problem.
How about an engine that doesn't eat its own poop? The root of this problem is not direct injection, but the incredibly stupid emissions exhaust gas recirculation system. Without EGR the intake valves would never be exposed to exhaust soot.
Is there an aftermarket EGR bypass somewhere?
@@jordanburrack6404 blocker plates exist, but they are highly regulated as emissions bypass equipment
DI is such a bad design. You'll never convince me otherwise.
How is it a bad design?
The best is dual injection for sure
Agreed, but MPI adds double the injectors and more complexity. You'd imagine 1 larger injector upstream in the manifold and after the throttle body could help mitigate
@@djsg143 Indeed!
I'm a fan of the Stratified XtraFuel system for this reason, and am considering adding it to my GTI
Wat the hell u talking
I have a 2018 kia soul plus with the 2.0L gdi engine it have about 105278 miles do these engines have built up on it
Thank You Paul for this. That racing line catch can I bought from you, best investment I have ever made.
We appreciate the purchase very much!
Nice! You guys sit in Cornelius. What is the charge for that service?
Would port and polishing help reduce or greatly eliminate the build-up as well as help with performance?
Awesome video, extremely informative 💪👍👌
I wonder if you sprayed them with that stuff that gets really ice cold wether it would just crack off loads easier with picks etc ? I’ve seen this technique used on sound deadening removal
These videos are always super interesting 👌
Paul One Question, Watermeth Do You Think Help To Carbon Build?
Great video Paul. Thanks very much
I have 2015 Audi a4 premium plus around 50000 miles should I worry about carbon buildup?Thank you.
This was a really great and complete video. Thank you Subscribing.
Zip tie method... very cool... thanks for sharing.
ZIP TIE method: love it!
The Zip Ties work wonderfully
Awesome information but what do you do for the intake manifold part? I got an S3 8V from 2015 at exactly 120k miles and it's in a bit worse shape than the one featured in the video. I have intermittent engine light caused by misfire in zyl 2. I just removed the intake manifold in order to pull out the injectors and clean them with the ultrasound but the problem really seems to be the sizeable carbon build up.
I'll try the ziptie hack for the valve part but the flaps in the intake manifold are quite crusty too and I really don't dare puting metal picks on this plastic thing. I'd appreciate some advice ^^
You know what? I'm looking for some parts for the GTI at the moment, and appreciate this video that UA-cam threw at me. Gonna head over to your website now.
Hopefully you mention the illustrious 2.8l.
Do you have any specific shops you recommend in the Raleigh, NC area?
I purchased a 2018 TT and was planning on establishing a long term mechanic in the area (I’ve been less than impressed with the local Audi dealership).
hi what do you think of Red Line Synthetic Oil. SI-1 Complete Fuel System Cleaner is it any good does it help at least a little or not at all ? For direct injection carbon build up.
Good video as this is an issue with most high mileage vehicles. I like the idea of using the baking soda over ground walnut pieces. Baking soda can even be used to strip paint surprisingly.
This issue of the pollution of the engine comes just from the Egr valve, and is Not caused because of the hight mileage. I have seen engines Clean after 300 miles, but with the Egr-off . So, after the clenaing of the engine, make sure, that this issue does Not repeat again, by shutting off the egr valve.
I have a new 24 hyundai 2.5 turbo, how or is it possible to keep the valves clean ? or a way to help prevent carbon build up? Thanks in advance Dave
Media blast good, Thank you.
Italian tune ups do work to a point. You have to have a fairly well maintained, clean engine though.
What makes the newer motors have less build up? Is it dual injection? Or what did they do?
How much does your shop charge for this service?
Is this just a turbo direct injection issue? Or do NA applications suffer from it too?
