How Much Carbon Build Up at 10,000 Miles?? ~ 2019 Golf R
Vložit
- čas přidán 26. 07. 2024
- The Golf R has 10,000 miles now. I was very curious to see how much carbon build up was on the fuel injectors and on the intake valves. Carbon build up is VERY common on Direct Injection Engines GDI/TSI. In this video we will remove the intake manifold, clean and inspect fuel injectors, clean and inspect intake valves and ports. I will also show you 2 ways to clean the intake valves if you do not have a media blaster setup. Cleaning intake valves can be done, you just need to be careful.

This level of carbon buildup on a car with so few miles and so well maintained, whilst not a 1st world problem, is still worriesome for an owner. If you want your engine running it’s absolute best this a constant time effort and cost that most ‘normal’ owners would never factor into its ownership.
This is very eye opening! I love watching your videos because i get so intimidated to attempt this type of work on my own vehicle's. Your skills and knowledge are priceless.
I'm glad and saddened you took the time to do this. I was hoping for less buildup at 10k but I am a firm believer in low VOC synthetic and periodic highway drives of 3-4 hours to minimize in these powerplants. Great work sire.
I am currently working on the Injector and Manifold DIY!!! Should have those up for you guys soon
I'm holding my breath for it......don't kill me!
@@tonijohnson09 LOL I am working on it now. It's a big in-depth video
@@HumbleMechanic thanks so much for all you do! I've been waiting for this video!
@@HumbleMechanic 😳🤤.......you will not understand how 'on-time' these videos are. Blessings 🙏
This engine is 2.0 TSI?
I found it very interesting to see "dirt" patterns on the fuel injectors, and I agree with you that it is likely related to the in-cylinder airflow. I used to observe something similar (in my case, dirt from unburnt fuel) on a transparent single-cylinder research engine I worked on. Carbon build up occurred every time we fired the engine, it was visible on the cylinder wall, head, etc and would change patterns slightly between port-injection and direct-injection systems.
The only way to stop this is to route the blow-by to a separate collection reservoir that is removable for maintenance of emptying and cleaning on a regular basis. Like oil changes with a warning system in case of overfill or clogging. That goo should never be introduced to the intake ports.
I am absolutely appalled at how carbon-fouled the intake runners, cylinder heads, injectors, and especially the valve stems are. I've seen old engines with 150K with less carbon deposits. Is this progress?
GDI is an inherently flawed design, regardless of the power/efficiency gains. When an expensive service like de-carboning is required maintenance, that offsets any efficiency gains, at least from a maintenance cost perspective.
VW and other makers need to put catch-cans and part-time upstream injectors to clean the system out! Ridiculous!
BTW - great video as always Charles - keep safe brother!
No, it's moronic engineers who thought they had a great idea. A liberal college education at its best...lol.
@@icanfartloud wellllllll i'd like to see you design an engine. or would you need a "liberal college education" for that? lol
This is mainly an European car manufacturer problem. Not an issue with Japanese and some domestic cars i.e 2019 Mustang GT 5.0 actually has 16 injectors using multi-port injection. Uses port injection for cruise and low load, direct for high rpm high loads
Mike TeeVee this is more a problem in the US, because of EPA standard, the intake manifold has four holes for four extra injectors THAt are supposed to spray fuel over the valves to clean them but unfortunately we don’t get that in the US
@@d1zguy864 The euro spec golfs get dual injection, for some reason we don't get that system in North America. Maybe because of emissions or something.
Charles. This is the far best video ever I've watched. This is rad! I enjoyed every bit of the job you did. I learned so much! Thanks for putting it out! I look forward to see more of DIY maintenence! Many Manny thumbs up!!
Thank you very much for the time and effort put into this well produced video. You've given lots of great nuggets for tackling this maintenance procedure.
Thanks Charles, for highlighting the carbon buildup problem with these GDI engines. GDI has always seemed to me like a superior fuel induction technology for gasoline engines in theory, but the practical aspects of its maintenance drawbacks seem to nullify its advantages to a large degree. The hybrid injection systems, like on the gen 3 Ford Coyote 5.0 engines, seem like a good solution. I do like the more precise fuel metering capabilities with GDI NA engines being able to run higher compression ratios.
I think it would be interesting to test the effectiveness of oil catch cans in reducing intake tract deposit buildup on engines with and without the cans over a prolonged period. It might give some insight into the contribution that cylinder blowby vapors are making in the formation of carbon deposits on the intake valve faces.
My 2018 S3 is approaching 30K miles.
This amount of carbon buildup is alarming.
Rob L. If you haven’t done any type of autox you won’t see heavy build up. Autox is a real issue with the oem pcv valve...
@@markd3891 You don't know what you're talking about do you?
Olle Jansson I own a 16 R dsg. Maybe the way I explained wasn’t too great. All DI engines will built up carbon eventually.
At 30k you are close to beginning stages of clod start misfires. I always push the induction service on my customers every 30k.
Lynx Star Automotive Yeah it’s interesting on the gen 3s versions. My bro’s 15 S3 always had a rough cold start idle like miss fires from new, my 16 R (24k miles atm) never had any of it like my bro’s. My friends 16 R is at 63k & it sounds literally the same like mine. (Plans to diy at 65k). From what I’ve seen & witnessed, the gen1/2 would carbon deposits like no other ~30k while the gen3 being more reliable seems to be having carbon issues anywhere from 60-80k. Luckily we don’t have timing chain issues but the dreaded water pump remains the same.
Solid video. Thanks for taking the time to do this. VW should be paying you for helping educate and remedy a problem they created. Direct injected engines suck. Negligible fuel economy improvements with many drawbacks. Land Rover Audi guy. I know my way around a wrench for the piles I love. Keep up the good work man!
Charles you’re awesome! Thank you for making such a detailed video. This is truly amazing!
>laughs in port injection 1.8t
*laughs in throttle body injection*
From what I understand, Toyota uses 2 injectors per cylinder (D4-S) for some engines. One direct injection and one port injection, just to avoid this exact issue.
Euro market ea888s have that also
Toyota is also the few manufactures that pretty much skipped the Direct injection phase and went straight to dual injection. I guess it wasn't reliable enough for their standards to justify the power gains.
0812rs VW uses dual injection on the new 3.0
@@sl0907 Lexus learned their lesson with the 250. My GS 350 has D4-s. I did a bore-scope and it looks new after 100K. I do use techron but probably not needed.
alb12345672 I do not work on Toyotas, but I read an article on their dual injection system, and it is much more intricate than just spraying to keep the valves clean. The system switches between both injection types depending on many factors. Load, a/f ratio readings, throttle position, temperature, etc. Seems at idle the system mostly uses the port side. Under heavy load, and cold start it uses the GDI. While cruising, the system varies.
Awesome video as always Charles! I gotta get mines cleaned up. Will probably do that after this coronavirus is done with. Keep doing these great vidz!
Good to see the Golf R back after a while
Learning a lot from you sir!
Thanks! got 3 more killer R videos coming soon
So v power and treatments are a waste of money. Save it for a carbon cleaning.
Well in this engine the fuel doesn't come in contact with the valves so, yes treatments won't have any effect in this engine because it is direct injected. If you had a port injected engine then those things may help.
@@Cimone90 what about pistons heads and injectors? They benefit from Vpower and cleaning treatments
@@maxdruciak2724 yup. You're right they do a bit.
@@Cimone90 Using CRC GDI Intake Valve cleaner through the manifold helps a great deal. I own a 2015 Golf R @ 52k and have never had a misfire. Have only done that treatment twice though. I drive my car hard as well.
No. They still clean as advertised but the injectors are "directly" in the cylinders, hence the name Direct Injection.
A catch can to minimize oil contaminants in the intake system and CRC intake manifold/valve cleaner will be your easiest solution to keeping the valves clean.
VW needs to have a dual-fuel injection for the USA. This is an unnecessary headache left for the customer to deal with.
Those are the best videos by far, thanks for your very detail explainings...👍🏼👍🏼👍🏼
That ziptie trick is something i never would have thought of. I will try that when i do my carbon cleaning.
Truly shocking engineering. Going back to the 70s when we had to pull the cylinder head off every 10-20 k miles to do a decoke. Not progress.
In europe volkswagen even puts rear torsion beam suspension on the entry levels golf while they didn’t on previous generations. They really cheap out on every generation if you look into it.
In terms of reliability they do really good here honestly in America they are probably not build as well or have a different tune because the only people complaining about Volkswagen seem to be Americans.
@@JMNTN ın europe all mqb platform cars under 150 hp sold with torsion beam rear end until mk 7.5 i dont know the new generation. I have a 2016 seat leon 1.6 tdi 110 hp 5 speed manuel with torsion rear. Seat is the cheaper brand of vag group and leon is more sportier design golf. Beside all other design and engineering flaws worst one is rear suspension. Comfort level is lower than all rival cars. Thats why i will never buy a vag group car again. Fuel milage is very good around 40 to 45 mpg diesel but there is a clicking bomb comes standart with new tdi engines. Emission equipment. You must be sure your egr system dpf etc gonna hurt your wallet.
I have TSI engine. Okey it's not 2.0 Golf R. It is 1.2 but still I have driven 110 000 kilometers and I have zero issues with the engine. I usually use regular 95 octane gas. I used maybe 3 full tanks of 100 octane in my life with this engine.
@@Romif_SK early 1.2 tsi engines are prone to timing chain failure resulting engine replacement. 1.2 get better later. Now i wonder what will happen to 1.0 tsi
Got memes? I believe it’s because 1) they aren’t as well made here, 2) parts cost more here, 3) people don’t know how to work on them here so it costs more, 4) we drive WAY more then you guys do so you wear out cars faster if they aren’t as well made. For example a car in the US should make it to 200+ thousand miles with minimal problems for it to be considered reliable. Whereas in Europe it seems like most people only go for 100 thousand ish.
Good video bro and always love the work you do!! Keep it going.
Also just did my injectors and a carbon clean on my 2015 gti at 43k miles. One injector was bad so I figured do the carbon clean while your there.
Overlay is the best!!!
Excellent tutorial again, btw. Great work man!
Great video Charles.... keep them coming
That's crazy that this cleaning even has to be done.
@Private Eyes No, VW sends their crap all over the world. That's because vw are crap in general.
@@Nick-GR VW is ok. Its that theyvlike to stick in the past and have to obey the EU like a good little dog. Port injection shouldn't have been phased out
The benefits of direct injection petrol are outweighed by the disadvantages in my opinion. After 10k miles that’s way worse than I’d have hoped if it was my car, and this issue could probably easily be avoided just by something as simple as having an extra rail of indirect injectors that are set up to inject during cold starts, or something along those lines. It’s not even like it’s a new design that’s got teething problems, this has been an issue on just about all GDI engines since they were introduced.
Forreal
Great video! That's an easier job than I would have thought. Thanks!
Outstanding job! Awesome video with great pics and great narration! This guy has a radio D.J. caliber voice, with a no nonsense straight to the point description of what each DIY'er is looking for!
I pass on to all my friends your links and praise. Keep up the outstanding job Humble Mechanic!
Damn... This guy was super careful with all those treatments and WOT pulls to keep his low mileage engine as clean as possible and still there was significant build up... I'll keep running my port injected engine. No direct injection for me for as long as possible, thanks.
I'm so glad I still have port injection.
Even though you have a VW and I have a Hundai the advice on the GDI cleaning and maintenance serves me well on keeping my vehicle trouble free!
Very informative video....I'm starting to get a lot more volkswagens in my shop and I find every one of ur videos top notch ...thank y humble nechanic... u r the vw guru
Europe gets a secondary fuel rail(with lots of other perks) which eliminates carbon buildup problems, idk why US still not worthy...
Doesn't the Subaru BRZ/Toyota 86 have both direct and port injection in the US?
You would think they would make it dual injection considering how they might payout if something big happens within the 6 year warranty period.
Aleksander Rysiewicz yup it has Toyota’s D4S so both port and direct
Yeah i have a 1.8tsi ea888 gen 3 in my car in the uk and it has dual injection, 2 per cylinder.
@@calm7677 They also make like 140-150 to the wheels.
I remember pulling the intake manifold off my MK6 GTI at 240,000km and the carbon was caked on! Cylinder 2 suffered the most because airflow from the PCV port is closest to that cylinder. Mind you the car has probably never had carbon cleaned off before.
Yep 2,3 are usually the worst. That is why I did 1/2 for cleaning. Also the valves were already closed. LOL
I've been holding off on doing MPI. I am definitely adding it this summer. I have 20k miles on my 2018 R and am not looking forward to what I will find. Amazing video BTW!!!! Keep up the great work!!!!!
I am kicking that around too.
Great info here. I'm almost at 40K so I think I'll tackle this job in the summer as preventative maintenance.
102,000 miles on my GTI without a clean. Wonder how lovely that looks. No misfire issues and still getting 33mpg 🤷♂️
Well, that's good. My R is at 8800 miles and this video was making me get worried. Still think I might clean it, maybe at 20k or something.
93K on my 2011 Gti and can't imagine how mine are. Used the CRC stuff through the air mass meter along with Techron for the injectors(pre-oil change) and I've managed to convince myself that I can feel the difference.
K C Shhh it'll hear you!!!
@@chris746568462 same here...
How long have you owned it? If you bought it used, I’m willing to wager it has been done by previous owners before you.
Ive used seafoam through the intake air temp sensor of my wifes car since the last carbon clean 30k miles ago. I use it every 3 months or so. But i dont want to pull the intake to see if it works
Electronic toothbrush works great , easy to change heads . Great video bro!
Great video, now I know what to expect approaching 10k.
I have a MK6 GTI and live close to you. Any interest in taking a look at that for a video?
You should do an induction style cleaning at the next 10k to see if it makes a difference.
Love these type of videos 👍🏽
You're amazing! I was looking to do this because of a cold start misfire and boom: problem diagnosis confirmed.
You’ve been working for Volkswagen for a long time, and that surprises you? Your love for those cars must be large
It only surprises me because the gen 3 EA888 isn’t like the one before. Had tons of low mile intakes off for the fuel line recall. This is probably among the worst.
I would be interested to see how this differs from the eurospec multiport injection engines, or with an aftermarket multiport kit such as the one offered by APR.
@Matthew Dunlap do you know how EFFECTIVE is the EU multiport injection system ? does it completely solve the carbon build up ? ( I'm asking you this because I'm aiming to but a 50K miles Passat B8 here in Argentina which comes imported from Germany plant and I already confirmed that it DOES have the direct+indirect injection manifold... but... is it 100% EFFECTIVE against carbon buildups ?
@@opablo_gm I can't say for sure how effective it is. Most fuel has additives for cleaning, and fuel itself can act as a solvent on the carbon. It may not be 100% effective, but it should be much better than direct injection.
@@MatthewGDunlap Yes its 100% efektive! Even on high milege cars intake is clean, i speak about 250k km cars! Its clean because of that system inject the fuel in intake valve, if carbon wich is not burn in cilinder goes in intake then fuel wich is injected in intake clean it and then no problem, its self cleaner(mpi). But speaking of Golf R even the European version of 2019 post WLTP emision regulation doesnt have mpi, it have just like american golfs direct incjection! So the problem is the same! Only pre WLTP cars version with 300hp prefacelift and facelift version with 310hp in Europe have mpi. Favelifted version with 300hp(post WLTP) doesnt have one! Its a shame on VW to do this in order to cost saving!
trader 247 Although high mileage is relative, higher mileage in the states means 250k miles. That’s only around 156k miles. It’s still a lot but it isn’t as much as we consider high mileage.
@@shadowthesi Yeah u r right! But because here is video of Golf R wich is performance car, 250k km is a high mileage! So if in that condition doesnt have a problem, thats it problem is solved with mpi!
Great video. Keep up the good work!!!
Thanks for posting--great video. Two things:
1) The R specs 0W30 504/507, which is significantly heavier than the 508 spec
2) I've strongly recommend never using a Scotchbright pad in any engine, ever. Even though the valves are closed, there are small (40 micron) aluminim oxide particles that are bound to make it past the valves, no matter how careful you are. Most engine remanufacturers warn against this, and GM had a specific TSB regarding the use of them in their engines. And, there's really no need to do it. Zip ties work fine.
I just performed one of the most interesting services to my vehicle (zip tie method) and the before and after was similar to most of the walnut blasting reveal photos I've seen. Spent a total of 20 bucks!
I think the fuel quality plays a big role in here.
we in germany have 1.2 ltr turbo toyotas with direct injection.
most of them run perfectly fine.
some are terribly bad. completly gunked up, it even cuts out. with 40.000 km's
these engines need some catch cans or like an old scool central fuel injector, just for cleaning.
but its a toyota. you remove the intake in 5 minutes.
I'm lucky I live in Europe. And these engines have Port injection also.
2019 onward don’t have MPI anymore in EU/UK.
Do you know if the 1.8 engine in Europe are mpi?
@@KasamS I believe so.
@@cfbm125 lucky mines 2016 😉
Alan Ton Same here, my GTI is a 2016 also🙂.
Thanks for another great video!
Great video man, you taught me alot that I didn't know thanks 👌
Dang do I feel good now about having MPI on my 1.8T now 😂
Is that the 20V engine?
I just love how VW doesn’t believe it’s a real issue. It’s just a shame.
They do now. They have a special tool. LOL It's been known for a long time in the service side. both at the dealer and higher up
HumbleMechanic Every VW/Audi should have this cleaning acknowledged as part of interval service manual. Plus be upfront that these vehicles will need this procedure done every ~20k to maintain its function and reliability at owners expense.....or they could just fix it in entirety by fitting direct and port injection for the future vehicles.
This and the ridiculous oil consumption due to poor seals just gets ignored by them. They don't care because by the time it goes bang the warranty will have expired.
@@BlatentlyFakeName Audi did a rering job on my 2.0 TFSI free of charge nearly 20K after waranty was up. I also did not qualify under the bad piston class action suit but they did it anyways. Audi does care.
It's not a real issue to them when there are no problems during the warranty period.
Very nice work! I'm not sure I have the expertise to get all the valves closed in both my vehicles, but at least I learned how to properly clean valves. I have a Tacoma and a 10th gen Civic.
I hate working on my mk6 gti because the engine bay is so tight, but watching your videos gives me the itch to tear it apart and fix my intake flapper valve
I believe something such as CRC would be perfect for an application like this. There's such a thin layer of carbon I believe it would be able to clean those values very well. Too many people use CRC at such high mileage that there's no hope but to use something such as walnut blasting. Also It's funny because just the other week I was looking for information on low mileage carbon build up and this video was just want I needed, thanks for the quality content!
RIGHT! If you do those intake treatments as PM you might prolong the issue. but if you have carbon build up symptoms, it will not fix it
@@HumbleMechanic exactly, once I get my GTI in the next couple months I plan on doing intake cleaning every 5-10,000 miles so hopefully I'll never need to take the intake manifold off
@@garrettbundy1810 not same brand, but I've used CRC spray on my GLA since 2015 to 2020, and did not have issues.
I have a GLC300 now and continue the same trend, every 6 months 1/2 can CRC let it soak, drive it.
I WOT a lot too and always use quality oil meeting the specs.
Again, different 4 cylinder brand and design, I know the Mercedes PVC system is far superior to others on the market. But I've never had an issue, and intakes were always clean enough.
I don´t want to take apart my intake manifold, so, there´s a way to clean the back of the valves on a TSI engine? my 1.4T getting close to 12k miles.
Elmo Villaseñor They make additives that slow down the buildup and help clean some of it off. Check out ATP AT-100. You add it to the vacuum line and it doesn’t result in smoke like CRC or other products do.
Humble, as always thanks for all wonderful insight and details. Getting ready to media blast (on your recommend) on the old b7 before I load her up with a new set of rs4 injectors.
I love this channel and Volkswagen! I’ve never had anything talk me out of getting an R let alone any Volkswagen though so I don’t know if they appreciate what my man Charles is doing.
Thank you
This is why I got rid of my tiguan, too much carbon build up and random missfires due to it.
This is super interesting... thanks for taking the time to open up the intake side on a virtually new engine.
I wonder... with DI fuel delivery, will there ever be a way to prevent this sort of build-up from happening? Unless you add manifold injection to your DI-engine (as some manufacturers are doing AFAIK), isn't this sort of behaviour "built into" the very concept of direct injection? All the cleaning properties of all the fuel and of all the V-Power additives in the world won't do you any good if the fuel never even touches the intake and intake valves ....
As always Charles - great video and very helpful.
If you haven’t seen this link, it is interesting to see how the EA888 engine actually seems to run on regular gas just as well as premium fuel. czcams.com/video/mN6Yz8I7Gyo/video.html
A friend of mine had this done recently on his 2008 Golf GTI. His direct injection system was pretty carboned up and not running well at all, it was similar to that of a GM spider Vortec injection system going bad. So he went ahead and had this procedure done on his car. I drove it back from the mechanics shop when we picked it up, ran pretty good after all was said and done.
I sometimes use a maglite through the sparkplug channel which can highlite the valves being fully closed prior to cleaning the ports. You can easily spot any signs of light between a partially closed valve & it's seat.
True, but that is tough to film to show you guys. :)
@@HumbleMechanic absolutely, wasn't being critical my friend, just adding a little to the thread, especially if any of your viewers were going to say that they filled the ports with cleaner & it all vanished! 😄
Wow, not what i would wan't my 10k mile engine looking like. I love Volkswagens but i think ill stick with my 2x MK2 Golfs.
Love my 91 Jetta coupe yoe ,and the 79 round eye diesel 😁 that's in 1000 pieces in the corner
@@MrTheHillfolk I own a 5-door 1987 pre facelift MK2 golf 1.6 with a Weber carb ,and a 3-door facelift 1988 MK2 golf GT 1.8 also with a Weber carb 😁 Both are great!
There's a part of me that's drawn to VWs and occasionally I think that maybe a Golf or a Jetta would be a good new car, but Charles does a pretty good job of bringing me back down to earth and remembering why I shouldn't do that. :D I'll stick with my '68 Beetle and if something like a Scirocco or a MkI or II Rabbit/Golf/Jetta comes my way I wouldn't say no, but other than that....
Direct injection is garbage other than marginal fuel efficiency which is sacrificed by users demanding more power and bigger, heavier vehicles. Change my mind. Sold my other car to buy a 1st gen Insight. 60 to 80 mpg, 995cc, 1800 lb, can go 400,000 to 800,000 miles without a rebuild.
@@VeritasEtAequitas Agree completely about GDI...that's why I'm either considering one of the handful of MPFI cars left on the market or restoring something older for my next daily driver to meet my rather modest needs
Great video... the zip ties, brush (both on a drill) and the scotch pad tips are excellent as a solution for the home mechanic who doesn't have access to walnut blasting machinery.
I haven’t even started the video yet but thank you for posting !
I would love to see you do a video on some of these additive products, specifically the Liqui Moly stuff. Would be interested in seeing pros and cons and if they really are even worth it.
B Fielder Project Farm style
This is Exactly why I have NOT bought a petrol direct injected engine yet. That 10k mile engine looks like a MPI engine with 120k miles
Honestly... I've seen 200k Honda D series engines with less carbon in the intake ports than this.
My '02 Audi A4 1.8T with 225k km has no carbon on the valves at all, literally. MPI with good gas (I use Shell V-Power) shouldn't have any carbon on the intake valves.
120K miles?
Oh you meant 320K miles, easy typo to make.
Amazing!!!!!!like allways!!!!!congratulations!!!!you are my idol....
Hey I’m a huge fan of the channel. I intern at a petroleum testing company and we do a lot of research on carbon buildup or carbon fouling it’s more commonly called. The first point I’d like to make is that brand of gasoline doesn’t make any difference when it comes to fouling and most of the claims but gas companies are BS. The second point is that I think tuning can lead to accelerated carbon fouling as tunes typically increase the AFR. One of the best ways to counteract this is to install a more powerful spark plug. Love the channel and thanks for all of the guides it made me confident enough to do maintenance on my alltrack rather than taking it to the mechanic
DUDE Great insight! I will be upgrading the plugs soon. Just don't want to spend $200 on plugs. HAHAH
HumbleMechanic no problem I’m loving the golf R so far and I noticed a typo in my original comment. Tunes normally decrease the AFR not increase it meaning you have an engine that runs richer than it was designed to.
You have a catch can installed on there too, right? Can't wait for the step by step. My Golf Wagon is probably due for this at 70k.
I dont see a catch can here. He installed one in the Tiguan of his wife a while back. czcams.com/video/1hvgwXKVdYw/video.html
Gen 3 pcv when working correctly doesn’t need a catch can. I’ve had one for 2 years and it’s been dry the whole time. It’s also bad for your seals, it’ll increase crankcase pressure
@@Irishluckily A catch can will not increase crankcase pressure, It is just a sepreator that you put in the vent-line that goes back to the intake
1kleineMax1 yeah it will, the line bottle necks. I installed it from pcv to the turbo inlet pipe. I know how it works. The only people who have had oil in their catchcans on the ea888 gen 3 either deleted the pcv or they had a failing one.
Anthony RS What do you mean by “line bottle necks”? The catch can is simply a chamber inline. Does nothing to crankcase pressure.
Gen 3’s still carb up the valves. I’ve done induction services on Gen 3’s a plenty. Plus look at this very video. Charle’s car has 10k miles, and the valves were sooted up nice!
@HumbleMechanic Do you think 🤔 stage 2 tune is contributing to the carbon buildup? (extra boost = extra blow by = extra crankcase gunk through the intake?)
Catch can time?
That is possible. Most of the miles were at just stage one or stock. But its possible.
That’s a good question? Forgot you have stage 2. I gotta hunch it might be
I would think the Italian tune up would help prevent the carbon build up by going with a stage 2. Looks like the carbon build up is simply just still an issue since we don't get dual port injection in the US. Sad...
SaraK There is no avoiding it then. Guess I will have to do some Italian tuning on my own VW
As common practice on DI engines, I always clean my cylinders every 30,000 miles. By that point it is pretty carboned up but BG and CDC products work really well at cleaning it out. I don't take my car to the track or work my engine nearly as hard, so that works well. My first DI engine on a 2008 Buick Enclave lasted with me over 150,000 miles with no problems. Still running for a second owner. Now own a 2018 Buick Envision also a DI engine, serviced at its first 30,000 miles with BG products it cleaned up the buildup well. Was curious to see how much build up on an engine at 10,000 miles so not surprised at some build up, but the degree it is there already. Thanks for sharing.
@humblemechanic great video. Looking forward to the next one. You took out all of the brush sounds. LOL.
Dang I meant to put some back in.
I dropped them to level out my audio. Then meant to put it back. Ahhaha DANG
But now I’m even more happy with the Instagram video
@@HumbleMechanic have you ever done this process on the 2.5 in the B7 Passat?
Converted my A3 8P TFSI to port injection. Good bye direct injection misery!
Now the test is if those “spray in the intake” carbon cleaners do anything.
Exactly
If they work, all the carbon gets into the cylinders then into the filters but if you use it like once a month may be ok
SHOPDAP.COM did one and it didn't really do a lot. Berrymans was the one they used.
Thank you for making this nice video surprise how carbon can get build-up this much even the car being taken good care of.
0w20 oil just evapotate almost like water and it is absorbed very easy by the pcv and thrown in the intake. Caratec doesn't do a thing and the petrol v power, is not sprayed in the right place. One more round of injectors, placed in the intake, eventually by the manufacturer, witch should work in a few driving regimes, as in long rides and highway or something like that ,would fix this problem for ever.
Thank you for this video, H.M. !
Was like gold! :)
Love hate relationship with all these GTIs man smh
life in plastic, its crack tastic . god if they could make the block out of plastic they would, as much as i love the mk7 once it goes past 250k or a a few years, id imagine its going straight to the junkyard :
Let's hope not LOL
All those plastic parts though are soon available as cheaper pattern parts, simply because of that. Even the dealers buy them as well, especially for older vehicles.
I say the only Golfs that's worth buying is the Diesel one :D no VW gasoline engines for me thanks...
they sure are lighter weight, though! Man when I pulled the dual-runner intake manifold off my Integra, even though it's aluminum, that thing was a BEAST!
@@Patrick94GSR better made though
I have a shop vac and I am looking at getting a air compressor so I will probably go the media blasting route just because it sounds like less of a pain in the ass.
While I am at it I want to say thank you. I have known about your channel for years, but I wasn't ready to jump in and start working on my car myself. As I have gotten more comfortable and realized that I actually did learn some things from those months at tech school before I dropped out because I was outclassed by people who had years of experience. I always planned to dive in and do my own maintenance at some point, and seeing how much a dealership wanted to charge for spark plugs along with my desire to bump up to stage 2 pushed me over the edge. I am hoping to put most of the supporting mods on myself, and after seeing these videos I am confident I can clean my car up since I am at 50k and I would like to make sure she is at her best for as long as I can.
A few years ago, my mom needed a car. We were lucky to find a 2011 Honda CRV, the last year the Honda CRV didn't have GDI.
CRC makes GDI intake cleaning spray that advertises that it is especially designed for GDI engines. However, you can use it on MPFI, TBI, and carb engines according to the bottle. I used it on an MPFI engine and it worked well.
My dad owns a 2017 Honda Fit. I told him that he needs to run injection cleaners because of how much more stress a GDI engine puts on injectors. He got the message.
Thanks to high EGR rates, I have heard that modern diesels get even dirtier.
Ridiculous considering how much development the engine has had over a century..and yet we get carbon buildup like this due to eco considerations..and not enough thoughtful engineering regarding this known problem..
Its vomit worthy when i see plastic intakes, or cam covers like on the c63 amgs!🤮
Hope you realize that plastic intakes have smoother runners than the casted aluminum ones. Also does not act as a heat sink for the motor
Why?
RIP SIC58 its not conducive to longevity , and has a heat cycle limit.
Charles thx for videos man. I was able to clean my intake valves, men these valves were dirty especially the air dividers. 👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾
awesome!
Good job Charles:):)
Thank you for 60FPS
Give it the beans? I'm calling Sarah N Tuned
LOL I got that from my dudes at Apex Tuning. Does Sarah say that too?
@@HumbleMechanic She does in all her car reviews, LOL
Lets give credit where credit is due....although the phrase has been around for a long time, Eric O is the youtuber who made it what it is today!
And as far as that carbon build up goes, I can think of another DR. O idiom..."Theres your problem lady"
she stole it from james may
Don't, a dude may show up.
Great video. Thank you.
Even with all the Extras you did,
Shocking.🇨🇦👍
VW - Proof that not all German engineering is *good* engineering.
DigBipper188 apparently European models do not have this problem but vw is made cheap in Mexico for the North American market I’m guessing they try to save every penny
Great video, looking forward to the intake removal/install video.
Any concerns about carbon deposits inside the combustion chamber? If the injectors are in the combustion chamber, and they looked dirty... I have a 2017 and at 27K I used a bore scope through the intake temp sensor hole and they looked similar to what I see in your video. I just used a can of CRC intake valve cleaner and sprayed it through the same temp sensor hole per the instructions. They cleaned up almost as good as yours, i posted some pics here: forums.vwvortex.com/showthread.php?6926800-What-did-you-do-to-your-Golf-R-today&p=113536637&viewfull=1#post113536637
Your comments and pictures are very useful, i appreciate that.
Been driving really short distances for the past year and done almost 3500 miles. It is time for my annual service (oil and oil filter change, air filter...) and
probably will use the CRC next year when i will be at hopefully 10000 miles.
BTW i own Tuscon 1.6 TGDI 6spd Manual.
Bravo. Nice presentation .
This video is fantastic 🤗👍
Water meth, will look like new after a few hundred k of spirited driving with that squirting :)
Why is no one talking about 0W-20?! When I heard that i huh’d like scooby doo
0W-20 is what most performance FI motors recommend and it's not an issue in terms of carbon build up,
oil dilution would be my biggest concern which can be mitigated by frequent oil changes or going to something like 5W30.
BigHeadClan not in the euro world. My main reason was because it’s the same engine as the last generation which takes 5w-40
@@Irishluckily BMW typically recommends 0W20 for their motors but I'm not sure about Mercedes. Either way the weight of oil can change depending on your location, recommended oil manufacturer and what type of oil you pick up by a small amount.
The most important is location however, up here in Canada we tend to recommend thinner oils for winter starts when it's -30 outside.
BigHeadClan yeah I’m in NH and drop down to 0W to be safe on coldstart when it’s that cold. Sounds better too lol
@@Irishluckily Hah yeah your pretty close to the boarder so you get similar weather, my roommate has a Mk6 GTI he runs almost exclusively 5w40.
He did try 5W30 this winter but was actually starting to develop some noise on cold-starts, swapped back to 5w40 and ran as normal.
So thinking his generation of motor was just very particular about oil weight.
Love this 🤬 video! Thanks!!!!!!
For the first time I’ve tackled the job of complete intake manifold replacement along with throttle body replacement (previous owner crash damage) & did a a full carbon clean at the same time. I found these humble mechanic tutorials very helpful in getting my head around the EA888, albeit with the additional factory multi-port injection rail setup in an Audi S1 with so little room in the engine bay, that the internal bonnet latch in the rad support panel needs to be removed just to clear the throttle body.
I’m still amazed at the carbon buildup from only 21,000 kms (13,050 miles) & I’m hoping the APR catch can setup & complete removal of the factory PCV setup (racecar-mandatory) will cut this excessive carbon buildup down in the future.
