Probably shouldn’t say this but I was a tech at Hyundai and we never replaced the combustion seals the o-rings. However, at the rail though we always did replace Hyundai never payed us enough to change those with warranty times
When I see the repairs from Ivan, Eric O and others I'm so glad I kept my trusty 23 year old Toyota Camry with a four cylinder gasoline engine with port injection. This car is a breeze to maintain. Repair so far is at 45 $US plus brake rotors and pads. But the exhaust system is beginning to leak. Well it's over 23 years old now so I have to bite the bullet... But I will never sell it. It runs smooth as silk! By the way I live in mid Sweden in the rust belt but my car has no rust. When I bought it (it was a second hand car one year old) I wanted a rust protection made with Mercasol. A product they use to protect the oil drilling stations in the north see. The rust protection is still sticky after 23 years now. A wax product similar the car manufacturers use when importing cars to the Nordic countries , a true rust belt area! PS! In Sweden Toyotas are not considered to have the best rust protection. The best rust protected cars are BMW, Audi And Mercedes. But as we know, they have other problems... BTW, I'm so impressed with Ivan. He is such a patient guy. Always enjoying his work !
I also have a 2006 Camry. I worry a little bit because it is the 4 cylinder 2AZ-FE engine which in the previous year was a notorious oil burner and in this year strips out head bolts. I just take good care of it and hope it lasts. My solution for rust is to not drive it in winter lol. I have a 1999 Honda CR-V as my winter beater car. I wish I had the fuel economy and power of these modern GDI cars but not the problems.
My 2000 4cyl Camry is at 340K miles and doing well. It still has the original exhaust as well as original engine, tranny, ac, front struts. I've updated it with LED headlights & android radio with 9inch screen - agreed, I would not get rid of mine for anything. Watching Ivan working on this Hyundai is nightmarish for its horrid maintenance and parts costs.
This job requires the patience of a saint! This over-engineered engine is totally service unfriendly, almost if designed to be serviceable by dealers only. Great job Ivan! That smoke looked like oil smoke, but it could be due to oil diluted with gas. Didn't expect a Part 3! Could there be some micro fuel leak into combustion chamber? Crazy!
When I did a carbon cleaning on my daughter's 2011 VW Tiguan, which is a GDI engine, I found a good workaround for the expensive factory style tooling. I used the tapered shaft of an awl to stretch the injector seal enough to get it on, then used a BIC pen cap to resize it back down to the correct size. It worked perfectly.
From my experience, most gdi injectors are made by only three companies. Denso,Bosch, Hitachi. They all seem to fail in the stuck open fashion. It makes it easy to diagnose, but really hard on the engine to process that much fuel. Great video! I picked up a kit off Amazon that does the same as your tools, but works for 95% of the gdi stuff out there.
Wow Ivan I had the 2009 Hyundai Santa Fe 4X4 for 5 years and not one hiccup, it ran like a dream my milage was 25 MPG in town and 32 Highway MPG, mine had only 1,200 miles on it when I bought it and with the 10 year 100,000 warranty and the 5-year bumper to bumper extended warranty I got right from the dealer with maintenance for life I never had to worry even about oil changes. In 5 years of ownership, I only had to put tires on it once in 5 years, they even changed my wiper blades every 6 months for FREE. I can honestly say their dealership was the best I had ever seen. And for me that's saying a lot I hate stealerships. lol This 2016 must be a lemon or Hyundai went down the tubes after 2010. Good job, hate to say it but the owner needs to have a priest exercise the demons out of this thing and sell it shortly after. lol
Seeing stuff like this makes me so happy I'm retired and I'm keeping my uber simple 2010 Ford Fusion 2.5L port injected "beast" as long as it is able to be repaired.
FYI for anyone in that intake valley doing some work, this (or another variant) V6 has an issue with a leaky oil pressure switch/sensor that sits below those rails and below that black tube, to the left over by the cam gears. When it leaks, the oil will often travel down the valley to where the block bolts to the transaxle, and will give the appearance of a leaking rear main seal. There is a bulletin out there about this too. Also note, this sensor will often push oil INSIDE the attached wiring (between the copper and insulation), and the affected wires lead around and up to the pass side front corner of the engine, where there are a few relays or electronics sitting on a bracket. The oil will look like it’s leaking out of the relays, and will be dripping down on the serpentine belt and other rotating assemblies, and thereafter all over that side of the engine. Before you attempt this work, check with Hyundai about it being covered under warranty. They have been extending it to cover this issue.
Be careful with that oil change Ivan I remember changing the oil in an 80s bronco 2 this guy never let warm up and he drove less than a mile a day. I used to pick on him saying the closest the windshield ever got to being defrosted was a little circle made with his nasty cigar🤢 and they were nasty. So when I went to pull the oil plug to drain the oil there was so much pressure the plug blew out of my hand the oil hit the drain pan on the floor splashed and hit the old school drop light bulb it popped and the fireworks started the oil/fuel started on fire 😬 and I believe To this day I hold the world wide fastest creeper speed record for getting out from under a vehicle and grabbing and deploying a fire extinguisher 😁 I got the fire out quickly and nothing was damaged but maybe my coworkers underwear while they were running away 🤣 Be careful Ivan.
@@PineHollowAutoDiagnostics Yes it was I was lucky but fires in that body shop were guite common with all the welding and flammable liquids and rags people sometimes weren't to careful with so I was usually Johnny on the spot with the fire extinguisher. 😁👍 I don't how many fires I put out.
I have a 2017 Santa Fe XL, bought new, with the 3.3L V6, so watching this was of interest to me. I run the CRC intake cleaner about every second year, and at 76k Km (47k Miles), I frequently get 7.4 L/100Km highway (Canada, eh!) or 32mpg US.
Any vehicle with GDI will have a build up on the intake valves. That is one of the problems with GDI, the injectors are no longer spraying fuel on the valves to clean the valve faces. You just showed us the reason to really consider an oil catch can. My new Edge has both GDI and port injection to help with this problem. (Also installed an oil catch can, you would be amazed on the amount of oil goes through the PVC system)
Nice work Ivan, One thing for sure is get ready for ALOT more work like this in the near Future from all brands, Thanks to the EPAs strick Regulations. I'm personally staying away from GDI-Turbo charged Vehicle's, Even though my wife's car was built 9-21, No GDI no Turbo and no CVT, Getting a overall 37.2 mpgs at 29.000miles, The crazy thing is if I use none Ethanol 87 octane it will get 44+ MPG cruising at 62 mph but it's not as hilly here as where you live, I know because I grew up in a small town called Vicksburg PA, Almost straight EAST from State College, Me now Wisconsin much COLDER 🥶. The Car 2020 Civic Sport Sedan 6speed manual K20C2 engine. Why because as a Mechanic I hate working on my own shit on my days off. I'm not talking about oil changes, talking about the work you're doing for a Customer, It's not a preventable problem unless of course You don't buy something like this in the first place, But in the other hand allows for Good You Tube content, Keep rocking it.👍
I got rid of my daughter's Hyndia a few years ago. As soon as fuel press. Mis fires and other issues arised. I traded it in for a 2014 Toyota 4 runner. My daughter loves it. At this time. There are no issues. My 03 Chevy 4.8 is at 365k now. Still on its original 🐱. Original fuel injectors. I did install new o2 sensors bank 1s. The rear o2 sensors are still original. Original automatic trans. It's beginning to shift rough. I think it's the valve body sticking. Last week I pulled my front diff. Installed new cv inner bearings on the diff. New CV axle seals. They were leaking bad. New rear diff pinion seal. New transfer case output shaft seal. Drained front and rear diff with new fluid. Drained and refilled transfer case fluid. Lubed the chassis. New front timing cover seal. Took me about 2.5 days crawling around under my truck. I'm a true shade tree DYI. I do my own work. Cheers to you Ivan for taking on a task. I possibly could do it with the correct tools. I'm about to tackle a 2010 taurus engine swap. 😄 I'm 68 old fart. Still wrenching. I just like working on mostky anything. Because I cannot afford paying someone to do it. I'm a DYI of many trades and master on NONE.😄
Great work. I had a 2017 Elantra, my son now owns, now has over 100,000 miles, no probs apart from failed ignition coil, cheap fix, $80 from Autozone. Great gas mileage but I know it will have nowhere near the longevity of a Corolla, but then again I only paid $11,000 from a main dealer when it was only 18 months old. I then went and bought a 2004 4WD Sequoia, paid only $4000 and had 154,000 miles. 18 mpg but who cares, at least I will not have stupid failures like on this Hyundai and I could buy a LOT of gas with the money this customer has shelled out just in the last 6 months. Also my Sequoia will easily reach 400,000 miles and parts are plentiful and is so easy to work on but in truth all I do is change the oil and filter. Timing belt was the only big thing but the kit was only $200. Gona keep my Sequoia forever, removed the rear seats, great for leisure and utility and the power window in the hatch is very useful to have. Without question older cars were made better than new.
This Hyundai is interesting. I have seen plenty of these Kia/Hyundai 3.3 V6 vehicles go well into the 200k mile range with very few issues. I know someone that has a 2015 Kia Sorento 3.3 that has been badly abused with maintenance, and it currently has 210k miles with no engine issues. I guess this could just be one of those bad luck cases, but this isn't the norm for these V6 engines.
I saw a video of someone installjng these injector seals the DIY way. Stretch them out with a tapered metal rod, install on injector, push a rubber fuel hose over it and tighten it down with a hose clamp to resquish the seal.
I also cleaned the intake valves on a Mercedes M270 myself. The biggest issue was taking the intake manifold off, which is between the engine and firewall. Then used spray EGR cleaner, let it dissolve the carbon, used zipties to scrub more off, and blew out the gunk with compressed air. They weren't spotless, but they were pretty darn clean. It's called the ziptie method, look it up. By the way, I did this as part of the procedure to replace the thermostat, which is squeezed on the lower side on the back of the engine, and can only be accessed by removing the intake manifold. It's some crazy german engineering plastic ball valve with a thermostat controlling it and a computer controlled heater override. It has 5 or 6 hoses going to it. Fun for your back while you lay on top of the engine.
Ivan, you asked if I was sure I wanted to buy one of these? Of course, I would! I am just thinking of all that gas I would save and all of that traction I would get in the snow. Especially after blowing by all of them with the old Mercury in the winter.
The crickets seem to enjoy your work! Seems like a very difficult - heart stopping repair for the do-it-yourselfer. Thanks Ivan for the upload! Not sure we as consumers have much choice anymore with vehicles and direct injection. Most everything has it. Unless you want to drive a 90's vehicle or an early 2000's. Are Kia/Hyundai just more problematic?
Yeah that thing is a clinger! Sad to say but I think your married to it, till the owner let's it go. But I also think you've done a stellar job thus far. I'm sure your customer is more than happy with your work and communication. Unfortunately looking forward to part 3. Keep up the good work Ivan!
Those are Teflon seals like they use on ac compressors and transmissions. One tip is to lube the sizing tool and seal with oil to aid with installation
I'm very surprised that there's no lubrication used on those o-rings. When I changed the cartridge on my shower valve, I had to use it to prevent rolling or damaging the o-ring and that's just 60psi. GDI is way higher.
Same procedure for a BMW N54 or N55 injectors that is a sizing tool and it has cone shape internal to achieve the correct compression of combustion seals after instalation those seals expand somewhat to achieve the correct clearances ..Ivan I enjoy watching you are truly talented and very knowledgeable
When experience speaks "Sell that car", ppl can either listen or they can feel (wallet). Experience speaks, wisdom listens. You can learn through your eyes and ears, or through pain. Stay gold.
I rented one of these in Chicago a few years with the 4 cylinder engine. Driving around on city streets I was quite impressed. I drove it to Detroit, on the freeway around 70, that 4 banger had the buzz and boom of an old Corolla, it was intolerable to me. I think I will stick with my Toyota Highlander.
Ivan your expression at 10:08, I hear you buddy,,,,, it's the gift that keeps on giving. Compression reaming/sizing combustion seals made from a type of plastic, interesting.
Ivan, great job. Once again you've demonstrated the patience of Job, nerves of steel, and real genuine tenacity. Glade you ended Part 2 with major success. Looking forward to Part 3 and watching you ship it down the road! Thanks for Sharing!
2012 Sonata 2.0t owner here. Engine threw a rod. Dealer installed new long block engine under warranty. Gave no warning at all. Always maintained. I even changed the oil early everytime! This is just the way it is with modern cars. Throw aways
nice job .. i am surprised you didn't try to sell a intake valve cleaning job ...i know on most german cars dirty intake valves cause miss fire codes ..as always well done
I am no KIA/HYUNDAI fan. My wife and I had one and it was crap. I know several people as well that have had super serious issues with them. My wife's one coworker had her Sante Fe just die on a long road trip to a wedding. The engine was cooked. I don't care what anybody says but i swear by Toyota. I just drove over 1400 kms to my remote camp with my Tundra and not one issue at all.
Hyundai tech here, not sure if you live in a cold environment, but those oil filter housings also fail once it starts to get cold, and you'll have to remove both of those fuel rails just to do it.
Hi Ivan. Bottom injector seals are possibly teflon or some other plastic that can handle the higher temps in the heads near the combustion chambers which is a much hotter environment than the fuel rail side of the injectors.
It took me awhile, but after listening extensively to the video's music track, I finally recognized the music group, it is the "Crickets" who debuted in the early 1970's... I'm sure of it.
Whew! Another work-out for my technically deficient left-brain. And then you make inspired intuitive leaps on top of everything, like spreading the combustion seals across the remaining injectors, one out of two (just in case). Love it!
love your videos. reason to not get gdi car, except all new are, at least get (like this video) an NA v6 or il4 engined car w no turbo so in addition to shown issues you also don't have worse carboning/stuck piston oil sealing rings that turbos make worse by additional pcv gasses created, my 2c anyway. awesome informative vids.
I’ve never had any issues reusing those Teflon seals. I know it’s the right way to do it but the oil pressure switches are famous for leaking in those engines and I’ve done quite a few without replacing seals.
Another great video! The fact that both fuel rails had to come off means that you get full use on the first time of the tool you had to purchase just to do the job.
Fine Business Ivan! About 14 or 15 min. into this vid. you have crickets chirping.I first thought it was the auger failing on my pellet stove!!! CHEERS from HERE!
I seen "watch we work" do these on a 2015 Silverado, and he ended up breaking some of the injectors and had to buy new one's. He ended up having to do the job 3 times. I think the injectors were breaking when he pulled them out of the engine, not exactly sure. Hope you have better luck with these
I rebuilt a 4L60 transmission in my sons Silverado and it also has seals that have to be slipped on then resized to put the shaft back in the hole. Same procedure just larger tools
I guess you probably should have walnut blasted the intake valves since you had everything off. Seems like the GDI engines need a lot of additional maintenance. I guess it’s probably a 100,000 mile service to put injectors and coil packs on. The background noises sound more like jungle than Pennsylvania to me. 😂😂
I dont know if you will see this comment but when i do gm injectors i just use a new razor blade and cut the old seal then peel them off. GM injectors come pre sized so the tool is not required on the new injector.
Also you can, if you already not did to ask owner because everything on you way is out to clean that intake valves chambers and that injectors with solvents and ultrasound bath. And...maybe bigger problem if that injector are stuck with debris from hi pressure fuel pump.
Hi Ivan, That was some procedure needed to replace one injector. Doesn't bode well for Subaru GDI engines. I hope in part 3 you can solve all the problems. You and your family stay safe.
18:00 Combustion seals are typically PTFE (Teflon) 30:45 Injectors in my 3.5 EcoBoost went >240k miles and the only reason I replaced them was because I had high fuel dilution (2.3%) on an oil analysis, No drivability issues or smoke, so probably could've held off on replacing them. I think Ford OEM are Bosch injectors. I didn't catch, who was Hyundai's OEM?
Really enjoying watching this problem solving. Noted your comment on preference for older cars. Must say I have come to the same conclusion. I had a 1998 LX470 which was perfection with very bad fuel economy otherwise the 2005 to 2010 seem the years with appropriate levels of engine tech to me.
Owned an 89 1.4 manual Hyundai I bought used with 60,000 miles in 98. I put another 65,000 miles on it before getting rear ended at a traffic light. All I did when I bought it was mount new tires/alignment, brakes (easiest brakes I ever installed), and normal maintenance (oil changes, etc...). When it was totaled it ran as good as the day I bought it (paid $700)! It's amazing how all these car manufacturers sink gobs of money into researching how to screw the consumer in the least obvious way possible, at the exact time the warranty expires! And it isn't exclusive to Hyundai.
That’s a loud cricket 🦗 lol. One time I was sleeping. This loud ass cricket wake me up. It was so loud. I’m deaf lol. Next day I found it in my bathroom lol. Nicely job. It does look difficult job. Impressive.
I suppose I should trust you’re doing it correctly, but it seems to me that using that swaging tool to install the new seals, some lube might help, and not reversing the direction of rotation during removal.
I recently bought a 2023 Tucson with GDI, previously i had a 2017, 2019 Elantra GDI and 2021 Forte with GDI, all the vehicles had below 30K but i hope any potential issues are covered under warranty, dealer techs probably not worth shining your work boots to be honest. 130,000 miles? You could easily be the head of a shop telling others what to replace when needed, nice job. Not sure what's worse? New vehicles like that that get 30 mpg then need expensive repairs down the road or my former winter vehicle, a 1996 Grand Cherokee 5.2 that got 12 mpg, either way the owner pays.
my versa note has 8 injectors on my 4 cylinder . At first I thought it was port and direct injected but that's false . It turns out it has 1 injector for each intake valve which is interesting but still better than direct injected!!
Those are PTFE. I’ve seen rear main seals & valve stem seals use a similar type of tool for installing PTFE seals. They are great seals, but easily damaged if not installed perfectly.
I hope customer will stop pushing luck driving this car when "MIL" comes on. Definately "mickey mouse" design, sizing plastic seals instead of just making them the proper size, especially that coolant passage dead headed with rubber piece🤣. Dry ice blaster would be handy as a part of this job. Great video as usual man!
That process is swaging them onto the injector so that they compress and form a tight grip on the injector. What would be better is if the new injectors came with the seals already installed and swaged.
Facing exactly the same issue, I can understand. My engine oil is smelling like gas, getting bank1, multiple misfires, faulty fuel injection and domino effect
I really am surprised the cats didn't blow apart! I've seen them destroyed by single cylinder misfires on port injected engines, in less than 1000 miles!
Sounds like you’re working pretty late into the evening, we hear that here up in the Pocono’s as well, very relaxing… unless you’re working on a Hyundai of course! Lol
I don't know if you did or know but, the high pressure fuel pipes for the gdi system need to be replaced every time you remove them. I have seen them leak if not. Food for thought.
Ha. I was watching this video while the crickets were chirping out my window. Your track also has crickets chirping. I found out when I` carried my laptop into another room while watching.
Better just to replace all the injectors. I know it’s expensive but you get new seals with them, already installed. You know how it is: when one goes bad, they all go bad.
Wow, that's real pain in the ass to fancy tool to do the combustion seals! Im glad i don't own gdi!! You sure have the patience for doing them! Hopefully it'll last long time, same for the other original injectors as well. But i think you should have offered to clean the valves while you're in there! So that engine will last longer. Overall, great teardown and reassembly!! Let's see part 3!!
I purchased an elantra with a blown head gasket. When I removed the head it was not warped!? So I was like what happened, after installing everything back (new parts) car was misfiring, removed sparkplugs and just by accident my dad cranked the engine and I saw gas vapor just shooting out cilinder 3, injector was stuck open, and I think this caused the damage in the head gasket! found a 16k mile complete rail, had to definitely replace the Teflon seals, had a very hard time finding the proper ones, I called several dealers and they told me they reinstall the injectors with the old seals! that is crazy! , service manual says do not do this!
Great video, Ivan! GDI is just a bad idea in consumer every day drivers. I see where Toyota has started running a combination of GDI and port injection. Good idea to wash the valves, but now you have two fuel injector systems, one high pressure and one low pressure being made to play nice together by the ECM. Nothing could go wrong there, right?
The GDI engine with carbon buildup and oil burning, constant engine ping up hills. Hyundai is good for the 5 year 60k bumper to bumper warranty and after that get rid of them. Just my experiences.
Those seals seem to be Teflon like the ones used in transmissions. They're the only ones I've ever seen that are "resizeable" but easily cut or damaged. Very similar tools on transmissions, just bigger versions. Typically used used on the stator shafts for pumps or input shafts, etc. I've only done Honda GDI so far, no fancy tools required except for maybe a puller tool because in GDI they have a tendency to get stuck in the block.... due to carbon or whatever. Also, in an ATG class with Kris Lewis, found out that carbon build-up isn't directly due to lack of fuel washing it... but it is directly connected to PCV system. I won't go into detail here, so his paid class info isn't given away. Next time I see ya, I'll share.
@@dans_Learning_Curve not much. but if you buy a Toyota, they have a system that has both direct and port injection. Takes care of this problem. And some others. Depending on the situation it could run one system, the other, or even both simultaneously. And it's much quieter at idle
Right now there are Hyundai dealer mechanics sitting back chuckling with thoughts of "and now you understand my pain".
Probably shouldn’t say this but I was a tech at Hyundai and we never replaced the combustion seals the o-rings. However, at the rail though we always did replace Hyundai never payed us enough to change those with warranty times

When I did a carbon cleaning on my daughter's 2011 VW Tiguan, which is a GDI engine, I found a good workaround for the expensive factory style tooling.

I have a 2017 Santa Fe XL, bought new, with the 3.3L V6, so watching this was of interest to me. I run the CRC intake cleaner about every second year, and at 76k Km (47k Miles), I frequently get 7.4 L/100Km highway (Canada, eh!) or 32mpg US.
Kudos to you for even taking on that job. Once I saw that service info, I'm punting that job.
Always good to know you're replacing the correct part. I recommend replacing the complete car ASAP. :)
As in "correct part" = "complete car"? Got it! Heh-heh-he...
That tool is a miniature version of the one that you use to install the pressure seals in an automatic transmission.
Exactly what I was thinking. Probably made of Teflon.
Yeah I had to buy one to rebuild the 4l60e in my Camaro.
Any vehicle with GDI will have a build up on the intake valves. That is one of the problems with GDI, the injectors are no longer spraying fuel on the valves to clean the valve faces. You just showed us the reason to really consider an oil catch can. My new Edge has both GDI and port injection to help with this problem. (Also installed an oil catch can, you would be amazed on the amount of oil goes through the PVC system)
Nice work Ivan, One thing for sure is get ready for ALOT more work like this in the near Future from all brands, Thanks to the EPAs strick Regulations. I'm personally staying away from GDI-Turbo charged Vehicle's, Even though my wife's car was built 9-21, No GDI no Turbo and no CVT, Getting a overall 37.2 mpgs at 29.000miles, The crazy thing is if I use none Ethanol 87 octane it will get 44+ MPG cruising at 62 mph but it's not as hilly here as where you live, I know because I grew up in a small town called Vicksburg PA, Almost straight EAST from State College, Me now Wisconsin much COLDER 🥶. The Car 2020 Civic Sport Sedan 6speed manual K20C2 engine. Why because as a Mechanic I hate working on my own shit on my days off. I'm not talking about oil changes, talking about the work you're doing for a Customer, It's not a preventable problem unless of course You don't buy something like this in the first place, But in the other hand allows for Good You Tube content, Keep rocking it.👍
Ivan,
Great video series/job - thank you!
Seals are PTFE (Teflon). Very little elasticity but will cold flow under temp/pressure.

I got rid of my daughter's Hyndia a few years ago. As soon as fuel press. Mis fires and other issues arised. I traded it in for a 2014 Toyota 4 runner. My daughter loves it. At this time. There are no issues.
My 03 Chevy 4.8 is at 365k now. Still on its original 🐱. Original fuel injectors. I did install new o2 sensors bank 1s. The rear o2 sensors are still original. Original automatic trans. It's beginning to shift rough. I think it's the valve body sticking.
Last week I pulled my front diff. Installed new cv inner bearings on the diff. New CV axle seals. They were leaking bad. New rear diff pinion seal. New transfer case output shaft seal.
Drained front and rear diff with new fluid. Drained and refilled transfer case fluid. Lubed the chassis. New front timing cover seal. Took me about 2.5 days crawling around under my truck. I'm a true shade tree DYI. I do my own work. Cheers to you Ivan for taking on a task. I possibly could do it with the correct tools.
I'm about to tackle a 2010 taurus engine swap. 😄
I'm 68 old fart. Still wrenching.
I just like working on mostky anything. Because I cannot afford paying someone to do it. I'm a DYI of many trades and master on NONE.😄
Great work. I had a 2017 Elantra, my son now owns, now has over 100,000 miles, no probs apart from failed ignition coil, cheap fix, $80 from Autozone. Great gas mileage but I know it will have nowhere near the longevity of a Corolla, but then again I only paid $11,000 from a main dealer when it was only 18 months old. I then went and bought a 2004 4WD Sequoia, paid only $4000 and had 154,000 miles. 18 mpg but who cares, at least I will not have stupid failures like on this Hyundai and I could buy a LOT of gas with the money this customer has shelled out just in the last 6 months. Also my Sequoia will easily reach 400,000 miles and parts are plentiful and is so easy to work on but in truth all I do is change the oil and filter. Timing belt was the only big thing but the kit was only $200. Gona keep my Sequoia forever, removed the rear seats, great for leisure and utility and the power window in the hatch is very useful to have. Without question older cars were made better than new.
This Hyundai is interesting. I have seen plenty of these Kia/Hyundai 3.3 V6 vehicles go well into the 200k mile range with very few issues. I know someone that has a 2015 Kia Sorento 3.3 that has been badly abused with maintenance, and it currently has 210k miles with no engine issues. I guess this could just be one of those bad luck cases, but this isn't the norm for these V6 engines.
In a live stream a bit back when asked most reliable modern cars, Keith D. said Hyundai/Kia and Subaru and it didn't seem like he was being sarcastic.
I saw a video of someone installjng these injector seals the DIY way. Stretch them out with a tapered metal rod, install on injector, push a rubber fuel hose over it and tighten it down with a hose clamp to resquish the seal.
I also cleaned the intake valves on a Mercedes M270 myself. The biggest issue was taking the intake manifold off, which is between the engine and firewall. Then used spray EGR cleaner, let it dissolve the carbon, used zipties to scrub more off, and blew out the gunk with compressed air. They weren't spotless, but they were pretty darn clean. It's called the ziptie method, look it up. By the way, I did this as part of the procedure to replace the thermostat, which is squeezed on the lower side on the back of the engine, and can only be accessed by removing the intake manifold. It's some crazy german engineering plastic ball valve with a thermostat controlling it and a computer controlled heater override. It has 5 or 6 hoses going to it. Fun for your back while you lay on top of the engine.
Ivan, you asked if I was sure I wanted to buy one of these? Of course, I would! I am just thinking of all that gas I would save and all of that traction I would get in the snow. Especially after blowing by all of them with the old Mercury in the winter.
The crickets seem to enjoy your work! Seems like a very difficult - heart stopping repair for the do-it-yourselfer. Thanks Ivan for the upload! Not sure we as consumers have much choice anymore with vehicles and direct injection. Most everything has it. Unless you want to drive a 90's vehicle or an early 2000's. Are Kia/Hyundai just more problematic?
toyota gdi systems are the best ..they had gdi injectors and port injectors to keep the intake valves clean ...
I LOVE ❤ the crickets. Their beautiful music may be what helps to keep PHAD calm when annoying cars like this one want to put up a fight.
This particular failure doesn't seem very common. Don't think I've heard of a GDI injector failure in a Hyundai or Kia before.
Yeah that thing is a clinger! Sad to say but I think your married to it, till the owner let's it go. But I also think you've done a stellar job thus far. I'm sure your customer is more than happy with your work and communication. Unfortunately looking forward to part 3.
Keep up the good work Ivan!
I was cringing when you were struggling with the combustion seals. This is the sort of situation I sometimes find myself in.
Those are Teflon seals like they use on ac compressors and transmissions. One tip is to lube the sizing tool and seal with oil to aid with installation
I'm very surprised that there's no lubrication used on those o-rings. When I changed the cartridge on my shower valve, I had to use it to prevent rolling or damaging the o-ring and that's just 60psi. GDI is way higher.
That thing would not remain in my ownership after that debacle.
Same procedure for a BMW N54 or N55 injectors that is a sizing tool and it has cone shape internal to achieve the correct compression of combustion seals after instalation those seals expand somewhat to achieve the correct clearances ..Ivan I enjoy watching you are truly talented and very knowledgeable
When experience speaks "Sell that car", ppl can either listen or they can feel (wallet).
Experience speaks, wisdom listens. You can learn through your eyes and ears, or through pain.
Stay gold.
Ivan I can’t wait for the P0507 video I was actually dealing with this on a 2008 GMC envoy! Great video as always! Looking forward to the next video!!
I rented one of these in Chicago a few years with the 4 cylinder engine. Driving around on city streets I was quite impressed. I drove it to Detroit, on the freeway around 70, that 4 banger had the buzz and boom of an old Corolla, it was intolerable to me. I think I will stick with my Toyota Highlander.
Ivan your expression at 10:08, I hear you buddy,,,,, it's the gift that keeps on giving. Compression reaming/sizing combustion seals made from a type of plastic, interesting.
Ivan, great job. Once again you've demonstrated the patience of Job, nerves of steel, and real genuine tenacity. Glade you ended Part 2 with major success. Looking forward to Part 3 and watching you ship it down the road! Thanks for Sharing!
2012 Sonata 2.0t owner here. Engine threw a rod. Dealer installed new long block engine under warranty. Gave no warning at all. Always maintained. I even changed the oil early everytime! This is just the way it is with modern cars. Throw aways
nice job .. i am surprised you didn't try to sell a intake valve cleaning job ...i know on most german cars dirty intake valves cause miss fire codes ..as always well done
I am no KIA/HYUNDAI fan. My wife and I had one and it was crap. I know several people as well that have had super serious issues with them. My wife's one coworker had her Sante Fe just die on a long road trip to a wedding. The engine was cooked. I don't care what anybody says but i swear by Toyota. I just drove over 1400 kms to my remote camp with my Tundra and not one issue at all.
Hyundai tech here, not sure if you live in a cold environment, but those oil filter housings also fail once it starts to get cold, and you'll have to remove both of those fuel rails just to do it.
Wow thank you for the tip! Sounds like a Chrysler Pentastar haha
Hi Ivan. Bottom injector seals are possibly teflon or some other plastic that can handle the higher temps in the heads near the combustion chambers which is a much hotter environment than the fuel rail side of the injectors.
It took me awhile, but after listening extensively to the video's music track, I finally recognized the music group, it is the "Crickets" who debuted in the early 1970's... I'm sure of it.
Whew! Another work-out for my technically deficient left-brain.
And then you make inspired intuitive leaps on top of everything, like spreading the combustion seals across the remaining injectors, one out of two (just in case). Love it!
love your videos. reason to not get gdi car, except all new are, at least get (like this video) an NA v6 or il4 engined car w no turbo so in addition to shown issues you also don't have worse carboning/stuck piston oil sealing rings that turbos make worse by additional pcv gasses created, my 2c anyway. awesome informative vids.
If the owner is smart, he will sell it after this repair. Great job Ivan.
Late night with Ivan..love the cricket backup vocals!!😁🇨🇦👍
I’ve never had any issues reusing those Teflon seals. I know it’s the right way to do it but the oil pressure switches are famous for leaking in those engines and I’ve done quite a few without replacing seals.
Another great video! The fact that both fuel rails had to come off means that you get full use on the first time of the tool you had to purchase just to do the job.
Fine Business Ivan! About 14 or 15 min. into this vid. you have crickets chirping.I first thought it was the auger failing on my pellet stove!!! CHEERS from HERE!
Excellent job. You are very brave for taking on such tough challenges.💪
I seen "watch we work" do these on a 2015 Silverado, and he ended up breaking some of the injectors and had to buy new one's. He ended up having to do the job 3 times. I think the injectors were breaking when he pulled them out of the engine, not exactly sure. Hope you have better luck with these
My dad has a 2.7 v6 Kia from 2006. Runs like champ. No problems at all.
I just picked up a 2006 Tucson 4WD 2.7 V6 with 226k miles for $300. Was neglected but actually drove to my shop with no exhaust haha
@@PineHollowAutoDiagnostics very good engines. Check the crankshaft pully. Sometimes rubber comes off.
I rebuilt a 4L60 transmission in my sons Silverado and it also has seals that have to be slipped on then resized to put the shaft back in the hole. Same procedure just larger tools
I guess you probably should have walnut blasted the intake valves since you had everything off. Seems like the GDI engines need a lot of additional maintenance. I guess it’s probably a 100,000 mile service to put injectors and coil packs on.
The background noises sound more like jungle than Pennsylvania to me. 😂😂
I dont know if you will see this comment but when i do gm injectors i just use a new razor blade and cut the old seal then peel them off. GM injectors come pre sized so the tool is not required on the new injector.
**cough,cough."fresh air"...love it
Great Video! TY Ivan! .....How'd you get the scar on your arm?
Also you can, if you already not did to ask owner because everything on you way is out to clean that intake valves chambers and that injectors with solvents and ultrasound bath. And...maybe bigger problem if that injector are stuck with debris from hi pressure fuel pump.
Hi Ivan,
That was some procedure needed to replace one injector. Doesn't bode well for Subaru GDI engines. I hope in part 3 you can solve all the problems. You and your family stay safe.
18:00 Combustion seals are typically PTFE (Teflon)
30:45 Injectors in my 3.5 EcoBoost went >240k miles and the only reason I replaced them was because I had high fuel dilution (2.3%) on an oil analysis, No drivability issues or smoke, so probably could've held off on replacing them. I think Ford OEM are Bosch injectors. I didn't catch, who was Hyundai's OEM?
Really enjoying watching this problem solving. Noted your comment on preference for older cars. Must say I have come to the same conclusion. I had a 1998 LX470 which was perfection with very bad fuel economy otherwise the 2005 to 2010 seem the years with appropriate levels of engine tech to me.
Owned an 89 1.4 manual Hyundai I bought used with 60,000 miles in 98. I put another 65,000 miles on it before getting rear ended at a traffic light. All I did when I bought it was mount new tires/alignment, brakes (easiest brakes I ever installed), and normal maintenance (oil changes, etc...). When it was totaled it ran as good as the day I bought it (paid $700)! It's amazing how all these car manufacturers sink gobs of money into researching how to screw the consumer in the least obvious way possible, at the exact time the warranty expires! And it isn't exclusive to Hyundai.
Nice job Ivan, thanks for this series it was very interesting!
That’s a loud cricket 🦗 lol. One time I was sleeping. This loud ass cricket wake me up. It was so loud. I’m deaf lol. Next day I found it in my bathroom lol. Nicely job. It does look difficult job. Impressive.
It is a swage block . You will swage the sealing ring into the groove .
Like the crickets in the background.
I suppose I should trust you’re doing it correctly, but it seems to me that using that swaging tool to install the new seals, some lube might help, and not reversing the direction of rotation during removal.
I followed the OEM instructions. No lube.
Like the white teflon pressure seals of the input shaft on a automatic transmission.
It occurs to me Hyundai knew that this engine was going to be prohibitively expensive to service and put it into production anyway
Guaranteed service dept income stream.after the 10/10k warranty is gone..
It occurs to me that your comment makes no sense. The greatest expense is in the labor, not the parts. Hyundai makes no money from the labor.
They are all expensive to day to work on.
I recently bought a 2023 Tucson with GDI, previously i had a 2017, 2019 Elantra GDI and 2021 Forte with GDI, all the vehicles had below 30K but i hope any potential issues are covered under warranty, dealer techs probably not worth shining your work boots to be honest. 130,000 miles? You could easily be the head of a shop telling others what to replace when needed, nice job.
Not sure what's worse? New vehicles like that that get 30 mpg then need expensive repairs down the road or my former winter vehicle, a 1996 Grand Cherokee 5.2 that got 12 mpg, either way the owner pays.
my versa note has 8 injectors on my 4 cylinder . At first I thought it was port and direct injected but that's false . It turns out it has 1 injector for each intake valve which is interesting but still better than direct injected!!
Wow that's nuts never seen that before lol
Wes had a Chevy with fuel injector issues. He replaced one and the problem kept moving. He was not a happy bunny and ended up firing the parts cannon.
Can't believe that the seal installation tools were $100 for a few little plastic pieces !! That's crazy !
Those are PTFE. I’ve seen rear main seals & valve stem seals use a similar type of tool for installing PTFE seals. They are great seals, but easily damaged if not installed perfectly.
I used to work with a tech that didn't replace the injector seals , I thought he was crazy to do so but to my knowledge , never had an issue.
I drive a 2008 Toyota Yaris. Rides like a go-cart.... but 200K runs and runs, 40 MPH. I'll keep.
This was an awesome video Ivan, dang so impressed with this difficult job!
It fixed the problem but now the trust in this vehicle is in the toilet haha
That oil buildup on the intake valves is courtesy of emission controls.
I hope customer will stop pushing luck driving this car when "MIL" comes on. Definately "mickey mouse" design, sizing plastic seals instead of just making them the proper size, especially that coolant passage dead headed with rubber piece🤣. Dry ice blaster would be handy as a part of this job. Great video as usual man!
That process is swaging them onto the injector so that they compress and form a tight grip on the injector. What would be better is if the new injectors came with the seals already installed and swaged.
Facing exactly the same issue, I can understand. My engine oil is smelling like gas, getting bank1, multiple misfires, faulty fuel injection and domino effect
I really am surprised the cats didn't blow apart! I've seen them destroyed by single cylinder misfires on port injected engines, in less than 1000 miles!
Sounds like you’re working pretty late into the evening, we hear that here up in the Pocono’s as well, very relaxing… unless you’re working on a Hyundai of course! Lol
I don't know if you did or know but, the high pressure fuel pipes for the gdi system need to be replaced every time you remove them. I have seen them leak if not. Food for thought.
That's what the OEM info says...REPLACE EVERYTHING haha
Ha. I was watching this video while the crickets were chirping out my window. Your track also has crickets chirping. I found out when I` carried my laptop into another room while watching.
Better just to replace all the injectors. I know it’s expensive but you get new seals with them, already installed. You know how it is: when one goes bad, they all go bad.
C'mon Ivan just do the Ol Scotty Kilmer Cat cleaning!! 🤣🤣 Great stuff as always
What do I think? Skip Hyundai. Great video! Very interested in part 3…
Wow, that's real pain in the ass to fancy tool to do the combustion seals! Im glad i don't own gdi!! You sure have the patience for doing them! Hopefully it'll last long time, same for the other original injectors as well. But i think you should have offered to clean the valves while you're in there! So that engine will last longer. Overall, great teardown and reassembly!! Let's see part 3!!
Never got the chance to work on a direct injected vehicle. Thanks for the video.
I purchased an elantra with a blown head gasket. When I removed the head it was not warped!? So I was like what happened, after installing everything back (new parts) car was misfiring, removed sparkplugs and just by accident my dad cranked the engine and I saw gas vapor just shooting out cilinder 3, injector was stuck open, and I think this caused the damage in the head gasket! found a 16k mile complete rail, had to definitely replace the Teflon seals, had a very hard time finding the proper ones, I called several dealers and they told me they reinstall the injectors with the old seals! that is crazy! , service manual says do not do this!
Great video, Ivan! GDI is just a bad idea in consumer every day drivers. I see where Toyota has started running a combination of GDI and port injection. Good idea to wash the valves, but now you have two fuel injector systems, one high pressure and one low pressure being made to play nice together by the ECM. Nothing could go wrong there, right?
Toyota actually began doing that in 2006 in Lexus vehicles
Good Job, oh the pain, weird design for sure.
Very good diag specially when using the scope on the injector thanks for the info
Not sure if they're the same, but I'm pretty sure I saw another video from Customer States What where he did this for an audi/vw and they were Teflon.
The GDI engine with carbon buildup and oil burning, constant engine ping up hills. Hyundai is good for the 5 year 60k bumper to bumper warranty and after that get rid of them. Just my experiences.
17:17 These seals are made of teflon, these type of seals are pain to put on cause you need to stretch the seal and then compressed to the proper size
Those seals seem to be Teflon like the ones used in transmissions. They're the only ones I've ever seen that are "resizeable" but easily cut or damaged. Very similar tools on transmissions, just bigger versions. Typically used used on the stator shafts for pumps or input shafts, etc.
I've only done Honda GDI so far, no fancy tools required except for maybe a puller tool because in GDI they have a tendency to get stuck in the block.... due to carbon or whatever.
Also, in an ATG class with Kris Lewis, found out that carbon build-up isn't directly due to lack of fuel washing it... but it is directly connected to PCV system. I won't go into detail here, so his paid class info isn't given away. Next time I see ya, I'll share.
Hi Cuba! Yup if the intake only had clean fresh air in it, there would be no gunk at all 😁
The carbon comes from the PCV system, but without port injectors the carbon doesn't get cleaned off the valves.
Would a filter/catch can on the PVC system help?
Hi Cuba!
That seal is where I failed on a transmission "repair".....
@@dans_Learning_Curve not much. but if you buy a Toyota, they have a system that has both direct and port injection. Takes care of this problem. And some others. Depending on the situation it could run one system, the other, or even both simultaneously. And it's much quieter at idle
This video turns me against a Hyundai purchase in my future vehicles.
Your sure an early riser Ivan. I’m an evening person, probably from working nights
