Just so you know Ray: some times it does not matter how boring the things you do in the video are, we just enjoy sharing your brain space and being in a similar state of mind. For some of us, that is apparently enough to make our day. (And it may just as well be less boring than some of the things we ourselves have to do in the course of our workday.) 😁😁😄😄

Hey Ray. At first I thought you were just another joe working on cars. However, after consistent uploads and seeing day in and day out your work, although I may not agree with every little thing, anyone who does this day after day after day and pays attention to detail and focus will become a master of their work. Good job!

I'm amazed that you can take so much apart, and it all gets put back in place with no parts/bolts/nuts left over. And it eventually starts. Good job !!!

This dude is blessed with socket gravity, I swear every time I drop something it’s unreachable without having to remove something that’s completely unrelated to the job.

Having a cup of coffee and watching Ray video is all you need. Keep up the great videos Ray.

Ray, I am not a mechanic but I love watching mechanic work. All the things I do not get to do. Watching you go through your day doing the same thing over and over is relaxing to me. No need to appologize. We come because you are good, You do not explain for 20 min and then show 5 min of mechanic work. we enjoy watching "boring" things as they are new to us. You are soothing to watch and a highlight of my day. And anyone who gets bored watching you I pity them. We come to watch you work and to listen to you as you work. To enjoy your work as you do enjoy it. You are not boring .. EVER.

This engine is a real treat lots of extra maintenance to prevent this stuff. Have one with 100,000 miles on it. I have to check the oil every 2,000 miles. Run a can of CRC intake valve and turbo cleaner every 10 to 12,000 miles in it. And then also Chevron Techron fuel injector cleaner every so often. It's been trouble free but lots of extra maintenance.

I believe you’re one of the most devoted KZfaqrs I’ve seen. I know making and editing videos to upload daily isn’t a simple task. God bless Bro

As an aspiring mechanic that feels like he found his perfect job type I can ensure you that this is not boring at all. I have seen a lot of your videos now and I'm ahead in class and I feel like I can thank you for a big part of that. Than you for your videos!

yo at like 9:15 that's the whole reason why i love your videos man. I'm just a mobile shade tree "mechanic" (glorified parts changer with basic diag), but the uncut just "it is what it is" instead of these youtubers glorifying wrenching making it look like a lego set. Your videos with explanations of systems and specific things on certain vehicles, procedures etc etc ... love it man keep doing you!

Hey Ray, I’m a retired maintenance engineer and do not find your videos boring. I watch your channel and other technical ones in my quest to learn something new every day. I applaud your work ethic and appreciate your sharing of knowledge. You certainly contribute to my quest. Thank you.

In the UK I get them as I get home after all day as A BMW Master tech. You are a really clever and conscience worker Ray. I wish I had your positivity👍

having a daughter with a Kia I can tell you for sure it was not acting like the recall engine, she went through that early before they admitted the engine had problems. That was an adventure. Great diagnosis and repair.

29:00 Ray you forgot the hose clamp in the right upper corner. On the small diameter hose 🤓. Great job anyway 👍🏻

I have a 2012 Hyundai Azera with 89k miles on it. Still runs, looks and sounds like a champ. Love my car.

I know that everybody complains about Sonata and there are many issues - but I think that most of them are manufacture-related (that instance they assembled engines without cleaning them properly etc.) than of the design itself. Mine, a 2011, has over 125,000 miles (first 25K were done as a rental) and it runs great - kept cleaning the valves with GDI, doing proper maintenance in time, install a catch-can. Was checking the clip because next year I want to cleanup the carbon buildup (CRC GDI cleaner can only do so much) and it is a great tutorial what is to be done.

Superb editing, correlation of video to music was spot on. Direct injection is such a gimmick; engineer a system that works great, until it eventually kills itself by it's nature.

This is the perfect job for a magnetic socket set. 😉 You found the spring clamp on the PCV, but forgot the one on the crankcase vent hose (at the airbox end of the intake tube @26:27).

I own a Hyundai Santa Fe, 231000 miles, and have had no problems with it except, plugs, coils, fuel level sender, fuel pump later, brakes all the way around and back,alternader , and until I learned from you an emission code, I then took your advice and quit over the filling tank, and nada light. Thanks again Ray for an entertaining informative video, looking forward to more.

a pleasure to see an honest mechanic

Always NOT boring! Great job. It still amazes me how some cars use a plastic intake manifold?!

Ray it would interesting to see what failed actually inside the intake.Could dissect the old one or is it in the trash already?

👏👏👏👏👏for a great video. Your videos are never boring. You’re talking about those engines failing. Our daughter- in-law had a 2011 Hyundai, she was driving down the Interstate heard a boom, thrown rod through the side of the block, she got a new engine under warranty

If we had more thorough and honest mechanics like you there would be no concern if the customer is being scammed or taken advantage of.

I noticed one vacuum hose clamp that still isn't replaced at 29:03 towards the top near the large air intake, hopefully Ray saw it prior to attaching engine cover.

Love the total change before/after with some relatively straight-forward fixes. I don't know what you were using in that drill but you can stack about 20 zip ties, bind them in a couple places with tiny ties and then cut off the square ends. Put the square end of the stack in the drill and it works well dislodging carbon. Oh... and as other have said holy moly that sheer thickness of the hand java on that steering wheel!😀

My daughter had a similar problem with her 2015 sonata. It was repaired as a recall.

The best method I've seen so far for cleaning the intake and valve is dry ice blasting. Too bad is not cost effective for even a shop to have the equipment. The problem is that dry ice is expensive and it will melt in a short amount of time.

Ray is still touching that steering wheel with his largest organ of the body in unprotected mode.

The incrustations come from the exhaust gas recirculation. Some repair shops use shredded walnut shells to clean the intake ducts. All VW vehicles (VW, Audi, etc) suffer extremely from coked up intake ducts.

I watch all his videos! I just got through building a rat bike . And watching this channel. I am retired. And enjoy watching a man work. I never been afraid of work. I can lay down beside work and go to sleep.

So the intake/plenum was replaced to avoid cleaning it? It's common knowledge that the intake valve carbon build-up is because the vast majority of engines now utilize direct fuel injection, which means to make the engine last, never use dinosaur oil or synthetic blends, only use full synthetic oil. I just cleaned out the intake chambers on an Impala 3.6 which had quite a crusty coating on the valve stems. A relative was told his injectors needed replacing at $800 so he bought a new set on Amazon for $116 and after a year of trying to avoid the inevitable and running on only 5 cylinders, my wife asked me to help her bro. Cylinder #1 had a chunk of carbon lodged on the spark plug electrode and then a compression test revealed both #1 and #3 had weak compression. Further investigation revealed the thick carbon build-up and finally a cylinder leak-down test revealed the intake valves were leaking. Yep pressurizing the cylinder through the spark plug hole while a capful of Berryman’s B-12 sits on the intake valves will provide a good visual of the leakage. Like you, I cleaned the closed ports, scrubbing with a variety of wire brushes and sometimes a thin-bladed screwdriver to scrape off the baked-on hard chunks. I modified a wet/dry vac so a small modified PEX pipe (bench grinder thinned walls) would fit the ports to suck out the debris, used in conjunction with an air hose to help dislodge the particulate and make it airborne. The bonus was the PEX was able to fit inside the spark plug ports to vacuum the top of the pistons in case anything made it there. After cleaning everything, I started taking a closer look at the leaking valve faces and seats. I advised having a machine shop do a valve job but since that was out of the question. I briefly considered valve lapping but ended up just doing what I could without removing the heads. Anyway more scrubbing and sort of washing with Berryman's B-12, reduced the leakage enough to raise the compression enough to actually make combustion possible so again I had to use the vac along with an air hose to ensure nothing remained in the cylinders, reassembled everything, and started it up. Then I raised the RPM while spraying various carb cleaners into a port that was downstream from the throttle body. The idle fluctuated with an occasional miss on cylinder #1 and cylinder #3 but was smooth on the freeway while trying to blow out the remaining carbon. I pulled the plugs and they were completely black again so I had to repeat the cleaning process many times. After making sure everything was blown out, I took everything apart again to install the new fuel injectors, new spark plugs, and new intake/plenum gasket. The engine purred after that but after my brother-in-law put a couple hundred miles on it, the car died on the highway. I soon found the reason for a rattling noise in the exhaust that went away after starting, which my B.I.L said began after he got into an accident years ago...much of the contents of one of the 3 catalytic converters totally obstructed the final catalytic converter. The front catalytic converter appeared fine but the middle one near the firewall had a honeycomb-like structure that looked stained and maybe slightly clogged but blowing air on it made the chunks drop so I cleared it out. The other cats passed the blowing air test so I reassembled by making the 3 gaskets using a sheet of exhaust gasket material, which was less than $20 compared to the 2 @ $20 each and the rear @ $8. I thought for sure the oxygen sensor would set a code but it hasn't. I'm shocked that it's running so smoothly. BTW I also installed an oil catch can on the rear PCV in case a moron changes the oil with dinosaur oil again. I hate working on vehicles that use dinosaur oil. That crap seems to bake on everything inside the engine. And it's foolish to ignore an engine miss...those catalytic converters aren't cheap.

If that was my personal vehicle, I likely would have tried the seafoam sucked through a large vacuum line first. Let it sit for an hour and then drove it. Not necessarily a long term fix, but obviously the system is flawed because it should never get that plugged up to begin with.

I was afraid to acknowledge the fact that I get up at 5AM to see what Rainman is up to, however it seems that I'm not alone. Yes I start the kettle add sweet tea and sit back search for Rainman and look mechanical. Good work Ray, we've done it again another satisfied client. Click!

love watching it go back together, but I always have that little bit of anxiety thinking that I missed something

I completely removed that system and epoxy'd the shaft holes on the ends. That was 5 years ago and the car still runs great.

Be prepared for a lot of Nancy's today and lots of REEE's, Ray. Good ol Monday mornings. Great job as always. I look forward to your great content and appreciate what you do!

Great video, I did notice there was one more clamp that didn't get put back on at the end. Other than that great work.

Ray I can almost guarantee that it did not need that knock sensor replaced. I work for Hyundai and the vehicle needs to have a rod bearing clearance test and if it passed that it will receive a software update and if it comes back a second time and passes the test again it will receive a knock sensor. But usually it ends up needing a long block with the p1326 code.

I am surprised that a 5 year old engine needs such work, including the replacement of the manifold. After watching you and Wes and Eric O, I wonder what vehicles have the least high maintenance requirements. Thus far, my 08 E150 Ford van and my 15 Jeep Renegade have not required much work except for a fried starter on the Jeep 3 years back. I enjoy all your videos. Be safe.

That thing is filthy!! I have one of these in 2018 with 95,000 miles and it still looks new - inside and out. I have been on the lookout for carbon buildup, but I've devised a 'self cleaning' kit I want to install. Gonna get before/after pix. Gonna be interesting, I think.

That's the most discusting steering wheel i have ever seen, thanks for the great content Ray

Waking up to Ray and his wisdoms coupled with his Rayisms is the best way to start my day. Coffee rounds it out. Wait what Ray reeeed himself a first to be sure.

Ray & all- Look on Amaz, get "Rare Earth magnets 8x3mm button." Superglue or epoxy one in bottom of each 3/8" or 1/4" drive sockets you frequently use for smaller fasteners (

It would be interesting to disassemble the old intake manifold to see what the fault was.

That job is easier if you remove the cooling fan. But you did a great job.

my step mom had this exact same car with the exact same motor and exact same issue. we had ordered a part to repair the issue, but the engine siezed up before the part arrived haha. we dropped a new long block into it from a junkyard and sold it to the local used car dealer.

So glad went so well at 9:45 you had wires holding intake on didn't see on reinstall. Happy you got those connected might have had to edit out those bad words that come finding you can`t plug those in when intake is installed. Had things like that happen not good , not good at all lots of bad, bad words . Great Video

Ray, have you ever considered using walnut shell blasting with a vacuum hose attached for medium removal like they use on Toyotas and Mercedes Benz vehicles?. Worth looking into it. Cheers You channel is AWESOME!

That steering wheel is nasty. The only way i’d touch that thing is with 10 ply latex gloves.

Hi, Ray. Great vid. GDI engines have issues with carbon buildup. Valve stems aren’t bathed in fuel, and the intake manifold can be gunked up with carbon. I got a multi-port, 4.6, 2012, Hyundai, with 64,000 miles. Runs like new.

I bet there was a knock sensor range performance DTC. That will set the flashing check engine light and the misfire codes. replacing the intake and vcm is only going to prolong the inevitable. there is a software update that goes along with the knock sensor, but odds are its going to need an engine sooner than later because the rod bearings are smoked. just some friendly advice.

This channel helps me to learn about all the cars to avoid.

Haven’t tried it myself yet, but Charles over from Humble Mechanic, I believe, tied a bunch of tie-wraps together and used the tips as a sort of brush to clean the intake valves of a caked up engine, I’m interested to see how that works and if it helps to cut time on these kinds of jobs.

On the intake runner control if the electric solenoid coil functions and the vacuum valve receives and sends vacuum where it supposed to, i found that using an intake valve cleaner sprayed into a vacuum hose Upstream of the intake manifold per the cleaners instruction can free up the butterfly. I am in Phoenix and the plastic was not warped rather it had carbon on it. I used CRC intake valve cleaner for GDI engines and saved the $500 part and the additional $500 of labor and it has worked for eight months now.

Nothing quite like the satisfaction when you step on the accelerator and find that it actually goes. Score one for the good guys.

I remember the 2017 Sonata. It's the one with schmoo all over the steering wheel. Ugh!😳 Ray should have been wearing gloves.

Ray, excellent work as always. Was wondering if you could take apart the old runner to let us see how much junk was built up in it. Would an engine cleaning additive have helped prevent the build up? Or maybe one added to the gas?

I had to do some repairs, back in the old days, for some HP printers, and they had several coarse thread screws designed for fastening into plastic. I developed a hatred for such designs (screws directly into plastic) because of this. I do not envy that you have so many in this repair.

Sometime I wish I had a nice little shop to work on my car when it decided to create drama, seeing you work makes me a bit jealous as you have both the knowledge and the right tools for the work! (Most of the time) Love your videos!

VW has been fighting this battle since the 00's 🤣 Actually got a Golf in the shop at the moment, misfire at idle, pulled the manifold to find similar amount carbon build up and thought it was an acceptable level (they can get extremely bad) Might have a go at cleaning it up to see what happens. But I work for a bunch of fools who have zero mechanical knowledge and can't even order parts... I feel sorry for the customer.

That steering wheel is a hazardous waste site! It looks like years of not cleaning sunscreen off the wheel. BTW, a neighbor just had their car that was just like this stolen. Cops said this brand is an easy target.

Was I the only one yelling "Ray the starter...." No? I'm glad he took the time to clean the carbon deposits (I have to do it in my 220K mile Sonata). I wish he would have checked operation of the pcv valve, it's a cheap part that usually needs to be replaced.

I have a 2015 Kia Rio 1.6 GDI and use a can of CRC intake valve and turbo cleaner every 2nd oil change and it cleans things nicely. It also works great when cleaning any direct injection intake valves that get that carboned up.

I already knew the intake manifold was going to be nasty inside. The steering wheel is nasty, so if they can't keep that clean, why would I expect that the owner would bother to do other maintenance items.

Surely this is really poor of Hyundai? I'm in new Zealand, but can imagine that would be a $2000 or so repair here? I'd be pretty pissed if my 2017 car with 100,000kms on it needed this work!!

Ray on these cars Hyundai actually has a tsb/recall on the VCM and the Knock Sensor. Went through this with the wife’s 17 as well. When the VCM dies it automatically throws it into limp mode. It was a LONG 45 mile drive to the dealer.

This is a byproduct of direct injection and crank ventilation system, with a port fluel injected system gasoline passes over the intake valves washing the oil remnant into the cylinders, but di does not and clearly soot accumulates in the intake ports, valves and eventually builds up on the seats, this why some manufactures retain some kind of port fuel injection (along with better low rpm idle) with a primary di fuel delivery system.

Nice work as usual. I would suggest you may want some KOKEN "grip" sockets that will hold a nut or bolt without worrying about it falling off . (I liked them so much I got 2 sets, one for shop & one for traveling). MRSUBARU1387 has short picture videos for a better description.

Asking the experts here. On the Hyundai direct injection engines, how does someone prevent this issue?

Amazing. Imagine in 1960 buying a new car and being told "yea in 5 years you will need to remove and replace...." anything other than tires!

The CRC intake valve cleaner is fantastic. Flood the ports. Let it sit for 30-60min. The carob melts off or is brushed off. I love this cleaner.

My Mom has a 2014 Kia Sorento with that same GDI engine….. those engines are trash. This carbon “issue” is a severe design flaw in my opinion. I’ve done the carbon cleaning procedure with that stuff from CRC twice and sure, it restores SOME power and a little throttle response but it barely makes a dent in that carbon build up on the intake and valves. The ultimate “fix” (temporarily) is to walnut blast the valves (search KZfaq), that stuff is like epoxy on those valves. Once you walnut blast the valves and get them all clean you’re good… for another 50,000 miles, then you’re back here. What a mess 🤬

How on earth do you remember where all the parts go. When you rebuild what you have removed. Bloody amazing.

I use a little bit of paper in the socket to hold the fasteners while I start them. Or byutle

Thank you very very much to all automotive engineers out there, 'cause every mechanic enjoys going through all that plumbing and connector stuff just to get a car with an attitude afterwards. You guys really make our freaking days shinier.

The way most shops clean the carbon on the valves is walnut shell blasting. It gets them pretty clean. And install a catch can between the pcv valve to keep the valves clean longer.

this was very good, thanks Rainman. Crazy big piece of plastic to replace. wish this was 4k is it me or are we seeing a lot of Kias and Hyundais here? most of Ray's customers are not wealthy people and I hope they appreciate a mechanic who will deal with them honestly.

My 2010 mini had the same carbon build up, the dealer used a media blaster/suction machine to get it nice and shiny

Electronic intake runners are a pain But hey they give us more work to feed our family's right @Rainman Ray's Repairs

I am shocked Ray did not hose that steering wheel with brake clean.

People dropping off a car with no fuel is arguably the most annoying thing they do.

Looks like job for Seafoam. I've used a couple of bottles on a used N54 BMW (DI twin turbo) that I bought and it completely cleaned up all carbon from the intake valves, so I now use it every 15,000 miles on all my vehicles to keep them clean and running well - without ever touching my socket set. I Can't recommend this product enough.

Slightly off subject, but I thought I'd mention that with many engines now using direct injection rather than port injection, intake valves and ports tend to get grubby more quickly and the various injector cleaners in the fuel or added by the customer do nothing for those items in direct injection engines. I recently saw a short ad for a new gadget that allows on-the-vehicle bead blasting of the valve and port that would make that nasty job much easier and cleaner. I know you love those spray cans of solvent, but as that kind of work becomes more common you might want to ask your tool supplier about this.

this video is not linked to part 1 description thanks for the upload

I believe the knock sensor is a recall or reprogram

Me and my kids were walking around the store yesterday the next thing I out of my mouth was due to do both of my kids looked at me like oh that's just is very smart mechanic that I watch all the time and that's what the shop phone does when it rings

I got really sick starting over the weekend. I have not been able to get up and leave the house for three days now. These videos have been helping get through. Thanks Ray, I am right next to you holding the light poorly.

I believe the engineering term you're looking for on those inserts are called compression limiters

i like this guy a good sense of humor and a great work ethics ring ring.

Im changing the intake on my 2016 tomorrow. This video was helpful.

Hyundai/kia is covering the 2.4l engines past the the warranty. I've had customers with 175k+ miles have their engines replaced under warranty. Any time one of those engines come in for performance issues I contact the dealer before I ever put a wrench to them.

No quick fix but you brought the madness back to life.....

Wish you were my mechanic, love your work 😍👍

Makes me appreciate mechanics more having seen this video, I wouldn't have a clue about putting all the wires back together.

Ray, the 2017 Hyundai Sonata 2.4 was part of a class action, the original (first) owners were given a lifetime warranty on the engine because of the GDI carbon build up!

I found myself channeling Ray last night when I realized my delicious adult carbonated beverage was empty, "ANOTHER"

one little part that causes so much hard aches. Have a great day to you too!

I always find it amazing that Ray can tell what size the bolts are just be looking at them ..

The Master schools the teachers, again. No engine change. Just a shit ton of hard work.
