Haunted Hyundai...Part 4 - ANOTHER Easter Egg?? (Easter Special) 

It's nice to know Hyundai's engine timing depends on a very small part which frequently breaks.

You have that amazing ability to remain emotionally remote from your work . The best advice that I have ever recieved " never become emotionally involved with inanimate objects "

That's pretty wild! I'd probably just slap in a $.10 dowel pin and hope for the best.

Only you Ivan, only you. Thank you, I was contemplating the purchase of a Sante Fe. Think I will pass for now, you just saved me thousands!

This man is an absolutely amazing and brilliant mechanic....

I'm so impressed you got that camshaft out and removed the sheered pin, really excited to see the next installment 🤗

You win. I have experienced the GDI valves carbon issue on my 2013 Accent with 80,000, severe pinging and oil consumption 1 qt / 500 miles, dealer told me this is 'normal'. Sold it and just using my 2005 Ranger. After this video, I will never buy another Hyundai or another any GDI without multiport. The only smart person(s) in this video are Pine Hollow for their expertise/patience and the first owner who traded the car in.

Unbelievable Ivan! Maybe full time Kia/Hyundai techs know this but who else would?? Your investigative skills are amazing. I understand the process------"what could possibly cause the problem and then go about eliminating them one by one"----however, something like this is so strange that would this even make the list of "possible causes" in the first place. Granted, this problem is kind of related to the twisted cam issue which in its self is strange and almost unheard of. Throw in the fact that you have a lot of pressed on components on that cam and you have a plethora of possibilities to consider. Once again I applaud you for your persistence, patience and expertise. I gotta believe you did not receive financial benefit for this job commensurate with the hours spent. I don't know of any other mechanic that would have done this. I respect many of your peers like Eric O. Super Mario etc. and I am skeptical that they would have taken this situation as far as you did. They would have had to charge about as much as a new engine and when quoted as such most customers would have said no to repair and either let the car go as is or replaced the motor with a used one. You are truly one of a kind, Ivan.

I guess fitting 2 dowels would of made the car unprofitable. 🤔🤭 Excellent diagnosis Ivan. Keep that Kia tech on speed dial.😂

6 years ago I bought a dodge truck with a 12 valve diesel motor. I did research and talked to friends and relatives who had experience with this motor. They said the first thing to do is fix the “killer dowel pin”. Companies even make a kit for this. Peace of mind on my many road trips.

Ivan, your facts and thoughts are high stranded better engineering than the designers of the engine. We love you for being on our side and for all your help The poor owner who paid for for this Van………..! Lucky to have you.

The moral of the story: sometimes there's no substitute for a good visual inspection. Otherwise, you're chasing ghosts on a screen.

You are doing the world such a service by ALWAYS finding the true cause of any problem. Your diagnostic process is stellar because your understanding of the function of the machines and their parts. You, scannerdanner, Eric at SMA, and others help teach and your content will always be out there for generations to learn. Well done Ivan! PS: just dowel it

Hyundai dealer tech: "No, the cam/phaser won't come out without removing the timing cover as there's not enough clearance." Ivan: "Hold my beer..."

Truly unbelievable and unmatched diagnostic and mechanical skills, Ivan.

Ivan, ingenious stuff. You should have far far more RU-vid subscribers, I always spread the word about how good you are whenever I can. Look forward to the final part.

What an amazing series. I can't believe you were able to extract that broken pin so easily. I'm all in on this repair. Can't wait for the finale!

If you look up " NAILED IT" in a dictionary this is the definition- Nick Bee From Part 1 "Bank 2 intake CVVT has either sheared or pushed the locating pin between it and the camshaft. Now the CVVT is slipping on the cam and has bound in an out of time position. This is why when you energize the oil control valve you still get a reaction but base time on that cam is still off. When you pull the valve cover off you will see your timing marks on the CVVTs and crank line up great but the cam is off. Looking forward to part 2!"

Great job Ivan. Always impressed by your ingenuity and never give up attitude.

Crazy diagnosis Ivan! Your obsession with numbers proved out this one. Excellent work. Thanks.

Wow, what an incredible find, Ivan! See if Dorman makes a titanium dowel pin that you can slap in there. Hahaha.

Wow, I look forward to the conclusion video. When you were looking at the illustration of the phaser and the dowel pin, at around 17:00, I could see that you were looking at an illustration of a Dorman part. It was good to hear you say that you had the phaser on order from a dealer. It would have been awful if a Dorman part was the only thing available for a job like this, and then guarantee your work, with all of the labor time involved. I wonder if anyone at Hyundai USA is seeing this series of videos. This failure point is not something they should be proud of, for sure. And unfortunately, even after all of this, the direct injection, without additional port injectors like some other manufacturers use, has left this engine with all of that carbon build-up on the intake valves.

IVAN YOU HAVE OFFICIALLY OUTDONE YOURSELF THIS TIME!!! HOLY FREAKIN MOLY!! YOU ARE A MASTERMIND!!!

EXTRA parts required! Love it. Well played my RU-vid friend.

The reasoning and deduction from the diagnostic supports the shifting of an component and you have narrowed it down . Wow a dowel pin 📍 shear on the cam/phazer wheel, a design feature with all that load on that cam, Nice dowel pin extraction.

Wow. I had the exact same failure on an old Isuzu Rodeo. Cam moved in the sprocket. (No phaser on that one.) Ended up grabbing a cam and buckets out of a Honda Passport at the local LKQ for $30 and sent it on it's way. Thanks!

Oh, my word! That's crazy! I know the dealer we have been taking our Sonata Hybrid to would've never been able to diagnose that much less fix it. They can't even figure out how to diagnose a cylinder 2 misfire. So far, they've replaced the spark plugs, coil, and injector, and we still have a misfire.

Hyundai you need two dowel pins for the load.

Amazing. Technically you weren't wrong about the timing being out. That GDI engine is going to continue to be a money pit

The Hyundai ACME school of engineering.. Nice work Ivan! Very impressive.

I guess you could find a high tensile bolt that has the same diameter and cut off and use the shaft of that....

I was thinking during a previous video about that twisted cam with you and Eric O. Go figure Hyundai a sheared dowel pin!! WOW Amazing videos can't wait for the conclusion.

What a nightmare! Great reasoning in face of an almost unreal problem!! Great job taking the bolt out, removing the camshaft and removing the broken pin. This is like a suspense thriller 🙂

You are a genius. One of the best mechanics I have ever seen/known. That is why they pay you the big bucks. You deserve it. Looking forward to the next episode. No thanks to Korean cars. Toyota only for me. My 2006 Corolla over 220,000 KM is still going strong. Knock on wood. Just regular maintenance.

Nicely done Ivan. Had a similar issue on a 2012 Range Rover Evoque in the phaser. These parts required fixes aren’t always fun.

Yes, Ivan - you ARE the Magic Man.

I was a little worried when you tried pulling the dowel out while it was still hot and expanded. I thought you were going to cool it down first. But it worked great! Very cool 👍😎👍

Unbelievable! I'm so glad I don't have a Hyundai. Seems like a royal PITA. Great work and perseverance, Ivan!

Ivan really fantastic how you worked the problem out. Mega impressive.

And all this time I thought Fords we're the worst cars on the road. Great series to watch, your train of thought is fascinating.

Man Ivan, there is only 1 guy out of 100 that would do it this way.

This is turning out to be an epic case study! Good job Ivan.👍

That engine was not designed to be easily repaired. I'll never buy a Hyundai. You were terrific in determining that problem! Your customer found a great technician.

Excellent bit of diagnosis. More cliffhangers than the best drama.

oh the twists. its as if the knife edge wasnt enough !!!!

Really Ivan 4parts? Ok man. I’ve not sat and watched a movie or gone to the movies because I can’t sit through it (gets distracting) but I have zero issues watching a 4 part series on ur adventures

Whew! When I saw you attempt to weld on the broken dowel on the cam shaft with a mig welder, I cringed. I don’t think I would have attempted that without a tig welder. Hats off to you and your steady hand you got it! Great video series so far! Going to watch the next video in the series right away for a happy ending.

That's freaking amazing!!! Ivan for the win!!!!

Damn ! Love the determination ! Problem , How do you Even Bill for a Job that just ain't quite in the service manual ? Love how the Dowel just Popped out ! If it were me , No way that was going to happen ! Can't wait for the Final ! Thanks for Sharing

The Ivan giggles; for a viewer of his channel it brings a smile and joy, for the car owner, not so much. Always such a total root cause analysis, most experienced techs would have tossed in teh towel, never Ivan.

I like how you make it easy to follow what’s going on! After eliminating one thing after another, it became very clear that something had to have moved! Thanks for being so thorough in your diagnosis as always! I wish all mechanics were like this! Thanks!

This is better than any Easter egg hunt I've ever been involved in!!!!!

What A Nightmare , No Turning Back Now Ivan`s Tools + Knowledge = Winning Combo 👍

What a nightmare to work on. But you are doing a good job. Too bad they aren't like boat propellers that have shear pins that can break, and are easy to replace on the propeller shaft.

Ivan. I got home and was thrilled to watch this video. What a great diagnosis about the Phaser and pin. Well thought out and to dig and have confirmation from the Hyundai tech would have been sweet confirmation. Very proud of you. Cannot wait for the next video. Thanks for everything! Cheers

You never cease to amaze me Ivan, LOL great video

That was incredible. Who would have thought this was the problem. Thank goodness the owner came to you, but damn that is still a big bill. You saved that man a load of money. If he went to anyone else would they have found out the problem on the first shot? Not at all. Another car I won't buy.

What an amazing result! Good job persevering to get the camshaft out without disassembly of the timing cover/chain etc.

At the start of this video series, I was questioning how a chain could jump that much and not be very noisy. Great job bringing us along!

I think the take away is to avoid Hyundai. Odd design issues and serious repair challenges has me extremely skeptical about this brand.

Ivan, you are a genius, you have the patience of Jobe, and your arsenal of tools (and I'm talking skills) is outstanding! In one of the comments in a previous video someone mentioned the dowel pin. So here we are. I'm sure at this point you are grateful for the support you've received from friends. Looking forward to conclusion. Also wondering if you'll ever let another Hyundai into your shop. Thanks for Sharing!

Good job Ivan, My question is if that dang dowel pin is that critical then why did Hyundai make it out of shit steel? I would have made that sucker out of the strongest metal on the planet, and put two in that camshaft one across from the other that would transfer some of the torque and stress to both pins, not just one weak pin. Ivan, I am loving this series, good luck brother. :)

That's why Toyota has dual injectors on their GDI engines. They still put injectors portside also, so that they help keep the valves clean.

Ivan Holy s… (crap). I mean talk about digging. Damn, you never give up. Way to go Ivan! Some people would say if there is a will there is a way. You just proved that.

Brilliant diagnosis! So much knowledge. Thanks for sharing Ivan

Why are you comparing intake 2 to exhaust 1 5:00 mark? Shouldn't you compare intake 2 to intake 1?

Super impressive! Doing the impossible that the service centre can't do....

Wow! I would have expected the dowel to be hardened and less likely to shear. Great diagnosis! I've never had an issue as strange as this. Well, I did find an auger engine carb missing a drilled passage - but that wasn't nearly as technical or complicated as this. Strange things do happen, and you have to keep an open mind.

Ivan, you are a genius!

Movie Review: I loved the scene where the dowel pin came out!

The way the valves carbon up on these modern direct injection engines is a disgrace

Whoa, that was nail biting scene too see too get that camshaft out lol. Good call on that busted dowel! Wow, broken! Nice to have Keith in speed dial and have hyundai guy call ya, lol. That was like surgery precision with those hands and boroscope !! Haha. That's how detailed view i could give! Nice that owner is understanding of what is going on. Most don't! You're the man! Excellent video!! Many many thumbs up!!

Not sure if that dowel pin is really supposed to be under load, may just be meant for alignment, with the torque between the phaser and cam taking most of the stress. If the HPFP previously failed, maybe it jammed and put too much load on the cam and caused it to shear the dowel pin and shift the camshaft? Sort of like the Woodruff key on a lawnmower blade heheh.

Ivan, this is why i watch your channel and people bring their cars to you. A lesser mechanic might have done the timing chain and then sent the customer to the dealership. You'll figure this one out.

This is such an epic series. Can't wait for the conclusion.

WOW IVAN ,great workmanship.1st you ran into the issue that you thought {correctly }that the cams were off somehow.OK FINE 2nd And much harder was you figured it's NOT caused by slop in the chains.Then you probably said "WHAT THE HECK?"And this video was the most important one.!!! YOU figure out the phaser and the relucter cam DON'T LINE UP RIGHT.After looking at the print you spot the DOWEL PIN !!!!BINGO ANT THEN you manage to Pray to the gods to ALLOW you to get the cam out without disemboweling the motor.haha And the you get the dowel pin out. ALL THIS when the dealership would have SWORN IN COURT

Great work I wonder how many other models have this fault he said 4 cylinder are worse 🤔,keep up the great content 👌

thats an amazing find . also a tap on the choulder for the owner off the car , for doing the right thing .

This is one of those "can of worms" that I'd be too nervous to open. Your confidence is unmatched!

Ivan, you are a very clever and resourceful man.

Epic case study!

Just recently diagnosed the same issue on a Kia Sedona Bank specific misfires along with trim issues and found dowel broken and shifted in the phaser. Stinking high pressure pump must really load that cam. Weak spot , ya the dumb dowel I was able to reuse cam and new phaser installed Perfect

Hi Ivan, Boy, that was luck getting that pin out of the camshaft. I applaud your tenacity to solve an unusual problem and save the customer money. Stay safe.

Unreal. Well done Ivan!

GDI cars should do what Toyota has done and have fuel injected into the intake manifold during certain engine loads on some of their GDI engines. It adds complication but is worth it to keep the intake valves clean on GDI engines. For example the Toyota GT Yaris 300HP 3 cylinder, amazing car.

Running thoughts: This pin should have enough strength to hold the normal torque forever. A normal torque can not be that high, otherwise there would have to be huge thermal power dissipation, in 10's kW range and that would not be possible to cool off. The only thing that may shear such thing (or a key, used sometimes to hold the torque between shaft and a wheel) off is the cam shaft becoming jammed somehow. But then I would expect some severe damage on some other part of the shaft, at least some impact marks. Plus why would such fault be so common on this type of engine (or its 4-cylinder cousin)? The only other possibilities for such huge forces without anything actually colliding is a torsion vibration resonance building up huge amplitudes. These used to happen on fixed timing engines, but here the VVT phaser and its oil fill should act as a damper, safely dissipating the vibration and so preventing large amplitude from building up. Maybe when there was low oil pressure in the system. And that could be then the link towards the bad solenoid valve: Nonworking solenoid valve caused the phaser to operate without sufficient oil pressure, even on its end-of-travel stop limit, so with hard, undamped resonance oscillations may have developed at some critical rpm, overloading and so shearing off the pin. The vibrations may have come from the high pressure fuel pump (therefore it affects just the cam shaft driving the pump), or from the chain links going across the sprocket teeth (we are talking about kHz frequencies, essentially the frequency of the "cling" when you hit the part with something). But all that is really strange.

Rainman Ray, and others I'm sure, have a procedure to clean the intake valves. Feeding in the cleaner into the air intake. It does work if done properly; see the videos. Holy mackerel, if it isn't one thing it's another with this project. Great video, I hope it all works out well.

you are the man. amazing diagnosis

Well done :-D That position pin came out so nicely, perhaps the heat from welding a handle on helped. i was happy it didn't become a nightmare. i thought i was being silly by thinking about marking the chain. I was still mentally running away lol.

I swear I read in one of the previous videos leading up to this one, someone said this was the problem. Crazy diagnostic ivan, keep up the good work. Looking forward to more series.

This is just crazy. So impressed with the depth and detail you go to proving this issue. 👍

Hadn't realized that GM had trained Hyundai's engineers. It explains a lot of the problems you found.

Hyundai tech: no shortcuts on pulling the phaser ... Ivan: hold my lemon squash baby ... :-)

Hi Ivan. I have to admire your perseverance . Very interesting process to get to the culprit. I ran into a similar situation with my old VW Rabbit the half moon dowel on the injector pump ( Diesel) had moved 2 mm twisted over in the spline . It drove me nuts for a day to get the timing right. 👍💥

Man that was awesome watching that dowel pin come right out with the pliers. Nice work!

In Europe, the Nissan X-trail with the 2.2 Diesel engine has on the exhaust side cam the vacuum pump chain driving sprocket. From that sprocket, the camshaft ps get it's signal. The sprocket is positioned with a 3mm pin. Over time it brakes, the symptoms are that the engine starts for about 1 second, then shuts off. Good thin is that the engine timing would not go off, like on that hyunday, may cause valve and piston kiss in extreme case. Temp fix is to disconnect the cam sensor and put in limp mode to get you home. Usually a needle bearing needle is cut to length, or a good quality drill shank.

Ivan you can use quality drills and taps….. it’s cleaner than Welding and they make cobalt and carbide drills and special taps for extraction in hardened materials!)👍😸

i have been working for hyundai for 6 years and never seen that , but we have slightly different engines here in the ASDM and the V6 engine is MPI not GDI but the 2.4 theata 2 engines are GDI and never had any issues , i have had a stuck exhaust cam phaser on a IX35 a few years ago and the cam bolts are only torqued to 70 NM which didnt seem much but it is the spec

Weld the dam think to the camshaft including fitting a new dowl pin and you will never have that problem again. Sorted.😉👍👍. That's definitely a job you never want to do twice.

I said it in the last episode...cut your losses. Next problem is a valve job...at least they need cleaning at the very least. I wonder if Hyundai should do what Toyota does...dual injection. Ivan...great save on the camshaft. That was real real slick. Some may argue with me....BUT I have seen enough, heard enough and have personal experience with Hyundai and I think they are not as good as Toyota or Honda. Since the hi pressure pump is driven by that camshaft, the lock pin should be made larger or have 2 of them to be safe. Clearly that one Lone pin is over loaded.
