Very cool way to check for play... such an obvious way to check for freeplay, but there's NO WAY that I would have thought of that myself. Thankfully we all learn from people who are willing to share... you learned it from someone and I now learned it from you! Awesome!

[@SuperMarioDiagnostics]

Well said! 😃 just passing it along 😉 thanks Thomas!

[@ranchorelaxo2287]

And here we stand on the shoulders of giants....

[@dddandruff]

How did you fix the problem homie?!?!?!?

[@arthurfricchione8119]

Mario, I admire your honesty and also all the tips you give to us DIYers. I find there is usually no set approach to finding odd engine noises. You showed us something that can be very useful to us in the future. Thanks much for the heads up. 👍👍👍

[@CarsExposed]

Oh man old school wins 😁... I’ll definitely remember that test, great job bud 👍

[@SuperMarioDiagnostics]

Always great to have ya Igor! 👍cheers!

[@scdevon]

@@SuperMarioDiagnostics This is a great preliminary test for the bottom end. You can detect excessive piston-to-wall slop, wrist pin looseness and even some rod bearings that are getting loose. You can't argue with movement and noise on a solid steel ratchet extension like that !! Great tip !

[@edward8435]

Just came across this video. KZbin "pushed" it out to me. I've worked on my own cars off and on since high school, so I definitely like to learn and KZbin is a great resource now-a-days. Good stuff! 👍🏼

[@worsttintentions]

Thats an awesome test. I've been slid by one of these dfi Hyundais. I had the same noise from the chain and found guide particulates in vvt solenoids. I did chains and guides. And low and behold it was bearing failure on cylinder 2. No codes no misfires.

[@themechanic6117]

Solid diag, no harm done. You did what you had to do to find the problem 👍

[@VoltageDropDiagnostics]

Mario, that was a simple and brilliant check! Ive never thought about checking them this way.

[@SuperMarioDiagnostics]

Thanks for watching sir!

[@mliesemeyer]

Legit video man. I don't usually comment on YT but you explained everything so well. You're a talented dude. Keep on it.

[@SuperMarioDiagnostics]

Thanks Andrew!

[@danielnmaryannyoder]

Thank you for sharing this clever trick. I just got done taking the oil pan off to check for a sloppy rod bearing, only to find out that I can't even see the crankshaft. Now I'm ready to remove the spark plugs.!😊

Great job man, love that old school stuff!

[@allanandrowey5219]

Absolutely right. If someone is giving me advice, especially one as cool as this, I'm all ears 😀 thanks for watching!

[@miguelparedes1888]

Thanks Mario for the video , definitely informative, educational, I sure as heck would not have thought of that test but thank you for sharing .

[@alexmessina3383]

Nice. Certainly didn't sound like a big end but you couldn't have ruled out a wrist pin. Always satisfying when you nail the issue, you shouldn't be kicking yourself on this. Great job.

[@powayimports4175]

Really cool way of checking. Will remember it for sure! Thanks!

[@Gmansour1971]

You sir are a diagnostic beast. Great video dude.

[@krisjohnson7810]

Won't see that on an A.S.E. test! Great video.

[@ponys191]

Thank you for sharing this very useful trick tip. This would have saved me a bunch of time from figuring out a similar issue I had with my buddies 2013 GMC Terrain 2.4L. I ended up removing valve cover to inspect top end first, no issues found. Removed timing cover next only to find no issues with timing components. I Removed oil pan last and found a ton of metal debris in the bottom of the pan which looked to be bearing material. After inspecting all Connecting rods I Found Cylinder #4 had excessive play at the wrist pin. I was able to stick my camera inside to physically see the issue as I moved the connecting rod front to back.

[@ahmedabdelsalam850]

So all that knocking was coming from the bottom oil pan because i have the same knocking problem and i dont know what it is exactly other than knocking sensor 😂

[@Sal-rh6mk]

awesome video. i learn alot watching your channel. am glad u share your tips nd tricks. i wish my coworkers were more humble like your coworker. so i wouldnt struggle as much. thanks man

Yeeeeeees! Thanks a lot! You saved me much time for searching. You're great man!

[@gargoylebrother]

WOW I totally forgot this tip for checking connecting rod bearings. I have never used it but I have heard of tech's doing it. thanks a ton for the reminder will definitely add it back to my list of tests. Ohh I almost forgot that test also works well on wrist pins to check for play there at well. That maybe why the sound is coming more from the top end and why is sounds different from a end rob bearing too.

[@Jpilgrim30]

I remember that Decourcey seminar. He was a very talented tech. I believe that car had a slightly bent rod from being hydrolocked and the piston was slightly below the deck compared to the others. That’s the crazy things you run across as a diag guy and is the reason you have to think outside the box occasionally. Thankfully we have things like the WPS500X to help nail it down.

[@flatratemaster]

We stock the OEM filter for those, and have several come in the with a noise that the filter change did "fix" it, but many have not luckily for most of those cars were still under powertrain warranty and got engines replaced at the dealer

[@SuperMarioDiagnostics]

Thanks for watching Mike 👍

[@jakeandrus690]

Nice find man! Got fooled the same way on an 09 Honda civic, swore it must have been top end but had one worn out con rod bearing. Mine had glitter in the oil to seal the deal. Lesson learned!

This is a trick my co-worker taught me, but i do appreciate the remark. Thanks for watching buddy!

[@MidwayAutomotiveInc]

awesome job! We had an equinox in the shop with a strange knocking noise. We finally took it apart & found the piston wrist pin bushing completely gone on one cylinder & the other 3 cracking. Would have been nice to confirm with this simple test before taking it all apart. Spec for clearance is only .0002" this one had about 1/8" of play. Thanks for the videos & sharing your experiences!

[@ponys191]

I just ran into a similar issue with a 2013 GMC Terrain 2.4L eco tec. After removing oil pan I had found cylinder #4 wrist pin had failed causing a huge amount of play and the knock the customer was hearing. I found this video after my Diagnosis and went ahead and tried this trick and it worked. Would have saved me a lot of time from removing the valve cover, timing chain cover and lastly oil pan.

[@wyattoneable]

Nice editing Mario. The picture in picture was cool. That was a great tip using the extension bar. The car doesn't seem to have that many miles on either. Too bad for the owner. The ending was classic for a shop.

[@SuperMarioDiagnostics]

Thanks Wyatt, i figured i should throw some editing in there lol. Well they owner traded it in to the Hyundai dealer, so sucks for them 😆 i could NOT delete the ending :) thanks for watching Wyatt!

WOW that's very cool . As for the aftermarket filters causing knocks - yes Ford had the same issue and buddy would see the oil filters and deny warranty. Seems in Fords case some were knocking because media from the filters were plugging the oil feed.

Nice mario i know this is a 2 year old video, but it just so happen that it was on the first feed on my screen hahha, i will definitely try that test, but i work at hyundai mostly its always the bottom end, when i hear that kind of noise i will always call the shortblock because im just depending on my stethoscope. But atleast you showed a different kind of testing to rule out the bottom end. Thanks again

[@justinhayward5027]

Good diag man! Keep it up

[@SuperMarioDiagnostics]

Thanks Justin!

[@robinsonsauto]

Great tip and trick 👍💪 most likely a rod bearing or maybe wrist pin. Great job as always

Hey thanks Will! Yeah i was thinking that too. it didn't go away when disabling each cylinder, but that's because three of them were bad 🤣. Glad to have you here buddy!

[@johnfranklin5277]

Just curious, how many miles, and how often oil was changed, my new car has a 1.6 l turbo...and were you able to get it repaired?

[@andrewk778]

Follow up comment. This video got me thinking. I cannot remember seeing that procedure before. How else does someone check lower end bearing clearances without dropping the pan? This was simple and effective. Well done.

[@SuperMarioDiagnostics]

Piston height across all tdc's, maybe with a dial indicator. One could technically look at an in cylinder waveform and see that everything is perfect except for peak compression. Don't know any other way other than oil pressure being affected, and the traditional noise associated with this problem. 😆

[@sinegra30]

Amazing way to check for piston rods play! I thought it was going to be a intake cam phaser oil pressure CVVT valve related problem...

[@SuperMarioDiagnostics]

Thanks!

[@exmotorsports]

Yes, the great Dave DeCourcey. It was like loosing a library of knowledge. We are so lucky to have some of his seminars recorded. Sometimes using old school techniques is a win. 🤣 Hearing that air hammer reminded me of a SD classroom video he did. To funny. But hey, Britney still came in strong.! 💪😆 Cheers Brotha

Sorry Mario I hit the wrong button last comment. 🤨. But that was awesome with the find. It's hard to find older techs that want to share their tips and tricks or the trade. Great guy for that and who knows maybe he could start showing us tips and tricks as well on his or ur channel. 😁. Take care brother

[@SuperMarioDiagnostics]

Haha that would be awesome. Thanks for watching buddy

[@justinporter6701]

One trick that is extremely efficient and effective for con rod issue is killing spark on that cylinder. The noise will get SIGNIFICANTLY quieter on the affected cylinder when spark (or fuel) is killed. This not only confirms con rod issues but also isolates the cylinder with the issue. Just another method to know.

[@SuperMarioDiagnostics]

Yes i mentioned that in this video, only problem was that since multiple cylinders had this issue, deactivating cylinders one at a time still left me with the noise 👍 thanks bud!

[@W.Khairi]

Well done, That was quite a sound, Wonder what caused it...I always thought gamma engines were reliable engines...maybe it is turbo or GDI related.

Hi !! from Puerto Rico had the same problem with my 2013 Veloster turbo stock with no alteration with only 63,000 miles only. Waranty deneid the repair. When I open for my surprise it had bent a rod.

[@claudenobles779]

great creative diagnostic...so how did you solve it?

[@sonofmontezuma3732]

Back in the day we did that on Babbitt bearing engines If we had play we cut some leather ,stick it in crank worked the crank back and fourth till it would turn and off she went for another year or so Team work great thing No team work =no money for all involed Hyuandia always hv oil pressure issues remember the santa fe Love the ending 👌

[@diydrivenGA]

alot of us owners have grouped together on a few FB pages for the 1.6t (Gamma engine) and have found that while everyone recommends 5k intervals, 3-3.5k is best....I have sent oil out for analysis and both times the oil has been good and in spec, but the flashpoint was noticiably lower....also while 5w30 is recommended, some owners in hotter climate or who push the car have started using 5W40.....another car , the 1.5t Honda civic, is also having fuel dilution issues arising from the turdo direct injection, blowby and short trips in colder climates. Honda has addressed the issue with a ecu update and upping the weight of oil on the affected cars to 5w40.....translation: treat these types of engines old school - use great oil/oem filter and warm it up before heading out......also check your local dealer if you don't do your own oil changes....you'd be surprised how many use the wrong weight, semi-synth, or conventional then blame the owner/manufacturer after 70k miles.....and keep your receipts...Good Work Mario!

At the dealer they have special tester for that. It screws into the spark plug hole, has a dial indicator on top and an air fitting, it actually has little holes in it that push air in or suck vacuum out of the cylinder so the test is done at TDC and it pushes and sucks the piston and the dial indicator measures the play. It would be a lot easier to explain with a picture but the fitting has the air holes and the extension rod from the dial indicator runs through the center of it.

[@SuperMarioDiagnostics]

Yes I've seen it. Anything over .050" fails lol. That's a lot of play in my opinion.

[@ablackformula]

Does anyone have a link to this tool? Trying to do the same test on a 4 cylinder where the plugs don't go straight up and down.. they're on an angle on the front of the head. It's dang near impossible to push straight down on the top of the piston.

[@CoolAirVw]

[@SuperMarioDiagnostics]

[@RJMaker]

Nice job, I say life is full a little tip's and tricks, and this one was a good one. I can't imagine why anyone would have a serous problem with this method. The only thing I could think of is creating superficial scratches on the plug threads and the top of the piston. Out side of that, what possible real damage could be caused? Certainly the piston, pin , ect is far stronger then the force required to push the piston down with your hand right? Maybe carbon ?

[@PaulyD0859]

I’m catching up on your vids, so I’m a little late commenting. It’s hard to tell from the video but it doesn’t sound like bearing noise. Although it does sound like a top end noise, not so much like a valve lash noise either. After your buddy old schooled you, I have to agree with Will Robinson, that it’s most likely a wrist pin noise. You hear it at the tops of the cylinders. Kind of a piston slap sound. Anyway, good job on the diag. Too bad the fix was declined. Those are the ones you take apart to learn from. You file away the sound in your memory so you know it next time. 👍

[@SuperMarioDiagnostics]

I sadly have this issue and trying to figure out the best course of action. Love the car but I may either replace or rebuild the motor. I was considering just replacing the conrod bearings but meh.

[@xThrasherrr]

I'll have to give this a shot. I have a 2013 Base Automatic. I changed the oil on it 2yrs ago and went with a Wix filter. I noticed it started making that knocking noise at idle and its very noticeable. However, sometimes it doesnt knock. Next oil change I put an OEM filter on it, same thing. I've installed a Catch Can inline woth the PCV valve. I've taken it to Hyundai and they charged me $120 to "diagnose" the noise as normal engine operation, which is BS. I even pointed it out to the service manager out in the parking lot before I gave them my keys. I've looked into recalls on my car to see if I could get it fixed, nothing comes up. I even mentioned to the dealer that I heard there were TSBs out there and people were getting whole new engines put in for this issue. They had no idea what I was talking about. I know my way around vehicles but something about working on these cars scares me a little haha! Glad I saw this vid, I'll give it a shot.

[@brendanlee8419]

But there was a recall on the 2013 1.6 base model made in south Korea that they announced mid 2019. And only for that model/year causing premature ignition.. I gotta take mine in soon.

I have an veloster turbo 2014, it makes a noise similar to a growl when it is stationary or when you press the pedal to accelerate and the revolutions are decreasing. Sometimes I hear it and sometimes I don't. Any suggestions or ideas of what might be causing it? Pos The car runs excellent in all senses.
