- Diagnosing a Bad Head Gasket: How to Spot the Telltale Signs.
If you suspect your car may have a bad head gasket, it's important to diagnose the blown head gasket before it causes more serious damage to your engine. In this video, I'll show you how to spot the telltale signs of a failing head gasket, including low engine compression, overheating, coolant loss, and more. I will also show you the different things a head gasket seals. In addition to that I will also show you why a bad head gasket has the symptoms that it has. Finally, I'll walk you through the basic diagnostic process, so you can determine if in fact, you do have a blown head gasket or not.

I have a 2010 Toyota Yaris 1.5 engine, my question is I have overheating problems, and bubbling when cold through the radiator cap opening, but I do not have milky oil, nor white smoke out the exhaust pipe,so based on just the bubbling on a cold start, what part of the head gasket do I have the problem with that is causing the overheating? my cylinder compression test is #1 190 lbs #2 189 lbs #3 190 lbs # 4 220 lbs as we speak.
What will take to get my truck on the road what can I put to fix my blows head gasket
I need to know what product I can use to take care of the problem so I use
Fantastic video. Thank you for sharing your expertise with us. I have just replaced the radiator in my Camry. There was no coolant left in the reservoir and I had to add two liters in the engine. I caught it just in time. Yours is the best video ever. Regards from Sydney Australia.
*so i am on my third blown head gasket and this is within two months since the last fix and i babied the car(never pushed it or went over 120kph(80mph) with the car so what might be the reason it continuously blows as this is verrry frustrating right now*
I'm a little over middle age and can't believe how someone so young, can be so articulate. Your knowledge and delivery on problems are so professional. You really are a breath of fresh air on UA-cam.
Cheers Steve.
Honestly, I almost skipped the video when I saw a young guy and a Honda. Glad I didn't. I'm impressed. I seldom subscribe to anything. This guy gets one.
It's called having a passion
@@SummerEazelivin Having passion does not mean one can magically speak well.
Totally concur!

Unbelievable how easy it is to understand the diagnosis of whatever the problem may be going on. So glad I came across this.
That was the most informative upper cylinder diagnosis Ive ever seen.
Thanks! That was the idea. So many people make videos saying coolant is mixing with the oil, so the head gasket is bad. Nobody ever explains why.
@@RepairGeekwould you happen to know how deep are the cooling jackets? Also, can a coolant leak from the head gasket cause the engine to get hot?
I was literally about to say exactly that. I know stuff but the details n this video I've never actually heard anyone say before. I actually learned something 2day 🤔. SUBSCRIBED.
Great teaching @repairgeek. Very clear explanation and good video... I'm saving it in my playlist for sharing lol
Good technician who methodically covers the range of scenarios involved with head gasket issues.
Rule of thumb is, the longer you wait to fix a problem the worse it gets. So you should stop immediately upon discovering a problem with your car. It can mean the difference between replacing the gasket or replacing the vehicle altogether. Excellent video.
or trying different things to sort the problem until you eventually and very expensively replace the whole vehicle ....these issues never givingly present themselves
@@vincemarshall8550why are you guys replacing a vehicle because the engines bad? Just drop a new motor in lol
@@TM-fx5le not a nice job in a transit mate but i get your point
This comment is underrated
Don’t all these problems practically make the car totaled in terms of cost to repair. Requiring extensive labor. Like what’s the average cost to replace a head gasket with labor. $5k+… especially today’s rates. What’s the cost for a used engine + labor…
I have watched dozens of videos about blown head gasket related and, by far, this is the best ever I watched. Congratulations.
Sir, I have watched so many videos trying to get a full understanding of how to diagnose a problem with my combustion. This was by far the most thorough and succinct I’ve found. Thank you thank you.
Man o man if you are not a professor I don't know what you are!!!!! Explanation on point. I'm a rookie lube tech on my way to wrenching, and this was absolutely gold. Thank you.
Tremendous tutorial ! The amount of information , and specificity , and video shots , and simple to understand terminology ; has , without any doubt , whatsoever , made the greatest impact on my learning this particular topic . Thanks mate !! 👊🏼
Excellent teaching! Thank you for being so detailed and covering the essentials in terms a novice could understand. Keep videos like this coming. Thank you!
Excellent, thorough description. I really appreciated the distinction made between the higher pressure oil passage ways, but the fact that the coolant system stays under pressure (albeit lower) after the motor is shut off. Great points, and helpful in diagnosing different symptoms. I've done motor swaps and head gasket replacements on several motors and still learned something. Well done.
Beautiful and coherent articulation of what the head gasket's role is, and moreover, why you are leaving your engine to certain demise if not repaired in a timely manner.
By far the best video on UA-cam about this topic! congrats!
I am much less car stupid now .
No need to ask questions because you answered them before I had the chance. Great video man for real...much thanks
Gone through many related content but this was the best, answered almost every question in mind!❤
Such a great educational video, deserves more views.
Great video! Thank you for breaking things down, and explaining things.
Thanks I think this video was on point and it explained all the symptoms' and diagnoses. I live in the Bahamas and is very much appreciative of all the equipment you use to diagnose this problem. I will continue to follow you for more mechanical videos .. Again Thanks
Easily one of the best explanations on the types and causes of various head gasket failure modes. Excellent approach using the removed head for the explanation.
Thank you so much! You are an awesome instructor/teacher!!!! Even I halfway I understood how it all is working together as a wh.❤
I'm not sure how much practice you do, but it's working. Kudos 👍
You are a star. This information helped me a lot.
I wish I had more free time in my life to watch all your videos
Amazing f**** video. Best, most detailed informational video I’ve yet to see online on this topic. Covered all the basis and made it easy to understand. Really needed the help figuring out my 636 leaky gasket issue & this def did it for me. Excellent job, much appreciated.
Great explanation!!! Thanks for making video.
Outstanding and informative overview of the whole diagnostic!! Smart guy. Very smart indeed
Of all the videos I've watched on head gasket failure, this video does great job of explaining this problem. Thanks for this great video
This has been incredibly informative to me my head gasket just blew and this video helped me diagnose what exactly happened
Excellent indepth analysis. This video couldnt be better. Thanks for sharing
Very methodically detailed video on this topic. My tacoma has bubbles in the radiator.
I drove a Nissan with a bad head gasket for 2 months and 300 miles , I just kept extra coolant and oil in my truck to top it off, but it got annoying and after 2 months I was able to save some money to put as down payment on a newer , better car, drive safe and God bless ❤
2 months of driving with a bad head gasket will damage your engine badly enough that you shouldn't feel okay with selling it, except to a dealer or scrap yard.
It's quite simple for a mechanic to change the gasket, if you find yourself in this situation and can't afford the repair you should probably consider selling it there and then. The mechanic, or some car enthusiast can repair the engine and you can use the funds to buy a cheaper car.
It's a tough call to make since we're usually reliant on our cars to get to work, but the car's worth a lot more money with a working engine that has a bad gasket than it is once the engine itself is damaged.
The gaskets themselves are usually $100 or less, it's the labour to install them which is expensive. Compared to a new engine which may cost thousands, and has an even higher labour cost you're really incentivised to act quickly once you discover a bad gasket.
excellent explanation . The one thing i do is pressurize the cylinder with air and watch the cooling system for bubbles , like you said but without running the engine. Ive used this technique several times on Hondas and it worked for me
Very intelligent dude and great at explaining things. Videos are very informative. Thanks
Very Nice! Your delivery on this topic was top knotch and right On Point! Keep those videos a coming. I am sharing this... Thank you...
Great explanation mine I did it 3 times and I finally found it it was a cracked head deep in the oil gally so I got a new head and problem solved...the main problem was oil in the coolant like you said the oil has more pressure then the coolant so it was blowing into the coolant. I had no coolant in the oil.
THE BEST EVER COMPLETE BREAK DOWN!!! Thank you!
Excellent explained
Very detailed explanation! Probably the best video I’ve found. Subscribed.
absolutely the g.o.a.t explanation about blown head gaskets.
Great video! This has always been a fear of mine.... I have an 04 Accord. I know this day is coming. Thanks for doing a great video.
Hands down the best vid ive seen on head gasket issue explanation.Thank u very much for taking the time to make this.
Bro well explained I appreciate it and so many ways you don't even know thank you for being so thorough and explaining everything to a "T" 💪😎👍
Smart young man
This was the best “Explanation Video” I’ve watched
Great info. Thanks buddy.
You are an awesome teacher! Thank you for this video.
Dude this is the best breakdown and Informative video I’ve ever seen on UA-cam. Amazing job and I learned Alot! Thank you!
I just subscribed, Thanks for sharing this information. I have bad head gasket on my s10 . You helped to confirm that.👍
Great explanation. 👏
From an engine reconditioners view those alloy blocks with the open style water jackets around the cyls are a poor design and will always have headgasket problems the tops of the blocks go all over the place with constant heating and cooling. When you run the miller over them they have low spots everywhere.
Yeah initially I thought my car had a Leaking radiator but the bubbling radiator (radiator cap removed and engine on idle) combined with misfire in cylinder 1 in the cold morning confirmed what the issue was. Thanks for the details 😊.
This was a first class tutorial. Excellent!
Amazing video. Thanks for saving me so much headache and money on diagnosis
Man,how did you get so smart at such a young age? How old are you? I just found your channel and you do such a great job of explaining and showing things. I'm subscribing.
I'm older than most realize. I'm 35.

Explained very well. Great detail!
Great Video! Thank you for posting this!
Great video. You got a new subscriber pal 👍🏾👍🏾👍🏾
Appreciate your knowledge and clarity. Thank you
Excellent video. Thank you for helping me better understand this issue. 🙏🏼
Awesome tutorial, another one I learned over the years is after the engine reaches operating temperature, one shouldn't have water dripping out the exhaust , that is a sign of coolant leaking at the head.
This guy is very professional and well trained
Great explanation
thank you . Sir, very informative,
well done very Educational. cant wait for your next video
I’ve been looking at hella head gasket vids this guy explained it best
That's a perfect explanation, thank you very much
Hi all. Thank you for the lesson. All the best for All of you.
Best class on blown head gaskets
Wow!!! This is awesome!!! Not sure I’m ready to be a mechanic. Yeah but I can now ask some questions!!!
I live in Stark County and work in Cuyahoga Falls. I also have a 2001 mustang gt in mineral gray. I really liked your series on the mustang and getting it ready for your trip.
Hopefully we cross paths once the weather breaks and can swap mustang stories 👍
Excellent demonstration
I have low compression on side by side cylinders. But not exchange of coolant and oil in engine or radiator. Car is basically running on two cylinders out of 4. Before it gets worse I'm gonna put it in the shop and replace the head gasket. Hopefully it's the only issue. Thanks for your vlog.
Great video breakdown bro
This seriously the best video on diagnosing!
Very well explained and videod, self explained diagnosis.
awesome video, thanks for sharing what you know
Superb video!!!
Perfectly explained, thanks
Excellent information shared thank you brother
great video taught me a few things. thanks!
Great educational explanation
Best video I've watched on UA-cam? Just might be. I wish America valued education. You should be educating our children
Excellent content. Thank you.
Fantastic Video.. Great explanation. Glad i found your video. if there is a leak between coolant to oil NOT (ENGINE combustion gas to coolant) then are you saying that tool used to chekc exhaust gas in ccoolant will not work ?..
Great Explanation ,, now i know what is a gasket and what are the issue associated.
Very good video in detail !!!
Very well articulated
An amazing video - liked and subscriber 💯
Loody brilliant very informative 👍👍👍
Learned so much thank you
You are very informative!
Great job on the walkthrough!
Awesome stuff! Thank you!
Very informative and useful❤
Excellent video thanks. There's another possible scenario which wouldn't happen on your Honda but it seems to be happening on a friend's M-B with the OM601 2 litre diesel. Oil is coming out the exhaust, without affecting the coolant. I haven't actually got the head off yet but there's a place on the head gasket which could lead directly from the oil supply to the cylinder. Symptoms are white smoke, rough idling and eventually oil spray from the exhaust.
