- Don’t get fooled on the idea that head gasket sealers work. THEY DON’T. Especially long term. If they did, car manufactures would sell the product for their vehicles. They don’t.

Mechanics hate liquid gasket sealers because they lose those blown head gasket jobs
Nope, I wait until they come back for engine and heater core replacement.
@@Motorcarnut no you don't. People who couldn't afford it the first time aren't gonna be able to afford it the second time.
That’s partially true. But I do get a decent amount of gooey blown head gaskets where that crap is everywhere where the coolant goes that has to be flushed and several times.
@@Motorcarnut what is your recommendation to flushing it out?
Never had a problem with the one I use k-seal, worked every time never had a problem of any kind.
I used some 6 years ago and still going strong. Sure it can fail at anytime but so can the gasket. Im happy
Good for you, probably wasn’t a head gasket problem in the first place.
@@Motorcarnutand you know how?
@@Motorcarnut or perhaps it was a head gasket problem?? We don't know unless we inspect the vehicle. There have been many experiences, depending on the severity of the problem, that this temporary fix has worked for years.
Which brand did you use?
What kind of head gasket seal do you use
Mechanic here, it works.
Good to hear that for you. I don't do temporary repairs. I take care of my customers so they always come back and recommend theirs family and freinds as well as my internet family!!!
Which one works best?
@@Chosenone429You'll want to make sure your head and block are still in a serviceable condition. Clean everything properly so there is no oil or debris on anything. I use Spanjaard copper gasket spray, it's a great product.
@@Motorcarnut you sure can and that will be 2000+ dollars, CHA CHING!
That’s like neglecting your body and complaining about the doctor bill.
i went to three mechanics that said the car wasn't fixable. I was prepared to junk it so i threw in a bottle, if i can get a few more months out of it while waiting for a new car because wait times for new cars are insane right now i'm happy. It was 30 bucks and so far so good. I wouldn't trust it going any long distance but for my work commute it works for now.
Hey, as long as you’re aware it can fail at any time and you got a plan, go for it
Which one did you use?
Well if you guys didn't charge 2 grand to replace it maybe we wouldn't need to use the sealers. Huh?
Or if you didn’t neglect your vehicle you wouldn’t have to worry about anything!
@@MotorcarnutI didn’t neglect mine and it still blew…
@bake2299 Sorry to hear that.
There are many many instances where this sealer actually works. I have seen it with my own eyes.
Every situation is different. And it depends on how severe the problem is. If you have a vehicle that is 20+ years old and is worth around $1500 or less with a blown head gasket, or warped head, is it worth spending $3-5K to have the head milled down? If the vehicle is on its last leg, this temporary fix will at least give you time to shop for another vehicle.... unless you have emotional ties to a piece of junk and want to invest time and money in something that isn't worth it. Otherwise, if the vehicle is relatively new and worth more than it costs to repair it, then YES by all means have the head milled and a new gasket installed.
The problem with that is I get so many of people with inexpensive cars that tried that crap already and now have bigger and more expensive problems because of it.
I say it depend on the value of the car. If your a guy in highschool how bought a beatup car for $1500 bucks its not worth the $3500 to $5500 dollar job that will take a month in the shop. It will not be the same and there is no guaranteets will not have the same or another major issue. If for example its a classic car your late grandfather loved and left you it might be worth it. In the event you have no way to pay that much or its way over the cars value why not try a sealer if its going to be scrapped anyway. They might be a temporary solution. In that case start saving and trade it in or sell parts on on ebay when it dies.
Fair enough statement
I had a head gasket blow on a Lexus. It was Winter and I attempted to use gasket liquids. I used the silver colored head gasket sealer, I will not mention the name. It was brand name. Seems to work for maybe a couple of months maybe less. I started losing antifreeze again so I removed all of the liquid water antifreeze along with the head gasket liquid as much as I could and then cleaned with tap water and then drained the tap water. Upon refilling I use distilled water and antifreeze recommended for Lexus. Then I used the copper-colored head gasket sealer. Again brand name. The copper seem to work a little longer possibly three-and-a-half to four months. All the chemical bottles I use said it was a permanent fix. That was not the case. I checked all the usual things like cracks in the radiator which there was none. Radiator hose leaks thermostat hose or thermostat housing leaks which there were none. So the engine got to where it finally wouldn't run much at all because of the water leaking into some of the cylinders. In my case it was cylinder 2 and 4 bank 2. A leak down test proved that it also had a leak on Bank 2. It was very slight but it was only cylinder three. The leak down test proved that was a gasket. It took four months for me to tear the head off due to work hours. I'm not a full-time mechanic but an engineer for an unrelated job. After removing the heads and inspecting the gaskets they were an off brand of Fel-Pro. I did not install these. they were installed by the previous owner. The gasket was called PrimeTorque. Which was an odd name. After some research I found out they were made by Fel-Pro. The car was a 2008 and I can't say exactly when the head gaskets replaced - however I believe it to be a absolutely shity job. I found bolts loose all over the place while taking the engine apart. However all of the main head bolts were extremely tight and I believe they were torqued to spec, but that was about the only ones. After removing the head gaskets, an inspection prove that the Silvery colored gasket sealer, had created some clogging areas specifically near the top of the cylinder. They were small amounts of silver caked around the top of the cylinder head. Some of the small passages were filled with the gray material. The gray material was definitely the head gasket sealer liquid however it was not hardened but it was soft and easy to remove with one finger. In my case I do not believe the silver material had completely clogged all of the passages. What I did find is that the silver material had hardened on small parts of the gasket however did not completely make a seal. I did not find traces of the copper material anywhere - except in the antifreeze. I could not find evidence that the copper material had hardened anywhere on the gasket. The break, in my case was between cylinder 2 and 4 mostly. That's where the head gasket was the worst. I could not find any evidence where the chemical had hardened like glass, as the bottle stated that it would. Anyway I'm replacing it with a new gasket and doing it the right way. That would be mostly by the book. I still haven't decided if I'm going to use the copper head gasket spray along with the multi-layer gasket that I purchased.
Thank you for sharing your experience with these head gasket sealers. They are a bandaid nothing more. I see it all the time in the shop, what could of been just a normal head gasket replacement ends up be other problems caused by the sealers like clogged heater core with on most vehicles cost more than the initial head gasket replacement. Also clogged radiators and water passages etc. I understand people’s frustration and desperation so I try to make videos on head gasket replacement so if the want to tackle the job themselves they can.
Thermalweld was the best decision I ever made for my 2001 Cadillac Seville with the notorious 4.6 Northstar. Sure, I could have got Northstar Performance head studs and bulletproof kit, but that'd be $1000+ in parts and $6000+ in labor. Thermalweld was $250 and after listening to Robert explain how it works and what makes it the real deal, I decided to trust him. It was either that for $250 or get rid of the car which I couldn't bring myself to do. My car wouldn't even start because of how much coolant had entered the combustion chambers. 11k miles later and still running like brand new. Definitely recommend.
The way it clogged the leak it will clog everything else soon and then the engine would have to be replaced. But I understand the cost comes into play, thats why these products sell. Just like those products that are supposed to make a certain part of the anatomy larger and there are testimonies all over the internet about that. But I hope your repair lasts for you. Good luck!
@Motorcarnut what makes it completely different from literally the usual $20 fix-it in a bottle is that it bonds only to what the seals were made of, using ceramic and some other material. It only clogs it up if the chemicals are mixed in with coolant before setting. If done correctly, it will not clog up anything. I have done this with other engines and have torn them down part by part. There was never any clogging in those engines.
I was losing a gallon of coolant a week. I use one bottle of sealer. 20,000 miles later, still holding.
@@renegarcia5284 did you use Thermalweld or some other common solution in a bottle?
Were you the same guy on reddit with the blown headgasket Seville lol
We appreciate the video and effort also for not trying to be against sealers I can see you prefer the official repair but cars don’t last long you fix one thing then next thing you know it’s totaled so non mechanics prefer temporary fix
That’s totally understandable as long as you know it’s a temporary fix at best.
First, I appreciate you sharing your experience. I am listening. I am currently using K-seal to help stop the coolant loss in my newly-built engine. I am yet to know the result. The K-seal instruction says it would take up to 10 days for minor coolant leaks. I am not "desperate", but in fact, I am trying it in the last resort because 3 separate highly-rated mechanics have diagnosed my engine with flying colours. The engine has been re-built. No evidence of coolant leakages, all engine components and hoses are dry as a desert, no evidence of mis-firing, no evidence of pressure losses of both the cooling system and the cylinders, the engine is very strong and revs like heaven, but I have to top up the 250ml of coolant for every 200 km of travel. It is a frustration to a point we all stood there scratching our heads and looking at each other. Take my words, I am more sceptical than you for this kind of cheap fix but as I said, it is the last resort without another options. If you have any suggestion, I am happy to try.
Why would you use that crap in a freshly rebuilt engine??? Obviously something is wrong. That crap is only going make things worse. It’s either burning it or leaking somewhere. How does the exhaust smell? Does it smell sweet? Take out the spark plugs and see if there is any coolant residue on the plugs or in the cylinders. I had engines with slight coolant leaks and never misfired. How’s the oil level? Make sure it doesn’t increase. They have test strips to check for combustion gases in the coolant. Could be leaking or burning coolant at a certain temperature very slightly.
@@Motorcarnut
I am yet to find out if it is crap or not. The reason I use it because it will be my last resort prior to pull out the engine again for detail assessment. As said, 3 mechanics had diagnosed, the spark plugs were good. The block tester fluid was good, the "extra high" pressure tests were going. Everything was good but I have to top up coolant. Of-course something is wrong but what is?
Then they are not mechanics. I’m not the there to diagnose it. It’s not that difficult if you are knowledgeable. Put it this way did the engine have this problem before you rebuilt it?
@@Motorcarnut
No, the engine didn't have this problem before rebuilding it. The problem is they can't find the cause. All the possible tasks you suggested were already carried out. What would you do next? Also, the engine oil has been checked to be clean (they drained it out). Engine oil doesn't increase over time.
@@Motorcarnut I’m in the want boat, brother in law car overheated twice and got valve job done new valve guided valve seals everytbjng fresh new oem head gasket and same issue no issue of leak or overheating yet but I check the coolant every other day and I have to keep putting some , so it’s burning it but not noticeable with the cylinder head leak detector it comes out fine even the pressure test is fine , only thing I can think of on my end is cracked block possiblt
1100 bars leak fixed my blown head gasket on my 96 honda vtec..white smoke coming from a tail pipe, coolant mixing with engine oil its all goned..it works!
It’s a bandaid nothing more. You think it fixed it by clogging the leak temporarily and also little by little clogging your radiator and everything else until the whole engine has to be replaced instead of just the head gasket. Go ahead and take the car on a long road trip through Death Valley with the ac on let’s see how good it works. Nothing replaces a mechanical repair. I’ve been fixing vehicles for 40 plus years and seen all that crap come and go.
But don’t worry if the engine gets destroyed, they have a warranty on the bottle to cover the cost of the bottle you paid for. If that’s not a clue I don’t know what is. Lol
@@Motorcarnut ur absolutly right! i used it only temporarily i bought it for 1k here in philippines its equivalent to 10US dollars..i changed my engine last october coz of other issue but until now there is still a fiber on my reservoir nd radiator..ty, stay safe
I tried it on a K16 K series and it worked perfectly, i will eventually get around to doing a proper seal but for now it is what it is gotta make do with what i can
I hear you! Good luck!
What your saying is exactly correct . Everyone thinks the special liquid will fix anything ! Like Magic !
That's the point, just because it clogs something doesn't mean it's fixed.I just give people the facts, let them decide for themselves.
I currently have the head off of our 1989 Honda Civic DX 1.5 engine with 146,000 original miles. I spent some 8 hours removing remnants of original gasket material and other crud from the mating areas of the barrels and outer machined areas (upper-top surfaces of the block). The head is at a machinist shop to examine head, valve seats, install 16 new valve seals and shave the head flat. I bought a spray can of Permatex Copper Spray-A-Gasket high-temp sealant. Your message is to not use any of such products, but only the gasket with no sealing aid. Please comment.
What are you going to use that spray on? Not on the head gasket? You never use any gasket makers on head gaskets. That spray is not a head gasket sealer it’s a gasket maker two different things.
These are the sort of things you would use on an old beater that isn't worth much, to kick the can down the road a few months to a year. They work, just not in the long term and usually cause more issues later like clogged heater cores, radiators and thermostats. It'll work in a pinch to buy you a little bit of time but don't put this stuff in a vehicle you really care about or plan to keep without wanting to put an engine in it. Because this shit is hard to flush out. Case in point, I had an 89 dodge dynasty with a 3.3l v6. Car was worth maybe $350 and smoked white from the day I got it, threw some bars leak in there and drove it to work pretty much everyday, a short commute, and got about 6 months out of it before it started smoking and overheating again. Used that time to save up for another car. After that it went to the scrapyard as it wasn't worth saving. Situations like this sure, otherwise give these products a wide berth as you're just kicking the can down the road with more headaches, and expenses, at the end.
This is a fair assessment of these products, well done.
@@Motorcarnutso you just admitted it works? If I product could seal it for a year it theoretically could seal it for much longer as well
@adam_bh Don’t take my comment out of context, read the comment I was responding to. If you don’t care about your vehicle or to fix it the right way and or don’t have the money to fix it properly then what do you have to lose. If that’s sounds good to you, go for it.
yeah the correct way to do it, do you offer financing for a 5k job? if you want cash up front or the persons just needs their car to make it 2 more years it could work.
Hector Experience--My experience, they work for some blown head gaskets, even if the head has warped. Sodium Silicate is very nasty stuff and can definitely seize your engine if it is mixed with the engine oil so: NEVER use sealants if there is coolant in your oil, this means the head gasket blew all the way through coolant and oil passages. This is definitely a head gasket replacement issue. Now, if you only have combustion gases in your cooling system or white smoke out of your exhaust, this means the gasket issue is only present from the combustion chamber to the coolant passage. For this you can try a sealant. I have used it in 2 different engines with this problem, one has been running for almost 3 years now (head warped about 0.15mm) the other one was done a few months back and is working fine. Obviously both vehicles were pretty old and a head gasket change would have cost more than the value of the car itself. A head gasket change IS the permanent fix if your vehicle is worth it.
Good comment, I’ll let people decide for themselves. Got a lot of information for people to read.
Exactly.... I used BD (following the directions exactly) on a 97 Aerostar not worth repairing, loosing coolant in exhaust... I have been driving it maybe 3 times a month locally for the last 7 years now.
how do you clean/flush the coolant system after using one of those sealers? what do you recommend to get that junk out?
It's pretty difficult to remover it all especially if it clogged up somewhere in the system. Take out the thermostat and disconnect the heater hoses and back flush the system with a garden hose. Try it from all ports in all directions. But if it already caused damage it may be too late.
Just follow the directions on the product label. I successfully used Blue Devil on two different vehicles with marvelous success but, ya gotta follow the directions to the letter.
Depends on the sealer, with the silica types it's good ideal to do so cuz they tend to clog up other things.
Replacing the head gasket or engine is not economically viable on really old cars especially where you suspect there are other lurking expensive issues. The only economically viable choices are throwing away the car for scrap or gambling $50 on a bottle and then scrapping it if it fails. Replacing the head gasket or the engine is a hard no.
That’s too broad of a statement. It depends on a lot of variables, such as what type of car, condition, mileage, whether you can fix it yourself and so on. Being a payment junkie or worse, leasing a vehicle to me is a waste of money especially with this economy ahead of us. If you have a rusted banged up economy car and you’re having a mechanic fix it then it’s probably not a good idea but if it’s a low mileage vehicle in really good shape other then the head gasket problem and you’re fixing it yourself, why not?
Also if you live in a remote country and shipping brand new head gasket from overseas costs an annual salary
Wow, that’s true
I used a head sealer Blue devil on my skid steer diesel in 2005 it was a cracked head can you believe it still is holding as of today, Steel block , steel head. You could see the crack in the head when I did it and actually watched the sealer fill up the crack like melting glass But would I use it on a steel block to aluminum heads NO even if it fixed it its just temporary and you have all that crap in the engine blocking up other area's
I added Blue Devil to my coolant and it worked for about 4 days. After that, I added another sealer which promised money back if it didn't work and it absolutely did not work. To get my refund I require a written statement from the mechanic stating it didn't seal. The worse part is that I began to see fiberglass popping up out of my coolant once the coolant was low. This is a huge hazard for humans as you know so out of my experience I suggest never using any of that stuff since you're likely not sealing it for good and you're putting yourself in harms way by inhaling the fiberglass material.
Yep, they will give your money for the product but what about more engine damage and time and labor?
If the head/heads are warped I wouldn’t expect any sealant to work.
Warping is caused by the engine overheating. If you keep track of your temp gauge you can greatly reduce the possibility of overheating the engine. Gaskets which brake , tear or damaged can be patched with sealant.
My situation was combustion gasses getting into the coolant which over pressurized the system causing coolant to blow thru the reservoir cap and rain coolant under the bottom of the car when pressure built up.
Key word is “patched”
The Bars Leak with ground copped in it worked for me.
Hopefully you won’t destroy the other perfectly fine coolant system parts.
I’m just trying to use this stuff to get more miles on it before putting a new transmission and engine in
I can't recommend any sealer but they're are people who says it works so it's best to use you own judgement.
If its already mixing coolant with oil it wont work. If its just smoking and putting excess pressures it sure will work.
Opinions vary
I have a 02 bravada definitely has a blown head gasket.Paid 1400 for it.A ur again has earned it's money back.Not worth fixing?Or is it?160.000 on her.Im leading towards yanking engine for parts and scrapping I have a s10 with 4.3 vortex also and other parts are interchangable.scrap or no?
Hard to say. I think that's a personal choice. The engines are not interchangeable, one is a 4.2 and the other 4.3
@@Motorcarnut glad I brought this up.ty
I’m confused what does he mean “how is it going to seal in between everything” if the oil and/or coolant getting in between them passages and you add sealant in then the sealant will get in them same passages then correct? I’m not the best at cars and stuff but I’m I thinking about this wrong? And even if they aren’t the best to use wouldn’t it be worth trying if you’re just going to replace the head gasket if it doesn’t work then could a sealant do irreversible damage to where it couldn’t be fixed?
Can clog the heater core and everything else it decides to clog and if it doesn’t work you’ll end up paying more than a head gasket.
Thanks for your video will it seal external coolant leak from head gasket
I have no idea as I do not recommend any sealers. However, there are some people that said it worked for them, so do some research and decide for yourself. Good luck
CHANGE YOUR GASKET...MAN! FUCJK
THERE are no products in the world that repair your gasket,,
so it will not last, its just money to the pit... and other problems in your engine
Do mechnics put this porduct in the clients car engine?? thye dont give you any guarantee cause they know it doesnt work that way!
100% accurate!
I’m 15 trying to replace 04 4.7 Durango mls head gasket. Is any paste or glue required or is it just put in dry?
No, never put anything on the head gasket unless manufacturer for your particular model states it. And that’s a pretty big job for a 15 year old? Bravo!, you remind me of when I was your age.
Dry
I'm Goin to try this sealer tomorrow
If it work’s temporary and you’re ok with that? And know the consequences? go for it.
What's the consequences
I don’t recommend any sealers, that’s what my video is about, but some of these people do. Read the comments It’s your choice
So, it's not recommended for an intake manifold leak (to outside) either?
I wouldn’t recommend it
Anyone saying it's about mechanics making money, just do ur own work. Remove the head, take it to a machine shop. Learn to fix ur own car and u will save a lot of money
Very true!
I paid copper spray sealer and used. Found answer is FXXX shit. Replaced new gasket and then working fine.
And you won’t have to worry about if and when it will fail again because you did it right! Good for you!
No tomatoes 🍅 no peppers 🌶 no onions 🌰 lol 🤣

I understand what you’re saying but temporary repairs are not what I’m about. People that educate themselves can make their own decisions based on their own outcome expectations.
correct all the way Hector,
Which sealer did you use?
Technically all gaskets are temporary, but more effective if done correctly.
No they’re not. They are not supposed to fail. Sealers are a gimmick.
Do u only remove the head to replace the head gasket ? Jetta 2012 se manual
Yes, and whatever parts are in the way to remove it.
Bro I got cvt Nissan mr20 engine. My problem I loose oil & now water recently I checked the oil and and it's a bit high and kind of like chocolate. What do I do change the engine? & it overheats. I got the car with metal radiator should I put back plastic after fixing my current problem?? Thanks in advance man
Sounds like a blown head gasket to me and the metal radiator is fine as long as it’s operating properly.
@@Motorcarnut thanks bro.. But The engine is made of aluminum
I live in the Caribbean bro & it gets really hot here wouldn't the metal radiator cause problems to the aluminum engine?
No, but if the engine overheated bad it could of warped the engine head and block. So it should be checked for straightness.
@@Motorcarnut okay thanks I understand
I've tried bars leak I spend over 150 bucks buying the carbon fiber bars leak then two smaller bottles it kept spitting them out through the reservoir till one day it just stopped and it lasted one year till the cheap water pump I installed failed , I didn't catch it in time even though I heard the bearing rattling (dumbass) I reinstalled my oem pump and it was too late I had reblown the head gasket that's where I'm at now trynna reseal it I'll let you know if it re- re sealed or if I had to dump the car
Stay away from all those junk sealers. $150 bucks you could of replaced the head gasket yourself already a permanent fix. By watching my videos on how to replace them.
Reseal it with blue devil bro it’ll do the job trust me
@@marcosvg5701 sold the car for 600$ it was a loss not really I destroyed the rear quarter panel Tokyo drifting and someone still bought it , I've actually seen it online for sale and just a few weeks ago I got a letter in the mail that the car was at an impound lot even though it's been a year/s since I sold it
Gasket sealers do work for temporary use. It will get you by for a year or so but eventually you have to replace the gasket
If they do work on your particular situation
I put bars head gasket sealer in my 2000 Nissan and it lasted for a yr
You mean it failed in a year?
Some idiot that had my 99 cherokee XJ before me used some of that sealant, now it has been at the shop for a month with more and more things that are going wrong with it, I wish I had known about that before buying it, I haven't even finished paying for it, but the Mopar 4.0 in line 6V engine has a reputation on its own, as well as my mechanic guy, so I am hoping for one of those miracles, I mean, I haven't mistreated it, I haven't gone rock climbing or anything, plus it is a 4x2, I just use it to take my 3 dogs to the outskirts of the city so they can run around on the weekends, it is not even a daily driver
Sorry to hear that. But still even with posts like your people run out a buy that crap in droves. You know the saying, “ you can lead a horse to the water but you can’t make it drink”
I agree to a point/kind of disagree. Sodium silicate solutions to this issue depend on the location and severity of the problem. Its in no way comparable to a new gasket but it has its uses depending on your intentions and expectations. It can work for 2-3 years in some cases. Others just 2-3 weeks.
I understand where you’re coming from but people’s expectations are they want their vehicle fixed properly and permanently. Bottom line. I can’t warranty liquid miracles.
@@Motorcarnut I agree, it has its uses but only to a point. Thanks for the video and the response.
Blue devil took my Toyota 3 more years.
It's not gonna seal everything because its not made to seal everything. There are those clever people called engineers that design it to work that way. It's not just a glue...
Then how come the manufactures that built the vehicle don't make products like that?
@@Motorcarnut you mean the guys who sell the parts?
No, the manufacturer Ford, Chevrolet, Mercedes Porsche etc.
But Ford does create their own engines, why would they want people to use a sealer? They rather have people replace parts, it makes them way more money.@@Motorcarnut
You want to use a sealer go right ahead. Good luck
I am sorry,I tend do disagree with you about head gasket sealers.I have used the product called GASKET MAGIC on my Mercedes Benz C200 kompressor which had a blown head gasket.This was done in 2018 and now it is 2023,have done 125000 km and have no over heating problems,no power loss,no misfire.This paricular product is used by rally teams and guys that go out 4x4 s in remote places and have proven this product works.Simply follow the instructions step step on the 500ml bottle and you good to go.
You have to realize most of the times it probably wasn't even a head gasket failure in the first place. So when they put that stuff in the engine following the instructions they are probably cleaning out or disturbing a overly neglected coolant system and in turn fixed the problem without even knowing it, then thinking it was the sealer.
When a head gasket fails and overheats the engine the head and or the block warp and no additives are going to fix it. It needs mechanical repair.
If you think it worked for you that's great and I wish you the best but I will never put any sealers in my personal vehicles or the ones that my customers relay on. People pay to have their vehicles fix right the first time, not bandaids.
Why is my car still blowing out the overflow after having the head machined & gasket replaced, it literally still did it on the way home the day i picked it up from the mechanic and before anyone else replies asked am i sure it was done, Yes i saw the head off and because of the design can even see part of the new gasket.
Could be a failed radiator cap?
I just it in new and resurfaced heads only not as a quick fix of its warped it won't work
Of course not.
Dang i wish i seen this video before i just got this put it in my vehicle and paid a shop to do it for me i just wasted over $200 some dollars😢
Sorry to hear that. Shop should of advised you first.
You right i guess I have to try to get a new vehicle go take awhile but I needed my vehicle for my delivery job 😪
@HumbleVon04 sorry about that. Good luck
White foam bubble appears on radiator cap opening on early morning starting engine , k sealer can seal up the gasket or not,any one can help reply, please??
Did you at least watch my video? I don’t think you’d be asking me if you did
@@Motorcarnuthe’s asking the believers, your post has just become a forum at this point since there is limited information out there considering it’s such a case by case thing. A lot of people who want to believe in it come on here looking for validation.
I guess so.
K sealer failed to perform ( why none is willing to answer straight forward???)
Thank you!! I have argued this with so many people that know somebody that has done this repair in a bottle! Its crazy! Blown gasket is blowing air out at a very high psi, how is some liquid supposed to get sucked in and stay there to fix a leak!? Like you said it wont!! The fear of a multi thousand dollar repair makes some try anything I guess. Can't blame them either, but if you find somthing that says it will solve a pricey repair for $40.00 bucks then it usually ends up causing even more damage. No such thing as a mechanic in a bottle! There is mechanic on a bottle, but not in one lol.
Yes, an another thing is they say “ guaranteed or your money back” so if it doesn’t work and destroys your $5000 plus engine they will give you a full refund of $50.00 you paid for the bottle. Lol love it.
@@Motorcarnut they make it such a pain in the a$$ to get said refund also that most people if any at all won't do it! So nobody does the refund then there is no unhappy customers technically!? LoL the best way to be a happy customer with any repair in a bottle is to just leave it on the store shelf and keep walking away with a smile.
Absolutely
1100 bars blown head gasket repair fixed my blown headgasket, it works!
Because where the combustion comes out through the gasket it hits the liquid treatment Which turns into liquid glass...Not all the liquid just that section where the gasket is broken it works if you baby your car and drive it normally people that abuse their engines are always full throttle a lot of times this does not work so well. But it works.
Think your right
I had so many failures that came into the shop that I just can’t recommend these products
What about using Indian glue on a new headgasket.
You never use and kind of sealers on new head gaskets. They have their own built in.
@@Motorcarnut I bought me a deisal dixie chopper with a yanmar from a john deere tractor. Person I bought it from blew the head gasket twice which I was told he used indian glue. I assumed the head was warped. But I replaced and after two years of great service I blew head gasket. In process of cleaning head and block. Just was curious. I remember my dad used indian glue for sealing windshield seals. It always worked. I didn't think would work on head gaskets. Stuff would probably dry and crack and cause it to malfunction.
my car is a piece of crap saturn ion with 200k miles. Its practically a worthless car, it just sprung a head gasket leak. I just need it to run for a few months while I save up $$$ for a new car, I think I'm in a rare case where this stuff is actually worth using. I am totally fine with destroying the engine im taking this car to the junk yard in a few months lol. I think you're right that the stuff is bad, but if you're just trying to squeeze another month or two out of a car I'd say its not a bad thing.
In your case, it makes sense because you know the outcome.
I wouldn't say that it necessarily destroys your engine.
What type of failure do you have?
@Harry_Gersack I had white smoke coming out the exhaust. It turned out I actually had rusted ignition coils, replaced those and the smoke stopped
That looks like a ford ecoboost engine !.
Those things are a ticking time bomb for head gasket failure .
Yep
they are not all the same. many of them have guarentees.
Sure, if it destroys your engine they will refund your purchase price for the bottle you bought.
Changing the gasket isn’t even 100% sure to hold
Depends who does the job but I agree nothing in this world is 100% except death and taxes. Lol
for my car work 2 years
And now what?
Those sealers are only good for leaking water hoses.
Not even that.
no,sir! 1100 bars leak, fixed my blown head gasket..white smoke gone and coolant on my engine oil was sealed..no more white smoke no more coolant on the engine oil, 1100 bars fixed it just follow the instruction it works
@@julaiarnold641 same here I’m a tech lol and other techs sunested a head gasket sealer I had a bottle of bars sitting in my dresser for bad days and now my car runs even better than before
Sealer don’t work, they clog and destroy engines, you don’t thing in my 40 plus years being a mechanic I didn’t try this crap?? I bet you swear by that cream that’s supposed to make your Johnson bigger.
@@Motorcarnut of the head gasket has a huge leak then most definitely won’t work it’s a gapping hole.
