Head gasket sealers head-to-head comparison.

I tried all the major brands of head gasket sealers and in this video I share the results based on my own experience, reputations in the auto parts store, ease of use, and ease of money back guarantee.

Here's the link to the KW Form for the double your money back guarantee.

I just used a k-seal head gasket repair and it work, bubble on reservoir coolant is gone and no more over heating, thank you You Tube Academy and people post their knowledge try to help other people to fixed their car especially like me that I'm not a auto mechanic . Head gasket repair it so expensive.

I used KSeal two years ago on a 2004 Dodge ram 1500 (4.7L V8) and it worked perfectly! That gave me 2 years of trouble free driving during a period that used cars went up a great deal. It recently failed, so ive used KSeal a second time, 2 years after, and it is working again. Its not a permanent fix but the correct cost/benefit fix. Id buy KSeal again!

ChrisFix just released a video in October of a 2 year/10k mile test of Bar's Leak Head Sealer and it worked very well. He also said if he had to do it again, he would have likely tried CRC Head Gasket Sealer (not in your comparison). Of course, he didn't really have a bad, damaged head gasket, but a slightly warped cylinder head (1/1000th of an inch or something), so that might have played a part. That little warping still made the car undriveable without the sealer. Finally, Scotty Kilmer had a video a couple years back that said you had to be very careful when using sodium silicate (liquid glass). If there was coolant getting into the engine oil, then the sodium silicate could ruin your engine because it would get into the actual engine and not just the gasket...

sweeeet. that's how you make an informative and concise video without, "here is my dog, " "here is my messy garage, " "here is my bandaid, " etc.

I used Bars Copper on our 1992 Honda Accord wagon and it totally worked. It's been about 20, 000 miles with no issues. For a vehicle with 250k miles, I'll take another 25k+ for the cost of a bottle if Bars.

I drive old cars and trucks. K Seal is my go to in these situations. Working so far!

My car was running rough with loss of power and kept overheating after I changed out several components including the thermostat and temperature control module. Then I noticed a sweet smelling white vapor emitting from the tail pipe after I first got it started from a cold engine. Before it got to operating temp I opened the radiator cap and saw bubbles coming from inside the radiator which meant blown head gasket. I bought the Bars brand Head Gasket Repair and didn't have much hope. But I was pleasantly surprised that it did actually work. No more bubbles, no more steam from the tail pipe, no more over heating. This saved me thousands of dollars.

K seal worked for me . Seems to be permanent drove my civic for I would say 15000 miles still holding strong.

I'm so glad you tried all of these. I've wondered about it forever and NEVER used them. However, now I'm in a pickle...a lady came to me and JUST purchased a van and after teardown I saw a small mar in the deck and had to tell her I really couldn't fix it. They dooped her into buying the thing too! So she answered almost in tears, and said just put it back together and it worked for about 20miles. This might work for her particular problem and I'm going to run it by her. I'll keep up to date with the results too.

I used the one on the far left in box . Worked amazing . Sealed the leak completely.

This was definitely helpful and also K-Seal is the one my mechanic recommends. Did not know about the guarantee though. Just again did put the smaller container of K-Seal that says permanently. Used the bottle before and lasted for about 2 1/2 months.

Thank you for the info, stories and opinions. The BlueDevil stuff is glass btw not metal. If anyone has a Subaru make sure to follow this man's top two product suggestions. Follow the instructions of the Yellow BlueDevil THREE TIMES X3 for best results if any.... and do the difficult head gasket replacement next spring. These are band-aids FYI, meaning TEMPORARY.

The bars leak clogged up my thermostat in a engine that has a very hard to reach and replace the thermostat. Never using there products again. Thanks for the review.

Great video, straight and to the point with no filler.

[albundyrocks]

Sounds like a warped head rather than a blown gasket. I used Bars Leaks on a 600 hp Buick big block. It took 5 thermocycles (heat up and cool down) but it did work. It's a race car so I don't have many miles on it and don't know how it will perform over time but it cured the problem for a lot less work than me tearing the motor down to replace gasket

[jamesmichaelcabrera]

Give you a like. Thank you for the review. I need one ASAP before the Gap gets bigger on my head gasket. I'm glad you're over a thousand subscribers. Keep posting

Before I did my HG replacement about 85, 000 miles ago on my Chevy Sonic 1.8l, I tried 12 oz K seal pour n go and it lasted about 3000 miles before a combustion leak started to pressurize the cooling system again. I then had the time to pull the head and replaced the HG. Well here I am again. 😅😅😅. These engines run at 226F which is for better fuel economy but tar heat puts more pressure on parts. 😢😢😢.
I would like to take it down to 190F but the check engine light will come on.
Next time I will place the best MLS HG out there and see what happens.
When realized I got over pressurization in the cooling due to combustion gas leakage, I made a pin hole on the top of the expansion tank and check the coolant level every day. I am going to get a HG sealant today.
Thanks for your review.

3 MINUTES IN and this guy is killing it ... these companies and their rebates LOL

[greathey]

I like your straightforward way of judging these. I used k seal the small one on three cars with possible fissured head gasket and so far so good.

[willpina]

The problem with a head gasket leak is that you don't know the severity of it. That's why some products will work better than others and you will have tons of people disagreeing on which is better.
Let me just say that no matter which product you use, they will only work temporarily and you can expect the "repair" to last about 5000 to 10000 miles.
