Do Head Gasket Sealers Actually Work (FULL 2yr TEST with Engine Teardown)

1. So it was brought to my attention that my house phone number is on the oil analysis sheet. I am waiting for YouTube to blur it so in the meantime, please dont call it…

2. I've used the bars head gasket repair bottle that worked great , the bottle saids permanent but not true I added about 3 bottles in 2 months . Worked well after 2 months engine was toast repaired the head gasket eventually . I would use the bars head gasket repair bottle again was around $29 bucks for a temperary fix that lasted 2-3 months

3. Good video but 10k miles is a very SHORT term fix. Thats maybe 6 months of driving for a modern car. 2 months for me.

4. K seal worked on non compresson water leak on OM046 t1n sprinter for one year. Then of course it starts leaking again.

5. Outstanding I still want to know if the others would work better

6. If you used the head gasket sealer and it worked for a few years and it has another leak can you just reusue the sealer again ?

7. So that head warped from it over heating when it had the head gasket leak ? Can that happen with just 1 time over heating or does it usually take a few times of over heating to cause that . ?

8. Should you flush the coolant after the head gasket fluid seals? If it doesn’t hurt the coolant system, would it be smart to add some to a 200,000 mile/20 year old vehicle as a safety in case a leak does develop?

9. I have problem… oil pressure warning ligh coming very often, sensor and oil pump replaced ,run better but still have the problem..what can be

10. Great video. Anyone who knows cars a little has had to help a gramps, a single mom, a kid on this one. I think the mechanism of sodium silicate is probably not just an evaporative deposition, but chemically triggered too. If so, the gasket or sealer (Subaru) might work better or worse. Not really sure but „water glass“ silica has a complex chemistry to become water proof.

11. ?? Do you recommend any particular, heater core sealer, or if it's a even a plausible option?

12. Says use the right coolant. Bro that's a ford that you just put European coolant in lol

13. You didn’t drain the head gasket sealer ??

14. Copperhead volvo s40 5 cylinder bad leak it done great

15. Can i run this on my audi 3.0T supercharged?

16. Can i use it before my head goes like a preventative thing ya know..ima try it on my perfectly running dodge caravan

17. What about the block sealer portion? If the block has a crack?

18. Thats trash

19. I have a question. My head gasket is currently leaking. It’s an external leak. Will one of these work?

20. DO NOT USE ANY OF this JUNK Repair it the Right WAY STAY AWAY from this CRAP ,use and you be Paying MORE .

21. The amount gratitude owed to ChrisFix.. dude should be testing gasket sealer on a Bugatti that he beats up as a daily.

22. I used the blue bottle light blue and it didn't work for nothing

23. I tried your method 2 months ago, and yes the car is running great and have not seen anymore issues, hopeful that the issue stays resolved
    Thank you for saving me some serious money.

24. This video is really good and informative thank you, we need more like this with different products.

25. I'm a retired chemist and did a lot of research on this subject and settled on Blue Devil for my '97 Altima AND my '05 F-250 (diesel). No more head gasket issues even after several years of driving both vehicles. One proviso– follow the directions on the bottle to the letter.

26. I stopped watching at 2:29 If you have a demolition derby car and you want a few more heats. by all means try this. On many modern cars the coolant passages are so small at the head gasket any stop leak will plug them off. Now you have no critical cooling to certain parts of the engine. If you can't afford to fix a head gasket, you sure as hell can't afford to replace the whole engine, or the extra 1000 dollars in labor trying to get the stop leak out of everything

27. No they dont work and if they do it's a very short fix

28. I just bought a head Gasket Sealer. I have a 2012 Jeep Liberty 3.7 liter. I believe I have a very small leak between the coolant and the combustion chamber. Upon sitting overnight after driving it When you start up, you get a puff of white smoke with a misfire in cylinder 2. Engine light is on, and the car runs rough at first then clears up. After a few days of driving, I have to replace the coolant. The brand of sealer I purchased is BAR'S LEAKS Head Gasket Fix. The car has 90K plus, so I'm hesitant to use it just yet. The other side of the coin is this…If I decide to fix it, I will most likely replace the motor seeing that the amount of work to do the head gaskets are almost greater than replacing the engine itself, which means as a last resort, I will use the head gasket fix. Any suggestions???

29. Amazing video!

30. Mazda RX-8 Rotary. Blown internal rotor coolant seal. Same as a head gasket in a non rotary. Dealer said engine was toast. Full white smoke screen out the tail pipe. Independent said engine was toast. My son and I (his car) pulled all the plugs, grounded the plug wires an spun it over. Tons of water came spraying out. We then followed the exact directions in a single small bottle of "K-Seal". It was a super hot day. When it was time to drive it, I took it on the freeway for about an hour all the time watching the rearview for white "smoke" and the temperature gauge expecting it to overheat. It ran perfect. I turned around and drove an hour back on the freeway. Parked it and sat over night. I fully expected it to not turn over or spray white smoke if it would even start. It started like new….. He drove the car for another 37,000.0 miles with not issues and sold the car.

31. Wow!

32. @ChrisFix Epic honeypot troll X2. beer salute. I was a little step backed by the high speed audio, but I'll watch the full vid because of the troll.

33. Real steal best head gasket repair I have ever use hands down sorry all that stuff he has sucks. Just follow the directions to the Tee ok later, now when I did mine, I was burning antifreeze u can smell it but mine lasted forever thanks guys bye bye. Oh ps do not use it twice if you do it could be really bad. Do it once only so cold engine dump it from bottom hose, dump the resovior container put everything back together pour in real steal head gasket liquid and add your 50/50 antifreeze then take it for a ride for a 20 min 1/2 hr or whatever direction say your good guys later. 78.00 worth every penny……

34. But why the engine failed at the end? If it had enough coolant and there was no leak, because of the bad oil?

35. Thank you sir from South Afrika

36. Should have poured in another bottle

37. I have had great results using K seal

38. I don’t got problem with my cars just like watching Chris

39. Question…how can you tell if head gasket sealer was used on a car you're thinking of buying?

40. Great video bro. Nicely done! Thank you so much.

41. The annoying thing was you didnt get it to 200k miles

42. I used rad-seal before completely clogged up the radiator
