Can You Fix a Head Gasket with a Chemical Sealer?

[@shernandez505]

I used Blud Devil gasket sealer last year on our 2006 Honda Accord LX. I was trying to figure out why anifreeze was spewing from underneath the reservoir cap all onto the engine. Changed the cap, changed the reservoir, changed the little reservoir hose...still the same thing. Researched and read it was head gasket going. Oh hell no I wasn’t paying $1,200 plus for that. Came across this at NAPA and said, “ What have I got to lose except $40?” Followed the instructions to the tee including removing the thermostat. By the following day after doing the flushing and runs, the problem was solved. Kept checking it everyday as my son drove to college/home 80 plus miles round trip each day and still, no problem. And then...my son wrecked the damn car 5 months later totaling it (he was fine). But at least I wasn’t out $1200 plus on this repair!!! This stuff seriously works..but like the man says, follow the instructions as they state on the bottle label. I’m a Blue Devil believer!! Good video!!

Hey I got a Honda civic lx with a blown head gasket ima try it out but do you know how long it lasted your son???

[@melissamcgee833]

I have the same issue with my 2004 civic. Coolant will blow out of the overflow cap when driving. It's been doing this awhile so I just add coolant before I leave. Hopefully this will work!

[@shernandez505]

It will work but you have to follow the instructions to the tee. Tedious but a small price to pay rather than a $1500+ repair. I had failed to respond to prior comment from Nathaniel P, it never did it again. 5 months later driving 80 miles+ round trip daily, repair still held. Ive since used stop oil leak on my tahoe and rear main differential, stopped that oil leak. All Blue Devil products work great! I’m a believer!!!!

[@shernandez505]

@@melissamcgee833 just make sure its not your radiator cap; rubber underneath wears out with time. Rule them out. No harm in replacing the cap. Process of elimination. Monitor each daily to rule them out.if it still continues for a couple of days then use the Blue Devil head gasket repair.. Good luck!!

[@waynesanchez6504]

Used to assist in an automotive machine shop. If you're replacing a head gasket you SHOULD have that head REBUILT at the same time! Why? Because many times a blown head gasket is the rebuilt of a WARPED HEAD. That head should be checked for warpage and whether or not it can be SHAVED (machined flat). At the same time, you will have the valves, valve guides, springs, and valve oil seals checked/replaced as necessary.

[@gigigiseleworld]

Thanks... I don't think a liquid can help.. maybe delay the inevitable ... My valve cover gasket was leaking last year.. had it replaced ..with some white smoke recently.. I thought I was having a an issue with my charcoal canister after it threw a code.. ! Now my thermostat is acting really weird.. so I'm suspecting it's the gaskets.! V6 and it's over 200k miles...

Thanks for the demo and the testimonial. I have a very small leak. I had an intake gasket leak that I've already corrected, discovered there's also a very small external leak behind the head. The leak is so small, I don't even have drips on the ground beneath the truck...... Just see signs of it when looking up from below the truck. It's probably best to do it now since I've already flushed the coolant multiple times, especially the heater core. I think you just gave me the motivation to go ahead and get this done so I can get some coolant back in and call this nightmare done-did. Mine's an 88 S10.

[@chrishayes8197]

A tip I found online and used that worked well - maybe put in a lower temp/pressure thermostat to reduce likelihood of blowing out the sealant. I ran a bottle of Blue Devil (the standard version, not the quick one) through an high mileage '87 Ranger (v6) with a severely blown head gasket. Still had a bit of a leak, so I flushed it again and ran another 1/2 bottle through it. Drove the truck daily for the next 3 years with no leak, probably 25000 miles. It was still running when I scrapped it. (I had bought the truck from a friend who was going to scrap it - I was moving to a new apartment that week, and figured it could just barely make it the 1.5 mile drive before, and save me the cost of renting a U-haul. The Ranger would blow through / boil out almost the entire coolant system after 5 minutes of driving, needing a refill. Worked out better than expected, and I was only out the cost of 2 bottles and the time to flush it! From friends who've used it, sounds like getting it flushed really well (as directions dictate) makes the biggest difference in whether it will work or not. I personally think the lower temp thermostat helped too.

[@user-dx8nj7qj2g]

1:43 i used a different one without removing the thermostat and it definitely broke my thermostat, but i think it fixed my head gasket because no more leaking coolant

[@leontrezjbreyon6911]

Have it leak yet

[@asilaydying672]

A lot of people always leave out a bunch of others too. When doing this be sure to read the directions on the capacity for your radiator. The yellow label is usually for V8 models depends on your radiator capacity like I said. I only used half a container for my 4 cylinder. But I’ve also done both products and the pour n go still leaves behind white residue on your thermostat and I would advise people to drain and fill on the pour n go as well. Maybe let the vehicle cure for a good day. And pour in new coolant on the pour n go along with replacing the thermostat. This yellow one the same method drain the coolant inside it and replace new coolant. Oh also when you pour in the blue devil don’t just put the cap back on. But, be sure to top off your radiator with water until full so you don’t have air in the system and last put on your radiator cap....boom you’ll be set and let idle.

[@tiffanyv4205]

I was worried about him missing that step

[@asilaydying672]

@tiffanyv4205 it's temporary fix I tried it on my car but turns out it was my head gasket. It was done for. Blew that blue devil out and made a mess when it leaked again. I wouldn't suggest it.

[@interstate80.]

I found mine very early. The only reason I discovered this was because I was fixing an unrelated coolant leak and just happened to see some minor symptoms. I’ll give this a shot and hopefully it’ll work. I need it to because I can’t afford to replace the head gasket

Hi mate, great video. One point though there does seem to be two versions of the same product. One version you have to remove the thermostat etc and the other which is called “pour n go” you don’t have to. Don’t know whether the formulation is different but just different instructions to follow!!

[@robertelmo7736]

There is also a Bar's Carbon that works with antifreeze and it is add and go...it works better than Blue in my opinion.

[@Trollet456]

If people changed coolant and flush the coolant system more often the head gaskets would hold up longer. Change coolant and brake fluids are often forgotten things on older cars

I had my 2004 GMC Sierra fixed with head gasket sealant last May, 2020, in AZ, then drove it back and forth to the Valley a few times before driving it all the way home to NC, 2004 miles, where I have continued to drive it all year so about another 500 or so miles. At this point, and at my last service and check up, my mechanic said my truck is running well and the oil is normal.

If that is a code r 350 (5.7) engine , And the engine has a lot of miles and the engine has never had any major engine repairs . I would for sure replace the broken plastic intake gaskets , Biggest source of coolant leaking into the engine oil is the broken plastic intake gaskets around the water outlets of the cylinder heads. After that repair is done ,and you still have issue ( you overheated the engine ) then you should try Blue devil . Speaking from A GM tech who has done these repairs a lot . depending on how bad the condition Blue devil may work

I have a 2000 Grand am GT with 230k miles. It had sat for a 5 or 6 years and when it went back into service, a cracked radiator was discovered and repaired after a large puddle of coolant was discovered. it developed a slight rhythmic rev while idling a few days before that. After light use, one day it's temp spiked to redline. It's operating temp is 218. The thermostat was then replaced. Now it's losing fluid and Ive discovered liquid on the block directly below the head on the drivers side. There is no coolant in the oil and no moisture in the exhaust... only on the block. Will this product possibly work for this specific condition? I only ask because it seems like all the examples ive seen show internal leaks, fluid into cylinder, or fluid into oil....

Got an 88 Ford f350 7.3 naturally aspirated diesel. Have a coolant leak externally only in the front passenger side right under the exhaust manifold. Pretty sure it's a head gasket leaking externally only. No symptoms of coolant getting into the combustion chamber or oil. I'm a little concerned that the blue devil might not work here because it isn't hot enough to get it to harden up. It only leaks if I leave the radiator cap on and the system pressurizes. If I leave the cap off it doesn't leak at all. As rarely as this truck gets run I'm considering just letting the truck operate this way.

I have an old Toyota 2LT engine built anew. All items are new and high quality. Most Japanese, only pistons are Taiwan. The cylinder block is bored out, and new high carbon steel, quality cylinders are inserted. Cylinder block gasket metal TAKOMA. But on the gasket was smeared SHELLAC, and possibly of poor quality. Engine - diesel. At high speeds/tork , it gradually squeezes out antifreeze. Also, with the thermostat removed, it squeezes out 1.5 liters for 80 km. At low speeds, the pressure is less, the inflation of the cooling system is less. The compression was checked by inflating the air pressure into the holes of the glow plugs. There is a slip between the three cylinders. The big problem is that from the 3rd cylinder there is a breakdown into the crankcase and there is a weak but smoke from the crankcase durig the oil dipstick. The question is - Can a punctured, poorly-fitted gasket leak exhaust gas into the oil system like into the cooling system? And is it worth it to apply sealants or change the gasket? Should I use metal or paranitic? On a metal smear SHELLAC or is it not worth doing? Thanks in advance for any advice. And thanks for the interesting videos.

1st thing to do if water is in the oil Change the oil with "USED" motor oil.. With the price of oil and you know its leaking water there is no sense of spending/ wasting $35.⁰⁰.

I pulled my thermostat as suggested, huge mistake. Both the bolts were super rusted and snapped off, had to drill and tap. Water pump and intake are done. And the reason they were rusted, previous owner never flushed system once and only ran water, because "it's a California car". Radiator fluid, or coolant, is important. It has a lower freezing point, but also a higher boiling point AND corrosion inhibitors. This video and the 1st video are super helpful and well done, but please don't suggest coolant isn't important. People are dumb, they will just run water and turn a v8 into a boat anchor.

I have milky oil should I change my oil before using the pour and go cuz I have already replaced valve cover gasket thermostat water pump on it and it coolant reservoir was flushed and refilled and oil change but recently my temp gauge sensor went bad and my reservoir had to be replaced cuz it was burning through coolant I know its a minor issue cuz I haven't really driven it since August of this year

[@tonymascali]

great video. Its been 2 years now. Are there any bubbles yet? How many miles did you get?

[@2carpros]

Still good actually! Pretty shocked! Thanks for watching!

[@Samuelfish2k]

What if a car has bubbles but doesn’t overheat?

[@callmebackfriday2]

I have a 09 Corolla Dual VVT-i 1.8L engine has 185k and it misfire on cyl 4. (P0304), according to the auto shop, I have coolant in Cylinder head 4. Would this work on Toyota and does your leak still good as of today. Thanks so much for helping.

I got a Dodge ram 1500 with the 4.7l with blown head gaskets. I have all the parts to replace the head gaskets a new water pump and all. But I think I want to try this stuff and see if it can get me by for a while and than replace everything I need the truck bad right now. What would you do?

How did it hold up? People say sodium silica can seize up the engine if you got coolant leaking into oil, making milky oil

So my 05 2,5 s Nissan Altima 4 cylinder won't start dealership said it was head gasket how would the chemical work if vehicle won't start it also has 114,on the dash and suggestions

[@2carpros]

A head gasket wouldn't prevent starting. Unless the engine is totally filled with coolant or something crazy like that. Thanks for watching!

[@kendrickwilliams3696]

It would have been nice to see the exhaust smoke before then no smoke after.

[@2carpros]

It didn't smoke too bad it this case. It was just milkshaking the oil. Thanks for watching!

[@Comin_at_U_Live]

The head gasket would need to fail between the cylinder and coolant to see smoke.. you shouldn't see white smoke if it failed between coolant and oil in that case its milk shake on the oil dipstick.. .

What do you do if your thermostat is built into the housing

[@dalebrouxtom]

Are you not supposed to flush the thermostat first?

[@KhanhPham-ev7kc]

Hello everybody! My 2003 civic always makes a 2-second air hissing/sucking sound when I shut the engine off. In addition to that, the coolant always fills the reservoir up and doesn't seem to go back to the radiator. If I don't fill the coolant in the radiator up after a long ride or a few short rides, I'll get overheating. Someone told me that there's a leak from the coolant passage through the gasket to the outside. I don't see it mentioned in this video so I'm not sure if it's a thing. And if it's truly is, does anyone know a way to fix it? Does head gasket sealer help in this case? Thanks!

[@jasminelinares3434]

Ever find out the problem?

[@hx1234]

if the coolant is bubbling in your coolant reservoir, what does that mean? Kinds of looks like air pushing through water. Its not alot. The coolant looks clean though. Oil looks clean too. And no overheating I believe. Does it seej like I have a minor head gasket leak?

Yep. Thanks what it looks like. Thanks for watching!

I did the change the intake gasket there is leak and mix up with coolant is this also works? Thanks

[@indygo1963]

Great video. Question: I have a bmw 528i and there is no radiator cap. Only the reservoir cap. I’ve seen other videos saying NOT to put this is the reservoir but ONLY in the radiator. How is the best way to proceed on this type of radiator situation? I don’t have fluid going into the oil. So no chocolate milk situation, but is coming out of the exhaust and no misfiring yet in the cylinder. But that is probably coming down the road. Please advise...

[@billionaireclub1703]

Hi I actually have the same issue with not having a radiator cap. Can you please tell me what you did. Or how I proceed with this. Thank you

[@briancherry9175]

Pour it into the radiator from the top hose on your radiator. Problem solved.

[@austin_1911]

Do you do the oil change before you do the radiator flush or after?

[@2carpros]

Before the flush. Thanks for watching!

If it's bypassed then you don't need to have the heater on. Thanks for watching!

have a m111 engine Mercedes Benz, mixing water and oil in the engine. Many mechanics in my country don't understand that a chemical like this exists and many think that if the gasket is damaged then the car over heated and the Cylinder head may have warped. Can I use this chemical? I strongly don't think the head warped

[@2carpros]

I'd try it. Thanks for wastching!

[@dwightnutter5353]

I have a 99 grand caravan, it ran Hot, I made it home, changed the leaking water pump, I have water in the oil, now I know where the water was leaking to. Steam coming out exhaust,,,, is it to far gone to use blue devil and at what point should I change oil during the process if Blue Devil is recommended.

[@2carpros]

At that point I would say it is time for head gaskets. Thanks for watching Dwight!

[@GatorRomeo1018]

Okay so do you mean to tell me that the reason people are complaining that the radiator clogs with head gasket sealer is because people fail to flush the radiator after using it? This sounds like the step in the instructions that prevents all the problems this chemical can cause.

[@2carpros]

That is correct. Thanks for watching!

You said don't drain it after you run it with the blue devil also if it requires 50/50 do we replace what we lost in the thermostat with that

[@asfandbabar5635]

If you want 50/50 just drain it completely and add/bleed 100% 50/50, this stuff only reacts to 1 heat cycle (says on the bottle)

This is correct. Thank you both for watching!

[@2carpros]

What? I can't drive someone's car for months and months to prove it worked. It worked in the shop and according to the owner it is still running strong. This is also a whole lot cheaper than doing 2 head gaskets since this was a V6. Thanks for watching!

Hey guys. I have a 98 nissan almera 1.6 litre (16 valves) with hole in head gasket. it doesnt have a white smoke but it overheats on hi revs and it consumpes oil and water like 1 litre per 1000 miles. I cleaned a radiator and removed my thermostat. my question is after i put Blue devil can i run the car without thermostat? and what is better after the blue devil treatment? filtered water or coolant? or can i mix between them

[@2carpros]

Yes you can run the car without a thermostat but it might overheat due to water not sitting in the radiator long enough to be cooled. I just use hose water with coolant concentrate. Thanks for watching!
