Blue Devil Head Gasket Sealer: 1 Year Later

This mechanic Mike at Scott’s automotive, is a rare breed nowadays! I’m a retired mechanic and I have people come to me all the time being ripped off by shops! Props to Mike and please stay strong brother!!

[@israelmurillo2143]

Awesome man!! I had a bad blown gasket in my Toyota Matrix last year and decided to retire the car. Would’ve been crazy expensive to fix. It’s been sitting for a year now and decided to try Blue devil yesterday- (why not). Car now is back up and running like a champ... ridiculously impressed. Can’t believe it worked

[@TrailBendersOverland]

Wow!! What a story! Congratulations and thank you for sharing.

[@joshuab464]

Heck yeah!!

[@whisperingoutdoors]

I hope it works for me this way.... I'm still scared...

[@reinieracostavelez972]

Hey guys i recently used it and it works. My question is how long should i use it? My mechanic said after a month working i can change to regular coolant. What can you say about it, please?

[@fivestring4653]

That's awesome !!

[@mhildack]

I used it for a heater core leak 3yrs ago. 55,000 miles later 👌👍. Did a flush first, ran the blue devil with water and drove it for a couple days with no thermostat, drained it and refilled with antifreeze.

I posted here a few months ago that I have a blue devil repair that lasted over 100k and thought it finally failed. I was wrong, still good 120k and counting it was my water pump. Original motor 04 4runner 4.0 V6 with 318k did the 5 hour intensive blue devil fix for the head gasket. Worked for me.

Not only were they willing, but Mike knows how to talk to the audience too.

[@TrailBendersOverland]

Right!? And he was all nervous to be on camera. At least, he said he was.

[@EEPasaurus]

This video is giving me the confidence to dump some of this Blue Devil in. I have a 2004 4runner 6 cyl, 4.0L, the ones that are notorious for this gasket issue( my misfire was in cylinder 6.) Luckily I have never had any overheating issues so far but I am mostly a city driver. It had been acting up for quite sometime before I finally let it run rough on idle (on a cold start) to run the code. What I would usually do is give it some gas and it would push enough water out of the cylinder head after heating up and run fine. I took it to two mechanics where after many attempts at the easier stuff (Changed spark plug, plug itself, fuel injector seal, etc) I finally decided to ask him to do a pressure test on the coolant system from reading much of this issue. After that he said it took two days for there to be enough fluid to see physically. The second mechanic ran a camera down the cylinder and could see a slight amount of water to verify the other mechanics diagnosis. With that being said, it must have a very small crack in the head, hopefully enough for me to get my full 5 years out of it I originally wanted. So far I have had it for three and only put 30,000 miles (extra miles) on it. Right now it is around 177,000. So if Blue Devil can get me another 30,000 to 50,000 ill be a happy cat! Cheers to all the other 4runner owners with these shitty gasket models and issue. Within the week, Sunshine will get her Blue Devil. Now I need to decided if I want to trade it in or just let her see how long she will go.

[@TrailBendersOverland]

Sounds like we had a pretty similar issue. Thing is, you could trade it in even after the BlueDevil. For under $100 you could be driving again with no leak. Sounds like a mild leak and BD would probably work great!

[@EEPasaurus]

UPDATE: Blue Devil did the job. So far I see no more bubble in the radiator when it is topped off. Once it idled for the 50 minuets, and I drove it for a bit, the check engine light went off. I did not need to clear the code, it went off on it own. However, the traction lights are still on and I'm going to pull the battery for a few minuets and see if they will go away.

Mine lasted about 5,600 miles before it failed. Not bad. But it ended up being the freeze plug. Large hole that was a little harder to seal. But great job and great memories from the 5,600 miles driven. Mayne it would've lasted longer if the hole was smaller on the engine block.

I used blue devil and I really thought it didn't work for the first month. The white smoke went away after a couple days but the engine kept running really rough. A month later and a couple thousand miles, it started running really smooth. I cleaned the spark plug that used to get really fouled, it was pretty clean compared to before devil. Now it runs pretty damn near perfect. Glad I didn't get rid of it in the time it took to work.

I always see people judging others on KZbin but you don't get to know someone through a screen, Everytime you see them there's a camera on them so usually they aren't they're normal self, people these days man, I swear.

This post will be shadow banned by Communist Google: . That's so true, You can't just go by how they behave on camera. What shows real character, is how they behave when they think that nobody will know. But when nobody knows, you usually don't know, so it's nice to have them on camera so that you at least have the evidence of what they claim. And of course, businesses will often be willing to do a little more, for some advertisement, so it should not be a surprise when a business is willing to spend more time when videoed, giving them a return on investment.

I believe BD is mostly sodium silicate which is rigid when cured, glass like. It works well on alu head and block as they expand and contract at similar rates but if you had an iron block with alu head it won't work as well. Due to micomovements of the block/head eventually they will fail as sodium silicate has no give.

Super good video brother! Question for you, as to what product and how much you think I should use. I have a 1995 Subaru 1.8L 4-CYL boxer Impreza, 177,000 miles. I have 76 and 78 PSI dry compression in #2 and 4 of one head (driver side). This started a few days ago, we noticed while on a highway trip the power was weak and I can hear it missing as the RPMs drop from driving to idle. I don't have overheating, excessive oil consumption (drippy seals, I add a quart about every 900 miles), smoking, or fluids cross contamination. I'm waiting to have a leak down and another dry/wet compression test at a different shop. The first shop only did dry compression and wasn't too bright or helpful. If I end up having a head gasket leak between those two cylinders, what products would I possibly try to mend it? It must not be too bad of a leak, whatever it is, for the compression to build to 78psi dry. The other two good cylinders are 130ish psi. If it ends up being a valve leak, what products and strength could I try to get them clean? After cleaning, I will have valve clearances checked, as it's probably never been done. I want to see a complete test of all products on all sorts of leak sizes and places. But probably unlikely to ever be done.

[@tonyttran5172]

I had my car overheat and water keep boiling and overflowed over the radiator reservoir. I brought my car to AAACO Car Care. The technician tested and checked it, he concluded the car was blow heat gasket. It costed me $95 for his test. I followed your information by using BlueDevil step by step.. Now I can run hours. But at stop signs or at red lights the car is a little higher than normal (the needle show at 55-60% than normal.) Plus the rad reservoir sometimes still boils and a little overflows. But when I drive without stops, then the temperature is lower than normal.. Do you think I still have blow head gasket? I don't see water in the oil stick and oil cap has no milk chocolate color. No smoke comes out from exhaust pipes.

[@TrailBendersOverland]

Sounds like there might still be a small leak honestly. If there’s bubbles in the reservoir then that’s most likely exhaust gas. Did you leave the blue Devil in for a few days of drain it all immediately after.

Hey man ,I been looking for this vedio what was the steps beginning to end? Blue devil (how much qt need it) Appreciate

[@JoseLopez-nv7tg]

I thought my engine was trash I mean I had coolant in the oil I had rough idle and white cloud smoke honey smell Was even difficult to get it started and keep it running while I did the whole process , I'm going on 2 weeks Its still running now , Sims 2 completely sealed After a second application because of 1st application Didn't give it time to heal and was towing a trailer

[@jimdut795]

Is the Blue Devils still working?

[@gizmo33rd]

It's been over 2yrs now did it still work

[@thehighlandcruisers5194]

How would be the procedure if you have timing chain cover leak, would you pour it in the radiator?

[@obxguy1]

$6k for a HG on these newer cars. I’m sorry, but I’d have to park her, buy a manual, and do the work myself! I know some can knock this out in hours but if it takes me a week, it’s still worth it!

[@juanc5149]

I just did a head gasket job… and It’s still bubbling at higher rpms. Or every 10-15 seconds. :( My symptoms were on summer time with prolonged driving at high rpm. Exhaust gas would get into the coolant. And overheat. Got my head completely rebuilt, the head was super straight, the block, I made it straight. I didn’t find any cracks in the block that I could see. So I’m either a hypochondriac I have a porous block. Or the crack is in the bottom of the cylinder and obstructed by the piston.

[@bensollman8882]

Many cracks can not be seen with the naked eye.

[@juanc5149]

It was fine. The car and head gasket seals fine.

[@BryanHannaActingReel]

So I have a V6 with a manifold leak I was going to use the Blue devil on but someone was saying it might clog my heater core, is that true?

[@alejandrorolandi]

Hi there. It seems another year has passed since this video. May I ask, is your engine still running ok? Thanks bro!

[@enriquesilva8952]

I would also like know how is that engine running

[@alejandrorolandi]

@@enriquesilva8952 I needed up adding this to my radiator 3 months ago and it worked for me, so far...

[@angelcolon4361]

Does it turn off check engine light once it's applied correctly

[@carlawilliams9090]

I have a similar case as you I have a small combustion leak in the coolant and only gets warm when I push the car, my question is did you pull any plugs to run blue devil?

[@TrailBendersOverland]

We didn't pull any plugs.

[@leahjohnson5127]

Will this work for my 98 grand marquis ls.I’ve had a tune up, intake changed , and thermostat and radiator flush .On regular roads the temp hands rises and drives a rough but on the highway it runs great. I’m hoping this will work

[@Miles-wy1zr]

3 years. How’s it going?

[@mauriciorobles5132]

Hi I have a 4Runner with the same issue can u link or tell me exactly what blue devil u used please

[@collinsmwangi3744]

Hi man...hope you have been well. I am still curious if your four runner is still working? and if not are you going to change the gasket? Watching from Nairobi, Kenya...cheers!

[@robertbaxter4021]

Do you think it will fix a leaking freeze plug?

[@michael5cott]

Hows it holding up now as the video was 11months ago

[@seregagoldeni]

No it was 3 years ago haha

[@ajwrighter]

Almost a year now... any issues or is it still good

[@kirbyammonsjr8491]
