​@@UncleTonysGarage If you had a car in good condition but had really high mileage. Could it be a good idea to add a brand thats known to work before you start have any problems? On my 93 S10 4.3L V6 I thought I had a slight headgasket or radiator leak because my coolant kept getting low. So I figured I'd better add some HG/radiator repair before it got worse. Turns out it was a bad radiator cap. Allowing some coolant to evaporate off. But the HG/radiator repair #1 didn't hurt anything #2 after adding it, I never got any HG or radiator leak. I drove the truck over 200k until it was rotted out, engine was worn/low compression & transmission was close to dying.

Electrician here. A good preventative method to avoid coolant electrolysis is to measure the coolant DC voltage to ground with the engine running. Over 0.4VDC indicates damaging electrolysis where the coolant needs to changed in iron blocks. 0.15VDC for aluminum.

I’ve actually used this sort of oatmeal stuff a couple times before and it worked! They were last ditch attempts to save the engines for folks who really didn’t have the money for a car in the first place; but I continue to check up after the work and they report that the engines are working fine.

Used a similar product to get home in a pinch, from a long road trip. It did the job, but as the coolant still got a bit low for a while, it found air at the top of the heater core and sealed that up really well.

Chris Fix did a really good video showing it CAN work, but depending on how severe the issue is, your fix mileage will vary. Some products also incorporate other "fillers" in to help strengthen the repair. Ultimately I am with you, if you need a bit more time in your clunker what have you got to lose. But it you can afford to fix it right, do it!

I'm a used car dealer, I'm all for "financially constrained repairs". Having said, after numerous experiences (mostly fails), I won't try liquid head fix. I will use smaller amounts of less aggressive liquid sealant for less severe leaks after certain repairs, mainly intake gaskets on engines with a V configuration, because I've had numerous fresh gaskets leak from surfaces with an imperfect that's just enough to drip over time. But even then, I'm still replacing the gasket, just using the sealant in conjunction. I'd have to find the TSB, but Ford recommends a certain coolant sealant (essentially Prestone brand) in combination to gasket replacements. Having said that, I agree with you, if the car is soon to be scrapped, there's isn't much to lose.

We have a 2001 Camry with head gasket sealer, it's been working for a couple years now but the car doesn't get used much or drive far. It would be in the junkyard if it didn't work, the car isn't worth doing a job that big. Cylinder one was getting so much coolant i had to remove the spark plug and let the water out, twenty minutes later it was "fixed." I'd definitely call it a win this time.

It’s more of a band aid for a shotgun wound.

tried "Stop Fix" once and it went straight to the heater core under the dash. but in the good ol' days, guys would crack a raw egg in or load up with ground black pepper. it would get 'em home, and then to unplug the mess, pour in some laundry detergent and run the engine--that would act like a washing machine and clean out the organix plug. then you had to flush it all out and accomplish the real repair

From experience here: 4 years ago I had blown head gasket in my 1962 impala Lowrider. Cloud of white smoke out tailpipe, the oil looked like gew and milky all built up on the lid. Used a bottle of this as last resort Hail Mary attempt. Which was a success. I have been driving it every single day for 4 years since then. And it’s doing better than ever

As a kid, I was dubious about these products. I took the time to understand the chemistry, and was shocked to see this stuff can work. I have personally seen the stuff work on minor leaks of the head gasket and even a radiator. I have seen these products stop surprisingly big leaks too. Thing is, most of the time, the folks I know, including myself, have used these as a temporary band-aid till fixing things correctly. In my case a few years ago, I used a bottle of stuff to seal my head gasket. It had to last me just a couple months while I got the stuff ready to do the job right. And, it held up. I am glad that it happened in the summer so I could run straight water for that time. I also see people try to use these as permanent fixes and.... I have yet to see it end well.....

Tony, how did the old bars leak stop with those black pellets work? When I was a teenager I bought an 83 Mustang with a 3.8 sight unseen. I had to drive it back 3 hours. I got it running and the guys driveway, when I went to fill it up with water I found out the freeze plug in the back of the head was completely missing. So I jammed one of those rubber ones in there and filled it up with water, in a few minutes I found out it had a bad head gasket. So we threw three bottles of the bars with the black pellets in there and started driving home after about 15 minutes the car settled down and actually drove great. So of course 19 year old me got cocky and went to go past someone and blew it all apart all over again. The most amazing thing was when I shut the car off the engine spun backwards.... we put another two bottles in it on the side of the turnpike, and I made it home. When I tore it down I found out cracked the heads.

I never had any luck with this stuff on head gaskets......sometimes you could buy some time on a radiator or intake gasket tho. Personally I liked the old Barr's Stop Leak that looked like brown pellets in a slush.

Dont make a poor family junk their cars or get more in debt with crappy lies. They work for over 10k if you are not stupid and step on gas. My jeep has it for 8,000 miles, no coolant used yet. No more steam from exhaust either.

I've used this stuff three times. Worked two times. I don't know why. I think flushing the radiator helps before using it though. I figure it is worth a try at 75 dollars a shot rather than tearing down the engine without trying.

I've sold a bunch of different products over the years, personally my favorite was Bars Leak (which claim to fame was used to fix a leak in the USS Nauilius which was the first nuclear sub to travel under the North Pole) and K Seal. Bars Leak fixed my $300.00 78 Malibu. Used K Seal on a friend's car that was driven dry. After 2 applications it sealed the head gasket (lasted 6 months before it gave up the ghost--300K motor). It's worth the gamble and K Seal comes with a money back guarantee!😆

Interesting , Thank You . As to towing with the Cherokee , When I was farming I towed 10,000 lbs (10 Miles) even with 220,000 miles

Put some of that in my 4.0 when I had a leaky radiator and while it worked for a few months, it eventually gunked up the radiator so bad the motor would overheat under load. Had to replace the radiator, but by that point I did it myself and it was a great learning experience

I have used this for my trade in car to a car lot once .

For cooling system leaks including cooling system leaks in head gaskets, heater cores, radiators, cracked heads or blocks, the best stop leak repair I have found is going to sound strange. I use regular evaporated milk that is used for baking. It's cheap and works better than any of the stop leak products sold. It is the only one that is accepted by John Deere for use in their equipment that will not void their warranty. It won't plug anything except for the leaks so won't mess up heater cores so you will still have a working theater too. I've used it in cars and after 7 years it's still working fine.

Rock their world, Uncle T. 🤙🏻💯🤔

yep, my very first car I ever owned was a scam covered-up with that from a private seller. Didn't do too bad. Got a used engine and found a decent mechanic to replace it cheap. Learned a lesson.

I tried a radiator stop leak and it worked for eleven years and approximately 80k miles. I don’t think I’d try head gasket stop leak

People don't believe me when I say the xj can tow well, so I'm glad to hear thats what you're going to try. interested to hear your thoughts. I've towed a car long distance with mine, about 4500 pounds total I think. I just kept it out of overdrive, and it handled it just fine at 70 mph. I have a transmission cooler and HD springs. It never got hot and I never had to slow down besides for one large hill. The 4.0 makes peak torque at 3000 rpm, exactly the rpm you sit at doing 70 mph in 3rd. Great at towing for what it is.

Great information, very interesting!!

The real question to ask is not will it fix the issue, but will these additives cause damage elsewhere. Professional mechanics tend not to use stop leak unless it's a factory additive (read: Cadillac), because we've dealt with the aftermath. Some of the good (bad) ones are: fix a flat, A/C leak sealer (which gums up refrigerant recovery equipment), engine flush, etc. Tony, you should mention the 2000-2001 Jeep 4.0 COP engine that is known for cracking heads. All the ones I've seen have cracked right below the oil cap in the valve cover.

This stuff has made me so much money over the years lol.

Dear Uncle Tony: A while ago I recall a story about the Genesis of the Plymouth Duster. You said that, to accommodate Disc brakes, the front Wheel base was an inch wider than the rear. This, in spite of the fact that it could have been rectified by a readily-available off-the-shelf Mopar rear axle that is one inch wider than the Duster's." It'll bolt right up!"

Oh, actually it wouldn't be the first. Actually its the best way to put those factory rallye wheels on. But all you really need to do is pick some wider wheels for the rear with more dish and effectively about the same offset inboard. So, yes, staggered setup. Fills those extra wheelwells nicely (Maybe roll the inner fenders a bit if you go nuts, but I ran like 245/60s on my Duster, wasn't too radical but looked and ran right, and does a perfectly fine job of increasing your track in the rear, basically. )

It worked so well I just bought another bottle of it and carried plenty of water if it let go again. It did many months later and I treated it again. Went for much longer, like a year. In the end I just kept renewing it every time it would overheat. I sold it on cheaply in the end - it had done its duty well.

Can't remember the name of it, but its in a slime green round bottle with a weird radiator-cap shaped lid. Admittedly, the kind of head gasket issue you have, NOTHING but a new head gasket [and maybe some milling of the head to flatten it, and the deck as well] will fix that.

“Mechanic ina bottle”😂 Great info and video thank you!

I have seen some of those head gasket sealers lock up the engine.

I used that stuff in my 1997 bmw 328i after over heating it. The head ended up being cracked between the coolant jacket and intake valve and it would hold for a year or So, I beat the crap out of that car every day too. It would eventually fail and I’d put more in the coolant and it was good for another year. Got me by for like 3 years till I eventually swapped a rebuilt engine in it.

Most times liquid sealers work like "Bondo" applied over rust. May work for a while but the underlying deterioration will continue. Better to perform a proper permanent repair rather than that band-aid type approach. Many old-timers used to carry a vial of pepper for emergency temporary stoppage of minor engine and radiator coolant leaks. Too much would cause clogging and overheating. Again, better to perform a proper permanent repair.

No water in the oil, no water in the cylinders, no residue in the radiator and we could not figure out what it was.

I had a ford 300 straight six that i over heated & cracked the head. It would go down a cylinder & run choppy & just blow white smoke that would fill a entire walmart parking lot! 😅!! But i didnt have the money to get a head to fix at the moment so i bought some of that stuff. I was able to drive it another two yrs on that cracked head with that stuff! It would sometimes break open & it would run choppy for a few miles & blow white smoke but after some run time it would seal itself back up & clear up & then run on all 6 again. It got me by! I did eventually buy a head from a junk yard for $100 bucks & change it. Still runs today. Over 250k miles! Loose as a goose! I did have to change timing gears at one point. But never a rebuild to date.

This stuff just saved my stepsons pos 305 plow truck. New engine next spring. It works. Not a good repair But a repair none the less.

I'm currently dealing with the aftermath of headgasket sealer on my 03 Nissan. Previous owner didn't maintain the car and overheated it and blew a head gasket. They poured head gasket sealer in (not sure what brand) and drove it until they sold it to me with a broken off spark plug in the head. I repaired the plug and then blew the head gasket again 2000 miles later. Long story short: EVERY PART OF THE COOLING SYSTEM was damaged in some way. (Block, head, and radiator full of concrete-like sealer, all rubber parts swelled and degraded). I'm replacing all hoses, thermostat, waterpump, the radiator and I dissasembled the block to chip away all the sealer and then sent it off the be hot tanked at a machine shop (engine is getting rebuilt because they also didn't change the oil on time). There might be some brands that actually do the job without destroying everything, but I definitely have my doubts after this.

I must be lucky twice. Had a 1971 360 F100. Had some engine fluttering and extra moisture coming out the tail pipe. Put some block and gasket seal in it and after about a week of short drives, straightened right up. Same thing in a 1980 302. Seems good to go.

AWESOME vid UT. MOPAR 4 EVER.

I had good luck with some stuff sometimes. Recently I removed a cylinder head blown head gasket and the coolant holes were almost completely clogged from previous use of radiator sealant!!

I Had a friend with a 2000 GMC Denali with a small but steady external leak (water) and he needed to get home to Michigan from Phx. I used the very brand your showing and followed the instructions VERY CAREFULLY and it worked!!! He got home to Michigan with no problem. But it's certainly not a long term fix. Would I use it in one of my vehicles? No!! I would have rather my friend bought a plane ticket! But hey, whom am I to judge?

My experience YES it did work. 98 expedition and 97 cobra. Better the prep better the outcome. Remove thermo, flush LOTS of fresh water thru engine while idling. Then let engine cool overnight. THEN add product add water , idle 45 min. Replace thermo. 8k miles and cobra 6k redline no probs.

Another excellent video.

You are my HERO!!!!

Electrolysis can't happen with proper coolant, because the coolant corrodes the metals to protect them. Just change the coolant if it's gone bad.

Tony I've worked on many of these 99 to 01 XJ's... Almost all of them that fail between 3 & 4 is due to a bad 0331 head casting. This is likely a cracked head, look it up.

We used to stop at McDonalds and toss a packet or two of complementary pepper if we had a coolant leak, usually from a radiator tube joint.

I remember as kid my dad using stuff called Bars Leaks. It was this liquid with pellets made up of coconut husk from memory. It always fascinated me watching the liquid go from chocolate brown to white when water hit it.

Have a 92 Silverado, head gasket blew. Oil looked like a chocolate shake. Used some blue devil, leak appears to be sealed up. Got a new to me motor to install in a couple months, but if I get a bit more on the old one I will be happy.

The vibration could be a worn chain in the transfer case

My dad bought a really nice Cadillac sedan deville, early 2000s model for $500 and it had the notorious North Star head gasket problem, he dumped some mystery juice in and drove it for about a year before it showed signs of letting loose

Interesting but what Tony has failed to share is that these can’o’fix options wreak havoc on the rest of your cooling system and your for sure gonna be in deep if you choose this route.

A time you're exactly right about everything you said about the Blue table except I believe it has ceramic dust, yes I've used it last 2 years but not on a compression the compression leak 🤠🚩

Had same issue with tail shaft bushing. Couldn’t find much help on it. You should do a video with fixing that in it.

The blue devil one is the best it’s the only one I’ve seen work long term. But it has be the one that requires you to drain coolant and remove thermostat there are 2 formulas. My friend’s daughter(16 years old)first car a little Nissan blew the head gasket. I blue deviled it and she drove it through college no problems.

I "fixed" a BAD head gasket leak on a turbo Volvo with Blue Devil. I consider it preventative maintenance in a Subaru, every cooling system flush lol.
