Aren't you supposed to allow the engine to cool down. The bottle says it requires a heating cycle.

@TheGhungFu 6 ай бұрын

Putting the radiator cap on and letting the cooling system come up to pressure may work. That will help force the product into the head gasket. Pretty sure none of these products will work without several cycles under cooling system pressure. No way for the stuff to get into the head gasket while the cylinders are under higher pressure.

K-seal pour-n-go is another rockstar, put it in a 4Runner Straight into the coolant and let it run through the whole system, heater, core and all I think it was less than three minutes. Everything was fixed the hole in the radiator and the head gasket. This is just idling at temperature. This was six months and 4500 miles ago You’d never know there was anything wrong with it

In 1958 the USS Nautilus had a leaking condenser onboard - it was critical to repair the leak as the ship was about to make the famous transit under water and across the North Pole. The Captain had the crew scour around Seattle for Stop Leak (now Bars Leak), a radiator leak stopper for cooling systems. 140 quarts were found and added; the system sealed and the Nautilus made its historic voyage without any further problem. But, a bit different from a Subaru head gasket leak...

K seal sorted out the leak in my head gasket on a Primera P11 years ago. I drove it another 30,000 miles or so and it was still running when I sold it. That was a 2.0L and about 170bph. On my H6 Legacy Spec B though (model year 2008) it didn't work. Worked initally but within about 200 miles the plug would fail! Ended up selling it to them traders that pay jack-all...

We had a small leak in our Nissan Xtrail in the past and used sealant from Liqui Moly with some glittery stuff inside of it. I can't find it online right now, but I can tell you how it worked. So maybe, just maybe, this stuff works the same. At first, coolant was still leaking even after recommended 30 minutes of driving, so we just kept adding distilled water and after maybe 200-300 kilometers, it stopped leaking and lasted about 2 years. After those 2 years, it started leaking a little bit again and we repeated the same process and again, after 200-300 kilometers, it sealed everything up.

In the past couple years I have to fill oil approximately 3/4 quart per 3000 miles. Should I have it repair now which is quite expensive or should I just wait for head gasket to fail and do both at the same time?

About ten years ago I had a hair line crack in my cylinder head by No.1 injector, tried Steel seal and it fixed it.Have never had the problem reoccur. It's made here in the UK but hope you give it a try if it's available over there ? Really appreciate your video's & advise, please keep them coming. Julian.

Ive used it before on a 96 grand prix with a 3.1 and my sister drove it for about 10 years. She sold the car and i used to see it around. Also you have to put the cap on after you get most of the air to stop then drive it around for a day, check it the next day and it theres no more bubbles, then drain the system completely and the sit with the hoses off to let and circulate through the system over night. They add 50/50 mix bleed and all should be well.

It was a customer that didnt want to pay to fix it and I told him if you use that crap its gonna cost you more money because that stuff gets everywhere in the system. When he brought it back a week later i took the heads off and you could see where the sealer did seal where the gasket failed there was all this hard white stuff around it so the sealer must cure when it gets to exhaust gasses. The sealer plugged up the water jackets around that cylinder so it obviously got hot and made the sealer fail lol.

It takes a while to fully seal leaks in radiator anyways I used 2 or 3 bottles plastic at top is cracked. Finally leaks stopped but took a long time just drove it around while keeping coolant level topped up. Total time was over a 4 week time frame first it would stop leaks interemintally then when not completely full then when topped off it would squirter coolant but now has stopped for about a week, I imagine that head gasket may be even more difficult to seal but maybe it would eventually help but I've only used the standard k seal for radiator leak at top plastic housing area horizontal Crack in middle I hope I didn't add too much and won't add any more because I am worried about clogging issues or water pump seizing but for now all good

Do you still have this car? Give Bar's HG-1 a try. It worked for me (for now) where the K-Seal Ultimate failed. The regular K-Seal worked for about 3 months but then it started leaking coolant again, so I tried the Ultimate, didn't work at all. As a last-ditch effort tried the Bar's HG-1 and it has been holding up so far (knock on wood).

@kitfisto1827 9 күн бұрын

You most likely have a situation where the leak requires multiple uses regardless of brand. The Bars has the benefit of sealing up the last little bit of leak that the K-Seal started to fill, but didn't quite get all of it. Reverse the brands and you probably have the same outcome.

@friedryce 9 күн бұрын

@@kitfisto1827 Could be, but more likely I think it's due to the fact that Bar's seals up to 0.015mm vs K-Seal Ultimate's 0.010mm width. I can even see copper flakes where the K-Seal just ended up leaking through whereas the Bar's pretty much immediately stopped the leak when the coolant circulated (maybe also helped by the fact that it's a lot thicker). Believe me, I wasn't expecting the Bar's to do jack s----, whenever I see buzz words like "cabron fiber reinforced" and all that non-sense mumbojumbo, I am super skeptical--like how is it going to help fill the hole? Are the carbon strands pre-impregnated with resin? It doesn't make sense to me and I've worked with carbon fiber professionally. But it definitely worked. I was absolutely shocked that it worked tbh lol.

I used the quart sized blue devil on an 07 gmc 5.3L that was using over a half gallon of coolant every week. I removed the thermostat, crimped off the heater hoses and poured the blue devil into the engine via the upper radiator hose. Topped off the system with water and ran at idle for an hour. When cooled i put the system back together with new coolant. It took two long (20 mile) drives to get it to stop using coolant. So far I've put 500 miles on it, and the coolant has stayed at the same level. Fingers crossed i get a year or more out of it.

Blue Devil, the 'Pour and Go" formulation failed my blown head gasket. Problem w. that product (and possibly K-Seal as well?) is that it is only sodium silicate/liquid glass w/o anything else added to it to increase its sealing properties. I'm about to try the "Professional" blown head gasket product made by Bar's Leak to see if it in fact works. It contains carbon fibers (think "Kevlar") in addition to the usual sodium silicate in order to quickly work on sealing up the leak(s) w/i 15 minutes or so of running, vs. the B.D.-type products that require up to almost an hour of running time to start working.

I bought my v10 excursion 3.5 years ago with a weak head gasket, drove it for 2 years before I was seriously suspicious. Leak check fluid never picked up CO or CO2 but a power brake would make it volcano out of the degassing bottle. It went over a year from that date before any leak check fluid would pick it up. Before anyone says "it's the fluid" I had universal blue point and the gasoline specific from the parts store.

On a Subaru? This is a Subaru specific video. The boxer engine is a different beast. Just asking cause I recently picked up a junker Subaru and I'm seeing a lot of conflicting advice about head gasket sealer.

I used regular oil from a snake and it worked and even made me 100 friends on myspace.

I have used both of those if there going to work it usually takes a few days of driving around for it to work it is only a temp fix if it dose work but i have gad blue devil stop a pin hole leak in a intake cooling line on a 4.2 in a f150 well it was a buddy's truck u should by. Pas the heater core. Usually people that use that stuff are people that cant aford to pay someone to fix it or people that are too poor to do or cant take the time off me personally its because i couldn't afford eather to take the time off or pay but i usually do that stuff myself everything thing is too expensive

Has anyone ever had any of these block sealers work ??

I've been using blue devil for years and never had a problem. But I always take out the thermostat , put the radiator cap on and drive it around for about an hour or so then drain it and replace the thermostat. And it was mostly on North star v8 cadillac engines. That's what it was designed for

These only work on small head gasket leaks and not bigger opened leaks.

It would have been cheaper to put sodium silicate concrete sealer in it. It'll probably work the the same as Blue Devil and k sealer sodium silicate is the special ingredient in all that snake oil

People always make videos on this stuff and then they use it wrong and then say it's a bad product. Pretty sure the cooling is like a key part of the setting process. Also this stuff is meant to fix completely blown gaskets or I don't know how bad yours is but these are mostly more effective when you just first start noticing symptoms of a bad gasket. They were good for that no one says it's going to miraculously replacing the entire gasket.
