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

มุมมอง 1 388 348

Replacing a Head Gasket can be difficult and expensive. Sometimes your car is not worth fixing and this is where a head gasket sealer in a bottle comes in handy. Do these head gasket sealers actually work? How long do they last? How do they work? What does a bad head gasket look like? Do head gasket sealers clog radiators?

In this video I show you how to use a head gasket sealer to repair the head gasket and test it for 2yrs and 10,000 miles. I then tear down the engine and show you how the headgasket failed, how the sealer worked, and if the radiator got clogged up with sealer.

Here in the UK I used the K seal on a rover 25 with a 1.8 k series engine. I got another 2 years out of mine. My symptoms was a little misfire just above idle and losing coolant. But ran good for the 2 years

I stand behind Blue Devil daily drove a 2003 Pontiac Montana with the 3.4L V6 with over 100,000 miles and it was far to expensive to do a head gasket job on, the mechanic we went through suggested blue devil it just now after three years has finally quit working, but the fact that we we're able to keep the vehicle going for that long shows that this stuff works and can kept it chugging for a few more years RIP Silver Bullet you'll be missed. 💟💔

We (mainly my friend, I just assisted) did this on my '93 pickup truck after it blew out all the radiator fluid on the interstate. Took a bit of work, and it did clog up the radiator (mainly because we had to pour the sealant straight into it), but thankfully we were able to unclog the radiator before trying to drive it. It ran for probably 7-8 months before the fuel pump gave out on me. Not giving up on it - and eventually I plan to rebuild or replace the engine - this was just meant as a temporary fix to keep it running, which it did as intended. The sealants do work, but no one should consider them a long term fix by any stretch of the imagination. Regardless, thanks for this video. It's interesting to see an in depth view of how they're actually working.

Some of these head gasket sealers, recommend flushing the system with water, and not putting in the antifreeze, until the leaks is fixed. Just fill the system with water, and later add the antifreeze. Also they recommend removing the thermostat before you add the sealant.

I had a 2011 Mazda 2 with 128k miles blow a head gasket. Tried the Blue Devil sealer Twice but it didn't work. I was so disappointed, mostly for the fact a Mazda should not blow a head gasket that young when taking care of the engine. Another thing is the Mazda 2's transmission fluid is cooled by the engine coolant as well. So when the gasket blew, bad coolant got into the transmission fluid and all into the transmission. I was pissed to learn that. No more Mazda's for me unless they ever fix that.

I have blown head gasket and followed the directions using steel seal. I flushed the coolant system and added the approved coolant and sealant and then drove on the freeway for 5-6 miles and let the car sit overnight. Next morning it turns over but won’t start. Anybody have any ideas? Thanks in advance

So I just did this yesterday and so far so good, needed to top off this morning with a few ounces of coolant. However now I am experiencing a lot of jerking or misfire while driving at a steady speed. Once I get the rpms going it clears up. Any ideas?

I checked the oil it’s super clean but I have lost about 1 qt of oil since the last oil change. A recommendation would be most appreciated. Many thanks as always.

Bought a cheap 97 4.2 F150, had a present oil and coolant leak, checked out liquid sealants- bought Blue Devil /Coolant system flush for new coolant to be added. Read and followed directions for the can and checked out a couple suggested videos. EVEN while using the truck for an emergency call - I didn’t let the sealer sit for the 24+ hours, and I expected it to fail because of my own fault but 17k miles since application and leak FREE

Hey Chris, I recently purchased my grandpa's truck (99 ford ranger 3.0 v6) after he passed. I took it to the shop to get it checked out. I knew it was leaking oil so I asked them to find out where. They indicated it was the Cylinder Head Gasket that is leaking. I have had this with the covers but does this seem accurate?

I've used all but the one you used. Kseal lasted longest on my Chevy 6.0 Only about 3 months then again another 3 months and no effect after that.. Blue Devil lasted maybe 1 month. It was the second l used. The green lasted 2 months. I drove it about 15,000 more miles using all 3. Put it to rest at 250K mi. Hadn't it been for a blown hose and it overheating I'd still be driving it.

Bro I never really put too much stock or thought into these liquid head gasket repairs til back in 2013 my buddy called saying he threw the water pump in his 1998 Grand Cherokee 4x4…I spent a couple nights after work driving the 25 miles out to it in his work parking lot to swap it out, and when he fired it up it blew the damned coolant into my face. Told him he had a blown HG and he wanted a second opinion. We towed it back to a shop closer to home where they confirmed my findings. He then just signed the truck over to me (had a motor for it and wanted a 4x4 to kick around for fun). Tossed some Blue Devil into it for the 15 minute drive home…well…that damned Jeep drove 8 more years and 120k more miles (long range commutes, missing after I lifted it, etc)for me almost flawlessly!! I sold it a few months ago for a few hundred bucks and told the guy all this…he just texted me recently and said it still runs for his daughter as a daily driver to school (he has a motor for it as well, but hasn’t put it in cause it’s still running). It’s almost like a game show of “When will it die??” Not sure if it’s more due to the Jeep or the Blue Devil, but either way it shocked me!!

I have an 85 Toyota pickup 22r. The head was blown when I bought it, the dude apparently put K-seal in the coolant and when I flushed it, the overheating problems began to arise. I decided to try another bottle instead of tearing apart the head and its been over a year and its still running and driving fine today! Though now I can see some froth in the oil cap, so it's probably about time to do the real repair :(

Great video, Chris. Two questions please: When the original sealant stopped working, could you try another bottle and get another 10,000 miles out of it? Once you got the head off, could you have replaced the head gasket to make a permanent fix, or was the head block warping too great? Thanks!

I know this is a tangent but I have seen firsthand where on a diesel with exaust gas recirculation it had all signs of a bad head gasket. Blue exaust test loosing coolant when warmed up. Ended up being the egr valve with a bad gasket.

I used Bars Leaks on a 2001 Cadillac Deville, on the back it says for Northstar v-8,( I'm assuming it's got aluminum in it which helps it bind to the aluminum block head), the head gasket was destroyed because it was pumping out smoke, would go through all the coolant in about 10 minutes, use Bars Leaks per instructions, worked like a charm drove it for over a year, sold it and it's been running for five years now!!

Hi, great video! Which head sealer would you recommend for a 2007 Ford Fusion V6 with a small coolant leak into cylinder 1, only on cold start. No white smoke out exhaust. Repair would be $4,000. Mechanic used boro scope and took off upper intake manifold to diagnose blown head gasket after check engine light. Code p0301 misfire in cylinder 1. Coils and spark plugs checked out OK.

BEFORE YOU POUR THEM IN. ISOLATE your heater core from the system. These sealers clog heatercore and you will lose heat. Heatercore is like a small radiator with small passages. On prius, it's a pain to replace. $800 in labor.
