Bar's Leaks HG-1 HEAD SEAL Blown Head Gasket Repair

Listen up everyone! Stop scrolling and read this!!! My trailblazer was acting like I had a blown head gasket or cracked head! Its a 2003 with well over 260k miles on her! Other than this shes done me so well. One morning I was on my way to the doctor's. I looked down at my gauges and my oil bottomed out the pressure in it. I was blowing white smoke out the back and then it stalled so I pulled over sat there a minute restarted it and the oil gauge went up so I got to the nearest store checked my oil my oil was low so I put oil in it It was fine for a little bit then it kept doing the same thing. So I went and got an opinion on what could be wrong and they had told me cracked head or head gaskets. I don't have $7,000 to pay to get it fixed when my truck is worth at top end $3,000. So I decided to do research and I came across this b a r s all the reviews I read we're good sorry I figured out I'll buy it give it a try. I got this in the mail read the directions did it to a t It took about three running cycles and my oil's been keeping pressure I haven't had any white smoke blowing out the back. This is the best stuff I have ever purchased for in my truck that actually worked Do not hesitate to buy this trust me it'll save you thousands of dollars whoever came up with this product I hope they're making bank because they're saving me bank.

It really works!My 2GR-FE engine was overheating after about ten minutes from cold start, and I was losing coolant constantly. A combustion?leak test confirmed a blown head gasket. Repairing it would require pulling the engine—far too expensive for my car—so I tried this as a last resort, and the results have been fantastic. The coolant temperature returned to normal, and I’ve driven it for about a month with no issues. I still see a bit of coolant loss, but I’m not complaining—at least my car is back on the road!I'll update after one year or 2 years. I'll be grateful even if it can only last one year.

If you do some research and check out various automotive forums everyone almost unanimously despises these products treating them like snake oil. If you plan on replacing your head gasket then do not use a chemical sealer in the mean time. If, like me, you just want a little more time out of a dying beater then go for it.I have a 98 F250 (RWD) with a wimpy 4.6 Triton. It has ~246,000 miles on it. Paid $2,000 for it several years ago. Recently it started overheating and overflowing the coolant reservoir. There was no oil in the coolant or coolant in the oil. Ordered a $40 block tester off Amazon and the blue fluid turned yellow indicating a bad head gasket. I called a local mechanic and he said it would be $3,000 to fix it but he wouldn't touch it because of the overhead cams. He recommended Blue Devil. After some research I decided the procedure for Blue Devil was too bothersome as it required a coolant flush and being poured slowly into the radiator. The only easy way to add coolant to my truck is through the coolant reservoir.The instructions for this sealer are simple and easy to follow. I dumped a whole bottle in the coolant reservoir and thermal cycled the engine two or three times with the heater on blast before taking it for a drive. The temperature gauge stabilized about 1/3 of the way up from the cold indicator and stayed there. No more coolant overflow.I have no idea how long it'll last. I'll be thrilled if I can get another year or two out of it while saving for a replacement. If it starts overheating again I'll do my best to update this review.

UPDATE: No more than two weeks after writing the review below, I got a check engine light with a Cylinder 1 Misfire on the OBD. I cleared it, and a few days later it came back on. This pattern repeated for about two weeks, and it became clear that it was time to let my baby go. I think my 100 mile drive to San Diego and back was what put the final nail in the coffin.So in summery, yes, this stuff works temporarily, especially if your car hasn't been overheating and you're driving less than 30 miles at a time. It probably would hold indefinitely if you're only commuting and not transporting a heavy load. It really is a finger-in-the-dike solution, and it won't hold for long under stress. It got me through two months which was long enough for me to drive down memory lane and say goodbye to my old truck and replace her with her baby sister, just like that episode of the Wonder Years when Jack Arnold (the dad) has to replace the family car. I wasn't disappointed by the outcome but took a star off my original score, just so my review is not any more misleading than it may have been.Is it worth buying? It was for me, but if you're less sentimental and you'd rather tare the bandage off than peal it, I would go directly to replacing a high mileage car or the head gasket. Good luck!Please read on for the original review:ORIGINAL: Crossing my fingers as I write this, but it seems to have done the trick! I took my 2005 Tacoma into a local auto garage after the first time the Check Engine Light came on in late May. Mechanic said it was my thermostat, so he replaced the part, and I was on my way $400 later.Check engine light came back on June 20th, and by this time I had purchased an OBD II bluetooth scanner and Torque Pro for my Android device, as I felt powerless with my last experience. It showed a cylinder 1 misfire, and figured I needed new spark plugs so I went on Amazon to purchase new spark plugs, a spark plug wrench socket, anti cease compound and a torque wrench to do the repair myself (it was kinda fun!). I cleared the check engine light, and drove normal until July 6ish, when the check engine light came back on with the dreaded cylinder 1 misfire. From then on, I kept clearing the light and checking to see how long it took for it to come back on; it seemed to happen every 5 or so days and always when the engine was cold, and I was speeding up from 0 to 45 mph, as I live right off a busy street.Took the truck to the dealership on August 1st for a diagnosis, and they told me that I had a minor blown head gasket, which was leaking coolant into my cylinder 1 causing the misfire when the engine was cold. They can tell because, they checked the spark plug for wetness after leaving the engine off over night. As the engine heats up, the misfires stops because the gasket expands and creates a seal. They used the scare tactic to tell me that I will need a new gasket or I would need to sell the truck within a few weeks because the engine will soon start over heating, leaving me stranded on the side of the road. The repair would cost $2500, which include the gasket inspection of the head for cracks, machining the head, and obviously reassembly. Check out the photo attached the recommendation.I got super depressed that I would have to give my baby up soon, as she and I have gone through so much together, so I started to research the problem and came across this Head Seal and a similar product from another brand. After watching a few testimonials on YouTube, I decided to give it a shot. Being a total beginner in auto mechanics, I didn't understand how to drain the coolant properly, so I made a mess, but got the Head Seal liquid in and ran the engine as instructed on August 4th.I kept my eye on my OBD with my android tablet almost every day, and found a cylinder 1 misfire "pending" in the app five days later on August 9th. My check engine light came back on the next day on August 10th, and I got depressed again. I cleared it and kept driving, as I started to shop for a new truck. Well, it's September 6th almost a month since the last misfire, and there hasn't been a new one. I keep the tablet in the truck most of the time to run diagnostics, and still nothing.Here's my theory: Because I only had a slight leak, the nano particles took a few heating and cooling cycles to really get in the cracks and cure into place. Therefore, it's a slow process, especially for an intermittent leak like mine. I try not to rev my engine over 2500 rpms, and drive slow while it heats, which probably helps too.So far so good! I keep my tablet in the car to keep an eye on the thermometer as well, and the coolant stays at about 88 degrees Celsius when driving on the freeway, which is perfect. As soon as I see an uptick of one or two degrees, I'll flush my coolant. I've gone on several 100+ mile trips also in the last month, and it's holding up.It's been a roller coaster ride (not the product, but my experience with my truck) but I'm glad things are stable. Will update if anything pops up in the next few weeks, but it looks like this seriously saved me $2460, at least for the time being. Knock on wood. If you're having these issues, good luck, and may the force be with you!
