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.

So far so good! Used on my Audi A6 2012 3.0t last week and the car has not been losing any coolant. The white smoke has drastically reduced and the car is now running more smoothly! As long as you follow the instructions correctly, this has to work! So far a 5/5 product!

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.

This stuff works about 75% of the time and will usually provide a permanent fix. It worked for me on a small block chevy v8 that had a very small leak and I was seeing oil on the inside of the radiator cap. I've seen youtube videos of people who have used this stuff and the engine is still going strong after tens of thousands of miles.An important thing to note: head gaskets usually blow when the car is overheated. The first overheating event is usually the cause of the head gasket failure, and it's often due to running out of coolant because of a leak in a hose or the radiator, or an electric fan failure. The head gasket blows, then subsequent overheating is caused by the blown head gasket. If you know what caused the original overheating and fix it, then this product, if it works initially, will likely give you a fix that is permanent. If you try this stuff and it works and you love the car and you do not know what caused the car to overheat in the first place, it isn't a bad idea to replace the radiator. Now that you don't have to pay for a head gasket, the rad replacement cost is minimal.You're generally going to know within an hour if this stuff worked. Just follow the directions on the bottle. If it doesn't work the first time, I would drain the rad, add distilled water and repeat the process one more time. If the product does work, I would drain and refill all the coolant to get the barrs out. They say you do not have to, but I have seen a few reports of the thermostat or heater core getting clogged if you leave it in.Again, in about 25% of cases, this stuff will not work. But if it does work, it's like a miracle in a bottle.
