I developed a large head gasket leak in my Cadillac STS. I used your Dura-Seal Head Gasket Repair kit and within 1 hour, problem solved. Thank you!

I used your Head Gasket Repair. It saved my life. LOL Well, you kept my 03 Dodge Durango on the road. I had blown head gasket with tons of steam coming out of the tailpipe. The product worked wonders and saved my engine!!!! Thank You!!!!!

I have a 2001 Chrysler Sebring 2.7 V6, notorious for oil leak problems. I purchased a bottle of the Dura Seal Oil Stop Leak, after about 150 miles & approximately 3 days, as predicted on the directions, the leak was ENTIRELY gone! In addition & serendipitously, the oil light shut off, for the FIRST time in over a year & 10,000 miles! I reset the Check Engine light & passed CA State Emissions Inspection with no further leaks or oil or Check Engine Lights in over a year & additional 10,000 Miles. The stuff is truly amazing but not cheap...

I just had to write to you guys. I have a 1999 Ford pickup 150. The rear seal was leaking a quart of oil every 100 miles, and to change this seal I would have had to pull the motor, so I had nothing to lose to try your DuraSeal Oil Stop Leak. After 2 trips to town, I have ZERO leaks from the motor. Thanks for making such a good product! Oh, and I did try your Speed Wax, your right it really is better than any of the other waxes from the auto-stores... Thanks.

My 2003 Ford Ranger started losing coolant about a week ago, so I replaced the thermostat. That didn'tít work so I took it to a shop that told me I had a cracked block or blown head gasket and it would be $1800 to $2500 to fix it. Since I have 140,000 miles I knew that didn't make sense to me. I saw your Dura-Seal sealer on the web and gave it a try. I put it in a couple of days ago and it has amazed me how well it has worked. The truck quit losing coolant, runs 100% better and I think I may get another 100,000 miles out of it. Thanks!

I want to thank you for making products that really work. My Cadillac had a leaking rear main seal. My mechanic wanted 1200 bucks to fix it. Found your product on the web and gave it a try. Leak stop in 2 days of regular driving. Man that was over a month ago and so far so good. I'll tell everyone about you guys. Thank you.

I had coolant leaking into my engine oil on a 97 Corsica with 150,000 miles. Symptoms of a blown head gasket. Did a lot of research on the Internet to help me fix the problem and I feel I should also reply to others looking for help. I used dura-seal head and block sealant. I said my prayers and followed their instructions. IT WORKS. I saved my car, repairs would have been $1600 plus dollars and who knows what other problems would have arose from replacing a head gasket. One thing that wasn't mentioned in the instructions is that if coolant leaked into the engine, flush the engine also to get rid of the contaminated oil. I just change the oil before adding the sealant, ran the engine(as per instructions) with the sealant added. After I flushed the coolant system, I also drained the oil again and this time replaced the filter and used synthetic oil to better protect any internal parts that could have been damaged by coolant in the engine. My engine tapping noise went away and so far(3 months) have not lost any coolant and oil looks nice and clean. I feel very fortunate I used this product. I must say I was skeptical, but other user feed back help me try it, that's why I am adding this feedback.

Held great for 9 months so far on my Dura Max. Great product and the tech service was top notch...

I took a trip from Texas to South Carolina and by the time we arrived we started blowing oil from the exhaust, I thought we were done for. I ordered the duraseal oil stop leak and just added it to my oil and drove around for a few days. The smoke stopped and it's been fine ever snice, and all thanks to DuraSeal...best product ever!
Mary, S. Austin, TX.
I have a 99 Jeep Grand Cherokee 14000+miles. I had water in the oil, overheating and steam out of the exhaust. I used DuraSeal and was happy with the results. No more overheating or steam.
F.W. - Sternbock, IL.
1992 Mitsubishi Montero V6, at 138,000 miles I installed the duraseal product as directed. It worked for over 4 years until I had an accident and ruptured my radiator causing an overheat. Changed the radiator and called duraseal for another application and resealed the head! Cool stuff. I'd recommend it to anyone.
A. V. - Charles Towne, S.C.
I just used this duraseal in my 92 Mazda MX 3 for a blown head gasket. My symptoms included loss of coolant, water in oil, and excessive smoke from the exhaust. I used it and the smoke went away in about 5 minutes. No loss of coolant anymore and my engine is running a lot better, I guess it sealed up the compression loss at the head. I'm very happy with the results.

Could not believe that such a product existed and pondered the $2,200 (minimum) repair for the head gasket. Our mechanic took the time to flush out the radiator several times and added the DuraSeal sealer. They drove the car around a bit and noted that the engine did not overheat. I was scared driving home but can say that two months later after a lot of city driving in the summer the car drives well, shows no smoke, and the oil and radiator fluid levels have remained constant. The duraseal costs us about 160 bucks! But well worth it! I think my head gasket was damaged because there was plenty of smoke for a few minutes during the repair process but apparently things sealed well by time we finished the run cycles. The temperature needle goes up a ways when I idle for a while but always goes down. I should of had my thermostat changed a few years ago. Otherwise it maintains a low temperature setting since doing the duraseal repair. I was so discouraged in June when this all started but have been pleased that the car is functional. I even put duct tape over the rust spots and the car looks nice. This has been so far the best investment I made with any car.

I used this product about 4 years ago when I had steam coming out of the exhaust pipe. I used the Dura-Seal it worked great ever since then. But it's started to burn coolant again. I've ordered another application and already used it. This stuff is amazing! The coolant loss stopped again and now I've giving the car to my daughter for college transportation. Great product for the price. So far it's saved me over 4500 dollars by fixing my car twice!
Sally, M. Salt Lake City, UT.
I think this is an excellent product. I also think that it is reasonably priced compared to actually having my head gasket replaced. You do have to make sure that you follow the directions. I forgot to do the air-dry time and didn't take advantage of their free tech service and only got a partial seal. But I called the duraseal customer service people and they sent me out another application for free but I did have to pay the shipping on it. The second time I did follow the directions correctly and yes it did seal the head gasket leak very well. No more white smoke, no more coolant loss. Oh and that time i did call the their tech dept. and they went over the instructions in detail with me over the phone. I guess i should have done that the first time. I'd recommend their product to anyone.
A. R. Kirkwood, Ohio.
I never believe in stuff like this. I followed the directions exactly and it appears to be working fine.. The 2002 Cadillac with 55k on it was smoking a lot, then it stopped after driving for 15 minutes.!! It's been two moths so far. I'll update later...

I just wanted to say, you guys have a great oil stop leak product. I knew your radiator and cooling products to be the very best quality and quick to fix cooling system issues because I've actually used your DuraSeal block sealer on a leaking freeze plug on my Chevy Dura Max, but I never knew your oil products were so good until now. I am a proud owner of a 2001 Cadillac CTS and this past month it had suddenly developed a severe crankshaft seal leak during one of my drives to work. Oil loss was approximately 1 quart every 50 miles or so. (Like a faucet!) Well I decided to give your oil stop leak a shot. I didn't want to use the auto-store stuff because their products just thicken the oil so I did purchase your DuraSeal oil stop leak instead. It costs more than that bars and stp store-brands but since it's not an oil thickener I figured it was worth it. I purchased the two bottle special and put the stop leak bottles in the engine and drove to work the next day. By the time I arrived back home later that day, it had completely stopped leaking! No more visible loss!!!! I want to commend you on a superior and outstanding product! As with all your DuraSeal branded products it has exceeded my expectations and saved me 3,000 dollars for a rebuild! Next I'm going to try your automotive waxes. Keep up the good work...

I have never responded to any kind of testimonial before but I had to this time. I am very skeptical when it comes to stop leak products but my 1999 Nissan 6 cylinder has 175,000 miles on it and has had the engine rebuilt. It was leaking oil so bad my wife wouldn't let me park in the garage or even on the driveway! My mechanic didn't want to tear the engine down again so He recommended your DuraSeal Oil Stop Leak. Since it was so highly recommended I bought it. I thought, what the heck? After I change the oil and added your engine oil stop leak, it's been three months, I don't see any oil leaks at all anymore.

I've been semi-trucking for over 22 years. Over the years I've used a variety of products, but none have worked as well as your DuraSeal head gasket sealer. For instance, last year the head gasket on my Kensworth diesel engine started leaking coolant in the oil, that's real bad because it costs around 12,000 dollars to replace it on a semi-truck. With the economy the way it is, I couldn't afford to do that! I used your duraseal and I was amazed. It simply worked!!! It's doing great and I'm still driving my semi-truck on a daily basis. I just wish my trailer was more full, I'd be making more money... But seriously, your product really helped me a lot... Thanks
Kenny, M. Clark, Texas
Last week while on vacation my intake manifold gasket on my Chevy Tahoe started leaking faster than we could pour it back in. We added a bottle of your DuraSeal sealer for the intake gasket and it stopped the leak in only a matter of minutes, the leak stopped and we traveled home safely. Great product. And a personal thanks to Chris in your tech dept. It was nice being able to have him go over the instructions with me over the phone, I'm not a mechanic but luckily He is...
M. W. - Gorbit, Texas
Our sons car started leaking antifreeze through the headgasket into a cylinder. We put in a bottle of your Dura-Seal head gasket sealer. It's been six months and still no leaks. Thanks guys.
C. S. Ammansland, Pennsylvania
When changing the oil in my truck, my neighbor came over and asked if I was a mechanic. I assured him that I wasn't. He told me his head gasket leaking from between the head and block. He couldn't afford to take the car to the shop and have it repaired. I told him about your duraseal product and he bought some for it. We performed the repair together and actually got the head gasket sealed up that day. We could actually see the external coolant leak slowly stop. My neighbor thanked me profusely and walked away smiling. But I wanted to actually take the time to thank you guys...
Paul, B. - Jackson, TN.
My 1999 Chevy van that I use every day has over 175,000 miles on it. The head gasket split last month and I started getting oil in the coolant and white steam from the tailpipe. I added your DuraSeal. Within less than five minutes the white smoke stopped. By the time I finished the run-cycles (per your instructions) the engine temps came back down and stayed in the middle and no more coolant loss! Your DuraSeal has bought me enough time to finish my roofing jobs on time without putting me into downtime. After 25 years in the auto / truck and field repair business, I wish I would have found these products long before now, because your sealers actually do what they say.
