I tried your sealer in my 2004 Cadillac with the Northstar engine 2 weeks ago. The car is in perfect shape, inside and out except for that dam head gasket. I should know better because this is my fourth Northstar. I could only drive about 7 miles before the engine would overheat. After finishing the repair its been doing fine and running like a charm. This product saved this car from the junkyard cause with a blown head it would have been worthless regardless how nice it looks. Thanks guys!

I would just like to thank you for making a great product. I own a 1999 Plymouth Grand Voyager that has been over heating for the last month or so and finally today was the breaking point when the temperature gauge would not return to normal. Just like many other people in this situation we do not have the money to replace a blown head gasket. After doing some searching and researching I came across your product on the internets. Needless to say I was a little skeptical about your product however, that has now changed. I followed the instructions on the bottle of and also replaced the thermostat. I allowed the van to idle for 15 mins or more and I did not see a change. So I decided to take it for a drive and instantly I could tell the difference; then finally after fighting with the heat for weeks now it finally worked. I am going to drive it once again tomorrow to make sure everything is fine before I let my wife drive it but, I am very thankful once again.

I installed your turbo diesel head gasket kit in my Chevrolet 2500 diesel engine because I had coolant leaking into the cylinders. It appears to have stopped the leak. I topped off the cooling system with anti-freeze, but I am wondering if I need to put more Head Gasket Fix in the system when it comes time to replace the coolant. Thanks!

My daughter's 1998 Dodge Intrepid with 129,000 miles on it was having a problem overheating. We took it to a mechanic and was told the radiator needed replacement, as well as the water pump, hoses, but the head gaskets seemed ok. We had the repairs done, to the tune of $1600.00 and two months later the car was overheating again. After two trips to two seperate mechanics we were told the head gasket needed replacing. Well, this car is definetly not worth the price of repair, so after some long research, decided to try your Head Gasket Fix. I had to put the product in the upper radiator hose as this car has no radiator cap, and only about 3/4 of the bottle would go in. I followed the directions and the car's performance improved as well as the overheating problem seems to be solved. It has been only a few days, but everything seems fine so far. I'll comment later after a longer term. Great product!

My 2003 Land Rover smelled like antifreeze and a dealer I took it to said either head gasket replacement around 3000.00 or he could try your Titan Sealer. He did and that was 8 months ago. I am very satisfied and I am going to be ordering your oil stop leak soon. Thanks a lot!

I bought your Head Gasket Fix my 1997 Cadillac Deville with a 4.6L Northstar engine with 111,000+ miles on it. To make a long story short, it worked. The engine was stuttering or missing 15 seconds on a cold start up or 15 seconds after a warmed up stoppage of the engine and restart. I suspected that antifreeze/coolant was getting into the #1 cylinder due to a defect in the cylinder head gasket. The cylinder head gasket is very difficult to replace on this engine as the transmission has to be removed first. Thanks for such great product.

I experienced a major intake gasket failure on my Chevy 350 causing the entire contents of the cooling system to empty into the oil pan during a short 5 mile drive to work. The failure was so extensive that the slurry found its way into the cylinders and air cleaner housing as well. Not looking forward to spending a Saturday tearing down the top half of my motor, I instead decided to try your seler. I visited your website to become familiar with your entire product line and choose the chevy 8 cylinder kit for this situation. To be honest, I didn't have high expectations for success due to the seemingly extreme condition I was using the product for. I am very happy to report that a single treatment with the product has sealed the failed areas. The operating temperature is normal, after 3 oil changes the oil is staying clean, and I have not lost any coolant. My advice to anybody considering using your product, is, don't let the $130 price scare you into using a lesser option. Although every situation is unique, this product worked for this situation better than I expected.

I used your sealer not expecting anything. My mechanic told me that I had an internal and external head gasket leak on my 1996 Toyota 4 Runner and advised me to junk the vehicle. Within 45 minutes of adding your product, the steam out of my tailpipe stopped and the engine compression returned. I am just amazed and so is my mechanic.

Thank you for saving my automotive life. Last week I had both of my vehicles in need of your products. My 1991 Toyota Previa van lost its head gasket, antifreeze in the oil and smoking like crazy. I used your head gasket sealer and 60 minutes later I noticed a huge difference. It has been a week and my oil looks like oil and my antifreeze level is perfect and she runs like a champ. My second car is a 2005 Chrysler van which sprung a bad radiator leak. I used your radiator and block sealer and it has no more leak. Thank’s! You saved me from many thousands in repairs or a new car payment.

I just wanted to say that I am very impressed with your head gasket sealer. I had coolant leaking out of my head gasket and poured your sealer in my radiator and went through the repair processr and the leaked stopped within about 60 minutes after the thermostat opened. I was a bit leary of using a stop leak for fear of clogging up my heater or radiator but so far I have no problem with that. Your sealer appears to have saved me over a grand in repair cost.”

Thank you for taking the time to talk to me about the head gasket leak in my '2005 chevy v6 and for sending the email on how to eliminate any air bubbles in my cooling system. I installed the head gasket sealer into the radiator per instructions and finished the repair about 2 hours later. The car no longer puffs steam out of the tail pipe, the “low coolant” light does not come on any more and there is no longer a mis-fire. Thanks to your stuff, my van runs great and you saved my ride and saved me a huge repair bill for new head gaskets.

Just wanted to put in my testimonial after reading countless others on yourproducts. I own a 2002 caddy with the northstar engine, and after having to put AT LEAST a third of a bottle of coolant in EVERY day, it was diagnosed as having either a head gasket leak or a head gasket that was completely blown. 20 ppm of hydrocarbons in the vapor from your coolant tank and you have a bad head gasket, mine read 191! After putting your product in, I haven't had to top off my coolant one single time!

I was having an antifreeze leak on my honda civic with 158K miles on it, and it was determined that the problem was the head gasket. My repair shop said that if they replaced the head gasket, the engine would burn oil, so they wanted to replace the engine for $3000. I put your honda repair kit in and the car has not leaked any antifreeze in more than 5,000 miles. I'm very pleased, to say the least!

I am writing to tell you of my good experience with your titan head sealer. I am pretty skeptical when it comes to additives but I have an 2006 subaru with the 4 cylinder and over a year ago the head gasket started leaking water into cylinder #3, drip, sizzle, drip, sizzle, and blew out water when the spark plug was removed. I was quoted a figure of $1800 to fix it. It has 157,000 miles on it so when I saw your sealer was actually made for my engine I was excited. Well I was ready to sell this thing to a junkyard until I put your stuff in it and it worked! I am not in the habit of endorsing products but this stuff really works!

I have the same truck and had the same problem. Did alot of research on the different oil stop leak brands out there and found the Titan oil stop leak. They were the only company to actually have a oil stop leak kit specially made for the semi trucks. Their kit included 6 small 8oz. bottles of a special non thickening stop leak formula very different from any of the other brands like Lucas or Bars.It costs around 200 bucks but it stopped all my oil leaks and it been almost 3 years now. I know I spent more then that just on replacing lost oil for a few months. What it boils down to is the other brands like Lucas and Bars just make your oil thicker which slows the leak down. That really doesn’t fix anything. The Titan stuff is mostly silicone and when you add it to your oil the oil seals absorb it and grow back to their original size. That actual stops the leak the right way.No increase in compression and no clogs. It was worth every penny.

I would like to inform you of the success I have had with your head gasket sealer. I have a Land Rover and a few weeks ago it started overheating losing coolant. I took the car to a garage and they did a hydro carbon test. It failed! They gave me a quote of $4200.00 to replace the gaskets. I can't afford that so I searched the Internet for other solutions and discovered your Titan Head Gasket Sealer. I followed the instructions, added the magic potion to the cooling system and did the 15 minute run cycles and it stopped overheating by the time I was done. I now have over 1,000 miles on it, and it still looks like your seal is holding! Good stuff. Thanks.

Titan Engine Oil Stop Leak WORKED!!!I own a 2006 Nissan Frontier, my vehicle was having major oil leak issues. I did my homework and all the oil stop leak products like bars, lucas and stp claim to do the same thing. They make your oil thicker to slow the leak. That’s a really stupid way of trying to fix a leak. The reason I chose titan oil stop leak over the other products is because their stop leak is thin like water and guaranteed not to thicken the engine oil. I mean if the seals and gasket are already stressed out why on earth would I want to thicken the oil land increase the oil compression with those other products. That would cause more oil leaks or at least put more stress on the seals. So I ordered the titan oil sealer and used it. In about 2 days the oil leak at the rear main seal stopped leaking. About a day later the oil leaks from the valve covers stopped. My vehicle has over 180,000 miles and I'm still driving leak free. I waited six months to give a full review.

Just used the Titan oil stop leak product last weekend. It worked. The leak stopped after few hours...hoping it will last long enough for me to save for a re-manufactured/re-build engine next year. This product will surely work for those instances where seals and gaskets are dried up or shrank due to wear and tear. I picked the titan oil stop leak because it was the only non-thickening formula I could find. Lucas oil stop leak is so thick it won’t even pour out of the bottle. I don’t want that in my truck. I think you the Titan product is a lot more advanced than any of the other brands out there. It’s not cheap but hey if it saved me from paying 1800 bucks to replace the rear main seal, I say go for it.

The best head gasket sealer I found was titan head gasket sealer… All the other ones use that water glass in their sealers. Water glass won’t work on aluminum engines… and titan is the only one that uses a polymer formula. It worked for me. Better use it soon, the longer you wait the worse the head gasket will get.

I tried bars and blue devil, the only one that worked on my Audi is Titan… They make it for every engine out here including yours. It’s called Titan Head Gasket Sealer, it’s not water glass like Bars Sealer so it can’t hurt your engine. I used itin my 98 Audi a4 2.8 Quattro a few years ago cause even back in 98 the heads on my Quattro were aluminum and their stuff is made for that… They use some special polymer instead of water glass or silicate like theother sealers out there.

First thing, don’t even think about trying Blue Devil!!!! I tried it in my BMW x5 2004 and it completely clogged my heater core. They say it works on any car but what they don’t tell you is silicate based also called water glass sealers (which blue devil is) don’t work on aluminum! Both my BMW and your Forester have all aluminum engines so definitely don’t use Blue Devil. Not only will it not work on aluminum engines it actually pulls metal off when it starts to crack away (which it does almost as soon as it cures). The only head gasket sealer out there that is actually made to work with aluminum is Titan Head Gasket Sealer… It’s made of a polymer instead of water glass so it can stick to thealuminum and flex with it. Hi tech stuff considering after I checked around all the other sealers including Bars, Steel Seal, Thermagasket (which is the worst of the worst), and of courseBlue Devil all still use silicate water glass in their sealers. Anyway, I the Titan sealer it in my BMW and got the head gasket fixed in about 4 hours of running the engine with the Titan sealer in it. That was about 3 years ago and it’s still holding. What really makes me laugh is seeing how much Blue Devil promotes their sealer on the internet and its garbage!!!

I’ve been a certified mechanic about 32 years now and I’m not a big fan of any additive but your right… If you are going to use a head gasket sealer the best one is the titan sealer.Based on it’s formulation I recommended titan to a few people because their car or truck really wasn’t worth putting a lot of money into and it worked fine.One of them had a 96 pontiac sunfire 4 cylinder (not the best car in the first place BUT) it was her only car and was blowing water out of the tailpipe. I actually got the water to stoppouring out of the pipe with the titan stuff… So if your needing to get your forester fixed on a budget I say go for it.

I had the same issue in my 05 Kenworth T300 water in the oil, white smoke and overheating. The Titan sealer got it up and running. I found out that if you have fluids mixing (oil/water or water/oil) the Ttian Semi-Truck Head Gasket Sealer Kit (comes with 4 bottles of sealer each bottle was 32oz. and the kit can treat up to 25 gallon systems) will seal the coolant-side of the problem but you will also need the Titan Semi-Truck Oil Stop Leak Kit to take care of the oil-side seals on the head gasket. Both kits will come with instructions but just remember to always to the coolant-side repair first with the head gasket sealer then you just addthe Oil Stop Leak bottles (there will be six 8oz. bottles in the semi-truckoil kit) to the new oil…Both kits are going to run you around 380 - 400 bucks but it got my truckfixed for a hell of a lot less then tearing the engine down.
