AT-205 ATP Re-Seal Leak Stopper 8 Ounce - 4 Pack

My husband ordered this for his truck but, he’s a big believer that this helps quite a bit. Price is awesome compared to auto shops.

slowed the leaks in my190,000 truck

Excellent product 👌

it's great sruff , been using it for many year , very good results

Expensive and seems to work.

I heard about this from a youtube car guy and decided to try it on my wife's Acadia that had a leak at the timing chain cover. Added a bottle of this to the high mileage oil (Mobil 1 synthetic high mileage) and no more leak! Took a couple of weeks but one day no more oil on the ground. Amazing stuff! Also put it into my Camry that has over 200K as a preventative and so far no issues. I add one bottle with every oil change now as insurance.

Great product

I have known about this product for quite a while now. I recently bought a used car that was overall good shape, but had some oil leaks. After watching a review on Project Farm, I used this in the car (as directed) and after a few miles, my garage floor is dry! My vertical bandsaw had a gearbox leak. Problem solved. If you have an ugly gasket job like a rear main or front seal, try this first. As always, read the directions before use.

Works great. Had a control valve leaking on my skid steer, added 2 bottles and used it for 2 hrs - leaked stopped ! Definitely recommend

I've never used any other stop-leak product because they all just seem to be thick juice. What made me try this was reading tons of reviews that mentioned it is specifically targeted towards rejuvenating seals. I've only ever used it for small, quarter-sized leaks, and it's worked to seal them every time. The first was with a power steering leak that I couldn't find the source of. The cramped engine bay made it very difficult so after reading a ton of reviews, I decided to give AT-205 a shot. A week later, the leak stopped. I checked the power steering reservoir every week for a couple of months and it stayed at the same level. Not bad. The second was with an oil leak that was a bit larger. I had already spent time replacing various seals (oil filter housing, oil cooler, valve covers, spark plug wells), but there was still one leak I could not find the source of. I decided to give this a shot again and within a couple of days, the car was leak-free. Quite an achievement on an older German car. Although I prefer going for a proper fix first and replacing seals/hoses/etc., this is definitely helpful when you're at your wits' end

This is an update after 3 months. It does work on oil leaks at the lower part of the engine but not on valve cover gaskets. It is still worth using for oil leaks and change the VC gasket. I was a little skeptical like all others. I figure there is no harm to try before I change all the gaskets and seals to fix the oil leaks. After all it is a big job to do. I was having 2 puddles of oil underneath each of both of my cars. I added a bottle in both my 07 GTI and Audi A3, both with the same engine. After 100km I started seeing some small result. I did take out the under pad of my car and clean before I added the AT205. I cleaned the under pad again at 200km and put a piece of cardboard under the car to make sure I can see any oil leaks. Yes, it is still leaking a drop or two on the under pad but I don't see anything on cardboard after 300km. I guess it does work. I'll keep driving till my next oil change and maybe an update later.

This item really works on small dried up rubber, cork, etc. seals. Old seals on old cars are sometimes not worth repairing. So the cheapest way to find out how bad the leak is, may be to try a good sealer, with a good track record. If it slows it down or stops, you win. If it doesn't, then you know a chemical will not work, and a physical repair is necessary. Also, this product will not effect the viscosity of the oil you are treating. Tried it on a 10 year old VW cc 2.0T and the oil smell from the a small seeping valve cover gasket is gone. Now I only use half a bottle (4 oz.) in every oil change with Euro 5w40 and has not returned in 2 years.

It stopped a slow leak of engine oil by the timing belt/cover (my Honda dealer said it had a small leak). This stuff is magic as it also stopped a leak of the power steering fluid in the rack and pinion assembly. I saw the Youtube video of Scotty Kilmer on this fluid and thus tried it. Definitely worth trying if you have a leak (in one of its recommended uses)!
