AT-205 Seal Leak Stopper 8 Ounce - 2 Pack

This product is working great so far. I had a decent leak in my vehicle, and the day after utilizing this product, after driving for a little over an hour and parking over night, I saw a significant decrease in the amount of the leak. Over a period of 3 days, the leak had decreased to only a few spots. Today, I drove for a straight hour to circulate the product some more; hopefully, I will wake up in the morning and see no leak.

Normally I am not one for dumping mystery oils into an engine to fix problems. However, ran into an oil leak issue on a 15 year old front wheel drive vehicle where a tear down to replace a leaking gasket would have been cost prohibitive. The leak in this case was from an engine oil pan gasket (which was actually not a gasket at all, just RTV). For this particular vehicle the engine oil pan is also has the transmission mounted to it, so getting all that apart would've been a total nightmare. After some thinking, looked into various products and gave this one a try. Sealed up the leak after about 3 hours of driving. Can't comment yet on longevity but so far so good.

03 suburban 5.3 had a leak ( I'd classify it as a smallish leak. used 2 and no more leak!. Scotty Kilmer on YT showed it to me

I have used this product many times. It does in deed work. Obviously, it’s not a permanent fix but definitely helps to stop those leaks. Wish the price point was a little better , reason for the 4 stars

I have a 99 Chevy astro with 111,000 miles. I developed a slow rear main seal leak and front crank seal leak. I wasn’t willing to drop the pan and pull the whole front end apart to get to these parts. I purchased this product and after 1000 miles. I do not have a leak. This product is worth every Penny if you have a GM vehicle with oil leaks this is a must, now if your car is puking oil. Don’t think this will fix it. You need a slow leak. Nothing major, this is now going in all my cars to prevent major repairs in the future,This even helps harden valve seals. Just a heads up.

This stuff works. It stopped a leak between the engine and transmission that was going to cost me 1000.On 2015 Honda Accord

Worked on my vehicle but didn't do jack for my wifes car after Valvoline Restore n Protect caused both rear main seals to leak. Because it didn't work on my wifes car I wasted HER money. I hate my life
