ATP AT-205 Re-Seal Stops Leaks, 8 Ounce Bottle

I am astonished at how quick the leak sealer has worked on my car. I have a BMW e92 at 150K miles with n54 engine which is known to leak from the sump pan gasket on older or high mileage cars. The oil leak seeps down on to the catalytic converter and causes a strong oil smell within the car, particularly when pulling up at lights etc. Also makes a mess of the under tray which covers underside of engine and gearbox., and if left, drips onto the ground under the car. The pan gasket is a Labour intensive and expensive replacement at a garage and a complete pain if tackled at home for skilled owners (special tools required). I was a bit sceptical about how well the sealant would work, but considered it worth a try before committing to gasket replacement. Within a few miles of running the car the leak has ceased completely and the burnt oil smell has gone. Works on any rubber based seals on just about any car, so if you have a leak do give it a try. I am a time served auto technician and absolutely endorse this product.

Great little product to seal a rubber seals in the engine like the head gasket and sump gasket. You need 2 bottles over 6 litres. They tell you to add to fresh oil to get best results. You also need to have driven 500miles, yes 500miles for it to work. Have heard some people say it stopped leaks whilst car was stationery but everyone got different results. My sump gasket was leaking. 3 months on with 2 bottles used as I have 7 litres of oil capacity and 1,000miles later it’s still leaking, However it’s now an improvement of around 75% and that’s good enough for me. It’s pricey here in the UK and around $6-8 in the US. Not guaranteed to work on all motors but give it time and don’t push the vehicle hard whilst it’s doing it’s job. It’s saved me around £500 parts and £300 labour. Also I would have to buy 7 litres of oil too. So it’s a huge saving for 75% working.

This product so far has cut down by at least 80% the oil leaks from my 300SE engine. It states you should drive for 5 hours before ( if it’s going to work ) checking for full effect, I have only driven approx 4 hours to date.

It actually works and it was competitively priced

THIS IS NOT MECHAICAL ADVICE! So I haven't really used this for its intended purpose. Came across these stop leak products in a Project Farm videos. Seeing how they work I'm nervous adding this type of product to oil but have found a different way of using it. Servicing tractors the manual fuel lift pumps hardly ever get used and quite often start leaking when you try to prime the filters, now tractor parts tend to equal EXPENSIVE. Several times I've found that using syringe with a thin needle to get a couple of ml of this directly onto (not into) the non-serviceable hidden seal has stopped the leak. I've also had good luck 50%+ using it directly on leaky hydraulic valves. This one bottle has so far saved me replacing around £3k worth of parts and there's probably 90% plus left

Good

Worked great on my car

I had a constant drip from a newly replaced front-end crankshaft oil seal and couldn't face tearing it all down, redoing the timing, etc., to replace it again so I gave this a go. Within 10 miles the very serious leak had stopped and I now have no sign of leakage anywhere. Magic stuff!

It is useful and powerful product which solve 100% your car issue. I strongly recommend it. Must buy worth product.

Alles ok

Normally I do not believe in products like this, in the past I was using one with Liquid and M... in name, but it did not work. I didn't want to disassemble steering rack in my old car, so I figured I could continue with the leak or roll a dice on this 40 eur thing. It just works :D The description says "will work in 5 hours" - yeah right. It turned out it did. I put it in, drove the car for around an hour and parked overnight. No leak! Previously it would leave an wet undercariage of a car, but now after 2 weeks driving - dry. I 100% recommend, if I will need something like this in a future I will definatelly use this one.

Tutto perfetto
