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.

Excellent product. This does work and is great at swelling and sealing.

Good stuff, sorted my oil leak quite quickly.

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.

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.

It actually works and it was competitively priced

Seems to have stoped the leak. Very happy. 👍

My Mk VI Fiesta has now done more than 100k miles. So it's kind of a no-brainer to do as many of the cheap things that would keep it running longer. Some of the slow oil leaks that bleed out around the lower engine case got my attention so I read up and found this. In contrast to replacing actual seals, this is a damn site cheaper - if it actually works. Thing is I can't really tell if it has. I've never had that bad of a leak so if anything I've maybe just reconditioned the seals a bit. My best advice is; if you get an oil patch under your car and the garage can't pin down where it's coming from or how bad - this might well be worth a shot. If it's just very slow bleed around the engine case but you don't see any evidence of drips, I'd leave it.

De momento no echa humo,se ve que hizo su función en los resellos,aunque tengo que cambiarlos,por después de 33 años están resecos. Un apaño temporal,sin dudarlo lo volveré a comprar hasta que solucione el problema.

used half the bottle as that works for my just over 4L tank - stopped the leak in my 95 saab aero (2003) - would have cost me $3500 to fix a stupid $10 seal between the head and transmission otherwise. seems like I will be able to pass inspection now!

Alles ok

I highly recommend it. Works well to stop leakage from rear end crank shaft seal. Pour it once and leak is gone. Worked well on any other rubber parts like protective rubber boots and squeeky steering wheel bottom boot near the pedals inside the cabin. Can pour into a spray bottle and spray the boots. Rejuvenates rubber on instant contact, won't damage or harm rubber.

Si regenera los sellos, es mejor que los selladores q hacen todo mas espeso
