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

Did exactly what it said, it stopped the engine oil leak

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.

My car was losing oil like crazy. I cange the oil and mixed the product with the new oil. Works like a charm since then, i check the oil every week and I’m impressed with the results.

The fast and effective repair done to my car engine oil leakage . I pray it last long . Good value for the amount spent.

very wary of using these thing in my car engine but was told I had a small oil leak some where in the engine and could not find it used this stuff and no oil leak also seems to have made engine quieter

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!

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.

Good
