It does what it says
I given three of this product to mechanics with details as how to use it. The product sealed the leak into the engines crank case. The only problem with it is that it is a long and time consuming treatment process (up to 24hrs.). But considering the money saving it is worth the trial. May I remind you that water in the crank case is a very corrosive substance and when you gets blown gasket, you should fix that right away.
