No more white exhaust smoke!
As a 35 year mechanic, I'm not keen on 'mechanic in cans' treatments, usually a mechanical repair is required, i.e. leaking cylinder head gasket, thus new cylinder head gasket, and the 10 ++ hours of labor and parts. My 2005 Ranger 4.0 V6, 385k mileage was diagnosed as 'failed' head gaskets, water/oil into the radiator coolant, white smoke out tailpipe from burning in the combustion cylinders. With nothing to lose and extra time and expense saved, a can of Copper Block Seal was installed. After about 5 hours of running the smoke diminished, and coolant reservoir quit running low. Have placed 500 miles of highway driving and this 'patch' repair is holding up. Mixed with coolant w/o draining the radiator, Would highly recommend this as a 'first' repair attempt. Saved me $2.5 K in unnecessary repair expenses.

Works well, stopped a minor leak in 2002 vortec v6
UPDATE: Not a permanent fix IF you try and flush the coolant system. Make sure you have your antifreeze added before you add this and never touch it again. I've used this stuff twice in 20 years and both time it worked great. The first was in a 1998 grand cherokee that was driven across town with low coolant resulting in a blown head gasket or cracked cylinder head. The second a 2002 S10 v6 that ran great but consumed a half gallon of coolant every few days. In both cases I added the full bottle and drove the car. In the case of the S10 it took a couple days driving to work but it's been a month now and no leaks. Saved me a ton of work replacing the head gasket and/or cylinder head(s).

Does the job
Did what it said and stopped a block leak in a 2007 Mazda 3. I only needed to use half the container, so I still have some left for another leak down the line. Not much else to say.
