Review on 💙 Blue Magic 1116 Liquid Glass Metallic Seal-Up: Professional-Grade 22.8 oz. Solution by Pete Brown

I had a horrible leak in the engine block (losing about a gallon an hour and smoke like crazy from the tailpipe) and I offered a $4,000 engine swap. I tried this and a "less generic" product to fix my truck. The K-Seal product didn't seem to seal it. I poured a bottle of this and it seems to have helped. Around the 18 minute mark of the 20 minute bake time I think it blocked my thermostat and the motor started to get dangerously hot as if the thermostat wouldn't open so keep an eye on it and have a spare thermostat handy if you do use product. By following the instructions and replacing the thermostat after observing this behavior, this 4.7L Tundra engine is back in service with over 300,000 miles.
