steel seal head gasket sealer
I have a 1997 Toyota Tacoma 4x4 with a supercharger, over the years i got a small leak in my head gasket it was running rough every morning, start up. Also having a little white smoke every morning as well it would clear up after a couple of minutes. I knew i was going to have more problems down the road. I was told about this stuff Steel Seal . I felt like i have nothing to loose except to save $5,000 on a engine head gasket repair job which is expensive to me . Well i drain the radiator fluid rinse out the engine and radiator i placed Distilled water in the radiator placed two bottles of Steel Seal into it went for a drive about 10 miles drove about 30 minutes made sure i got up in the 3,000 rpm range then drove home and left the truck to cool. Next morning when i went to start up my truck wow" it was like a new engine, boy this stuff works i was so happy . How this stuff works is when the yellow fluid comes In contact with heat, from the piston combustion chamber and oxygen, it starts to gel thicken up right to the point were the leak is. Once the engine cools that area in the head gasket becomes a hard resin filler. I have herd people going 50 to 100,000 more miles from using this stuff After using it i change out my plugs ,oil, and replace the water, with radiator fluid your good to go. This stuff saved me a bundle . yes this tuff works Jim
