Blue devil head gasket sealer
I have a 4.7 that heated up on me today. Now after it heated up I stopped it ASAP, I let I cool down and was able to move it to a near by friends house. Now after I let it cool down a little more I added so antifreeze and noticed it was leaking out out my muffler .. A friend of mine said to use blue devil And that it would fix Has anyone use this before and work. I would really like some input if it works.
