My 88 f250 351w has a blown head gasket. I was thinking of using some blue devil head gasket sealer. I know it will not last forever but i need the truck now. I can fix it right later. What are your opinions of this stuff? Should i use it?

 

You actually have a better than 50/50 chance of good results...be sure to follow the directions to the letter. Make plans to replace for any real long term use of the motor, good luck
