just pulled of my manifolds in order to install a set of headers. about 3 weeks before the job, i started shooting all the bolt heads with PB Blaster. i wanted to soak them good because i have read so many posts about guys breaking and striping bolts when installing headers. bottom line is this stuff worked great. every bolt came right out - once i hade all the junk out of the way (AC bracket, heat shields…) i pulled each manifold off in about 10 minutes. i have used other penetrating fluids, but this stuff really eats at the corrosion like nothing else i have seen…
