I f you have a better idea....please share it with me.my dads gone now,and i promised him i'd take care of his old truck, he bought it new and left it with me, thanks for any help bob s
As far as removing the rusty old bolts, I've found that Gibbs Brand lubricant works awesome. I use it for so much more than just rust bolts. Soak them every day for a few days if you're not in a hurry. When you're ready to take them off, hopefully they will come out, but if not, add some heat with a torch.
Ideally you'll want to avoid head but you can use it as a last resort. Heat can warp or damage the head and the gasket sealing surface.
I learned about Gibbs on the "Powerblock" on sunday mornings on spike TV. They have all kinds of great products and tips on there. The stuff really is great and I use it all over the house. It is by far the best penetrating oil I've ever used. It works its way into everything!
