Bob,

You might try a product called PB Blaster it is the best penetrating oil that I have ever used. I never used to believe in that kinda stuff but when I was putting the Banks power system on my 95 F 350 was when I found out about it.

The truck has a 460 gas motor and they are known for having extreme exhaust temps which work harden the exhaust manifold bolts. After breaking off two of them I was advised of PB Blaster which I put on the bolts and let set for a day then reapplied again and waited another 3 hours and the rest of the bolts came out without any trouble what so ever. So since then I have been sold on PB Blaster. You can get it at Oreilly auto parts if you have one around where you are. I would suspect that other auto parts stores would also carry it.

You might give it a try and see if it works.

Good luck on whatever route you go.

As always good camping.
