Rusty headers

What is the best way to get headers off where the top bolts are rusted? And one is stripped some.

Heat, something like an acetylene torch.

Re: Rusty headers

First try soaking it several times over the course of a day with some Liquid Wrench. That stuff works wonders. After that, before you go at it again use some degreaser on the bolts to get the Liquid Wrench off the surface to avoid slippage. If they are anything like mine, if you have a completely stripped nut you still have two more chances to get it out. If it's a stud type the end of the stud has a small hex head on it. You can fit like a 4 or 5 mil on there and if the Liquid Wrench does its job it will come loose. Then if that doesn't work you can clamp a pair of vise grips on the stud. Worst case, if that doesn't work then by this time you have sheared it off and when you get the header off you can try again with what's left.

Going to try as soon as I'm free again and it warms up a bit. It got cold here again. Did a quick fix with some collectors to make the exhaust last for a few weeks.

Re: Rusty headers

Ah. Exhaust leaks just make the vehicle sound meaner! I think there is a tool out that uses steel pins to adjust to the bolt you want to remove, which helps to remove rounded, or broken bolt ends. Header bolts that I've used in the past are TTY, you might get lucky and be able to loosen it after spraying it thoroughly, and using some heat, with a pair of vice grips versus a small wrench. Just a thought.
