Removing the exhaust manifold

[n7188u]

I have a 787 engine that, when I tried to remove the exhaust manifold, the screws feel very tight. I didn't force it since last thing I want to do is break the screws. Any suggestions on how to remove them. Only thing that occurs to me is to use a torch to heat the screw although the engine such a massive heat sink I doubt I can get any real temperature on the bolts threads.

Nope... you would never get enough heat on it to break them loose. They aren't supposed to be very tight, but I know I've seen some that were hard to get out.

Just get a good fitting Allen wrench, and crack them loose. (they don't normally break)

Thanks Dr. I will give it a try and see what happens.
