I'm changing the head gasket on this truck. Here you can see the exhause manifold bolted onto the upper intake, which I am trying to remove.
And here is the reason I would like to remove the exhaust manifold from the rest of the exhaust.
One of the bolts that holds the manifold onto the upper intake has had its head snapped off. There is very little clearance around the bolt with the broken head so I can't remove it without taking off the A/C condenser and maybe even the passenger side wheel well.
But If I can disconnect the exhaust manifold from the rest of the exhaust I can still pull out the upper intake, with the exhaust manifold still attached. The problem is those bolts are rusted.
I've sprayed a ton of PB Blaster on that bolt, hit it with a wire brush, and used a torch on it. It won't budge. So can I just cut it in half with a hack saw? If I do will that separate the exhaust manifold from the rest of the exhaust? I'm hoping that once the bolt is cut in half it will be easier to remove.
Here's an image of the exhaust manifold. I'm pretty sure I can get away with just cutting through the bolt. Will it be hard to get the bolt out once I cut it? I imagine it will be easier because I'll have it out of the truck and there will be half as much resistence.
