June 12, 2007Johnny, just wanted to let you know that breaking exhaust manifold bolts is a possibility. I would still do them but lubricate them as much as possible beforehand and if you do break one it is easily repairable. Mine just happened to be all the way to the back in a very tight spot. I didn't enjoy starting a head removal at 5 o'clock at night but on the good side my cylinder walls are in great shape. Armed with a torque wrench and a manual you can do almost anything on these trucks.
