I just replaced the head gaskets on my 5.7. I burned a gasket for as yet, an undetermined reason (see the picture at the end of this posting). I asked many for ideas why this might happen and one veteran speed shop guy said he had seen this happen due to a crack (not visible) in a head bolt later discovered on reassembly. In the interest of making sure I didnt have the problem again, I bought a new set of head bolts along with the new gasket as well as a new torques wrench. When I installed the heads I couldnt get one bolt to make the torque wrench to "click" over set at 65 ft lbs. I finally retorques all the other bolts (on that head) and when I loosened that bolt and retorqued it just snapped off. I was just wondering if anyone else has ahd head bolts crack and cause gaskets to blow ot if they had new ones break off??<br /><br />By the way all is well though it cost me a couple of extra hours, I pulled the head again and was able to tap out the bolt with a screw driver and reset the head and use an old bolt (from the other head that didnt burn the gasket just in case!!). I will try to start her up later today.
