Over the past few months I have been attempting to rebuild the engine in my 1520 that broke its crank. I took the block and head to a reputable machine shop to get the head rebuilt and check the flatness of the head and block. They also rebuilt the rods and checked the main bearing saddle to see if it needed line bored. I installed the sleeves using liquid soap per instructions. I used plastiguage to check main bearing clearance with the new crank. When I torqued the head on today things seemed to get squirrely. After torqueing the head down the right side of the head gasket seems loose. I can actually move it up and down a little with my finger. After I torqued it down I sat down a minute to let my back pain ease up a little. While sitting there a sharp metallic ping came from the engine. The young man helping me heard it also. After this I tried the torque wrench again and they all tightened a little more. I am pretty sure the gasket shouldn't feel loose like that. I feel lost and almost sick. This is not the first engine I have built but it is my fist deere. Any help/guidance is welcome.
