[QUOTE="extreme33, post: 1408237, member: 26196"] Rich, Thanks for the reply. 1. I install new stubs each time the top of the cylinder gets hand sanded / emery cloth (which is almost every time now). I use a granite slab (purchased from Rockler.com for a perfectly flat surface). Figure eight motion over the wet emery cloth to make sure there isn't any warp. Still using the original nuts (without locktite). 2. Craftsman torque wrench. I establish a calibration ratio before every use. Clamping the wrench end in the vise and using a 20lb weight (accurate within 0.002 lbs) string method. Wrench is within 1% of the setting and it's always turned back to zero when not is use to prevent spring drift. 3. Torqued in an alternating pattern (1, 3, 4, 2) and incrementally. 1 is front left and direction is clockwise. 4. Doesn't always leak in the same place but sometimes it's not possibly to find the leak location with the copper spray coating. My theory is the gasket isn't wide enough at the location next to the water jacket. Not sure at this point. [/QUOTE]
