agreed with skull, however, not sure if you will find a small enough torque wrench. just open it up and use the AM RROD repair tut to put it back together, over heat and retighten. the biggest thing is not to tighten one side then the other, give it a few turns on each screw untill all are tight, if you do one side then the other, you have the chance of cracking the chip, and as you can imagine, that is bad
