Can you add egt's to see if it's fluctuating on one side and not the other? Another idea is to get an infrared temperature gun and tie the plane up and have somebody run it hard while you check each cylinder or keep it on the same cylinder and see if the infrared tracks the gauge.

Any really quick temp changes would seem to be sensor or possibly gage problems. Actual readings can move 10 to 15 degrees in the span of a couple of minutes due to oil attitude in the pan, but quicker than that, I'd be looking at replacing the sensor and doubling the gage for comparison.

I think in retrospect, the best solution would be to grind and re-weld the crack and add the cross bar reinforcement. I donated the one I received to a friend that also had his crack at 65 hours. In weld repair, I'd suggest you get someone that has good skills at TIG welding or oxyacetylene welding so as to not spread too much heat into the part. This is a very safe repair if done carefully.
