One of the things that I asked about a long time ago was the fact that my temp gauge always seemed to creep up when I had my headlights on (in the 4kq)...
Seems like the ground on the gauges gets in pretty poor shape, and the gauge reads high, especially when the dash lights are on.
I can get my indicated oil temps to drop by 10-15 degrees Celsius by using the dimmer for my dash lights (when they've been on for a while).  Ought to get around to fixing that.
Might be worth checking that ground anyhow, and seeing if it is causing a problem.

Good Luck!
