In an attempt to clear some fouled plugs, my partner ran the engine in the runup very lean for a while and said he saw the oil temp above 400 degrees before he realized and pulled the power. Engine is an Aerosport IO-360 with dual electronic ignition and automotive BR8EIX plugs.
1) Is an oil temp of 400 degrees even possible without causing a fire? I'd have thought CHTs would have exploded well before oil ever got that hot.
2) What kind of damage could be possible if it did actually hit that temp? The plane is currently grounded at an airport about an hour away from home and I'd like to bring it back where we can work on it, but I'm afraid to hop in without knowing what could have been damaged that may not be caught in a standard runup.
