The way I see it we must have lost the engine oil. The decreasing oil temperature followed by loss of oil pressure means no more oil to me. I know that the breather lines from the outlet to the rear baffle was not insulated. I still have pictures showing that. Maybe the breather line was blocked due to the low outside temperature and the oil pumped out somewhere because of that. I was not aware that it is a good idea to insulate the breather line. I have previously owned two Aztecs and the breather line on a Lycoming are behind the baffle on the rear part of the engine. This is pure speculation but maybe some of you have some experience on the subject.
