Recently while flying back from Texas, I noticed my oil pressure was past the redline and the oil temp was climbing close to the redline of 245 degrees. I made a precautionary landing. Now no one seems to know why this happened!! The is an 0320 with 250 hours since factory new. The IA said the oil presure followed the throttle to 110 lbs and it shouldn't do that past 70to 80 lbs of pressure. First, he removed the "varatherm", which was no small job. It checked fine. Never found any reason for the sudden high oil pressure or temp, so he is turning down the oil pressure regulator so it now will read 45 lbs at idle as the solution. He did hook an external pressure guage to the rear of the engine to verify my guage. The filter was cut and nothing was found. Can anyone think of anything this might be? Just turning down the regulator to me doesn't fix anything. Of course it had plenty of oil.
