Having oil pressure read high upon startup is normal. That is because the oil is COLD and THICK. After it warms up the pressure will drop but should be around 90 to 100 PSI. This is dependent on WHERE you are taking the oil pressure reading from. At the back of the engine 90 - 100 PSI. At the front of the engine 80 - 90 PSI. The fix is easy - Just increase the pressure with the adjustment of the By-Pass pressure that is near the #3 cylinder. Some adjustments have a threaded rod with a nut on the end and should be safety wired. Other require you to open the unit and install washers under the spring. Ask some one at your airport to show you where and how this is done. It is a little tricky because there is a check valve that you DO NOT want to lose or damage or get dirty.

What you're describing seems pretty normal. 85 is a little on the high side and can be adjusted either by removing washers from, or turning the adjustment nut counter-clockwise the, bypass valve behind cylinder #3.
