Please I ask you for help or some idea to solve this problem:I have changed the oil circuit pipes, I have bought them at an official Aviasport dealer in Spain, I have also changed the oil I always use Aeroshell Sport Plus 4, I have also changed the oil filter bought at Aviasport.I perform the purge according to the Rotax Bulletin, I start the engine and I have cold 5 Bar and hot 4 Bar, OAT 18 degrees Celsius, when normal for me when hot is 3Bar.I place a mechanical pressure gauge in the port of the Governor, the results are 0.5 Bar more in each situation.I tried uninstalling the new oil filter and putting in the old one. The results were the same.Try installing a new oil pressure regulator with its three components valve pressure, spring and screw. The results were the same.I tried removing my oil thermostat and testing the circuit without it. The results were the same.I dared to do a test in flight, in hot and cruising 4 Bar, when before it had 3 Bar, in idle and in descent it drops to 3 Bar, but as soon as the oil cools it returns to 4 Bar, when before in descent it always maintained 2 , 5 Bar. Coolant parameters and normal oil temperature.Thanks for your attention.Alejandro ZapataSpain
