912ULS oil and hose change
Just completed 5 yearly hose change out and 100 hour service. Things did not go as per text book. Firstly when attempting to pressure tank to 9 to 14 psi I was unable to maintain any readable pressure on gauge. Undaunted I must have spun the prop some 300 to 400 times and actually put some 7 litres of new oil through before exhaustion made me quit. However on first start up had instant oil pressure although fluctuating over 10 mins between 3 to 7 bar. Checked lifters and all hard. Performed several additional ground runs and pressure evened out to a steady 3.5 to 4 bar. Now flown for an hour and all seems stable at 3.5 bar. Sound familiar?
