Warning No Oil Pressure - No Engine
New and overhauled aircraft piston engines are subject to oil pressure anomalies, primarily due to loss of prime that normally occurs after one of these conditions: • engine installation • after periods of inactivity • after oil change • after major weather changes
After an engine installation, oil pressure must be established on the engine prior to the initial start up.
Attention should always be paid to oil pressure coming up at every engine start...within 15 to 20 seconds.
Extreme attention must be paid when the above mentioned conditions exist in order to avoid internal damage and ultimate failure of the engine.
Pre-oiling with a pressure pot is highly recommended. With the spark plugs removed, turning the engine through with the starter is also an acceptable method, but use extreme caution around the moving propeller.
Note: Bleeding the oil line from the engine to the oil pressure gauge at the fitting will help the gauge show real time pressure much quicker. While running the engine, have an assistant catch the residual oil in a cup at the gauge end.
