I have looked at the parts manual and maintenance manual and don't see a valve. What does the go480 installed in a 1955 560A utilize to trap oil in the tank when static? Any help?

It will show a difference of 2 to 3 quarts between cold and warm engines. I always check the oil after shutting down to get an accurate measurement.

Curiously, only the left engine does this. I was told there is a valve between the tank and the engine on the 560A but I don't see it on the plane or in any of the manuals. Do you think this would add to oil consumption or extra oil lost in the seperator? Again, thanks for the interest. scott Read this topic online here: http://forums.matronics.com/viewtopic.php?p=191181#191181 ________________________________ Message 5 _____________________________________ Time: 11:38:28 PM PST US From: "Richard & Jacqui Thompson" Subject: RE: Commander-List: Re: 560A oil tank draining Scott, The answer to the oil draining into the engine is. The oil pump main pressure relief valve has a spring loaded check valve which stops the oil draining into the sump. This valve could be worn, damaged or have some gunk in it thus allowing the oil to pass by. It is mounted on the back of the pump. Be aware that the reason you always pull the props through before you start is to check that the cylinders have not filled with oil. This happens when the crank case fills with oil and it gets past the rings. Hydraulicing the cylinders is not a good thing, can bend con rods, blow the cylinder head off etc. Generally very expensive. Have your mechanic pull the relief valve and check it out. Remember to reset the pressure after.
