Richard.
Thanks for the info. I assumed there was a check valve somewhere. I will
look in my lycoming overhaul manual for a description. Based on the replies,
I
am not the only one with this issue.

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.
Cheers
Richard

thanks for the replies. 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.
