Oil in Belly

[GAdams]

My 1969 D Model has fresh oil IN the belly in front of the landing gear transmission. No further aft than 1 compartment and no further forward than two compartments. The color of the oil is yellow like. Same as fresh engine oil. I know the transmission has no oil in it. I also know the gear legs have no oil in them. Also the fluid used to actuate the landing gear system is 5606, which is red. I can't find the source and the amount is not very much but enough to pool. Does anyone have any thoughts? Insights? I've cleaned it up before and it comes back. Also it comes out of the weep hole in the belly compartment and streaks back in the airflow on the outside of the airframe.
