Good evening,  
We have noticed a continuous rise in the level of the M/E scavenge drain tank. Do you have any idea of what could this might indicate?

Good question! It could possibly mean that there is system oil leakage inside the M/E scavenge space probably coming from the o-rings of the M/E piston crowns! The above can be confirmed during a M/E scavenge space inspection with the main lube oil pump running.
