I have been looking into possible causes, but have you done any oil analysis on the system yet? I have seen reports of a bad valve (or wrong valve for an application) or even a damaged pump causing this type of fog.

Thanks for your reponse. The oil have properties in normal parameters.

the most probable is the oil leak to the sahft of pumps that lead mechanical shear and pulveritazion of oil.
