It sounds like you may possibly have a bad cylinder and/or piston. The oil spray and rough running engine leads me to believe this. Has a compression test been ran on the engine? If not, this will be the first recommended diagnostic test to determine if there is internal engine damage..
Keep me posted...
The oil separator is designed to do nothing but attempt to separate oil from crankcase vapors and drain the oil back into the engine so that it won't get drawn in by the turbo. Oil spray from the oil separator is a symptom of excessive crankcase pressure. When this happens, the oil separator cannot separate the oil fast enough and will cause oil spray through the separator. The rough running engine leads me to believe that the loss of compression past the rings is causing the excess pressure in the crankcase and the resulting oil spraying out the oil separator.
I've also seen this condition actually blow oil back up through the dipstick tube when the engine is running and the dipstick is not fully seated in the bore. Try removing the engine dipstick with the engine running and see if oil blows up the dipstick tube..
Any time I've had those symptoms, each vehicle needed engine repair. Compression test is the best starting point to determine if you want to spend the money on engine repair if it ends up going that way..
Keep me posted and let me know if you have any additional questions...

No, definitely not, If there is compression loss past the piston rings, there would be no way to stop this problem from happening other than doing a proper repair on the engine..
