Yes there are, one is to not sit there ticking iver for longer than 10minutes, the other is switch to 5w40 oil in the winter, the third option is to buy a banjo bolt from totalmps like i have. They all do it, its because the oil feed to the turbo is to much and will seep through the seals. The banjo bolt prevents that from happeing. Its very common it doesnt always mean your turbo is going. It happens to these and the 3 when they were brand new. You can also buy the moded rocker cover with the better pick up and feed sorted.
