VT 365 TURBO

I HAVE A VT 365 TURBO LEAKING OIL IN TO INTAKE SIDE OF THE TURBO, THE RETURN LINE IS OPEN SO IT CAN DRAIN INTO THE CRANK CASE. HAS ANYBODY HAD THIS PROBLEM?

is the oil coming from the turbo or the crank case being recirculated back into the engine

if the crank case I do remember Int. saying that it was normal. I believe he said this when we were in that VT365 class they gave

my memory could be bad but I thought that was what they said
