I had the same problem. The line going back to the turbo oil scavenger pump had a pin hole causing a loss of vacuum in the oil line. When the engine was idling the oil pressure (to the turbo) was lower than when the engine is at higher RPM so not much oil leaked out. When I shut down the engine the pin hole allowed the oil to leak back into the turbo and most of it came out through the pin hole. The oil line from the turbo to the scavenging pump has a vacuum in it and it does not take much of a hole to break the vacuum.

Good Luck,
