Hi: I am not sure of the details, but my dry sump returns from the oil pan on two suction lines then a pressure line through the oil coolers and back to the reservoir, which supplies by gravity to the intake of the engine oil pump/filter. So....If Tony's system is similar to mine, is there a chance that there is tramp metal in the dry sump pump that got there when it was scavenged from the oil pan after it left the turbo? I know that I am having my dry sump pump rebuilt after the cam shaft seizure. Price quote was about $200 all in.
