i bought a used ATP gt3076 with about 8000 miles on it for my mazdaspeed3 and i know it had been sitting for 3 months. it had no signs of any leaks when it was taken off and i had a shop that deals with turbos on a regular basis look at it and they said it looked fine. anyway when i was home and the turbo off the car i plugged the oil feed hole and filled the turbo with oil on the drain side to let the bearing soak in oil for 15 minutes just because i felt like it because it had been sitting. anyway i had the turbo laying on the compressor outlet so it was at a slight downward angle. anyway today(2 days later) i noticed oil had started running down the compressor outlet on the turbo. is this normal for oil to seep thought when its not on the car with no oil pressure?? or did i buy a NO good turbo
