After my engine rebuild i finally got the engine back in my car today. After i primed my engine yesterday i was little frightned. I used a smal drill and pump to pump oil trough oil cooler feed and back in to the engine. After pumping about 2 liter of oil i noticed the passenger side turbo was wet under the exaust side of the turbo. I wiped it off and gave the engine another two liters of oil but nothing seemed to be wrong at the time. Today after dropping in the engine the driverside turbo had the same symptom. It looks like the oil could be from inside the turbine housing and are laking between the turbine housing and the center housing. The turbos are brand new from one of our sponsors. Are the turbos defect? If so, why?
