I know this is gonna sound kinda stupid but i recieved my turbo kit recently and as i was well aware of the turbo had four lines two for water and two for oil. To seperate the two i blew down each feed line, i discovered which ones were which by doing this but upon blowing down the oil feed i could hear air (only a tiny bit) coming out of the exhaust flange. By nature im a perfectionist and as its getting extremley close to install time im kinda concerned that i may have a bad seal or something in the turbo and i dont want to be blowing oil into the exhaust. Is this nothing to worry about as the tubo is a brand new T25bb. Please Please someone share their knowledge with me! Every bit helps.
