After spending the last 3 years playing working on my Galant in my spare time we noticed the turbo oil feed line was leaking while the car was idling during tuning yesterday. The car lost almost a quart of oil by the time we noticed the leak. I've driven the car about 8 miles after fixing the oil feed line for further tuning and today the turbo started making a grinding sound today after driving her a little hard.
Here's a link with video and pretty clean audio of the sound- click .
Any opinions? I'm not inclined to drive the car another inch right now and if I need to replace my turbo any suggestions. I'm thinking a 16g.
