No evidence of oil when I pulled the heatshield this morning. The car ran great and didn't smoke out the hood or tailpipe at autocross all day. It even got faster in the afternoon.
I'm going to pull the IC and Y-pipe. If there is significant oil in there, I'll take it to Kspeed to have them swap the turbo. If not, I might just wait for it to get worse. Thoughts? I'd rather error on the side of safety if anyone thinks I should just swap the turbo to be safe.
