About two weeks ago, pretty sure I blew the turbo. Heard something grinding, then next thing I see it's smoking quite a bit. Car ran fine, didn't overheat or anything afterwards, just started to smoke and I didn't push it and just drove home. I haven't had time to have it repaired so I've basically just started it daily and let it run for a minute and driven it 2-3 blocks every few days the past two weeks. Yesterday I heard a little valve tapping (yes, I've been checking the oil) and observed something on the driveway for the first time. Two orange trails on the driveway and I see what appears to be rust collecting inside at the bottom of the tailpipe. Thoughts? Thanks for any insights.
