My CEL has came on again. I had just replaced the O2 sensor after it had cam on the first time. I had the code cleared and it was off for about 2 days. Then it came on again. I have been noticing more and more blue smoke upon start-up and was a quart low at my last oil change. I realize that the most likely cause is turbo malfunction, but are there any other options i have besides dropping it off at the service center along all my money? Are there rebuild kits available or seals that can be replaced? I have a friend that has a stock turbo off a mitsubishi eclipse gst, i believe a td05h. would it be possible for it to fit and run properly? sorry for all the questions, i am just trying to gather myself.
