After perusing the searched threads, I don't have much to troubleshoot about this. So here goes; I had the turbos rebuilt recently. Had a incident with the first rebuild, took it back, and had them warranty-worked and rebuilt again. Car's running pretty good for couple of months now. But, I do smell oil burning. It's not every time I drive, but enough to make me paranoid. Here's the kicker ... there's no smoke. Smells like it's coming from the turbo assembly area. Exhaust is good, smells like fuel (normal). 4500 miles, 2 oil changes, and I only needed to add 1/2 a quart during that timeframe. Is this a crush washer in the oil lines to the turbos or some other small oil leak that I haven't found?
