This reminded me that when I replaced the stock intake with the V1 intake from EuroCompulsion, I noticed a small amount of oils sitting in the inlet to the turbo. I wondered at the time if this was normal, but once I buttoned it up, out of sight, out of mind.When you get an oil change, insist on looking at the crankcase as soon as they remove the belly pan. My oil line connection to the turbo charger was badly leaking. The service tech will probably just wipe it off and you will never know, wondering what those oil drips are in your driveway. I got the service manager to look at it. Tightening the flange bolt doesn't seem to help. They asked me to bring it back next week (tomorrow). I'll post what they do to fix it.
