Oil leak and smoke
Over the weekend I changed my oil
And I romped it on a couple straight aways. Then I smelled oil and looked around. Oil running down the down pipe, on the side of the engine, and around the oil cap. And I had oil smoke during idle. Any thoughts of what to look at? |

Turbo oil feed lines. If you still have the engine cosmetic/acoustic cover on it'll be very difficult to see any leaks coming from this area. Once removed, be prepared for a mess. Usually the line that runs on top of the turbo housing group, U shaped, is the cause. There are 3 lines total.

There's a video below to show how to replace it. I did mine and it wasn't cracked but brittle. |

The tube is intact but there the flexible tube behind the turbo inlet is cracked and very brittle.

gasket??
thinking of it I would try to remove it and check for any blockage.... it shouldn't leaking close to the valve cover as it is should be pretty free flowing all the way to the airbox |
