Well I have a small stream of smoke out the tailpipe. I know for sure its oil but from where I don’t know. I of course did the obvious and checked the compression and found that all the cylinders are dead even so its not the rings or a blown gasket. Im thinking that it is one of two things. Valve steam seal or leaky turbo. It isn’t a large amount of smoke and the only time you can see it is at idle and even then it evaporates off about three feet off the tail so its not a huge leak (yet). When I start the car it won’t smoke for about 5 min of idling. What’s your opinion valve steam, leaky turbo or other?
