#62079, "Valve steam seal or leaky turbo?"


          

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?

TIA
Brian

Only way to know is take a look. Pull the turbo and check for play.
Pull the exhaust manifold and look at the valve stem seals you'll see the valve stems wet if the seals are leaking.

hmm whats your vacuum like? Does the needle shake at idle. If it does it's probably your valve stem seals. I replaced mine and it seems to have worked, the needle doesn't shake as much. i probably just have some kinda vacuum leak now.
