My baby is a 96 850 turbo that just turned over 130k. Over the last few weeks ive been noticing a burning oil smell when i sit at a light. I checked under the hood the other day and noticed that there was a small amount of oil smoke coming from the back of the engine after a long drive. I know i need to replace the return line gasket on the turbo, but could it be getting oil all the way up on the manifold, or should i look somewhere else too? Thanks in advance.
