[QUOTE="Uncle Meat, post: 15179376, member: 5089"] Okay so I'm still looking at getting a complete turbo-back exhaust for the wife's Mustang (catted and resonated of course). However I'm seeing numerous reports of blue smoke at idle after replacing the factory down pipe. Now most of these reports are from cat-less down pipe installations, but this just means the catted down pipe is masking the issue. Seems the Ecoboost has an issue with crankcase pressure at idle. One of the "Band-Aids" recommended from a respectable tuning company was to change to a heavier oil or raise the idle to 900-1000RPMS. WTF!? That's not a fix. One guy reported that gutting the PVC valve and adding a double oil separator worked for him. Not sure I want to invest in a full turbo-back exhaust if the darn thing is going to require additional modifications to prevent it from burning oil while sitting at a stoplight. Anyone want to weigh in on this dilemma? U.M. [/QUOTE]
