So my care only has 4300 miles on it. I recently installed a turbo back catted exhaust and a BOV. Everything seemed great....though I did notice a bit of white smoke coming out at 1st I attributed this to new exhaust packing. I figured it would burn off after a few days. Fast forward 4 weeks and the smoke coming out is even more than ever. I mostly notice it when idling for a bit, say maybe 3-5 min. No revving just idling. Then light smoke starts coming out. If I gun it then a whole cloud comes out....all white and smells of oil. Don't notice it when i start driving. Seems to go away for the most part...until I have the car idiling again. Only other mod is Cobb tuner and intake. I ran a diag and came up with no codes. Thinking of unmarrying the tuner and returning back to factory specs to see if the problem still exists.

I do my fair share of slamming the hammer down but just for a single run or 2. I don't redline or hit the rev limiter as i know power falls mostly after 5500.

Any ideas? anyone else have experience with this? This is my 1st turboed car. I'm hoping there is a fix without having to take it to dealer....as then i would have to remove the aftermarket DP and place the factory one back on. Again, this problem wasn't present before the exhaust mods AND i have a hi-flow cat.

Just look up white smoke Ecoboost on this forum. That should be a start to explain what's up.
