Visible smoke from exhaust between shifts

[bsbllfit7]

Hello everyone just trying to find out whats wrong with the car. Its a 1995 Talon Tsi AWD with 109XXX miles. It had a head rebuild within the last 25K miles and is running on the stock T25 Turbo. Now just recently i have noticed that when i boost fairly hard and shift gears when i start to accelerate in the new gear i can see a puff of blue smoke behind my car and can smell the smell of burning oil. I have just installed a catch can between the valve cover and the intake tract. Just trying to figure out what this problem is.

Also i checked the turbo for shaft play and it was very very minimal if any play at all.

I'm having the exact same problems with my dsm in between gear plus one symptom. After a hard pull if i push the clutch in and cost I get white smoke. Also after i 2 step i'll get a puff once the car is back to idle. But i don't get any smoke under load. I can tell by the smell because I'm running e85 so that over powers everything. I did a boost leak test and found I was getting pressure in the valve cover so i replaced the pcv and it has no effect on the problem. I haven't had time to do a comp test or another blt. It is worth noting that this problem didn't show up until I just put my new exhaust on and retuned it.
