S4 TII burning oil?

I was messing with the vacuum lines on my FC Turbo and after I got them all sorted I drove it around shopping for a bit with no issues. Later on in the day, I went to pick up a friend and it started up normally, but after letting it idle for two minutes it started to billow out blue smoke. I shut it off and shuttered it for a day. The next day I drove it around and it drove around alright but still spit out blue smoke. Now, whenever I start it it will run normally but after a minute or two it will start spitting out smoke again, I'm not sure if I messed up a vacuum line or if its something unrelated.

Thanks.

Due to the fact that rotaries burn oil by design, some blue smoke on startup is completely normal. However, if you have previously flooded the engine and fuel has gotten into the exhaust, smoke may appear a minute or two after start up and last until it has been driven around a bit. If you're shutting the car off before it's warmed up fully, chance is some fuel is getting into the exhaust. Does it continue to smoke even after driving for a while?

yea, it will smoke whenever it's stopped and idling. I'm pretty sure its the turbo oil seals.

turbo oil seals seem about right. Time for a rebuild

Yea, already rebuilt it. Just need to get a new crush washer for the coolant banjo bolt because the one from Atkins doesn't even come close to fitting and the ones I got at Orileys are leaking bad.

After that it should be good to go :P
