I’ve got a 997.2 TT had some smoke on startup. Noticed that the bumper on the passengers side has some oil residue on it from the exhaust.

I pulled the turbo hose off a few months back and collected about 1/2 to 3/4 cup of oil. Not sure what the issue being, I cleaned it up and drove the car some more.

I noticed the same issue again today so did the same procedure and maybe 1/2 cup came out.

Any idea what it could be? The oil fill is well below the top hash mark. See picture for reference.

The car is modded. It has 3 inch catless exhaust, AWE intercoolers, AWE headers, BME filter, IPD y-pipe and plenum. The tune was done by Sam at ByDesignAuto.

No CELs on at the moment. I’m stumped. At first I thought it was blow by but this seems very excessive.
