No sounds like the compressor seals may be blown on the turbo.
Mine did that only after hard running on the track upon startup after sitting between sessions. Check down inside the compressor housing inlet to look for oil and oil inside the intercooler. This would confirm trouble. Fred

Classic symptom of worn valve seats.
Engine cools, parts contract, oil seeps past the seats and into the cylinders. Start the car, oil burns off, parts expand, no more smoke. Rinse and repeat once the engine cools down.

All of the above and it may be worse if the oil level is at the top of the "safe" range on the oil tank dipstick. Alot worse if it's overfilled.
When the oil level is towards or at the bottom mark on the dipstick it may not be as bad... if you're lucky. |
