Air Oil Sperator == blue smoke == DO NOT DRIVE IT!!
Flatbed to shop or DIY.
You are in fine company. All older 986's will do this and is common as the RMS.
The engine sucks in the oil and causes the smoke and misfire codes. If too much oil gets into the cylinders then you have big problems.
Do a search on RennTech.org and find out all about this problem.
Take care,
