I'm not sure yet. Will require tearing the engine apart to determine the official cause. I'm in the process of determining whether it is worth it to tear apart / rebuild the current motor or buy a replacement. Obviously it will not be worth the time / money to determine the cause if I plan to scrap the existing engine.
To be clear - this is not an M3 engine problem. I witnessed M3's running flawlessly at the track all day!
