In the "Engine Building Tips From the Pros - Are EJ-Series Engines as Weak as Tuners Claim?" article I posted earlier, I recall Crawford Performance's comment:
"We highly recommend the use of an air/oil separator (AOS) on any turbocharged EJ motor to eliminate oil from coating both the intake tract and the inside of the intercooler, which causes a reduction in cooling efficiency that can cause detonation."

Oil vapors in the intake tract also lower the effective octane of fuel, so this is another reason that suggests oil mgmt measures are important.
I found 2 mods that help manage crankcase oil, and wanted to know how important they might be to machine performance:
1. Grimmspeed AOS ($285), and
2. KillerB Oil Baffle and Windage Tray ($85).
What do you think?
