Some RX-8 owners have been recommending installing an oil catch can, to prevent problems from "overfilling" the oil.
I assume this doesn't mean spillover (does it?), but instead, too much oil in the system. The idea is that this oil can make it into the intake and cause problems.
How does oil relate to the intake system and how does a catch can fix this problem? Does this alleviate the risks of filling the engine with too much oil?
