I believe that it is to catch oil and such that is being blown back into the intake at high RPM's on forced induction engines. But that's just going from context from a few things I have read. We should wait till someone that knows answers :razz:

Oil catch can is for turbo applications. It helps reduce oil blowby back into the intake from the intercooler. You'd notice a reduction in the amount of oil in your intercooler if you were to pull it out and look inside. Really only an issue in high boost, large frontmount cases where the oil has time to settle out of the air, but some people like having them. I personally don't think its neccessary.
