Search is not broken, though the link does not work. Apparently a catch can catches oil and fuel fumes and prevents it from entering the crankcase. Having fumes in the crankcase lowers you're effective octane rating. All that from 1 thread. OK done spoonfeeding. Can some1 this guy for being noob?

Prevents oil from entering the crankcase, are you flippin serious?

 

I think the main benefit of a catch can is to keep oil vapors that come through the PCV away from the intake. The oily residue makes a mess in there, and contributes to EGR blockage where the EGR tube joins the intake.

 

Just remember that you need to catch can the PCV items on both sides, not just one like everybody always does.
