Maxidyne, can you explain why a catchcan is better than just letting the oil go back in to the oil pan?

You mean reusing the old oil again? Never done that. Always use new oil. Old oil loses it's lubricating abilities.

Evo's use the Positive Crankcase Ventilation (PCV) system is the "vent" for this build up of pressure inside the engine. The problem is, the gases vented through the PCV system contain oil vapours and they are dumped back into the intake system to be burned. Since they are rerouted back in to the intake pipe of the turbo, over time, everything between the turbo and the cylinders will get a build-up of oily residue. Even worse, charged air containing the oil vapours is condensed through the intercooler and much of the oil will build up inside the front mounted intercooler.

A catch can "catches" oil vapour before it is sent back to the intake pipe, substantially reducing the amount of oil that can build up inside the intake tract and winds up a greasy mess inside everything between the intake pipe and intake valves.
