An oil catch can catches or prevents the oil from re-entering the intake tract. A catch can is placed right after the PCV and before the intercooler. This means that a more pure (sometimes 100% pure) air mixture will go through the intercooler and intake valves. A more pure air mixture entering the intake valves means no caking and none of the symptoms listed above.

An oil catch can typically uses steel wool or a baffle system that removes the oil from the air-oil mixture. Higher quality cans use the baffle systems since it is less messy and better at separating the mixture. The oil falls to the bottom of the can where it is stored until the can is emptied.

An oil catch can doesn’t add any power or make any cool noises so it is often overlooked when modifying vehicles. However, a catch can will ensure you are always running the most power possible by having a cleaner intake tract free of oil.
