An oil/air separator, also known as a catch can, is designed to separate oil and moisture vapor from the gasses exiting the engine’s positive crankcase ventilation (PCV) system. In factory form, the PCV is plumbed into the intake system. Without an oil/air separator, air mixed with oil can find its way back into the intake system, which leads to the combustion chamber. This leads to increased carbon build-up, decreased performance, and greater emissions, and it could reduce the effective octane level of gasoline, as oil has a very low octane value. Reduced effective octane level could cause engine detonation or “knock”. The RZR Pro R Oil / Air Separator System prevents all of this by firstly separating and catching the oil and moisture exiting the crankcase, then venting to the atmosphere in race applications to ensure the intake tract remains clean of crankcase oil.

The Weistec Oil/Air Separator System accumulates oil and moisture in the lower body, which can be easily drained and recycled. Some vehicles may have more oil consumption or “blow-by” than others. If you are unsure whether your vehicle may or may not be one of these, check the oil separator every few trips to ensure the separator system is not filled.
