Excess crankcase pressure (sometimes known as "blow-by") is vented from the crankcase through the PCV system, where it is drawn into the intake manifold and returned by the engine. This re-circulated air contains aerated oil from the crankcase which is burned by the engine. Supercharged, nitrous boosted and high mileage engines often draw excessive amounts of oil into the engine through the PCV system. The Steeda oil separator plugs into the PCV hose between the PCV valve and the intake manifold and removes aerated oil from the re circulated air and collects it in a tube that can be drained and recycled.

Oil separator kits include the oil separator and all required hardware.

Product Benefits

• Increased engine component life
• This kit reduces detonation, oil burning and deposits on the valves by removing oil drawn through the PCV system

STEEDA UK INSTALL TIP:
Check to make sure air flow through the separator is going FROM the valve cover TO the intake tube (arrow on top of oil separator for flow direction ).
