AVOTurboworld's Street Oil Breather Tank kit for the BRZ & FRS/86 provides a solution where the amount of crank-case blow-by increases and causes problems for the stock engine breathing system as it very quickly becomes overloaded where big RPM's and big boost is involved. This can lead to oil being blown into the air intake, increasing the possibility of detonation due to oil entering the combustion chambers.
AVO's oil/vapour separator tank kit removes oil mist from the crankcase gas before it is returned back to the engines air intake. The kit bolts onto the factory strut tower and comes with all fittings and accessories necessary to complete a successful installation. One special item in the kit is a turbo-specific high pressure PCV valve that replaces the factory PCV Valve, this will deal with any potential boost leaks and protect against the pressurizing of the crankcase under boost. Another unique item in the kit is the oil filler cap that allows you to directly route excess oil from the turbocharger oil reservoir tank back into the engine. This is designed to alleviate any overflow issues from extended high rpm usage at the track.
