Boost and high RPM's increase the amount of crank-case blow-by causing problems for the stock engine breathing system as it very quickly becomes overloaded. This can lead to oil being blown into the air-intake, increasing the possibility of detonation due to oil entering the combustion chambers. This can be solved by fitting AVO's oil/vapour separator tank kit, which removes oil mist from crankcase gas before it is returned back to the engines air-intake. The Breather Tank kit comes with all fittings and accessories necessary, including a turbo-specific high pressure PCV valve replacement that will deal with any potentionl boost leaks and protect against pressurizing the crankcase under boost. This is also a requirement for higher boost builds.

This kit also includes a oil filler cap replacement, 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.
