If you pass too much vapour back into the inlet it can cause excessive carbon build up and pre-ignition and detonation. It also lowers the output of your engine it kinda defeats the object of putting say optimax in if its pumping gasses into the inlet which has the opposite effect that the higher RON rated fuel has. It wont be a significant difference but on say a high boost aplication it can dramatically effect the amout of boost you can run!!! | |

in addition to the lubricating, its there as part of the crank case ventilation system, in the olden days this used to vent to atmosphere underneath the car, it vents blow-by gasses and toxic oil vapour that collects in the crankcase. | |

i asked this exact question on mig yesturday, basically you need to keep it there as it lubricates the turbo and stops the veins rusting up. however a oil catch tank is the best option, but the chanes are there isnt much oil that goes down it anyway. | |

i've heard people say that the vapour acts a lubricant and rust prevention on the fins of the turbo? Or is this just crap? | |

its for environmental purposes, oil vapour is a little toxic, my breather runs down behind the front arch liner and exits towards the floor, ya dont want toxic vapour in ya engine bay, it smells and gets sucked into ya air vents and blown into the cabin, | |

you can make a oil catch tank and put a breather filter just after it, itll be ok | |

I am considering a rethink of my induction set up which will involve removal of most of the standard OE induction piping, coz its too long and very restrictive. |
