Oil breather catch can?

[Burn N' Up]

Oil pools in the IC piping because of the PCV hoses. Climb aboard the Magic Supra School bus and away we go to your MK3 Turbos engine compartment....

Look at your intake(accordian) tube it has three hoses coming off of it, one of which is the main concern of our topic. The one that is most centerline of the others leads to the Positive Crankcase Ventilation hoses, these are the two hoses that come off the top of the head and connect to the pipe just to the rear of the 3000 pipe. These hoses suck oily vapors from the crank case up and into your intake manifold for reburn, thank you very much EPA. but coincidently they also suck vapors into your intake manifold =O =( This way there is always vacuum pulling on these hoses either from intake tube or from the throttle body because the PCV hoses connect to the throttle body past the throttle butterfly valve. But here is where the =( comes from. Go to the intake tube that you now know is sucking HOT OILY vapors into your turbo charger who happily mixes it with the charge air making it even hotter from compression (see Boyle's Law) it heads down your IC piping and once reaching the IC it gets cold, and thus condenses turning those oily vapors into sludge stuck to the inside of your IC and all post IC intake pipping. So, is this a usual problem in turbo cars? As long as the EPA has something to say about PCV, yes it will be.

The Breather Can basically takes these vapors and lets them cool off inside it dumping the oil there... instead of in your IC. Not sure if you need to hook the PCV hoses back up for smog or not.... Just hook both sides of the PCV tube (the one behind the 3000 pipe) to the can and voila.

Edit: It does create a small air leak that wasn't there before that the car will adjust to. So don't worry about that little bit of rough idle you get initially. I forget ho many drive miles or minutes it takes to get reprogrammed but 30 minutes is not uncommon.
