This is what I did....
(this should only be used on non emissions legal cars... DO NOT USE THIS SYSTEM IF YOU GO TO THE TRACK!!)
Go to autozone and get...
6 ft of rubber 3/4 inch hose
a new oil filler cap with a breather
small rubber caps, these will be used to cap off the TB nipple that usually has a rubber vacuum hose to the oil filler neck.
NOW....
Junk the vortech box, run a 3/4 inch or so rubber tube from the PCV running down the back of the engine block under the car, this will vent oil vapor to the underside of your car.... Now you have you that PCV taken care of.
Put a rubber cap on the nipple from the oil filler neck that runs to the TB and cap off the TB too.... put on the different oil filler cap with one that has a vent on it.... these are usually the ones that the carb guys use on there valve covers.
place the 3/4 rubber hose on the new oil filler and run the rubber tube down toward the rear of the motor to about where the PCV tube is, down by the tranny.
With this method you will ventilate your crank pressure and, if done with common sense, you will not have any boost/ vacuum leaks.
