This is how the valve cover will look on your car, after it is clean off and painted to whatever color you want. I used gross black 500 degree engine paint.

The TBI cover comes with TWO PCV port, unlike the turbo valve cover with just one port. It also comes with the oil splash guard which further reduce the chance the oil will get into your air box. I used one port for the PCV valve then to the intake for vacuum source. The other one is connecto to the air box for fresh air intake/by-pass (when in boost)

As you can see, one side of the air box have no oil at all. The other side is a little wet, but that wetness is from before I did this mod. The air box works so well that I didn't even bother to clean. Don't be bother by the hole in the second picture, I had to do that to clear my master cylinder for my custom intake system.

Good indicator that there is no oil in the air box is the air filter. Mine is nice clean and dry.
