greg, check the Top Down rambling thread...i posted my reply there. hope it helps.

 

1 to 2
3 to 4 (intake tube)

 

Thanks guys It make sense to me, I hope this is right!

 

Installing the can the "JDM" way does nothing. The front breather fitting is there to let air into the crankcase, not out.

Install the can on the PCV valve line.

 

Im gonna install mine the way slow has his but I'm going to T off from the PCV valve and other hose that connects to the valve cover.

And the return line back to the thorttle body and intake tube.

 

T'ing the PCV hose back to the front breather fitting will just create a vacuum leak. Don't do this.

 

Where will it create the leak from ?

 

tmk... i dont think that'll work..

 

T'ing the PCV line back to the front breather bypasses the PCV valve from working. The PCV is a small metered vacuum leak. When you splice back to the front breather which is open to the atmostspere in front of the throttle plate, the manifold vacuum which was opening the PCV will now be pulling more unmetered air into the intake. Really bad vacuum leaks can burn valve seats and damage cylinders.

On a FI car it would be a boost leak.
