Question Catch can?

I picked up this catch can a while ago for my 03 D23, but that car is now gone as some of you know.

But I figured I'd put this on my 00 Zetec DOHC wagon.

My only worry is, is it going to affect crank case pressure in a bad way? Or for that matter, valve cover pressure too?

The motor is stock right now, but in the next few weeks I plan to start putting some stuff on. I.E > Exhaust, CAI, header.

I already got 2.5 diameter stainless steel tubing, just got to get header/flex/cat, and a good CAI.


Thanks,

Dj

Yes it will affect pressure. But it shouldn't be in a negative way.

Do be aware that the car may run differently by not having the PCV running to the intake manifold any longer. A good tune will correct this.

What kinda symptoms will I see from disconnecting the vac lines from the intake manifold, and running it to a catch can?

It'll run rich.
The car should be able to compensate. But at first it'll run odd.

Hmmm, it might just be worth waiting until I need a tune from the header and what not.

Seems smarter to just wait, and have who's tuning it, integrate it into the tune to run right?

Sounds like a good plan to me.
