It was my own fault because i was comparing the PCV setup on my 93 and 94 which is nothing like that. All there is to the system on those is a PCV that vents to the inlet tract. That's it, no other "fresh air" lines.

You're wrong again.

The PCV valve on 5.0's is in the lower intake and the tube connect the lower intake(crankcase) to the upper intake(vacuum source). Its hidden and you can't see it. You can feel the tube if you reach behind the upper intake. The tube from the filler neck to the TB is the fresh air vent.

I'm telling you, go look at it.

Then I have two vacuum sources because my tube (when it was there) from the oil fill goes to the upper intake about 1.5" past the throttle body.

I knew that about the PCV hose though, wasn't thinking when I made the above post.

Can't go look at it. There is nothing but a steering rack underneath the hood of the 93 right now.

Actually, the tube is 1.5 inch before the TB blade.

So that is your fresh air vent. Looks at this pic. Notice the tube connects before the TPS? The TPS is mounted directly on the TB axis.

What brand t/b do you have in that pic

QWKSNKE · 01-23-2005, 10:02 AM

had the wrong vacuum line in my mind. I was thinking of the small one that goes into the intake (beyond t/b).

I still don't see fresh air going into there in a n/a application though. I can see air getting forced into there under boost but not n/a. Just to ignorant it to see i guess

Air goes into it because the other end of the crankcase is hooked to the vacuum port.

At least if you're gonna be ignorant, its only PCV.
