Lightly blow into EVR...

I've seen this mentioned a few times and I am not quite sure what that means. Yes I can understand light air pressure, but through what orifice - there are 3 of them on the EVR, if you count the cap as a single orifice.

Could someone clarifly what is meant by lightly blowing into the EVR and determining if air if flowing?

The cap is not an orifice, so it's gotta be one of the hose ports.

Hey thanks, that diagram is what I need, it shows me how it works.

Any comment on the vacuum tubes going to it - like how do you replace them/it?

Pull the old ones off and put the new ones on....?

Maybe I don't understand your question.

Doh!

Where do you get them, that's really what I'm asking, since the vacuum hoses are a single unit. If I were to go to the stealership or the parts store what would I be asking for?

You need to post a pic of the hoses then because it's hard for me to visualize them as a "single unit". They aren't that way on my 4.0L.

I checked my Ranger's EVR and I see what you mean now. It does appear that the EVR/EGR hose assembly contains several joints and conjunctions as you follow it along. However, on my '98 the EVR hose runs only about a foot or two and then hooks up to a plastic "joint". I'm able to pull the hose end off the joint and the other end off the EVR to remove the hose.

Another thing to consider is a junkyard. In that case, you can grab the entire EVR/EGR hose assembly.
