Vehicle - 1997 Dodge B3500 5.2 Roadtrek RV conversion van. My mechanic has informed me I have a vacuum leak at the intake manifold (engine idles @ 1000+/- rpm, idle throttle valve okay) and that I may need replacement manifold, a no longer available Chrysler part; are they available elsewhere?

Any insights in general relative to this issue? I am confident he knows his "stuff." He has suggested I may end up just "living" with the high idle due to age and availability of parts. I would rather not!

Thanks!

I would say he doesn't know his stuff! If so he would have known about the plenum issue. Can find used manifolds on craigs list all day long.

 

318 parts are plentiful--enjoy that roadtreck

 

Nibroc - Re Roadtrek, I do! Being a 318 is part of the positive aspects.

Moparite - My research generated some good input about plenums which I shared with mechanic. As soon as I mentioned it, it all came back and he vigorously agreed, that's the problem. I truly believe he just didn't think of it. I've "been there, done that too." I think that's called can't see the forest for the trees. A plenum repair kit is somewhere between parts supplier and my residence as we speak.

To both thanks for the response.
