Your friendly local Chevrolet dealer should be able to get that part for you, that's where I got one for my '87. :confused

You can pick one up at almost any parts store for about $3. Look in the "Help" product line. I broke mine while rearranging some vacuum lines but had no problem finding one. How are your lines tied together if the check valve is missing?

Ok, from what I remember (my Vette's in the shop). One side goes under the intake to the passenger side. One side disappears down by the base of the firewall, I think to the cruise control. And I think the other side goes towards the front of the intake to a vacuum switch by the thermostat.

I've been looking though my service manual and can't find anything on vacuum lines (they're there, I'm sure; just can't find them). Looking at that picture again, it looks different than my car. That's up by the throttle body, right? I have a totally different (much larger) vacuum switch under the TB, with that three-way check valve back almost under the distributor (and yes, one of the vacuum lines goes over towards the battery and cruise control). When I get my car back, I'll look at it again. However, you can still get that valve at most any auto parts store, and hard plastic vacuum line is cheap (although some people here switch any hard line that breaks to the soft pliable kind).

Well , My 85's original (early build) and I don't have a check valve there just a T one line goes back under the Throttle body to the EGR sol and the othe goes front to the carbon canister for the fuel vapor purge. right behind the bumper.
