EGR Help please.
Ok guys, a bit of a dilemma here possibly. I don't know if 87 is a one-year design, but this is kind of a bitch. :)
Here we have the unsleeved 1987 EGR Tube.
Notice the new damn sleeve I bought from Ecklers isn't long enough. :rolleyes:
Notice there is only a flange on one end, and not on the other. '87 uses a clamp on the other end to attach it to the manifold.
Here we have a Hooker 2149 passenger side header. Notice the mounting for the EGR.
Now.... I know that 88 Vettes use the double-flange method, as Fastguy's 88 has it (I looked). What does 86 use?
It looks like I need to get myself a 88+ EGR tube at the tune of $88 or so dollars. Yippeeeeee!
So... what happens if I do this.
1. Put a blockoff plate on both the intake & header. Disconnect the EGR solenoid.
2. Put a blockoff plate on the header, leave the EGR tube hanging in the engine bay connected to the intake. Leave solenoid plugged in. (Lean condition from fresh air vacuum leak?)

Scorp, I just replaced my EGR tube with a new one from the General. It was $70list & $55 to me.
I still have my old EGR tube and it's in tact except that the Al foil is mostly gone from the insulation. If it ifts, you are welcome to use it till you feel you want to spring for a new one. From earlier shots or your top end it looks like it might fit; you'd need two more Torx bolts as I don't have any spares of that size.
Where in MA are you, close to Boston?

Four spark plug wires are routed under that upper EGR tube. The tube insulation combined with spiral wrap around the wires provides protection from the heat. The wrap also assures that the exhaust gasses will be hot enough to trigger the EGR Temp. Switch in the upper end of the tube.
Also the shiny Al surface of the wrap is kinda pretty.

Re: EGR Help please. (drive it)
And remember that if you do want to hook up the egr and have it work, you need to drill out the egr tube on the header! I figured it out after a while....

Re: EGR Help please. (scorp508)
Hello,
This may be a stupid question, but do you need the EGR? The way it was told to me or at least the way that I understood it, the EGR was just an emissions device .
Thanks in advance.

Part of the NYS inspection is a visual check for emissions equipment...OK if the inspector doesn't know it's gone... :D
...But you can never tell just how much they know... :crazy:
