I was replacing the distributer cap and rotor the other day and noticed this under the plug wires.



I put my thumb over the hole while the wifey cranked the engine but could not feel any vacuum and the car isn’t running right now so I can’t check the hole for vacuum under those conditions. I have never seen that happen with just the wires rubbing against the intake, other harder things but not just a spark plug wire. But anything is possible I suppose.

Now my question is,
How in the hell do I fix it, or do I need to?

I don’t dare try and weld it on the car, besides it is too thin to weld there with anything but a Tig welder, that I don’t have.

But I was thinking of good old JB weld, hey it was made for this sort of stuff wasn’t it.

I have no clue what it is both of my fieros have tue exact same spot. Tho with the thickness of the plenum it will never make it all the way thru.

They all have it. It's from making the bolt holes to mount the throttlebody. Not a problem.

It's just where the factory drilled and tapped the throttle body mounting bosses a little too deep for the throttle body mounting screws. The hole doesn't interconnect with the bore of the plenum so it's OK.

(Darn that RWDPLZ... beat me to it!)

X3. Many have it. Not a problem.

x4...never seen one without it.

How about that.
I've never even noticed it.

Mine didn't have it, so I put one in.
