CFI Eyebrow Gasket (zak)

[boway]

Hey zak,

Sorry I don't have a scanner. I will try to explain more about the Eyebrow Gasket.

Eyebrow Gasket Top Side:
http://ford.webbywarehouse.com/image/eyebrow1.jpg

Looking at the picture, the rear is at the top. It is made from .010" stainless steel shim stock sandwiched between two gaskets. The throttle bores are 1 5/8" side to side and 1 3/8" from the curve in the front to the straight in the rear. That leaves a 1/4" blocked in the rear. This gasket goes between the intake and the insulator.

I checked all my CFI throttle bodies and the only ones that open fully are the ones that came off of the Police Cars with the Eyebrow Gasket. Maybe part of the fix was bending the stop tab on the linkage so it would open all the way!

To tell if a car has this gasket just lean over the fender look down into the throttle bore with throttle wide open and you will know it when you see it.

Any more questions fire away.

TTYL, Binnie

Binnie, can you check the throttlebodies that came w/eybrow gaskets, and see what the part number is on the flange? Were they E5ZE-DA ? The "newest" one I have is -CA.

Thanks for the design info on the eybrow gaskets these should be easy to make, I will talk to some sheet metal folks.

Thanks - I am especially conerned about correcting this if I attempt a GT40P long block swap . . . . .

[zak]

Binnie one other question, were the donar cars you found full sized Crown Vic, or mid-size LTD?

Thanks - zak

[boway]

Hey zak,

Both cars were mid-size LTD's. Here is the Vin #'s 217551 and 217559. Build date 5/85 on both. They are DA throttle bodies.

Is that one that thing is for?! I have one of those plates and it fits the N/A 2.3 and would allow for a 2 barrel carb nicely.

[zak]

mfpmax, if the measurements match those boway posted above and you want to part with it I might be interested.

binnie, my VIN ends in 2098XX, so in between your car and the 2 donar cars you found\, explains the later -BB revision on my intake casting. From the serial number alone souds like they fiddled with the intake casting and then when it did not work they went to the eybrow gasket.

Since my throttlebody has to come off again (used fuel pressure regulator I swapped on is not holding pressure, and is not adjusting proerly think its gummed up) I may try to track down a DA thorttlebody and eyebrow gasket.

Its not really mind to give up. Sorry.

the eyebrow gasket is a fix for the front two cylinders running lean at WOT right? i have a V6 cfi and it has a plastic spacer that has the bores tapered to a smaller diameter. is this the same idea? mine was replaced with a later spacer per a tsb.

[boway]

Hi V6DR,

Yes, the Eyebrow Gasket is for the front cylinder lean condition. I was not aware that the 3.8 had the same problem. Do you have the TSB or the number for it?

Thanks, Binnie

[V6DR]

the tsb i was referring to is 87-3-10. i can scan it if you want. when it took off my throttle body the first time i noticed the part number on the spacer begins E6SE but my car is an 84.

[boway]

Hey V6DR,

A scan would be cool.

Thanks! Binnie

Hmm... and now to awaken an old thread!

There were not updates on this eyebrow gasket thing that I tohught were being made up.

I just recently ran into James Petersen a the Fab Fords Forever show at Knotts and he just happened to have one of these SS Gaskets on him. So I did a trace and measurements and gave the sheet (paper) to a friend.

This friend has a plasma table and will be programing the gasket into his computer and cut a sheets worth of these things out. How big the sheet will be... I dunno. But he will do it as soon as he can.

I'm sure the cost of this will be low. I'm expecting possibly 10 bux.... but we've not gotten there yet. But it will be made as close to factory specs as posisble... Stainless steel and all.

I will keep you all informed.

[zak]

Hey, thanks Marz I am in for one.

ANyone ever compare a DA throttlebody to a BA or CA? I have yet to see any difference between the BA and CA bodies I have here (took a caliper to them),

Marz, amd thinking the quarter inch "eclipse" of the throttle bore might be too much . . . . .

zak

[boway]

Hey Marz,

Put me down for two, maybe more. If you need an original for a pattern let me know.

TTYL, Binnie

[boway]

Hey zak,

Re-read my post from above about the DA throttle bodies.

You mean on the plate my friend will make?

[Marz]

Good news

My Freind Louie is nearly done with the eyebrow gasket. Once the final design is done he will see just how well his plasma cutter can cut a small gauge SS sheet. He says the thin gauge sheet may not work well with his plasma cutter... but he'll see how well it'll do.

the price and the amount he can make are still in the talks....

I'll keep you all informed.

Also... what other CFI vehicles would this work on? We'd like to know so we could sell them to other CFI cars that may need them.

Thanks

i am gonna ask a dumb question...but what the hect you 'all talking about?! the link does'nt work and this is the first I ve heard of this. I have an 84 CFI car,so I am concerned with this and any new pics you can post up? Thanks.

The eye brow gasket is a sheet of Stainless Steel with "eye brows" toward the back that helps "deflect" the fuel from reaching the rear cylinders. This is because the rear cylinders tend to run more rich than the front with the CFI cars. The eyebrow gasket helps prevent this problem.

Even though the making of this gasket is taking a while... my friend is working on it. Sometimes to make things right the first time... it takes a while specially when it comes to cutting them out with a plasma cutter by a computer. So he needs to get the demensions correct. He also has several other projects that he's working on... mostly mustang stuff.

[Marz]

Ok Guys....

This may be it! All I have to do is go to the salvage yards on saturday and test fit a couple of paper mock ups and see what version he did fits best.

It's not as perfect as the original Ford version but it will still do the same job as the original. It should also be made from SS as well.

Louie and I (mostly Louie) are trying to get this as exact as possible.

Can somebody who has one of these eyebrow gaskets tell me what gauge the metal is? I think I know what it is.... just want to be sure.

Thanks all.

[Marz]

Looks like we may have finally found our SS eyebrow gasket. I test fited a paper version and it seems to fit nice. He'll be cutting one out soon and I'll test it on my LTD LX before we know for sure that it's totally correct.

It's not exact... but it's close.
