Part number: 20v intake gasket

[skit]

Hi,

Looking for Toyota part number to order the gaskets that go on the "exit side" of the individual throttles (i.e. the face of the throttles closest to the head, with 3 bolt holes). I have a diagram showing the gasket for the throttle intake side (i.e. between the airbox and the throttles, part number 17179A, but I don't need that one.

I have a T3 adaptor, am doing the quad conversion to my 16v at the moment.

I have searched club 4ag, this forum and others, but didn't find it....anyone know the part number?

they for a blacktop parrot? they dont look like my silver ones. what are they worth out of interest?

if you cant find them a smear of that blue RTV gasket shit might get you out of trouble

YES Parrot - They're the ones!

I need the silvertop version though - which are yours?

hi all

thanks jess

Can't confirm exactly as I got these for $10 of trademe a while back. I have late silvertops put away for a rainy day but they are still on the manifold.

If you want me to pull one off to check, let me know and I will post up a photo of the rear of the TB. Presumably there will be a gasket in position to check too.

I am getting a T3 manifold in the next couple of months anyway so they will come off eventually.

Got curious so pulled one off

So the ones shown above in the packet are correct for these TB's, and I trial fitted one of the new ones to be sure.
As I said, I believe these are late silvertops from memory.

They have this manifold outlet which will enable you to check.

Thanks guys, esp Parrot for taking the trouble to remove a t/b to inspect.

I don't have the 20v manifold to check how it compares to yours Parrot. Also, my quads were given to me without a linkage. I've heard that different series (early/late??) had single or double type throttle cable linkages, but I have only ever seen the double ones. I have no idea how to identify a early/late throttle design with what I have to work with.

So then, are the "late" 20v throttles a larger diameter (same as black top ones perhaps)? All the T3 silvertop adapters have been machined to the same I/D, and I never specified a particular bolt pattern to Gabe when I ordered it..... so I would think that if the I/D is the same, and the tri-bolt pattern is the same, then I should be able to get away with any silvertop gaskets, regardless of the series of engine.

If the exercise is not so straight forward then I shall cut my own, I don't fancy ordering incorrect bits.

Thoughts guys?

I'd say you would just need to make sure that none of the air bleeds are covered. I dimly recall there was some variation in that area between the various types.

When I bought mine, I searched and found a thread somewhere that showed the variation between each, but can't recall where.

I had a search last night and found a few web pages with some differences. It seems that most of the changes were in the manifold between the quads and the head.

Thanks for your help.
