Correct way to install TB gaskets and seals??

[tsi1991awd]

On the TB and elbow gaskets, there are raised "rubber" parts. Does the rubber part face the throttlebody on the TB to IM gasket? And does the rubber part face the elbow or TB on the TB to elbow gasket?

Also, my shaft seals are coming in today from Kaman...how are those installed? I have read something about a lip or something but didnt see any pictures??

I just put my IM and TB together but I didn't use gaskets for the TB and TB elbow (I just used gray RTV between those two). For the IM to head I used a gasket which had these raised rubber parts like yours. The gasket could only go on one way because it was not symmetrical. The TB to IM gasket should not be symmetrical so there should only be one way it can go on, as for the TB to TB elbow gasket, both of those surfaces are flat with no crevices like the TB to IM, so that one probably doesn't matter. If you can't find which way it is supposed to go for sure, and you really want it to seal good, you can use a little gasket sealer carefully on the side that doesn't have the rubber just to make sure.

As for installing seals, just tap them into place with a soft, flat instrument (a small piece of wood) and a hammer and tap it around and around until it is in the same position as the original. Ideally, you can find a socket which matches the seal perfectly and tap it into place with that. Also, if it has a "lip" the lip should face the outside as it keeps dirt from getting to the seal and possibly ruining it.

I figured out that the green raised rubbed part goes against the TB or the tb to IM so it covers the small ports. The Tb to Elbow I am not sure bout...does it go on the elbow or toward the TB?

I know there was major boost leak from the seals because when i tore the tB apart and looked I didnt see much rubber...so I pulled the casing out and maybe 1/4 of the "rubber" was still there except it was now hard plastic! Going to put everything back together today. Should be fun (since I forgot to mark the white spring wheel and the arm)

Thanks for the link...except I know how to do the install. Was just saying the spring portion and arm might be a bit tricky since I didn't mark anything except for the line across the spring itself.

Also, Kaman ####ed up and there's only one seal. They were in separate boxes and one box was empty...so now it won't be until Wednesday until the other one comes. Pissed me off.

But what about the throttle body gaskets, namely the TB to Elbow?

 

[snowborder714]

For the springs, zip tie both ends together, grab the zip tie with vice grips, and rotate 2 rotations from where they naturally sit. Then play with the white plastic piece and the cable bracket to make sure the nubs on the bracket line up with the holes on the plastic piece.

I'm not sure on what side the raised parts go on. And they're only on one side? I'd probably guess they go away from the throttle body.

Well when I took the white plastic off, the springs unwound and now they're completely off, guess I will have to scrunch them back together and whatnot.

The raised part for the TB to IM goes against the TB where the vacuum ports are...the one for the TB to Elbow, not sure where that one goes....it circles around the hole for the TB. And it's only on one side.

 

[snowborder714]

Put on the green spring first (should be obvious by the ends which goes down), then put the silver spring around it, and then put the white plastic part on. Make sure to put the top end of the green spring through the hole in the white plastic piece.

I'd say just install the gasket. It probably won't make a difference either way.

Like you said, the tb to im gasket can only be installed one way, with the raised part towards the tb. The logic I use is that if the raised portion is against the tb on that side then it should be for the other gasket too. Either way you install it I'm sure it will be fine, but I personally put the raised portion on both of the gaskets against the tb. FWIW, I also use copper spray on those gaskets.

Do you think I can hook the green spring to the TB and hook the silver spring to the TB, then hook both onto the white plastic piece and turn it that way, or does it need to be turned before the white plastic piece is put on?

Thanks, I will put the TB/Elbow gasket with the raised part facing the TB itself. Good call on the copper spray as well.

You're correct. Maybe my statement was worded bad. You set both springs on the throttle body, install the plastic piece, then rotate the springs 2 full rotations.

Do I put the plastic piece and arm on (bolt it down with the nut) then wind the spring around it? Or leave the arm off and just spin the plastic piece 2 rotations then bolt it down?

Also, do both springs go into the same hole on the white plastic piece? Because I believe there are two holes and I don't remember how I took them off.

 

[snowborder714]

The cable bracket gets installed after winding. Check out how it'll fit in with the nubs on the bottom. If you're unsure, it'll probably take you a while to figure out what it isn't sitting flat. Once you get them lined up, bolt it down.

Is it sad I just put 4 of these together on Saturday and I can't remember if one or both springs go through the plastic piece? I think it's only the green spring that goes in the largerish hole and the silver is on the outside, but the ends sit one on top of the other.

Should I get a couple pictures of the springs and the plastic piece so maybe you can tell me? I know the larger hook portion of the springs goes on the TB itself...I know there are two holes on the wheel, one larger than the other. Not sure which goes where or.....

 

[snowborder714]

Sure, you can do that if you'd like. Either that or maybe turbosax2 can chime in again since he has the throttle bodies we just rebuilt with him.

If i cant find out i will post a few pictures. I know the green spring goes inside the white wheel and the big spring goes outside. I wont be able to put it together until tomorrow since the new seal wont be in until then. But at leat I can get it all figured out.

 

[tsi1991awd]

I was looking at the spring and wheel earlier. There are 2 small holes in the side where it connects to the arm (the "dowels" on the arm go into the plastic wheel) Then there is one big hole...do both of the spring "hooks" go through that hole or just the green? I looked at the thing a couple hours ago and already forgot what it's like.

On a sidenote, take a look at my old seals. Hard to get a pic of them, but this is the worse of the two. The first pic if the "inside" where the seal is almost completely gone except for 1/4 of it which is hard plastic. The second pic is the "outside" of it, you can see where the rubber turned to plastic.

Did you look at the link turbosax2 posted above? That shows very well how to install the springs and plastic piece.

Yep, that's what stock seals look like. They don't get reused.

Saw the link...there are only a few pics on page 3...unless im missing something? And even if you have a boost leak there and it doesnt affect boost levels, will it make the car run better once its fixed? Because my boost was never affected but i could hear air being sucked in when the car was idling

This post shows how the springs seat with the plastic piece.

Thanks, something's been up with my phone and it doesn't load all the pictures on forums. Only some here and there. I think my plastic wheel looks a bit different than that, but I will get it figured out. Thanks for your help guys, I will let you know how it goes.

 

[tsi1991awd]

I got the seals in...but question here - is a small bit of rubber supposed to come off from the outter edge?

It was a really tight fit to get in and after they got in, there was a really thin sliver of rubber that was around the outter edge of the seal. Normal??

 

[snowborder714]

Yes, I've had this happen before, especially with the seals from Mach V. They're just that tight. As long as there's not a huge chunk that came out, you should be fine.

 

[tsi1991awd]

Alright, thanks. It was a very thin sliver from the outter edge. Nothing from the inner portion
