the new seals were a pain to put in!! but I made them my **** in the end. All looks well now

 

when installing the new seals id recommend using the metal washer (that is underneath the mini c-clamp and plastic washer) and a 10mm deep socket, then hammer onto the socket to push the seal into place

 

After fixin the seals my gas pedal became stiff when the car is running. It's stiff for half an inch until I apply more pressure, any ideas

 

I got a bit ahead of myself and grabbed some mil.spec TB shaft seals to do this. Did a boost leak test - 35 psi no leaks with original '03 TB seals. Shocked. At least I have them as spares anyway.

 

where would you find these throttle seals for sale?

 

Mil.spec and STM have them for sure. I ruined one of the first ones and had to reorder another set. This next time I believe I am going to try to use the throttle body shaft as a guide. I tried to do it free hand and mangled the metal part of the seal on the TPS side that is recessed. The seal that went in well by throttle cable just tapped in gently and it worked much better.

 

We have hundreds of sets.

They're for sale too!
Give us a call if you want a pair.

Leaky seal?

 

Necro bump.

Do the Mil-Spec seals go metal side in or out?

 

very helpful info. replaced shaft seals with some works seals, but i had such a hard time getting them in I bent them to **** but it was all I had and now I have a pretty big boost leak and my bov is broken lol. Just ordered some mil-spec seals more than one set lol. hopefully I'll get them in right

 

i used a bit of grease. i gently and slowly tapped in the side where the throttle cable goes first. once that was in, i put the shaft through, put the other seal in, then covered it with the metal washer that came off that same side. i used a deep socket that fit over the whole thing and gently/slowly tapped that one it.
i had to use a flat head screw driver to get it seated perfect all the way around.

 

I am putting this info together because I had to install some seals for a friend and I found it difficult because I had forgot how to do it. After I got an email back from Aby and doing some trial and error on my own this is what I would think would work best when trying to install the seals.

This is what I had after I followed his advice.



Note: I found that the Mil.spec seals are slightly different. One has a chamfer and the other does not. I put the chamfered Mil.spec seal on the TPS side of the Throttle Body.

Frist I put the seals in the freezer for a couple hours to shrink them. Then I lubed the seals up with di-electric silicone grease. The M10 bolt perfectly centers the seal around the hole. The bolt doesn't allow the seal to move.

Slid the seal to meet the head of the bolt.


Then tap the seals in one at a time on both sides. I used a rubber mallet to hit them in.


This works on the same principle as the method I describe.

Sort of the same but a little riskier.

 

That pump is crazy! I'm gonna make one tomorrow

 

SUPER LATE here but I noticed that the white plastic washer (once tps is removed) was pretty hard to remove without damaging. For anyone doing the seal themselves in the future, it helped to use needle-nose pliers to bite/hold more area of the white washer rather than something like a flathead which could damage or break the washer completely.
