Basically... I was installing TB shaft seals, they wouldn't go in, so I lightly hammered the 2nd one in...

PICS ATTACHED if you look closely you'll see it's a little uneven/bent/chipped
ruined the tb shaft seal in the process and I'm car-less until I get this taken care of

Can this be repaired? Dremel? Not sure how "perfect" the throttle body needs to be...

p.s. ignore the fuzzies inside, just concerned about that inner lip area

 

Doesnt look like you hammered it "lightly". Lol. Anyway it looks like the damage is just on the lip. If anything I would try to file the inside smooth but be very careful. You might be able to get away with just replacing the seals and not have leaks. Put some silicone around the seal too when you install it. Also make sure you do a boost leak test afterward to check for leaks. Good luck.

 

^^^ yea what he said

 

Yeah we're going to try to smooth the inside out a little bit. It's just so damn difficult to get those seals in! All the lube in the world wouldn't get it in!

 

use a very fine file and take your time they can be a little tricky some times

 

Send it to Mil.Spec and let them make sure it's perfect, and they can rebuild it in the process.

 

+++1 . last thing you want is to have leaks

 

Use a perfect size long socket against the seals and then use a rawhide hammer or something that isn't too brutal (but not a rubber mallet) to get them in..

 

i used a screwdriver, sliding it all the way thru then just push down or tapping it . it puts weight evenly

 

might as well send it to mil spec!

 

That's a good idea as well, that way it can't slip out.

 

Thats what ive done on all the ones i changed. Never had a problem getting them in.

 

So what exactly does porting/polishing the throttle body do? What does cleaning it do? Will it make it stick less? Will it improve drive ability? Will it add lots of power?

Is it really worth it to send it out to mil.spec?

I may just clean it myself if that makes a big difference... looks like the throttle body service is just cleaning the throttle body and replacing a few parts.

 

you get a brand new looking functioning TB with upgraded seals for a very good price. not really worth it to port the tb without doing the manifold opening.

this is my stock tb with 50k on it (mil.spec was silent, click it its a video)

 

Very good looking TB!
