Default throttle body boost leak

I did a boost leak test tonight and found a massive leak out the throttle body. Not sure the exact name for it, but its where the throttle blade shaft comes out and is sprung for the throttle cable. just blowing massive amounts of air.

Has anyone had this problem?

I just found it and have not tried to see if that comes apart yet.

What are the steps of repairing this. Is it simply just a seal that has gone bad?

There is a seal and a bearing on that side of the throttle body. Remove the 2 screws that hold the blade to the shaft, open the TB to wide open and slide the blade out. The remove the throttle position sensor and remove the spring clip. Then pull the shaft out of the TB.

Thats exactly what I was looking for. I figured of course there is a seal in there, just wasnt too sure. Always nice to know something ahead of time.

Do you have a bearing store in your area ? I have a place near by me... McGuire bearing, they match me bearings and seals all the time just from measurements.
