There is an air leak on the throttle body of my friends 1995 3.0. It is where the butterfly valve shaft protrudes from the TB and connects to the springs/cables etc. It looks like there is a plastic washer/seal in that area. Is there a simple and affordable way to fix this? or does he need a new TB? I can post pics if needed

post a pic, i think it can be repaired.

Ok - here is a pic

anything :/
