Discovery 2 V8 4L 2003 with a DIY smoke machine connected to the throttle body:


I'm seeing smoke come out of the part with the spring where the actual throttle pivots.





(That rubber glove is on there tight, nothing is getting past it.)


Qs:


1) Can I repair that? Needs a new o-ring or something?


2) Or do I need to buy a new throttle body?
