The spot between the bottom of the Throttle body and the TPS.....The Shaft location where the TPS slips on, that is where the leak is coming from per the Smoke Test I did.

I believe the butterfly shaft bearing in the throttle body itself seems worn.I doubt there is a fix without replacing the throttle body.
Mine is doing the same and leaking oil to my tps, not a big issue i guess. -
It's likely that the bearings/seals on the throttle shaft are worn. You can rebuild it, there's a writeup either here or a video on YouTube about it. It's kinda tricky, but doable. Also, any used TB is probably going to be leaky too. Good luck!sigpic

Thanks everyone above for the bad news. This car is the gift that keeps on giving (being sarcastic lol)......I located the video and this certainly is a pain. Here is the video on how to replace the bearing:

I think if you really need to do it the easy way try to find a small rubber seal that will fit (or fabricate one from a bigger seal) and stick it between the bearing and clip the rotation is not that fast and the bearing on 80s car still ok just not sealing.Comment
