The reason I opened the butterfly-valve in the first place, was because I found the TPS full of oil. Couldn't figure out where that came from. Oil can enter the TPS via the throttle shaft area - because it is not a snug fit (the TPS shaft-hole has slots in it). The TPS worked fine despite the oil - but I put a new one in after the cleaning.

I too expected there to be a rubber-seal on both ends of that shaft, but I found only one in the throttle-link area. The TPS end didn't have any. I have a spare throttle-body and that too dosn't have a seal on that end.
