TPS gasket, is it needed?

[pstocker]

I just noticed last night while I glanced at the throttle body from my 88TC engine (just sitting on my bench) that the TPS had a gasket. I am using my SVO throttle body on my engine right now. I do know, as a matter of fact that I did not have a TPS gasket on my 85 SVO engine when I changed the TPS awhile back from the one on my spare 88 TC engine. Should I put this gasket back on my SVO throttle body? Probably so I guess...

don't need one, not sure why one was on there.. nothing goes thru it

With a glance did you confuse the IAC with TPS?

Na, it was for sure the TPS. I have seen this before on 5.0's. I was just wondering because my SVO one did not have a gasket when I replaced it. I guess if the throttle body shaft seal was leaking onn that side, it would prevent a vacuum leak. I don't know. Seems like the goal on any forced induction machine is for zero vacuum leaks, at least for street driven cars!! :-)

never seen that on 5.0's either..strange. there is no air or fluid in that area.

It may be intended to keep fluids from penetrating the unit. You never really know what design folks are talking or thinking about when they do what they do.
