intake manifold death tube question about o-ring

[DrMcDave]

is there an o-ring at the top where it connects to the intake manifold, i have the one on the bottom. I forget if i saw one at the top when i took it apart.

Both ends have one, at least they did in mine.

Both ends.

WOuld not having an O-RIng on Both ends cause an unstable idle or major vacuum leak?

Anyone have the part numbers or if they are available from the dealer?

[modifiede30]

I'm sure the dealer would have them but you could probably find them at a hardware store. Just take the pipe with you and see if they have any o-rings that will fit. I'd also check with local auto parts stores. If you can't find one, let me know, I may have one sitting around from the recent rebuild I completed.

We forgot to put them back in place when we put the head back on my buddy's eta. Been driving it for a week with no problems with the idle or any sign of a vacuum leak.

I believe its possible for it to not have a rough idle, but how does it not leak oil???? You must have the o-ring in there, and forgot. Or it was stuck in the intake and you didn't notice.
I have both o-rings in mine and that bitch leaks. :twisted:

It'll leak like a mofo, the tube has 2 o-rings and a washer that goes on top of the bottom o-ring to hold the spring....i noticed mine didnt have the washer, i replaced everything down there.
