Well, I did not pay enough attention as I was taking this engine apart. I cleaned, blasted and painted the intake tubes and the "intake distributor" (please correct me if I have mis-named). Anyway, I am a good 1/4" off center on the #3 cylinder intake tube, left tube. This can't be good or right, can it? I can get the short rubber hose on,
this kind of offset will leak right?

the 1/2 side lines up nicely

Facts:
The plenum is installed correctly.
There are right and left intake runners.
The runners in your pics are not for a 2.0 (they wouldn't bolt to the heads and they would be way short).

Conjecture:
Your first pic shows the passenger side plenum tubes the same length. The tubes on the runners are not the same length.

On a 1.7 plenum, the #3 tube is about a half inch longer than #4.

In post #10 it "appears" the #4 tube is sticking inside the plenum? It also appears that #3 runner is touching the plenum.

I don't have a 1.8 plenum to compare with physically, but comparing the two visualy, it looks like the 1/2 side of the two plenums are about the same while the 3/4 sides are much different. The 1.8 plenum is much "fatter" than the 1.7 on the 3/4 side.

More conjecture: At least one of your intake runners is from a 1.7.

The picture in post 10 is angled such that the 3/4 tubes look different, plus the 3/4 tubes are not bolted so they are lying under the plenuem tubes....Basically the tubes are exactly the same with the expection of the one tube that will not line-up with a plenum tube when mounted on either side. They came off of this engine and were formerly bolted to 1.8 liter heads. Question will this leak, will it be a problem?
