intake tube alignment, 3/4 tube to the distributor is off Options

[TheCabinetmaker]

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.

I think that you may be using thicker intake gasket, where did you get them from?

Gasket set came from Type 4 store. They are the same on both sides and 1/2 fits nicely. It may look a bit different in the picture, cause I don't have the intake tubes bolted down on the off center side.

My main question here is will this leak? If so, is that an issue? And then of course, how do I fix?

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?

Here's a couple of pics of my 1.8L engine showing the runners. The plenum on yours looks to be mounted like mine.

The parts you posted apear to be 1.7 parts, not 1.8

I never looked that close, but James is correct. That is a 1.7 plenum. The last pic on that post shows the difference i'm talking about.

Malcom, I don't doubt those are the parts you took off but still does not mean they are correct.

To answer your question, if you can get the sleeves on and clamp them, then they probably won't leak.

I've tried to use the 1.8 runners on the 1.7 plenum. They just dont fit.

Correct. The FI is from a 71 1.7L bolted onto a 1.8L engine.
