This is the steel tube that runs vertically between intake manifold and engine block. It allows pressure to equalize between the bottom end and the head. It can be a pita to install because it has to be held down while the intake manifold is put into place. The trick is to use a couple small zip ties to compress the spring. Once the intake manifold is in, cut the zip ties.

That’s just how I did it! What did you seal the o-rings with? I thought about using permatex ultra-gray, but ended up just using Plastilube grease.

Didn’t use anything. The rubber o-rings went in dry. Not sure what the school solution is, but the spring ought to keep pressure against the o-rings and keep a seal, as long as everything is clean to start with. At least that’s what I was thinking when I did this yesterday on engine #10.

Correct, no sealant is needed, just use new o-rings each time.

I used the zip-tie trick as well, but wasn’t so lucky. When pulling the zip-tie out, it broke and was stuck behind the spring. Ooops.

I just used my girlfriend to hold the tube down while I installed the intake. Piece of cake.
