Hi guys,I'm re-assembling the intake manifold and I have to put the metal pipe back in at the bottom of the manifold. I've got new o-rings and 2 metal washers plus the old spring. In what order do the metal washers go?I know theres an o-ring at the top and bottom and the spring goes at the bottom but not sure on the washers.Also is it better to fit the pipe first or can it fit in after the manifold is on?

I should think you put the washers each end of the spring.

Tie the spring fully compressed with a couple of bits of fishing line, grease the o rings at both ends, and push the assembly down into the block. When the manifold is bolted on, holb the tube with one hand, cut the fishing line with the other, and guide the top o ring up into it's place.
Washers as in post above.

Thanks guys
