Got the expansion valve out today. On the inlet side, there was a small rubber insert that fell into the engine bay, somewhere. The new valve doesn't have one.
How important is/was this small rubber sleeve?

If you are referring to the foam protection on the copper line in the picture, It provides protection and sealing for the copper line between the plastic housing.
Find a piece of foam or a piece of a house door cloth/foam air gap seal to replace.

It's definitely not an o ring or anything that worked its way up to the EV. It is a small rubber insert/sleeve that fits inside the inlet of the valve. It fell out when I removed the old one. It's about 3/4" long tapered black rubber tube.
I was just going to omit it and install the new EV today after flushing the a/c system. The flush was good (no sludge or blockages). But the new EV seems to be the wrong part...it's a mirror image of the correct part with the larger outlet and smaller inlets reversed...doesn't fit. Back to partsgeek for a refund.
Now to find the correct EV for my '86.
The black outer cork/rubber/tar insulation is called "prestite" and is available at any local hvac supply house.
I'd post pics but can't upload since I'm just a "user" and not a member.

In searching for the correct EV, a block style EV keeps coming up at some parts houses. Is this a suitable replacement? How does one deal with all the extra inlets/outlets since the original only has one of each?
