HELP: Internal Solenoid Leaks Killed Us!

This may or may not be good, but I know with oil filters, you should put some oil on the rubber gasket part to seal it better, so adding a little oil to the gasket may help it seal better.

As for wiring, I do know how to do that! The attachment below shows a diagram I drew to help another team a while back. It has more information than you asked for, but it should still help you out.

Don't add oil as some oils will attack the seals. Use a silicone grease like Krytox or a barium based grease like Parker O-Lube.

Your wiring is correct of you want to use it to power 1 side or the other as long as your output to the spike is -1 or 1. Setting the spike to 0 will not move the spool and the valve will not change (this can be used to your advantage).

SMC valves also require 20 PSI for the spool move.

Is the grease required ?

No, but it reduces the chance that you will have a leak.
