So I had this jack laying around and got it working again by replacing all of the seals.

However, it’s got some issue I don’t know if it had it before.

It’s leaking from the main valve right under the cog. Marked orange.

When releasing pressure, there’s an air hissing or leaking sound either at the overload protection valve or the main valve controlled by the handle. I’m not sure
Also the plunger is being pushed out, because there’s pressure build up inside the oil reservoir.

I don’t know if it’s related.
I hope someone can point me to the cause of this because I really like that jack

I don’t want to buy anything new
