My Indy told me that if your hydraulic reservoir is misting and leaking around
the top portion, it's a sign of a dirty/clogged filter.
Yes, I know that the oring on the lid can and does leak.
I tried a new oring, still leaking.
Today I installed a new reservoir.

Waiting a few hundred miles to see if it's still dry.
Anyone else hear be clogged filter theory?
