I replaced the o rings in the air chambers 2 weeks ago as I had determined that the air was leaking into the neg chamber from the pos.
Anywho went for a ride the other day and about 20km in a noticed the fork was back to its old tricks of sitting low, so this morning took the fork apart, and this is what I found!!

It seems that during the time in the Alps some dirt in the left leg got stuck in the chamber between the stanchion and the positive piston, thus shredding the inside of the stanchion to shit!!
