Is there water in my forks? Hi I bought a used downhill bike with a 2009 Marzoochi 66RCV fork. I hear a gushing sound whenever I compress the forks. At first I thought it was oil but am just wondering and don't want to ruin anything. Is there anything i can do besides taking apart the fork. Thank you for any answers.
I would say it is most likely oil moving through the valves. If you are concerned about more water getting into the fork you could clean out your fork seals with a piece of old camera film. 

Given the year of the fork, I suggest taking it to your local bike shop. It cannot hurt to service your fork and support the people that support riding in your area!
