Actually, I just need someone to tell me if I'm thinking along the right lines:
here's the thing:
i got a power tailgate on a work truck.
It has this cylinder which I'm guessing is a fluid reservoir, and on top of the cylinder there is a breather with a simple foam filter.
Mind you I don't use the tailgate that often. I'd guess once every 2-3 days.
Anyways, after the MONTH of rain we had, one of these days at first I noticed a small leak of the fluid from that cylinder thingy(breether).
At first I panicked and thought my tailgate is f$%#'ed, put it away and didn't use it at all, in fear of burning out the motor, pump or something. I figured I'll get it checked out.
But Sunday was so nice, I figured I'll check it out myself.
So I did and I noticed couple of things:
1.the fluid that came out, only did at the very end of lowering cycle, and it was very foamy and milky-suggesting water presence.
2.After lifting and lowering about half-dozen times it stopped leaking alltogether.
So I figured that over the rainy days a bunch of water got mixed with the fluid, due to shitty placement of the breather, causing the foaming, therefor increased volume, therefor leakage.
I'll still get the fluid changed, but is this a correct conclusion?
THe gate seems to be working fine, no more foaming and leakage today.
Does hydraulic fluid foam up like that if it's mixed with water???
