Did I mess up the RVA jacks?

For the first time ever, today my RVA leveling jacks had a bong bong sound as I was lowering them. The instructions say that fluid needs to be added to the resevoir, so I added the proper fluid with one jack extended 6 " as it says.. But, I forgot to have the key on so I could hear the bong sound, and stop adding when the sound stops. I just added a quart of Mercon III fluid and then released the jack. Well..., I heard a fairly loud crack and saw some fluid running down on the ground. I thought that I might have blown out a hydraulic line, or something. But, the leak was only from right where I put it in only. So, I tried leveling the coach with all 3 jacks and they seem to be working fine. Does the system have a relief valve, maybe? Did Anyone else do what I did? I called the RVA factory, but could not reach anyone technically knowledgeable.

The owner of RVA called me back and explained that the excess oil blew out of the breather cap. He said to get a tie wrap and dip it in down into the resevoir to check the fluid level. It needs to be about 1" below the top of the resevoir.
He told me that I didn't hurt anything, except just made a mess on the concrete. His name is Dennis Kay and he is a great guy to talk to.

Thanks for the follow-up; that info might help someone else sometime! Glad it worked out well for you.
