Here is a good one...I have a 2014 F550 Four Winds Motorhome with 6.7L that is having an issue that the dealer can't figure out. After 6K miles it has started leaking power steering fluid out of the cap after shut off. There is no leak anywhere in the system and it doesn't to it every time out. I did a test last week to see what exactly is happening, and after shutting off I could see the level in the reservoir start to rise so I went and started back up and watched the level go back down. Any suggestions?
