Jeff-C-IL Posted September 3, 2020 Share Posted September 3, 2020 If the cylinders are not leaking out the end (internal seal problem) you need to repair the valve. One of CIH techs can probably tell you exactly---I think there is some kinda little poppet that is sticky or leaking. Link to comment Share on other sites More sharing options...

SDman Posted September 5, 2020 Share Posted September 5, 2020 The yellow oil is the trapped oil in the header lift cylinder circuit in the header valve. I think I circled all the possible places for oil to leak internally in the valve. Link to comment Share on other sites More sharing options...
