Billybuck said: (quoted from post at 07:12:18 04/28/14) Duh, see what you mean Jesse. This is internal. Looking at the manual, it appears to be coming through the seam between the cylinder housing where the safety valve is located and the lift cover. I think this may be the same thing I just dealt with 6 months ago but not "spraying" this time as it was then.
That ram cylinder safety valve under the accessory plate/down in the big hole is shown in the I&T manual to dump into the exhaust tube along with the back pressure via unloader valve, BUT those dump paths, unlike all the other connections between the ram/valve body casting & lift cover, have no sealing such as O-ring or gasket, so it seems free to leak to me & I guess it wouldn't matter as it dumps back into bottom of hyd cavity any way. I might expect your "leak" to be from back pressure/unloader when in unloading )hold or lower, but not lift) or from ram cyl safety during attempted lift if it is stuck open.

Jesse, you may recall I just replaced the cylinder safety valve last Fall. Should the safety valve even open if there is not a problem causing excessive pressure? The source looks to be from the same spot as last fall though it was shooting out probably because I had a bush hog attached when trying to lift.

Quoting Removed, click Modern View to seeNo it should not open. It is only one of 3 sources that potentially dump back through the same un-gasketed path.
